Objective: The aim of this study was to criticaly review the published literature regarding the clinical aspects involved in the rehabilitation of edentulous patients using Branemark protocol and overdenture prostheses. Methods: An active search was conducted in the LILACS, MEDLINE, PubMed, and SciELO databases using the descriptors: "Coating for dentures" (Overlay Prosthesis and Overdenture) and "Implant-supported fixed dental prosthesis" (Protesis dental de suporte implantado, Dental prosthesis, and Implant Supported Prosthesis) in Portuguese, English, and Spanish between January 2000 and October 2014. Results: The following parameters should be considered when selecting between Branemark protocol and overdenture prostheses: bone support, lip support, lip-line, upper lip length, oral mucosa conditions and size, alveolar ridge contour, crown-bone ratio, interarch space, and speaking space. Overdenture rehabilitation can provide many benefits to patients, such as prosthetic retention, stability, comfort, and improved aesthetics. Conclusions: This study highlights the need for a thorough individualized treatment planning to ensure that fixed prostheses and overdentures have an excellent prognosis when used appropriately in suitable patients at the appropriate time.

Abstract The study aimed to identify the changes in the provision of dental prosthetics procedures in the Brazilian primary care. Secondary data from the Brazilian “National Programme for Improving Access and Quality of Primary Care” was assessed and three similar questions related to dental prostheses execution that were answered by the same 9,698 oral health teams, in 2011/2012 and 2013/2014, were compared. There was a 4.3% increase in the number of teams that identified individuals with prosthetic needs; a 0.8% increase in the number of teams that performed impression for prosthetic purposes; and the number of teams that reported performing dental prostheses consultations increased by 0.6%. Overall, there was a small modification in the number of teams that provided dental prosthesis procedures in Brazil.

Cleft palate/lip is a frequently occurring congenital anomaly; one in every 800 births results in such a problem. Different treatment options are available for replacing missing soft and hard tissues, including removable dental prostheses, fixed dental prostheses (FDPs), and implant prostheses. In the literature, according to different authors, there are different option standard for prosthetic treatment of cleft palate/lip. Some authors report that removable prosthesis is the choice in such cases, some of them regard conventional tooth-supported FDPs as a standard of care. In this case report, the prosthetic treatment of congenital cleft palate/lip was described. Upon the choice of the patient and patient’s agreement, the direct construction Fibre-reinforced composite (FRC) adhesive bridge with pink composite gingival epithesis was performed.

Full textAbstract:
The postcuring process is essential for 3-dimensional (3D) printing of photopolymer-based dental prostheses. However, the deformation of prostheses resulting from the postcuring process has not been fully investigated. The purpose of this study was to evaluate the effects of different postcuring methods on the fit and dimensional accuracy of 3D-printed full-arch polymeric fixed prostheses. A study stone model with four prosthetic implant abutments was prepared. A full-arch fixed dental prosthesis was designed, and the design was transferred to dental computer-aided manufacturing (CAM) software in which supports were designed to the surface of the prosthesis design for 3D printing. Using a biocompatible photopolymer and a stereolithography apparatus 3D printer, polymeric prostheses were produced ( N = 21 ). In postcuring, the printed prostheses were polymerized in three different ways: the prosthesis alone, the prosthesis with supports, or the prosthesis on a stone model. Geometric accuracy of 3D-printed prostheses, marginal gap, internal gap, and intermolar distance was evaluated using microscopy and digital techniques. Kruskal-Wallis and Mann-Whitney U tests with Bonferroni correction were used for the comparison of results among groups ( α = 0.05 ). In general, the mean marginal and internal gaps of cured prostheses were the smallest when the printed prostheses were cured with seating on the stone model ( P < 0.05 ). With regard to the adaptation accuracy, the presence of supports during the postcuring process did not make a significant difference. Error in the intermolar distance was significantly smaller in the model seating condition than in the other conditions ( P < 0.001 ). Seating 3D-printed prosthesis on the stone model reduces adverse deformation in the postcuring process, thereby enabling the fabrication of prostheses with favorable adaptation.

Full textAbstract:
The main cause of prosthetic stomatitis belongs to the chemical and toxic action of the residual monomer of the prosthesis base, which is a protoplasmic poison. Occurrence of prosthetic stomatitis depends not only on quality of production of prosthesis in laboratory though at non-observance of technology indicators of residual monomer can reach 2-5%, but also at individual intolerance at its minimum concentration in a prosthesis after polymerization - 0,2-0 .5%.
The aim of our study was to increase the effectiveness of orthopedic treatment of patients with prosthetic stomatitis by coating the plastic of removable prostheses with nanoscale materials.
Materials and methods. To solve this goal, we studied the condition of the tissues of the prosthetic place of patients with prosthetic stomatitis with prosthetic removable prostheses with modified plastic. Orthopedic dental treatment of 50 people was examined and performed, including 25 people (the second group, prostheses were not covered with nanoparticles) and 25 people (the third group, prostheses were covered with nanoparticles). The first control group consisted of 10 people without signs of pathology.
Prior to treatment, all patients had removable acrylic plastic dentures. The reason for seeking orthopedic care was a violation of masticatory function and the inability to use previously made prostheses due to the development of pain in the soft tissues of the prosthetic place. Complaints of pain were observed in all patients of varying intensity, impaired fixation and stabilization of the prosthesis due to swelling of the mucous membrane of the soft tissues of the prosthetic place, heartburn and dryness were observed in 90% of patients. Complaints were also about speech and aesthetic defects.
Patients of III group after two weeks of using prostheses were coated with the inner surface of the prosthesis, which is in direct contact with the mucous membrane of the prosthetic place with molecules of fullerene C60, by magnetron sputtering. For this purpose, the prostheses were removed from the patients for several days and returned after the coating with the nanomaterial, after which the observation was continued.
The results. After coating the prostheses in patients of group III with Fullerene C60, we observed the disappearance of inflammation of the mucous membrane under the prosthesis and patients noted the absence of discomfort. Рatients in II group had a negative dynamics in 80% and had diffuse inflammation of the mucous membrane under the prosthesis. Within 3 months of use, 18 patients (72%) in II group reported that they stopped using removable dentures during the day, due to unpleasant pain under the prosthesis,
and used only during meals and during conversations. In contrast to II group, patients in III group did not notice discomfort when using plate prostheses.
Conclusions. Obtained in the course of the work convincingly prove the effectiveness of the use of removable plate prostheses with nanocoating for the treatment and prevention of prosthetic stomatitis in patients. This is evidenced by the data of objective examination and the disappearance of complaints from patients.

Full textAbstract:
The objective of the present study was to investigate the effects of various types of fixed prostheses on periodontal tissues and explore the association of gingival biotype and gum recession in relation to prosthesis types. The study participants (N = 95) were divided into three groups based on the type of dental prosthesis: Group-I: cobalt-chrome (Co-Cr) ceramic prosthesis fabricated by the conventional method (n = 35); Group-II: consisted of patients with Co-Cr ceramic prostheses fabricated by a computer-aided design and computer aided manufacturing (CAD/CAM) technique (n = 30); and Group-III: zirconia-based prostheses fabricated by the CAD/CAM technique (n = 30). Following the use of prostheses, periodontal examinations were performed using the Community Periodontal Index (CPI) and Modified Approximal Plaque Index (MAPI). In addition, the gingival biotype was examined using a probe transparency method. The Statistical Package for the Social Sciences (SPSS), Version 20 (IBM Company, Chicago, IL, USA), was used to analyze the results, and the significance level was set at p = 0.05. It showed the MAPI results after the use of prosthetic rehabilitation for 12 months of periodontitis in 87.9% ± 15.4 of patients in Group-I, in 80.6% ± 17.97 in those in Group-II, and in 62.5% ± 21.4 in those in Group-III (p < 0.01). The CPI index results indicated a high prevalence of periodontal disease in all groups. The number of people with healthy periodontium constituted 17.1% of patients in Group-I, 24.2% in Group-II, and 37.1% in Group-III. Our study concluded that prosthetic treatment with periodontal diseases showed better outcomes while using dental prostheses fabricated by the CAD/CAM technique compared to the conventionally fabricated dental prostheses. The thin gingival biotype is more often associated with gingival recession than the thick biotype.

"Strategic Use of CAD-CAM Interim Restoration for the Recovery of the Vertical Dimension of Occlusion in the Posterior Partially Edentulous Jaw." Applied Sciences 10, no. 21 (October 31, 2020): 7735. http://dx.doi.org/10.3390/app10217735.
Full textAbstract:
Occlusal contact loss occasionally occurs following the placement of implant-supported fixed dental prostheses in the posterior region. This complication is caused by the change in the vertical dimension of occlusion after the recovery of mastication. The change is probably related to the prosthesis sinking phenomenon and previous mandibular dislocation. The use of interim prostheses could help re-establish the vertical dimension of occlusion. The definitive prostheses can then be accurately fabricated using digital techniques in the newly established vertical dimension. In this case report, we introduce a protocol incorporating a computer-aided design and computer-aided manufacturing (CAD-CAM) interim prosthesis and digital techniques to minimize the occurrence of unexpected initial occlusal changes in the prosthetic treatment of implant-supported prostheses in the posterior region.

Full textAbstract:
Background: The treatment plan of prosthetic restorations supported by dental implants requires comprehensive scientific knowledge to deliver prostheses with good prognosis, even before the implant insertion. This review aims to analyze the main prosthetic determinants of the prognosis of implant-supported prostheses. Methods: A comprehensive review of the literature was conducted with a PICO (Patient Intervention Comparison Outcomes) question: “For partially or complete edentulous subjects treated with implant-supported prostheses, which prosthetic factors could affect clinical outcomes?”. A literature search was performed electronically in PubMed (MEDLINE), Scopus and Cochrane Library with the following equation [PROGNOS * OR RISK] FACTOR IMPLANT DENTAL, and by hand search in relevant journals and throughout the selected papers. Results: This revision was carried out based on 50 papers focused on several prosthodontics-related risk factors that were grouped as follows: implant-connection, loading protocol, transmucosal abutments, prosthetic fit, provisionalization, type of retention, impression technique, fabrication technique, and occlusion. More than a half of the studies were systematic reviews (30%), meta-analysis (16%), or prospective evaluations of prosthesis with various kinds of events (18%). However, narrative reviews of literature (14%) and in vitro/animal studies (16%) were also found. Conclusions: The current literature provides insufficient evidence for most of the investigated topics. However, based on the accumulated data, it seems reasonable to defend that the best treatment approach is the use of morse taper implants with transmucosal abutments, recorded by means of rigidly splinted copings through the pick-up technique, and screwed by milled prosthesis occlusally adjusted to minimize functional overloading.

BACKGROUND: This trial aims to study the difference between prostheses screwmented on full-arch implants using the intraoral luting cement technique on titanium bases versus transmucosal abutments in terms of prosthetic complications. MATERIALS AND METHODS: Twenty patients were recruited in this trial, there were mainly two groups. A screw-retained full-arch implant-supported prosthesis was constructed over four dental implants on upper or lower jaws. For the control group, multiunit abutments were used to construct a screw-retained prosthesis. As for the experimental group, Ti-base abutments were used over the dental implants to construct a screw-retained prosthesis. In both groups, the prosthetic framework was made using polyether ether ketone (PEEK) material and luted intraorally over the titanium sleeve using resin cement. A binary outcome of prosthetic complication was taken in 6 and 12 months. Abutment screw loosening, prosthetic screw loosening, prosthetic screw fracture, abutment screw fracture, veneer fracture, framework fracture, Ti-base decementation, and overall prosthetic loosening were the prosthetic complications included in the trial. RESULTS: At the end of the study, a total of 19 patients adhered to the trial. Throughout the exposure process of implants, two implants failed in one patient from the Ti-base group. This patient was excluded from the study on his request. There was no statistically significant difference present between Ti-base and multiunit abutment groups in terms of abutment and prosthetic screw loosening, abutment and prosthetic screw fracture, veneer and framework fracture, Ti-base decementation, and overall prosthesis loosening for 6 and 12 months. Data were explored for normality using Kolmogorov–Smirnov and Shapiro–Wilk tests, data showed non-parametric (not-normal) distribution. Qualitative data were presented as frequencies and percentages. Wilcoxon and Mann–Whitney tests were used to compare the qualitative outcomes in this study. CONCLUSION: Both multiunit and Ti-base are considered a viable line of treatment to construct a screw-retained full arch implant-supported prosthesis.

Full textAbstract:
Purpose: To describe a technique intended to transfer of the intermaxillary and occlusal relationships in a fully digital environment from a complete denture to an implant-supported 3D-printed hybrid prosthesis (an acrylic resin complete fixed dental prosthesis supported by implants). Methods: In edentulous cases, the physiological mandibular position should be determined before the immediate loading procedures. In some cases, the use of interim removable prostheses for a few weeks could be useful to test the new occlusion in centric relation and to verify the prosthetic project. When the correct intermaxillary relationships are achieved, it is difficult to transfer them from the provisional to the final prostheses, as impressions or scans of edentulous arches do not have reference points for intermaxillary records. This paper presents a complex case and the technique used to transfer information from a complete denture to an implant-supported prosthesis with a digital workflow. A prosthetic stent has been used to scan the edentulous mandibular arch and to record the intermaxillary relation. Results: The delivery of the hybrid implant-supported prostheses was carried out with no problems and minimal occlusal adjustments. The patient was extremely satisfied with the treatment and the situation remained stable at the 1-year follow up. Conclusions: The approach described in the present article predictably maintains prosthetic information and allows the delivery of a final implant-supported restoration with the same occlusal relationship as the one tested with the provisional diagnostic dentures.

Full textAbstract:
Accidental ingestion of dental prostheses requires immediate emergency action. The authors report a case of accidental ingestion of a dental prosthesis in a patient with a disorder of consciousness. The accidental ingestion was diagnosed by imaging examination, and the location of the dental prosthesis was explored under general anesthesia according to the preoperative examination images. However, no dental prosthesis was found in the hypopharyngeal region. The operators found a radiopaque region in the nasopharynx that was suspicious of a dental prosthesis by X-ray examination of the head and neck region. According to the X-ray examination, the dental prosthesis was removed from the nasopharynx. The patient’s postoperative course was uneventful. Postural change for cases of accidental ingestion of dental prostheses may be a simple and important lifesaving step in addition to traditional methods.

Full textAbstract:
Prosthetic rehabilitation of an edentulous cleft lip and palate patient with a combined hard and soft palate defect is a great challenge, due to the lack of retention of the obturator prosthesis as a result of its weight and the inability to obtain a border seal. Dental implants improve the retention, stability, and occlusal function of prostheses when used in carefully selected cleft lip and palate cases. This clinical report presents an edentulous unilateral cleft lip and palate patient who has hard and soft palate defects and an atrophied maxilla, treated with an implant-supported speech-aid prosthesis.

Background: Traumatic amputation of fingers results in a serious impairment of hand function and affects the psychological status of the patients. The implant-retained finger prostheses are an alternative treatment. The aim of this case report is to represent the use of osseointegrated implants for retention of finger prostheses in a patient with amputated thumb and index finger. Case Description and Methods: Dental implants were placed in the residual bone of the fingers using two-stage surgery. Custom-made attachments were used to provide retention between implants and silicone prostheses. Prosthetic fingernails were made of composite resin material. Findings and Outcomes: After 6 months, implants were clinically successful, and the patient was satisfied with the appearance and the function of the prostheses. The complications of broken prosthetic nail and mild discoloration were observed. Conclusion: Reconstruction of amputated fingers with implant-retained prosthesis is a worthwhile treatment providing esthetic, functional, and psychological benefits, although some complications might be experienced. Clinical relevance Implant-retained finger prostheses are an acceptable treatment modality for patients with amputated fingers. Evaluating implant prognosis, functional results and prosthetic results of the patients are necessary to address the benefits and complications of the treatment.

This retrospective clinical study was conducted to evaluate the clinical usefulness of a freely removable microlocking implant prosthesis (MLP) that was developed to overcome the problems with conventional implant prostheses. A total of 54 patients (male: 31, female: 23) and 100 implant prostheses were included. Patients were divided into three groups such as 6-12 months, 12-18 months, and 18-24 months according to the used period after implant prosthesis delivery, and the patients in each group were recalled for examinations of survival rate, marginal bone resorption, peri-implant soft tissue indices, and complications. The prosthetic complications were analysed by combining the recorded chart data during the periodic checks including the last call for this study. During a 2-year observation period, all the implants showed a 100% survival rate without clinical mobility and functional problems. There was no significant difference in marginal bone resorption, plaque index, and bleeding index over the observation period after implant prosthesis delivery. Probing depth of the 18-24 months group ( 1.5 ± 0.19 mm ) was significantly lower than that of the 6-12 months group ( p < 0.05 ). The main complication was abutment loosening (4%), followed by implant prosthesis fracture (2%) and food impaction (2%) which were recorded. Within the limits of the present study, the implant prostheses with MLP are considered to be an applicable and predictable treatment method.

Prosthodontic rehabilitation can be accomplished with fixed, overdenture, complete, or implant-retained prostheses. Dental treatment overcomes the patient’s functional, psychological, esthetic and phonation problems. Remaining healthy teeth may allow the dentist to fabrícate a removable partial overdenture, fixed partial prosthesis or implant - supported prosthesis. The retention of a number of abutments helps maintain a positive ridge form with greater height and volume of the alveolar bone, improving masticatory performance, as well as providing a more stable prostheses. Dental patients who have medical problems need many treatment procedures. Multidisciplinary treatment planning is invaluable for patient’s dental health. Progeria is a rare genetic condition where symptoms resembling aspects of aging are manifested at an early age. characteristic clinical findings of Progeria disease include abnormalities of the skin and hair in conjunction with char-acteristic facial features and skeletal abnormalities. The characteristic facies show protruding ears, beaked nose, thin lips with centrofacial cyanosis, prominent eyes, frontal and parietal bossing with pseudohydrocephaly, midface hypoplasia with micrognathia and large anterior fontanel. The other reported anomalies are dystrophic nails, hypertrophic scars and hypoplastic nipples. The findings that are nearly interested in dentistry are delayed dentition, anodontia, hypodontia, or crowding of teeth. This article presents the multidisciplinary dental treatment planning includes surgical, endodontic and prosthetic treatment of a patient with a history of progeria. In this case complete-arch fixed prostheses in both maxilla and mandible, supported by a combination of im-plants and teeth are reported.

Full textAbstract:
Prosthetic treatment of chronic periodontitis often includes making the fixed prosthesis. Its quality links to the simultaneous restoration of lost functions, creation of aesthetics, its mechanical strength and hygienic possibilities. However, sometimes in an attempt to achieve the maximum aesthetic effect and excellent resistance of prostheses, the hygienic possibilities can be ignored. Considering the aetiology of periodontal disease and the influence of local risk factors, we can note that in restoring the integrity of the dental arch, the health of periodontal tissue that often suffers during and due to orthopaedic procedures have to be taken as a priority. The long-term prognosis of a prosthesis, namely of the fixed prosthesis will depend largely on the symbiotic relationship that it will establish with the marginal periodontium.

BACKGROUND: Simultaneous multiple loss of teeth significantly increases the need for immediate orthopedic treatment in dental patients, often with the use of removable immediate dentures due to general somatic pathologies and local Dental Prostheses System features.
AIM: The study aimed to optimize the orthopedic treatment protocol for patients after multiple teeth extractions.
MATERIAL AND METHODS: As part of the study, the orthopedic preparation of 18 patients was conducted for further permanent prosthetics. Patients underwent tooth extraction in the upper or lower jaw amounting to the formation of included, combined, or terminal dentition defects. The following were used for patient treatment: a standard protocol for immediate prosthetics, a modified protocol, including an improved method of vital mucous membrane staining of the prosthetic bed in the surgical intervention area using standard and immediate original design prostheses. The treatment option effectiveness was evaluated based on the results of diagnostic monitoring of wound healing zones in the prosthetic bed area of immediate prostheses, including visual-palpation assessment, vital oral mucosa staining with an iodine-containing diagnostic solution to control inflammation, and a modified Doppler observation method.
RESULTS: Study results revealed that all patients, who used standard immediate prostheses without considering the diagnostic control of inflammation areas, had objective signs of inflammation up to the 20th day of treatment with low microcirculation dynamics in the wound healing area. In 4 out of 6 patients using standard immediate prostheses, considering inflammation control, the vital staining indicators by day 20 indicated a possible trend toward chronic inflammation development in the prosthetic bed area, which was confirmed by an unstable microcirculation picture. The severity of inflammatory changes was insignificant in patients who received the original design of the immediate prosthesis, starting from the 7th day of observation and minimal by the 20th day. At this time the hemodynamics are physiologically normal.
CONCLUSIONS: Based on the study results, the orthopedic rehabilitation protocols effectiveness, with the use of a modified design based on the immediate prosthesis and permanent diagnostic, mucous membrane staining of the prosthetic bed was established to detect inflammatory complications in the wound healing areas.

The current study aimed to evaluate the mechanical behavior of two different maxillary prosthetic rehabilitations according to the framework design using the Finite Element Analysis. An implant-supported full-arch fixed dental prosthesis was developed using a modeling software. Two conditions were modeled: a conventional casted framework and an experimental prosthesis with customized milled framework. The geometries of bone, prostheses, implants and abutments were modeled. The mechanical properties and friction coefficient for each isotropic and homogeneous material were simulated. A load of 100 N load was applied on the external surface of the prosthesis at 30° and the results were analyzed in terms of von Mises stress, microstrains and displacements. In the experimental design, a decrease of prosthesis displacement, bone strain and stresses in the metallic structures was observed, except for the abutment screw that showed a stress increase of 19.01%. The conventional design exhibited the highest stress values located on the prosthesis framework (29.65 MPa) between the anterior implants, in comparison with the experimental design (13.27 MPa in the same region). An alternative design of a stronger framework with lower stress concentration was reported. The current study represents an important step in the design and analysis of implant-supported full-arch fixed dental prosthesis with limited occlusal vertical dimension.

Objectives. To describe dental prosthesis provision in the Brazilian public health service and report the performance of dental prosthesis procedures according to the Brazilian macroregions. Methods. A structured interview was conducted with senior-level health professionals from each of the 18,114 oral health teams (OHT). The dependent variables were performance of removable prostheses and prosthesis procedures, including provision of fixed prostheses by OHT. Descriptive statistics were produced together with performing a cluster analysis using SPSS version 19.0. Results. The manufacture of any type of prosthesis was done by a minority of OHT (43%). The most commonly provided types of dental prosthesis were removable full and partial dentures. Cluster 1 (teams that performed prosthesis procedures the most) was composed of a smaller number of teams (n = 5,531), and Cluster 2 (composed of teams that do not perform prosthetics or that perform them in small amounts) consisted of 12,583 teams. The geographic distribution of clusters reveals that the largest proportion of Cluster 1 teams is located in the Northeast (33.9%) and Southeast (33.6%). Conclusions. A minority of OHT produce dental prostheses. There is an unequal geographical distribution of clusters.

Our purpose was to evaluate the occurrence of complications and the degree of bone loss in a cohort of patients treated with fixed prostheses supported by immediately loaded dental implants. The primary aim was to compare partial versus full-arch fixed dental prostheses. We then tested the effect of sinus lifting. In the present retrospective cohort study, the patients had their implants restored with fixed dental prostheses supported by dental implants positioned in the posterior maxilla and mandible. When necessary, the maxillary sinuses were grafted with particulate autogenous bone. Patients were then ranked according to the following predictors: length of prosthesis, crown-to-implant ratio, number of crowns to number of implants ratio, and presence of sinus lifting. Outcomes were evaluated for up to 2 years regarding the peri-implant marginal bone loss and implant/prosthesis survival rates. Fifty-eight subjects (209 implants) were rehabilitated with 25 fixed full-arch prostheses and 33 partial fixed dental implant bridges (16 supported by implants placed in grafted sinus). The mean marginal bone loss for implants supporting partial fixed dental prostheses amounted to 0.81 mm, whereas that for implants within the group of full-arch fixed dental prostheses was 1.21 mm; the comparison of the levels in the 2 groups showed a significant difference (P = .0055). A statistically significant difference (P = .0006) was found between the bone loss around maxillary implants (1.53 mm) and the bone loss around mandibular implants (1.10 mm). Two implants and 4 prostheses failed; 2-year survival rates of partial and of full-arch fixed dental prostheses, respectively, were 94.1% and 96%. Bone loss in full-arch prostheses appeared to be higher than in that of partial prosthesis. Implant-supported prostheses in the maxillae exhibited a bone loss higher than that registered in mandibles.

Full textAbstract:
In spite of the recent efforts concerning prevention and treatment of dental diseases, total edentulism remains an important world health problem, even in industrialized countries. Different solutions to mandibular total edentulism are available from the classical removable denture to the implant supported prostheses. The aim of the present work is to compare, through finite element simulations, two distinct types of prosthetic solutions. The first one is an implant-supported prosthesis (ISP) using a “All-On-Four” base and the second one is a mandibular implant-retained overdenture (IRO) using two implants. A foodstuff situated on molar is modelled to simulate the mastication force. An orthotropic behaviour is assumed inside the symphyseal area. The results of the simulations show a strong influence of the prosthetic solution type on the stress and strain repartition in the implant and peri-implant bone. This can be explained by the difference of load transfer to bone between those two configurations. Indeed, in the implant-supported prosthesis, the totality of the mastication force is directly transmitted to peri-implant bone whereas the implant-retained solution benefits from a large participation of mucosa to the global load transfer from overdenture to bone.

The aim of this paper is to report a clinical case with bilateral missing mandibular second premolars that were restored by metal-ceramic inlay-retained fixed dental prostheses. The first prosthesis was of a traditional design and the second was of a modified design. The suggested design is created by modifying the retainer wings of the traditional resin-bonded inlay-retained fixed dental prosthesis and covering the wings with composite resin. The modified design is relatively conservative, esthetic and provides an extra element for the retention of posterior metal-ceramic inlay-retained fixed dental prostheses.

INTRODUCTION: The difficulty in accessing oral health services and the practice of dental mutilation has led to a high number of individuals affected by edentulism. In order to reverse this situation, the National Oral Health Policy was implemented and with it the Dental Prosthesis Laboratories. OBJECTIVE: To evaluate the productivity of the dental prothesis of these laboratories in the state of Bahia, in 2016. METHODOLOGY: This was a quantitative-descriptive study in which data were collected from Outpatient Information System of the Unified Health System regarding dental prosthesis productivity. The information of physical structure, human resources of the laboratories and their distribution by health regions were collected in the site of the National Registry of Health and other information about the municipality in the Brazilian Institute of Geography and Statistics. The absolute and relative frequency of the variables and the comparison of productivity with the structural characteristics of the laboratories and health regions of Bahia were presented. RESULTS: We analyzed 51 municipalities that offer dental prosthesis services in SUS, of these 32 have CEO. A total of 46,870 prostheses produced of the type dentures, partial removable, fixed and on implant were observed, with the cities with CEO producing 66.49% and the 19 cities without CEO produced 33.51%. The type of prosthesis most performed was the total (58.73%) followed by the removable partial prosthesis (40.07%). The South region presented the highest productivity of dental prostheses (24.26%) while the region Center North produced the lowest amount (2.28%). CONCLUSION: Although there is a considerable amount of prostheses produced, only 12.2% of the municipalities in Bahia have a dental prosthesis laboratory, even demonstrating a considerable amount of productivity.

Full textAbstract:
Background: The difficulty of frail, non-self-sufficient or non-ambulatory collaborating elderly residents in nursing homes to eat due to a lack of teeth or the absence of a dental prosthesis leads to an increasingly evident increase in the patients’ systemic pathological state, particularly in older patients who take a lot of medications. Total or partial edentulousness that is not filled with dental prostheses or that is filled with inadequate prostheses, associated with socioeconomic factors, depression, impaired motor functions, heart disease and a large number of chronic diseases including excessive use of drugs, often affects elderlies’ feeding. Aim: In this study, prosthetic rehabilitation was performed on some frail elderly residents in 10 nursing homes in the Lombardy district, and, subsequently, meal behavior and social activity were examined in two information questionnaires through compilation. Methods: The research was conducted on only 67 patients, 26 men and 41 women, aged between 75 and 99, who were guests in 10 health facilities (nursing homes) in the Lombard district; only 8 residents did not undergo prosthetic rehabilitation, as they did not cooperate. All the patients who were visited underwent oral prosthetic rehabilitation, and, subsequently, some aspects such as nutrition and socialization were assessed with other residents through the aid of two information dossiers. Results: the results showed that all the residents, despite difficulties in chewing with the new prosthesis, were fed and did not refuse more consistent foods; in addition, there was an improvement in social activity among the residents. Only 19.3% of men and 22% of women continued to eat little; there was an improvement in the participation in social activities among the residents, with a percentage of 73% of men and 88% of women; in particular, during meals 35 residents conversed with the other residents. Discussion: The dental problems of elderly people residing in social welfare homes are increasingly evident when other systemic pathologies are present. It would be desirable to introduce telemedicine in residences for the elderly for the monitoring of dental problems. Conclusions: From the information obtained and from the evaluation of the change in the elderly, it can be concluded that it would be desirable to include specific dental protocols to create a network, including a telematic one, to monitor and perform more dental checks in nursing homes.

OBJECTIVE: The aim of this study was to gather information and discuss the predictability of implant-supported prostheses in patients with bruxism by performing a literature review. METHODS: In order to select the studies included in this review, a detailed search was performed in PubMed and Medline databases, using the following key words: bruxism, dental implants, implant supported prosthesis, and dental restoration failure. Items that were included are: case reports, randomized controlled trials, in vitro studies, literature and systematic reviews, with or without meta-analysis, of the last 20 years that addressed the theme. Articles without abstracts, animal studies, articles in languages other than English and articles from journals unrelated to the dental field were excluded. RESULTS: after analysis according to inclusion and exclusion criteria, 28 articles were selected from a total of 54. It is known from the array of scientific articles which have assessed, either through retrospective, prospective or experimental studies, that the biomechanical and biological impact of bruxism on implant-supported prostheses is small, and that the literature has contributed little to exemplify the prosthetic limits of safety for the specialist from a clinical point of view. CONCLUSION: Although there is still no general consensus on this matter, most of the literature review articles do provide clinical guidelines that contribute to implant supported prostheses longevity and stability in patients with bruxism.

Full textAbstract:
The clinical functionality of the prosthesis structure consists of creating the most convenient conditions without any traumatic effects of chewing forces on the substrate and adapting it to the individual biomechanical exclusions of the stomatognathic system (SS). When transferring functional loads, the optimization of tribological features and the ability to absorb energy is an important design and material parameter. The aim is to evaluate acrylic plastics intended for prostheses in terms of resistance to wear and resistance to movement in sliding contact within the environment of artificial saliva and their ability to absorb energy. Based on the analysis of the test results, it can be pointed out that Vertex is a good material for partial and complete dentures. Villacryl demonstrated similar properties, with Probase and Probase O being slightly worse. The appropriate mechanical parameters of the materials used in the prosthesis allow the production of thin plates that accurately reproduce the prosthetic substrate and improve the patient’s comfort of use through such a fit.

This study aimed to investigate factors associated with dental prosthesis procedures by oral health teams (OHTs) in the Brazilian primary health care in 2013–2014, who participated in the National Program for Improving Access and Quality of Primary Health Care (PMAQ-AB). This is an analytical cross-sectional study using a questionnaire with dichotomous questions applied in 18,114 OHTs. The dependent variable studied was making any type of prosthesis (removable or fixed). Independent variables involved issues related to human resources and health service management. Data were submitted to simple and multiple binary logistic regression with odds ratio calculation, 95% confidence intervals, and p-values. Most OHTs (57%) do not perform any dental prosthesis. The teams that are more likely to perform dental prostheses have human resources-related characteristics, such as professionals admitted through public examinations (OR 1.25, 95% CI 1.14–1.36) and those involved in permanent education (OR 1.13, 95% CI 1.02–1.26). Moreover, OHTs with a more organized work process and that receive more significant support from municipal management are more likely to perform dental prostheses (p < 0.05). The oral health teams which tended to provide the most dental prostheses to benefit patients were; hired as civil servants, had a municipal career plan, involved all members of the oral health team, and trained undergraduate dental students from outreach programs. Better organizational support and improved work incentives may be needed to get the majority of oral health teams to start providing dental prostheses to their patients.

ABSTRACT Background Obstructive sleep apnea (OSA) is one of the common prevalent conditions present worldwide. The process of abnormal habits related to clenching and grinding of teeth is referred to as bruxism and is characterized under the heading of parafunctional activity of the masticatory system. Osseointegrated dental implants represent advancements in the field of odontology. Despite its high success rate, failure and complications are often associated with dental implant treatment due to a number of factors. Hence, we aimed for the present study to assess the incidence of prosthetic complications in patients rehabilitated with implant-borne prosthesis in a sleep disorder unit. Materials and methods The present study included the assessment of all the patients who underwent prosthetic rehabilitation by dental implants. An experienced registered prosthodontist was given duty for examination of all the cases from the record file data. Prosthetic complications in the patients were identified using photographs, radiographs, and all other relevant data of the patients obtained from the record files. All types of complications and other factors were recorded separately and analyzed. Results While correlating the prosthetic complications in OSA patients grouped based on number of dental implants, nonsignificant results were obtained. Significant correlation was observed while comparing the prosthetic complications divided based on type of prosthesis. Fracture of the porcelain was observed in four and eight cases respectively, of screwed and cemented dental implant cases. Conclusion Some amount of significant correlation existed between the incidences of prosthetic complications and OSA. Clinical significance Proper history of the patients undergoing dental implant procedures should be taken to avoid failure.

ABSTRACT Surgical treatment for palate cancers can result in oral-nasal/sinus communication, which impairs the swallowing, speech and chewing ability of patients with reflux of ingested food into the nasal cavity, reducing their quality of life. This article aims to report how three cancer patients, with different types of palate cancer undergoing partial maxillectomy with oroantral or oral-nasal communication as postoperative sequelae were prosthetically rehabilitated from 2009 to 2015. The prostheses were made by dental-surgeons interns in the service of the Multidisciplinary Residency in Oncological Healthcare of the Hospital School of the Federal University of Pelotas (HE/UFPel). One of the patients is completely edentulous, the second partially toothed and in the third case the patient is totally toothed, only requiring the obturator. The creation of prosthetic rehabilitation followed the steps of conventional prostheses, especially observing the particularities in the planning, molding, installation and adjustment stages of the prosthesis. In all cases there was improvement on speech immediately after the prosthesis installation and patients reported greater ease to feed.

This cross-sectional study aims to describe the primary dental care procedures performed by Oral Health Teams (OHTs), adhering to the third cycle of the "National Program for Improving Access and Quality of Primary Care" (PMAQ-AB) in Brazil. A descriptive analysis was performed through 26 dental procedures, including spontaneous, preventive, restorative/prosthetic and surgical procedures, and actions of cancer monitoring. Each conducted procedure assigned a score to the OHT, the final score being the sum of the number of procedures performed by the OHTs. These scores were then compared among the geographic regions of the country. Most OHTs perform basic dental procedures, such as supragingival scaling, root planning and coronal polishing (98.1%), composite filling (99.0%), and permanent tooth extraction (98.6%). The frequency related to dental prosthesis and monitoring of oral cancer decreased. Only 12.9% of the OHTs carries out biopsies, 30.9% monitor patients undergoing biopsy, 15.1% carry out impression for prostheses, and 13.6% carry out prostheses’ installation. The scores reveal that OHT’s performed, on average, 19.45 (±3.16) dental procedures. The OHTs in the South, Southeast, and Northeast had a higher number of primary dental procedures, while the teams in the North and Midwest performed, on average, fewer procedures. The Brazilian regions with the highest dental need have the lowest number of dental procedures. It is necessary to increase the range of procedures offered by OHT and reduce regional inequalities, adapting to the needs of the population in order to achieve comprehensive oral health.

Full textAbstract:
Introduction: The concept of body posture involves balance, neuromuscular coordination and adaptation. Automatic postural responses are adjusted to meet the needs of interaction between systems of postural organization and the environment. Postural control is to maintain body position seeking stability and orientation in space, and the maintenance of posture and balance is directly related to three main systems: visual, vestibular and proprioceptive, whose junction ensures body balance. Other factors may be related to this control, such as the use of prostheses, among them the dentures that provide the balance of the mouth and jaws, through neuromuscular balance, helping to balance the body as a whole. Stabilometry assesses postural balance through the quantification of postural sway in the orthostatic position on a force platform. Objective: To evaluate the influence of the use of dental prostheses in maintaining balance and posture through baropodometry. Method: The study included 10 women with an average age of 65 years old, all using dental prosthesis, which remained on the platform for 30 seconds, with the prosthesis, repeating the procedure without the use of the prosthesis. Results: As the postural balance is given by the sum of the balance of all body structures, where all must be wholesome, and may include dental arch, in this case replaced by dental prosthesis, there was a direct contribution of using it over body balance as a whole, since there was a decrease in the number of oscillations of the body centroid and radial displacement, among individuals who use dental prosthesis. Conclusion: The present study demonstrated that there is a direct influence of the use of dental prostheses on posture and body balance.

The long-term success of dental implants is greatly influenced by the use of appropriate materials while applying the “All-on-4” concept in the edentulous jaw. This study aims to evaluate the stress distribution in the “All-on-4” prosthesis across different material combinations using three-dimensional finite element analysis (FEA) and to evaluate which opposing arch material has destructive effects on which prosthetic material while offering certain recommendations to clinicians accordingly. Acrylic and ceramic-based hybrid prosthesis have been modelled on a rehabilitated maxilla using the “All-on-4” protocol. Using different materials and different supports in the opposing arch (natural tooth, and implant/ceramic, and acrylic), a multi-vectorial load has been applied. To measure stresses in bone, maximum and minimum principal stress values were calculated, while Von Mises stress values were obtained for prosthetic materials. Within a single group, the use of an acrylic implant-supported prosthesis as an antagonist to a full arch implant-supported prosthesis yielded lower maximum (Pmax) and minimum (Pmin) principal stresses in cortical bone. Between different groups, maxillary prosthesis with polyetheretherketone as framework material showed the lowest stress values among other maxillary prostheses. The use of rigid materials with higher moduli of elasticity may transfer higher stresses to the peri implant bone. Thus, the use of more flexible materials such as acrylic and polyetheretherketone could result in lower stresses, especially upon atrophic bones.

Subject. The article provides an analysis of the indicators of life quality of patients after prosthetic treatment. The study included patients with overlapping prostheses based on dental implants and tooth roots. Patients were divided into main and control groups.
Aim – to analyze the quality of life of patients after prosthetic treatment using overlapping prostheses.
Methodology. We conducted prosthetic treatment of 45 patients among them, 19 men and 26 women, aged from 45 to 72 years. Overlapping prostheses based on dental implants were made for patients of the main group. Overlapping prostheses based on the restored tooth roots were made for patients of the control group. We analyzed the quality of life of patients of the main and control groups after prosthetic treatment based on the results of survey. The OHIP-14 method for determining the quality of life in dental patients was used.
Results. After prosthetic treatment of patients of the main group using overlapping dentures based on dental implants, the results of study of life quality were 17.1 ± 2.7. One month after prosthetic treatment, patients in the control group, according to the results of the questionnaire, had quality of life indicators of 18.1 ± 3.9. Orthopedic treatment of patients using overdentures is a modern and effective method. The use of dental implantation in the patients of the main group and the restoration of the roots of the teeth in the patients of the control group to support the overdentures made it possible to achieve optimal results.
Conclusions. The use of overlapping dentures based on dental implants and restored tooth roots improves the quality of life of patients.

Full textAbstract:
The poor positioning of dental implants directly influences the functional and esthetic result of the implant-supported prosthesis. And as an alternative to correcting the positioning, prosthetic components such as prefabricated and customized abutments may be used. The current study aims to present an alternative resolution for malpositioned dental implants, with the hopes of minimizing damage to osseointegration and gingival tissues. A 53-year-old female patient had two implants in regions 11 and 21 with a height discrepancy of approximately 7 mm between them. The following treatment plan was proposed: the manufacture of two metal-free crowns and the use of a customized abutment to correct the height of the implant. A metal UCLA (Universal Long Castable Abutment) was used as a healer. The case includes 5 years of follow-up. It can be concluded that the use of a customized abutment as a prosthetic solution for an implant installed far below the cervical region of the tooth presented satisfactory esthetic and functional results with peri-implant bone maintenance and long-term gingival health.Descriptors: Dental Implantation; Dental Prosthesis, Esthetics, Dental.ReferênciasGoodacre CJ, Bernal G, Rungcharassaeng K, Kan JY.

Abstract Introduction The use of osseointegrated dental implants for the rehabilitation of patients has revolutionized dentistry. Objective To retrospectively evaluate the survival rate and the frequency of complications with external hexagon platform supporting single crowns. Material and method Dental forms of 110 patients who received 143 implants at the Ilapeo College (2004-2015) were used. The variables were: age, gender, systemic involvement at the time of surgery, region, implant design, type of surface, fixation system, pillar type and prosthesis material. The outcome variables were the incidence of complications in the implant or prosthesis and time in use. The mean follow-up period was 9 years. Result 32.8% had some systemic disease. Ninety-six implants (67.1%) were installed in the maxilla and 47 (32.9%) in the mandible, 87 (60.8%) were in the posterior region and 56 (39.2%) in the anterior region, while 40 (28%) were placed in regions that had received bone reconstruction. The majority (97.2%) of the implants presented surface treatment, 42% had a cylindrical design and 58% were tapered. The majority of the prosthetic components (89.6%) used were UCLAs and most of the prostheses were fused-to-metal (79.7%). The rate of prosthetic complications was 19.58% and three implants had been lost (97.9% survival rate). There was no statistical difference between the variables analyzed for both the occurrence of prosthetic complications and for the loss of the implant. Conclusion Implants with external hexagon connection were an effective and predictable option to support crowns and had high survival rates.

Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal implants. In each group we distinguish two subgroups according to the type of prosthetic restoration: single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss, parallelized periapical radiographs were analyzed at the time of implant placement and after two years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants regardless of the type of prosthesis.

Full textAbstract:
Objective This case report describes the clinical and surgical management of a patient with a unilateral alveolar cleft and associated extremely atrophied totally edentulous maxilla. Method Two zygomatic implants and four endosseous oral implants were placed under general anesthesia in a compromised maxilla to rehabilitate a 33-year-old patient with cleft lip and palate. The two specially designed zygomatic implants were utilized to avoid the need for bone grafting in the patient. The final prosthetic rehabilitation was an esthetic and functional maxillary overdenture prosthesis supported by implants. Results Preliminary results have shown how dental prostheses supported by endosseous implants in grafted alveolar cleft are a reliable possibility in the dental rehabilitation of this malformation. Conclusion The use of zygomatic implants may be considered a reliable alternative to more resource-demanding techniques such as bone grafting in patients with cleft palate.

Full textAbstract:
BACKGROUND: Optimized use of removable dental prosthesis and enhancement of the adaptation period to such orthopedic substituting dental constructions in the oral cavity are the actual aims of practical stomatology.
AIM: This study aimed to estimate the psychological state of patients in the process of adaptation to removable dental prostheses and to assess the influence of dental prosthesis fixation on the optimization of adaptation for them.
MATERIALS AND METHODS: In the case of psychosensoryanatomicalfunctional maladaptation syndrome, the psychological states of 35 people with partial and 38 with complete tooth loss before and during the adaptation period of their dental rehabilitation for removable acrylic dentures were assessed. The study groups were divided into two subgroups, depending on the method used to improve the fixation of dentures.
RESULTS: During the initial examination, all study patients with partial or complete tooth loss had impaired adaptability to these conditions, mainly due to anatomical and functional disorders of the masticatory apparatus. During the adaptation period, an improvement in the psychological status of the patients was noted, especially in those who used the cream for fixation of dentures for domestic production.
CONCLUSION: During their adaptation to the removable partial and full dentures, patients are recommended to use the prescribed cream to improve their fixation and thereby allow the reduction of painful symptoms from the prosthetic bed tissues and significantly improve the psychological status of the patients during the adaptation period.

Full textAbstract:
The aim of the study was to conduct a comparative assessment of the time spent by an orthopedic dentist and a dental technician for manufacturing the frames of arch prostheses obtained using digital and traditional technologies. The patients were divided into two groups. The first group consisted of 10 patients (4 men and 6 women), whose orthopedic treatment was performed with arch prostheses made according to the traditional method. Patients in the second group (7 men and 3 women) were treated using additive manufacturing technology. In total, 20 frames of arch prostheses were made, 10 in each group. The Mann-Whitney U-test was used for statistical analysis of the results obtained. Based on the data obtained, it was found that for the manufacture of an arc prosthesis frame using the Asiga Max UV 3D printer, an orthopedic dentist needs to spend 40.9±5.322 minutes, and a dental technician — 177.2±9.259 minutes. To make the frame of an arc prosthesis using traditional casting technology, the orthopedic dentist must spend 41.1±5.322 minutes, and the dental technician — 240.3±8.895 minutes. These data allowed us to conclude that the production of the arch prosthesis frame using modern digital technologies requires less total time and time spent by a dental technician in the laboratory, compared to the traditional casting method (p<0,0166667). No statistical differences were found between the time spent by the orthopedic dentist in the clinic when manufacturing the arch prosthesis frame using digital and traditional methods.

Aim: To investigate the relationship between oral candidiasis and users of dental prostheses. Methods: A cross-sectional study was carried out which the inclusion of adults and elderly people of both genders using dental prostheses. Lectures were given with guidelines on oral hygiene techniques and dental prostheses, preventive measures of candidiasis, highlighting their influence on the oral and general health of the individual for the 240 users of dental prostheses. Of this number, 153 did not want to participate in the clinical examination. Signals and symptoms were analyzed in 87 patients, and lesions were present in only 21, and a cytological complement of the lesions was performed. Data were analyzed using SPSS version 15.0 with Chi-square (χ2 ) test at p < 0.05. Results: The 21 patients presented oral candidiasis, with erythematous (prosthetic) stomatitis being the most prevalent. There was a correlation between the presence of Candida and the use of prostheses (p- value 0.00*). Candidiasis was associated with poorly adapted prostheses, poor oral hygiene, inadequate prostheses and prolonged use of them. Conclusion: There was a correlation between oral candidiasis and users of dental prostheses. The most prevalent type of candidiasis was erythematous stomatitis (prosthetic), and nystatin was used to treat all cases. The preventive activities carried out were extremely important, since patients were not aware of oral candidiasis and the factors that trigger it, such as poor oral hygiene and dental prostheses.

We report prosthetic knee arthritis in a 55-year-old diabetic man due to Granulicatella adiacens, a micro-organism present in the oral flora, usually described in endocarditis but rarely in prosthesis joint infection. This patient had undergone a dental extraction without antibiotic prophylaxis one month before, and an aseptic loosening of the prosthesis had been diagnosed previously. If antimicrobial prophylaxis against infective endocarditis for dental procedures is well established, such an approach is still controversial for joint prosthesis and should be considered in some conditions.

Introduction. Success in functional rehabilitation of the craniomandibular system in patients without teeth, which have total prosthesis, can be assessed using different clinical and functional methods. Subjective assessment, motivation, comfort level and functional efficacy are important elements for adaptation to dental prosthesis as well as base for success in prosthetic therapy. The aim of this study was to evaluate the importance of subjective assessment of the mastication in people with new dental prosthesis as well as to assess the value of that parameter in determining the successful prosthetic therapy. Material and Methods. Study was conducted at the Dental Clinic in Novi Sad. Thirty patients (16 males and 14 females) with average age of 62.5 years who received total prosthesis were included. Analysis was done according to the data from the medical records and conducted survey in the form of questionnaire which was adjusted to our clinical examinations. Results. Results showed that 96.6% of the patients were satisfied with new prosthesis. Subjective assessment of the quality of their mastication before therapy showed that 63.4% consider their mastication as unsatisfied, 26.6% satisfied while 10% of toothless patients thought their mastication was good. Statistic analysis showed there was significant difference in subjective assessment before and after the therapy (p<0.01). In fact, there was significant connection between subjective assessment of the mastication and satisfaction with new prosthesis and therapy at all (p<0.01). Conclusion. Patients satisfaction with total prosthesis and subjective assessment of mastication are in direct correlation with successful prosthetic treatment. Results of subjective assessment of the mastication are important and can be used as a parameter for success along with precise survey.

Full textAbstract:
The purpose of the study was to investigate the influence of 3D printing parameters on fit and internal gap of 3D printed resin dental prosthesis. The dental model was simulated and fabricated for three-unit prostheses with two implants. One hundred prostheses were 3D printed with two-layer thicknesses for five build orientations using a resin (NextDent C&B; 3D systems, Soesterberg, The Netherlands) and ten prostheses were manufactured with a milling resin as control. The prostheses were seated and scanned with micro-CT (computerized tomography). Internal gap volume (IGV) was calculated from 3D reconstructed micro-CT data. IGV, marginal fit, and lengths of internal gaps were measured, and the values were analyzed statistically. For the 3D printed prostheses, IGV was smaller at 45°, 60°, and 90° compared to other build orientations. The marginal fit evaluated by absolute marginal discrepancy was smaller than other build orientations at 45° and 60°. IGV was smaller at 50 µm layer thickness than at 100 µm layer thickness, but the marginal fit was smaller at 100 µm layer thickness than at 50 µm layer thickness. The 3D printed prosthesis had smaller internal gap than the milled prosthesis. The marginal fit of the 3D printed resin prosthesis was clinically acceptable, and build orientation of 45° and 60° would be recommended when considering fit and internal gap.

Dental implants, or completely said as dental implant bodies, function as analogues of tooth roots, achieving aunion directly with jawbone following their insertion into a prepared socket in the bone. Implant system have threebasic components, namely the dental implant body that is lying in the jawbone, abutment that lies on the jawboneand the prosthesis. Dental implants may stabilize a removable prosthesis, complete or partial overdentures, and orsupport and stabilize a fixed prosthesis. In designing implant-supported removable prostheses, there are three formsof anchorage frequently used, namely bar/sleeve (clip) joints which links two or more implants, ball/cap anchoragesapplied individually to two or more isolated implants, and magnets/magnetic keepers. Implant-supported fixedprosthesis is either screwed to or cemented on to the abutment.

OBJECTIVE: To conduct a cost-effectiveness analysis of alternatives for rehabilitation treatment of mandibular edentulism in the context of the Brazilian Unified Health System (implantsupported total dental prosthesis versus conventional total dental prosthesis). METHODS: A Markov model was developed to capture long-term clinical and economic outcomes. The model’s population was comprised of a hypothetical cohort of 1,000,000 patients, aged 55 years, with total mandibular edentulism and without medical contraindications for performing surgical procedures. The adopted analysis perspective was that of the Brazilian Unified Health System. Based on the proposed model, we calculated cost – in BRL, and effectiveness – measured by quality-adjusted prosthesis year (QAPY). The time horizon of the analysis was 20 years. RESULTS: Considering a 5% discount in costs and effects, the incremental cost-effectiveness ratio of implant-supported total dental prostheses compared to conventional total dental prosthesis (BRL 464.22/QAPY) was lower than the willingness to pay threshold adopted in the model (BRL 3,050.00/QAPY). CONCLUSIONS: The results of this economic analysis showed that the rehabilitation of mandibular edentulous patients by implant-supported total prosthesis is very cost-effective when compared to conventional complete prosthesis, considering the cost-effectiveness limits employed.

This study aimed to assess the masticatory efficiency in patients with a removable dental prosthesis, presenting different systemic, oral and prosthetic states while chewing different foods. The study was conducted on a convenient sample of patients aged 45 and above, with removable prostheses in at least one jaw. Patients were asked to chew samples of digestive biscuits, apple, and carrot, until the sensation of swallowing. The recorded masticatory function parameters were: chewing time, the number of mastication cycles, mean masticatory cycle duration, and chewing frequency. We found out that the masticatory functional parameters registered statistically significant differences according to the chewed food (e.g., generally the highest values were recorded for carrot and lowest for apple), most likely this being in relation to food’s consistency, wetting, and adherence. High positive correlations were found between the chewing time and the number of mastication cycles for all three foods taken into consideration. Higher values for chewing time and number of mastication cycles were found for all foods in patients with complete dentures and overdentures, and while chewing carrot in patients with altered general status and of advanced age. Therefore, it that it takes a different time and number of mastication cycles to complete chewing, in relation to individual and food characteristics, to the systemic, oral and prosthetic patient’s status. The residual teeth number and the type of prosthetic rehabilitation favor the adaptation and improvement of masticatory parameters and can have marker value for masticatory efficiency.
