Abstract:

The objective of this research was to investigate dental bridges with and without implants. Threedimensional (3D) mandible models were reconstructed by computer tomography (CT) to simulate biting behaviors. The dental implant is an important factor in dental bridge applications. Several studies have investigated finite element models for dental implants; however, few have examined a model for dental bridge with implant. The results revealed that stress was significantly increased when dental bridge was used with implant. Moreover, the dental bridge with implant group demonstrated a relatively big stress in mandible, which was 4.01% lower compared with that of the control group. Dental bridge would be an effective means of recovering dental performance. However, the present research stated that the implant of dental bridge has a potential to increase abnormal stress, and uniformly distributing stress in the dental bridges.

Abstract:

Objectives The aim of this study was to demonstrate the clinical applicability of limited cone beam computed tomography (Dental 3D-CT) for assessment of bone-grafted alveolar cleft. Patients and Methods Seventeen bone bridges were examined after alveolar bone grafting in 13 patients with cleft lip and palate. All bone bridges, including cleft-adjacent teeth, were examined by plain radiography and the Dental 3D-CT imaging system. Results The plain radiographs showed the approximate condition of the bone bridge and cleft-adjacent teeth. The Dental 3D-CT images clearly showed precise three-dimensional (3D) morphology of the bone bridge, 3D relationships between the bone bridge and the roots of cleft-adjacent teeth, and their periodontal condition. In addition, the conditions surrounding dental implants installed in the bone bridge could be observed three-dimensionally. Conclusions The results indicate that the Dental 3D-CT imaging system is suitable for clinical assessment of alveolar bone grafting before and after installation of dental implants or orthodontic treatment of the cleft-adjacent teeth.

Abstract:

Abstract Elderly people suffer from more and more teeth problems. The tooth-implant-supported prosthesis provides a reliable solution to missing teeth patients. The proper dental prosthesis design to prevent overstress is essential due to the mechanical characteristics of the dental bridge abutments are different. The finite element method is widely applied, but proper experimental validation is required. The curing shrinkage epoxy is applied for the photoelasticity measurement because its mechanical property is close to the cancellous bone. A series of process developments, including mold design, residual stress releasing and artificial soft film making, is accomplished in this research to simulate the mechanical response of dental bridges in practice. The process is proven and can be accomplished at the dentist's workshop. The transmission photoelasticity technique is applied to measure the residual stress distribution and it nondestructively provides the continuous improvement guideline. The model-making procedure and tools are proven to be available at the dental workshop. Following the model-making procedure, the dental bridge model shows a low residual stress level that the photoelasticity system cannot detect. Excellent reproducibility of the proposed procedure has been validated. These models exhibit stable maximum stress of 2.13 MPa around the natural tooth apex and apical implant region when a 300 N vertical loading is applied upon the dental bridge. Finally, a finite element model of the dental bridge, including the natural tooth and dental implant, is built and validated by the photoelastic measurement.

Abstract:

The number of supporting dental implants is an important criterion for the surgical outcome of dental bridge fixation, which has considerable impact on biomechanical load transfer characteristics. Excessive stress at the bone–implant interface by masticatory loading may result in implant failure. The aim of this study was to evaluate the impact of the number of implants supporting the dental bridge on stress in neighboring tissues around the implants. Results of the study will provide useful information on appropriate surgical techniques for dental bridge fixation. In this study, osseointegrated smooth cylindrical dental implants of same diameter and length were numerically analyzed, using three-dimensional bone–implant models. The effect of the number of supporting implants on biomechanical stability of dental bridge was examined, using two, three and four supporting implants. All materials were assumed to be linearly elastic and isotropic. Masticatory load was applied in coron-apical direction on the external part of dental bridge. Finite Element (FE) analyses were run to solve for von Mises stress. Maximum von Mises stresses were located in the cervical line of cortical bone around dental implants. Peak von Mises stress values decreased with an increase in the number of implants that support the dental bridge. Results of this study demonstrate the importance of using the correct number of supporting implants to for dental bridge fixation.

Abstract:

FEM studies were made on a zirconia dental bridge of 4 elements with supports on 2.4 and 2.7, and edentation on 2.5 and 2.6. Appling a compressive force of 350N on Z direction, quite normal for mastication, was analyzed the behavior of the dental bridge. Zirconia, although having a high mechanical strength, is fragile when rotation or bending movements occur. The analysis reveals some bridge deficiencies, which may be due either to inaccuracies in the prosthetic abutment construction (especially in relation to their inclination), to the technique of realization or to insufficient dental support. In our study, the most vulnerable elements are the crowns on teeth 2.4 and 2.7. Finite element analysis, highlighting possible structural and design deficiencies, may be a solution to improve dental bridges. The only disadvantage of the finite element analysis that was performed before the actual restoration is related to the fact that performing the simulations involves a time-consuming phase.

Abstract:

The aim of the present research was to evaluate the biomechanics of dental bridge with and without implant. Oral models were reconstructed by 3D computer tomography images to simulate oral environment. The stress is an important role in dental bridge applications for osseointegration. Many studies have investigated finite element researches for dental implants; however, few have evaluated a model for dental bridge with and without implant. The results revealed that abnormal focusing stress was found when dental bridge was used with implant. Moreover, the unbalance situation was found on the model with only one implant, the highest stress appeared in the present group. Dental bridge with implants would be an effective means of recovering dental performance. However, the present study showed that if only one pier with dental implant in bridge treatment has a potential to increase abnormal stress, and uniformly distributing stress.

Abstract:

Inlay-retained dental bridges can be a viable minimally invasive alternative when patients reject the idea of implant therapy or conventional retained full-coverage fixed dental prostheses, which require more tooth preparation. Inlay-retained dental bridges are indicated in patients with good oral hygiene, low susceptibility to caries, and a minimum coronal tooth height of 5 mm. The present study aims to evaluate, through the finite element method (FEM), the stability of these types of dental bridges and the stresses on the supporting teeth, under the action of masticatory forces. The analysis revealed the distribution of the load on the bridge elements and on the retainers, highlighting the areas of maximum pressure. The results of our study demonstrate that the stress determined by the loading force cannot cause damage to the prosthetic device or to abutment teeth. Thus, it can be considered an optimal economical solution for treating class III Kennedy edentation in young patients or as a provisional pre-implant rehabilitation option. However, special attention must be paid to its design, especially in the connection area between the bridge elements, because the connectors and the retainers represent the weakest parts.

Abstract:

Ceramics have rapidly emerged as one of the major dental biomaterials in prosthodontics due to exceptional aesthetics and outstanding biocompatibility. However, a challenging aspect remaining is its higher failure rate due to brittleness, which has to a certain extent prevented the ceramics from fully replacing metals in such major dental restorations as multi-unit bridges. This paper aims at simulating the crack initiation and propagation in dental bridge. Unlike the existing studies with prescriptions of initial cracks, the numerical model presented herein will predict the progressive damage in the bridge structure which precedes crack initiation. This will then be followed by automatic crack insertion and subsequent crack growth within a continuum to discrete framework. It is found that the numerical simulation correlates well to the clinical and laboratory observations.

Abstract:

Purpose This paper aims to develop an additive manufacturing technique for complex zirconia ceramic dental bridges. Design/methodology/approach To carry out this study, a dental bridge model was obtained by three-dimensional reverse engineering, and a light-curable zirconia ceramic suspension was formulated. Zirconia bridges were manufactured by stereolithography and then treated by vacuum freeze drying, vacuum infiltration and sintering. The optimal scanning speed was determined according to the shape precision comparison. Then, characteristics of the sintered ceramic parts were tested as size shrinkage, relative density, surface Vickers hardness, surface roughness and microstructure. Findings The method for preparation of light-curable zirconia suspension (40 volume per cent solid loading) with a viscosity value of 127 mPa·s was proposed. The optimal laser scanning speed for zirconia bridge fabrication was 1200 mm/s. A relative density of 98.58 per cent was achieved; the obtained surface Vickers hardness and surface roughness were 1,398 HV and 2.06 µm, respectively. Originality/value This paper provides a potential technical method for manufacturing complex zirconia dental bridges and other small complex-shaped ceramic components which are difficult to be made by other manufacturing techniques.

Abstract:

Abstract The paper presents example tests of the functional quality of selected designs of dental bridges. These were: porcelain bridges on a metal base (cobalt based alloy), porcelain bridges on a zirconia base (zirconia ceramic – Zirkon Zahn), and full zirconia bridges (Zirkon Zahn). For the purpose of the study, durability of bridges in cyclic fatigue testing was adopted as a measure of their quality. The tests were carried out on a Zwick Roell Z010 universal testing machine. They consisted in cyclic loading and unloading of dental bridges mounted on gypsum models at a loading force of F= 400 [N] and a frequency of load of f= 1 [Hz]. Each bridge was subjected to a cycle of 7200 loads. The results show that there are no significant differences in the functional quality of the bridges.

Abstract:

The aim of the present study is to investigate the comparison between the biomechanical behavior of the dental prosthesis composed of three implants replacing successively the premolar and two molars and the dental bridge located between two implants. Both dental structures were subjected to the same masticatory loading (Corono-apical, Linguo-buccal and Disto- mesial). Three-dimensional finite element models of dental structures were developed to determine the stress distribution under simulated applied loads. In this study the biomechanical behavior of prosthetics dental crowns subjected to static loads in contact with the jawbone has been highlighted. Biomechanical simulations indicated that the equivalent stresses in the dental bridge are greater than that produced in the dental prosthesis. The dental bridge can be assimilated to a beam at the embedded ends, subjected to the bending.

Abstract:

The article presents the study results of clinical effectiveness of orthopedic rehabilitation for patients with dentition defects with different designs of implant-supported dental bridges. The work describes and analyzes complications that occurred during the operation of dental bridges and identifies the optimal design with the most predictable prognosis. The purpose of the study was to evaluate the results of prosthetics in patients with dentition defects with various implant-supported dental bridge designs in different observation terms. Materials and methods. For the clinical investigation we selected 90 patients with dentition free-end defects, who were divided into three groups, 30 patients in each group. Group I patients had dental bridges with cobalt-chromium alloy, faced with feldspar ceramic made, patients of II group – prosthetic constructions on the basis of zirconium dioxide with feldspar ceramic coating, patients of III group – zirconium dioxide framework with following press-ceramic coating. Oral hygiene index OHI-S and Leus comprehensive periodontal index, compliance of the fabricated dental bridges with clinical requirements, and the most common complications that occurred during the use of these fixed prostheses were evaluated for all patients. Results. After 36 months, we found that the highest mean value of OHI-S index was in patients of group I, specifically 1.24±0.19 points. Significantly (p<0.05) lower this index was in patients of group II – 0.64±0.09 points. Minimal OHI-S index was found in group III patients, being at 0.43±0.04 points, it was significantly (p<0.05) different from indicators of group I and group II patients. The mean values of comprehensive periodontal index also differed significantly (p<0.05) in all groups, their indices ranged between 1.24±0.21 points, 0.35±0.03 points and 0.24±0.02 points, respectively. Group II patients' orthopedic constructions turned out to be the most effective, with 96.7% of the prostheses having no malfunctions after 3 years of use. The only violation that occurred in this group was full fracture of intermediate part of one dental bridge. The number of dental bridges that functioned without complications in groups I and III during the same term was 70.0% and 90.0%, respectively. Among the complications, the most frequently observed were chipping of the aesthetic coating of the prosthesis, integrity and retention violations of the dental bridges in different terms. The worst hygienic and comprehensive periodontal indexes were recorded in patients with metal-ceramic dental bridges. Conclusion. The use of zirconium dioxide frameworks and veneered feldspar ceramics provides the most reliable functioning of fixed implant-supported dental bridges and the minimum number of complications in the observation period of 36 months

Abstract:

In order to increase the patient�s quality of life, interdisciplinary studies on dental materials are becoming more and more frequent in an attempt to assess as accurately as possible the resistance of dental restorations over time. One of the methods of analysis of resistance to the masticatory forces of dental restorations is the finite element method (FEM). We studied a 3-element dental bridge made of a metallic Co-Cr-Mo alloy and dental ceramics, designed for the prosthesis of a tooth 3.6. On each element of the dental bridge we applied a force of 250 N in the direction Z and a force of 100 N in the Y direction. The most vulnerable areas, where the highest stresses occur, are located predominantly in the neck regions and around the points of contact between the elements of the dental bridge. However, the experimentally determined values have low intensities that would not endanger the resistance of the restoration unless it is overloaded.

Abstract:

Implant fixed dental prostheses are widely used for the treatment of edentulism, often preferred over the screw-retained ones. However, one of the main features of an implant-supported prosthesis is retrievability, which could be necessary in the case of implant complications. In this study, the retrievability of implant-fixed dental prostheses was investigated considering two of the main factors dental practitioners have to deal with: the abutments geometry and the luting agent. Impulsive forces were applied to dental bridge models to simulate crowns’ retrievability in clinical conditions. The number of impulses and the impulsive force delivered during each test were recorded and used as retrievability indexes. One-hundred-and-five tests were conducted on 21 combinations of bridges and luting agents, and a Kruskal-Wallis test was performed on the results. The abutment geometry significantly influenced the number of impulses needed for retrieval (p < 0.05), and a cement-dependent trend was observed as well. On the other hand, the forces measured during tests showed no clear correlation with bridge retrievability. The best retrievability was obtained with long, slightly tapered abutments and a temporary luting agent.

Abstract:

Dental implantation is a procedure of implanting an implant in the jawbone of the patient with subsequent prosthetics of their crowns, bridge or conditionally removable dentures. The implant is a pre-trained artificial construct that is embedded in the tissue of the jaw for future restorations. Implants are designed to replace the roots of lost teeth, allowing in the future restoring the dentition. The following article explores the process of implantation.

Abstract:

AbstractImplant treatment is a proven method in dentistry for partial and complete missing teeth reconstruction. In some clinical situations it is advisable to limit the number of implants, which can be obtained by making a bridge connecting the patient’s own tooth with the implant. So far, the possibility of using safe and permanent connections of natural teeth with implants has been examined to a small extent due to the dangers resulting from the different mobility of dental implants and teeth.An attempt was made to use vibro-acoustic techniques to evaluate various combinations of teeth and implants. Pilot studies were carried out on cadavers-pig mandibles with implants. There were recorded sounds in the immediate vicinity of the mandible formed in response to impulse excitations carried out with a point hit against a tooth or implant before and after their joining with a bridge. The comparison of spectra allows to see features indicating a high probability of being able to distinguish between the examined configurations.The results of the research should contribute to a better understanding of the mutual relations between the dental implant and the tooth, which are included in bridge. In the perspective, it will enable to assess the level of safety and to identify clinical situations that allow to obtain dental bridges based on teeth and implants.

Abstract:

The anterior single missing tooth is a challenge to the dental surgeon when it comes to functional, aesthetic and biological integration especially when in adolescents or young adults, where passive eruption of the tooth is still active and where implant placement must be postponed. As a temporary or a long-term treatment, a fixed prosthesis can be placed, but in the era of maximum tissue preservation, dental practice is moving towards a harmless and conservative prosthetic therapy “the cantilever bonded bridge”.The indication is limited to the replacement of central or lateral maxillary incisor and mandibular incisors and therefore requires following a precise and rigorous clinical protocol. This article will discuss a simplified clinical realization of the ceramic cantilever bridge.The use of cantilever bonded bridges (single retainer) seems to be an excellent alternative compared to other therapeutic solutions.

Abstract:

Dental pulp vitality is a desideratum for preserving the health and functionality of the tooth. In certain clinical situations that lead to pulp exposure, bioactive agents are used in direct pulp-capping procedures to stimulate the dentin-pulp complex and activate reparative dentinogenesis. Hydraulic calcium-silicate cements, derived from Portland cement, can induce the formation of a new dentin bridge at the interface between the biomaterial and the dental pulp. Odontoblasts are molecularly activated, and, if necessary, undifferentiated stem cells in the dental pulp can differentiate into odontoblasts. An extensive review of literature was conducted on MedLine/PubMed database to evaluate the histological outcomes of direct pulp capping with hydraulic calcium-silicate cements performed on animal models. Overall, irrespective of their physico-chemical properties and the molecular mechanisms involved in pulp healing, the effects of cements on tertiary dentin formation and pulp vitality preservation were positive. Histological examinations showed different degrees of dental pulp inflammatory response and complete/incomplete dentin bridge formation during the pulp healing process at different follow-up periods. Calcium silicate materials have the ability to induce reparative dentinogenesis when applied over exposed pulps, with different behaviors, as related to the animal model used, pulpal inflammatory responses, and quality of dentin bridges.

Purpose: of this paper is to investigate the accuracy of Co-Cr dental bridges, manufactured using 3D printed cast patterns. Design/methodology/approach: Four-unit dental bridges are fabricated from the alloys i-Alloy and Biosil-f by lost-wax process. The polymeric cast patterns are 3D printed with different layer’s thickness (13 μm, 35 μm and 50 μm). Two 3D printers are used: stereolithographic “Rapidshape D30” and ink-jet “Solidscape 66+”. The geometrical and fitting accuracy as well as the surface roughness are investigated. Findings: It is established that Co-Cr bridges, casted from 3D printed patterns with 50 μm layer thickness, characterize with the largest dimensions – 3.30%-9.14% larger than those of the base model. Decreasing the layer thickness leads to dimensional reduction. The dimensions of the bridges, casted on patterns with 13 μm layer thickness, are 0.17%-2.86% smaller compared to the primary model. The average roughness deviation Ra of the surface of Co-Cr bridges, manufactured using 3D printed patterns, is 3-4 times higher in comparison to the bridge-base model. The greater the layer thickness of the patterns, the higher Ra of the bridges. The silicone replica test shows 0.1-0.2 mm irregular gap between the bridge retainers and abutments of the cast patterns and Co-Cr bridges. Research limitations/implications: Highly precise prosthetic constructions, casted from 3D printed patterns, can be produced only if the specific features of the 3D printed objects are taken in consideration. Practical implications: Present research has shown that the lower the thickness of the printed layer of cast patterns, the higher the dimensional accuracy and the lower the surface roughness. Originality/value: The findings in this study will help specialist in dental clinics and laboratories to choose the right equipment and optimal technological regimes for production of cast patterns with high accuracy and low surface roughness for casting of precise dental constructions.

Abstract:

Background: Crowns and multi-unit fixed partial dentures have a limited lifetime. They fail for a number of reasons. The removal of provisional crowns and bridges is generally simple, however for permanent crowns, it becomes more challenging. Careful removal of FPD can help a dentist simplify a resto or endo procedure. The aim of this article was to analyze the different methods available for the removal of crowns and bridges and their awareness among dental practitioners Study Design & location: This was a cross-sectional study based on a questionnaire. The questionnaire was filled by a total of 250 general and specialist dentists who were practicing in various individual and group-based dental practices as well as private and government setups of Islamabad and Rawalpindi. Methodology: The questionnaire comprised a total of 13 questions to find out dentists' views about the usage of different system’s available for dental crowns and FPD removal. Participants were selected by random sampling. The results were then analyzed using SPSS version 23. Frequencies, percentages of different variables used in the study were calculated to identify the co-relation among different attributes. P-value of less than or equal to 0.05 was considered statistically significant. Results: The study reflected that out of those who answered, 247 dental professionals (98.5 %) preferred using hemostats or Morrell sliding hammer or a combination of both as they offered better control of force. A small percentage (approx 2%) of dentists used diamond or carbide burs as their first preference to trim off old crowns. Clinicians rarely used laser due to its high cost and less availability and its effectiveness primarily related to Porcelain jacket/ Zirconium crowns. Conclusion: It was concluded from this study that the majority of dentists preferred Morrell type crown remover with sliding hammer due to its ease of availability, universal acceptance, simple to use and because as it offered better control of force as opposed to spring-lock type Keywords: Crown and bridge removal, Crown and bridge disassembly, Crown and bridge failure.

Abstract:

Veterinary dentistry has tended to follow the trends and advancements in the human dental field. As for any procedure performed on a patient, whether human or animal, an informed decision is based on the available evidence regarding treatment options. This is certainly true for the more involved treatments in veterinary dentistry which can include the disciplines of endodontics and dental implantology. A number of published case reports have been accepted by the specialty that endodontic therapy is indeed a predictable and a valuable service that can be offered to pet owners. Oral implantology has become an accepted and predictable procedure in the human dental field and can now be offered to pet owners if performed by suitable trained veterinary clinicians. The success rate for endosseous implant osseointegration is very high in humans. Success rates are also very high in animals used for implantology research. Canine studies have shown good bone-to-implant contact of around 73% in osseointegrated endosseous implants based on histological sections. Radiographic and histological findings demonstrate stable alveolar crestal bone levels after loading endosseous implants for up to 12 months in a dog model. This article discusses use of dental implants in the rostral mandible of a companion dog to replace periodontally diseased incisors, their restoration, to return the animal to full dental function and 3-year follow-up.

Abstract:

Oral care is easily neglected in patients in an intensive care unit (ICU) because they are often intubated or have altered mental status. Although care workers pay careful attention to the mouth, tooth loss often occurs in the ICU. Here we report 3 cases of dental bridge loss undetected by the ICU staff. One patient was under mechanical ventilation via an endotracheal tube after emergency intubation, whilst 2 patients were drowsy but not intubated. Consecutive chest X-rays revealed dental bridge loss in all 3 cases, but this was not identified immediately. Along with other critical management approaches, these cases demonstrate how an initial evaluation of the oral cavity, with special attention to the number of teeth, and the existence of dental prosthetics is essential to preventing potential deleterious complications. The number of teeth and the existence of dental prosthetics must be documented in ICU patients.

Abstract:

Summary. Having and maintaining a smile aesthetic is an essential component of modern popular culture. Adhesive bridges («Maryland bridge») have been developed to eliminate single included defects in the dentition in the frontal areas, without preparing the supporting teeth. In modern conditions this technology is the method of choice since single defects in the anterior part of the dentition can also be eliminated through orthodontic treatment, manufacturing of a partially removable plate prosthesis, a traditional dental bridges, the manufacturing of cantilever orthopedic structures and prosthetics based on a dental implant. Adhesive dentures are a relatively new dental technology (which is on the border of orthopedic and therapeutic dentistry) the first work in this direction was carried out in the early 80s of the twentieth century. Modern adhesive bridges are divided into two large groups – solid metal and photopolymer (composite) which prevail in practice. The optimal form of the release of the reinforcing element which combines a slight preparation of abutment teeth to a safe depth, high physical and mechanical properties, simple achievement of the anatomical shape of the teeth in the bridge structures of the anterior and posterior teeth is fiberglass in the form of ribbons 2 mm wide, up to 0.5 mm (this is the most effective width and thickness for clinical practice) and braided type. Using adhesive bridges, it is possible to optimally restore the aesthetics of the anterior part of the dentition in one visit without preliminary preparation of adjacent teeth. An example of the manufacture of a photocomposite adhesive prosthesis reinforced with glass fiber for the restoration of a single included defect in the dentition in the frontal area using domestically produced materials is given. Key words: teeth, defect, composite, adhesion, fiberglass.

Abstract:

Background: Dental hard tissue loss renders a tooth restorable or unrestorable. The treatment ranges from endodontic treatment to dental implant. Sometimes patients in need to restore their oral function and esthetics cannot afford those treatments due to a limited financial capability and time availability. Purpose: This case report presents a minimal invasive, single appointment, quick, and affordable alternative treatment to restore morphology, function, and esthetics. Case: A 40 years old male patient suffered enamel-dentin-pulp fracture on central incisor due to trauma. Eventhough the fracture involves pulp exposure, it remains vital. The tooth lacks sound tooth structure for ferrule effect. The patient wished to retain the tooth. Therefore, initial treatment plan comprised of reestablishing ferrule effect, root canal treatment, endodontic post, and porcelain crown. Nevertheless, due to financial and time constraint, patient refused the suggested treatment plan; thus, direct resin composite bridge was suggested. Case Management: Isolation is followed by calcium hydroxide capping of the exposed pulp. After application of etch and adhesive bonding to tooth 11, 21, and 22, nanohybrid resin composite was layered to fabricate the direct composite bridge, bonded to 11 and 21, with the following layering sequence: 1) palatal; 2) proximal; 3) body; 4) labial. The procedure took 1 hour to restore tooth morphology, function, and esthetics. Upon five years follow-up, the tooth remains asymptomatic. The direct resin composite bridge has been serving well. Conclusion: Direct resin composite bridges can be an affordable, quick, and minimal invasive treatment modality resulting in satisfactory esthetics, function, and longevity.

Abstract:

Resin-bonded fixed dental prostheses (RBFDP) are minimally invasive alternatives to traditional full-coverage fixed partial dentures as they rely on resin cements for retention. This study compared and evaluated the tensile bond strength of three different resin-bonded bridge designs, namely, three-unit fixed-fixed, two-unit cantilever single abutment, and three-unit cantilever double-abutted resin-bonded bridge. Furthermore, the study attempted to compare the tensile bond strengths of the Maryland and Rochette types of resin-bonded bridges. Based on the inclusion and exclusion criteria, a total of seventy-five extracted maxillary incisors were collected and later were mounted on the acrylic blocks. Three distinct resin-bonded metal frameworks were designed: three-unit fixed-fixed (n = 30), two-unit cantilever single abutment (n = 30), and a three-unit cantilever double abutment (n = 30). The main groups were further divided into two subgroups based on the retainer design such as Rochette and Maryland. The different prosthesis designs were cemented to the prepared teeth. Later, abutment preparations were made on all specimens keeping the preparation as minimally invasive and esthetic oriented. Impression of the preparations were made using polyvinyl siloxane impression material, followed by pouring cast using die stone. A U-shaped handle of 1.5 mm diameter sprue wax with a 3 mm hole in between was attached to the occlusal surface of each pattern. The wax patterns were sprued and cast in a cobalt–chromium alloy. The castings were cleaned by sandblasting, followed by finishing and polishing. Lastly, based on the study group, specimens for Rochette bridge were perforated to provide mechanical retention between resin cement and metal, whereas the remaining 15 specimens were sandblasted on the palatal side to provide mechanical retention (Maryland bridge). In order to evaluate the tensile bond strength, the specimens were subjected to tensile forces on a universal testing machine with a uniform crosshead speed. The fixed-fixed partial prosthesis proved superior to both cantilever designs, whereas the single abutment cantilever design showed the lowest tensile bond strength. Maryland bridges uniformly showed higher bond strengths across all framework designs. Within the limitations of this study, the three-unit fixed-fixed design and Maryland bridges had greater bond strengths, implying that they may demonstrate lower clinical failure than cantilever designs and Rochette bridges.

Abstract:

Dental pulp-capping is done to preserve vital teeth when the pulp is exposed due to caries, trauma or instrumentation. Various materials are used as pulp-capping agents. The introduction of newer materials requires scientific studies to assess their clinical efficacy. The study was designed as a split-mouth randomized analysis of four pulp-capping agents (calcium hydroxide, mineral trioxide aggregate (MTA), Biodentine and EndoSequence root repair material (ERRM)). Based on selection criteria, 15 orthodontic patients requiring the extraction of four premolars (60 teeth total) were included in the study. After pulp-capping, the teeth were extracted after 8 weeks. We analyzed the extracted teeth using cone-beam computed tomography (CBCT) and histological sections to determine the quality of the dentinal bridge and the pulpal response. Ordinal scores were given based on the completeness of the dentinal bridge, the type of bridge and the degree of pulpal inflammation. Results were analyzed using a Kruskal–Wallis test (p < 0.05) with post hoc Conover values being used when applicable. All four pulp-capping materials elicited dentinal bridge formation (60/60). MTA had the highest scores (10/15) in dentinal bridge formation followed by ERRM (8/15). Both materials showed more samples with complete dentinal bridges (9/15 each) and a favorable pulpal response (15/15). Teeth capped with calcium hydroxide showed more cases of incomplete bridge formation (9/15) and pulpal inflammation. These differences in dentinal bridge formation and pulpal inflammation were statistically significant (p 0.001 and p 0.00005, respectively), with post hoc tests revealing no significant differences between MTA and ERRM (p 0.49 and p 0.71, respectively). MTA and ERRM performed better than the other pulp-capping materials but did not differ significantly from each other. The individual preference for a pulp-capping material may be based on clinical efficacy and handling characteristics.

Abstract:

This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc.) were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

Abstract:

The dental implants have been increasingly used for replacing missing teeth over the past three decades. However, its mechanical strength remains a major concern to dental clinicians and patients. To investigate failure modes and fracture loads of implant-supported fixed partial bridge, eXtended Finite Element Method (XFEM) was employed in this study. The 3D finite element (FE) models simulating full mandibular teeth and implant-supported three-unit fixed partial denture (FPD) were developed to determine the crack initiation and propagation in the dental prostheses. The failure modes and fracture loads are compared for three typical treatment scenarios: namely three-unit FPD supported by two implants at left second premolar and first molar (named as cantilever Model-IIP), second premolar and second molar (bridge Model-IPI), and first and second molars (cantilever Model-PII). The XFEM analyses show that the bridge Model-IPI exhibited considerably high fracture resistance than the other two configurations. Model-IIP displays the worst fracture strength of these three case scenarios. The results provide a basis for clinical assessment of mechanical strength for implant-supported FPD or other restorative devices.

Abstract:

Dental restorations are currently produced mainly by conventional dental technology methods. The automation of the manufacturing process can be achieved by the use of CAD/CAM technology. Basic research on the most important aspects of CAD/CAM fixed dental restorations from the viewpoint of production, information technology, and dentistry/dental technology are the subject of a current article. The aim of this article is practical using of computer aided technologies such as 3D scanning and 5-axis machining for designing and fabrication of dental restorations. It further explains the detailed process of acquiring a digital description of tooth’s shape and its subsequent modification. Attention is drawn to a detailed analysis of dental restorations’ design obtained from a digital description of a tooth in Cercon Art software. The last part of this paper concentrates on the fabrication of dental restorations, which took place at CAD/CAM dental centre in Bratislava, Slovakia. The fabrication was accomplished by 5-axis kinematic structure of machine tools.

Abstract:

Objective The aim of the present study was to investigate Medicare rebate claim trends under the Australian Chronic Disease Dental Scheme (CDDS) over time, region and type of service. Methods CDDS data obtained from the Department of Human Services reflected all Medicare item claims lodged under the CDDS by dental practitioners and processed by Medicare. Retrospective analysis of CDDS rebate claims was conducted. Results The CDDS rebates for the period 2008–13 totalled A$2.8 billion. Just under 81% of claims were from dental practitioners working in major cities. The most frequent rebates were for crown, bridge and implant (32.4%), removable prostheses (22.4%) and restorative services (21.3%). The rebate claims of restorative services, crown and bridge, and removable prostheses per dentist in all regional areas increased over the time of the CDDS. Per capita, the rebates for every type of dental service were lower in the more remote regions. Conclusions Rebate claims increased in each of the last 3 full years of the CDDS across all areas. The majority of Medicare rebate claims were from major city areas and for crown and bridge, removable prostheses and restorative services. The service mix varied between regions. What is known about the topic? The CDDS was described as ‘unsustainable’ from the governmental budgetary perspective, being controversial around the value of the program, ‘poorly targeted’ and having implementation and administrative requirement shortfalls. What does this paper add? The CDDS rebates for the period 2008–13 totalled A$2.8 billion, with just under 81% of claims from dental practitioners working in major cities. The services with the highest rebate claims were crown and bridge, removable prostheses and restorative services. What are the implications for practitioners? In future such schemes, the type of services offered could be reviewed regularly by policymakers in order to control item expenses. The take-up of Government dental schemes may be slow to start, but will tend to increase rapidly over the life of the scheme.

Abstract:

The dental pulp was capped indirectly or directly, or partial vital pulpectomy was performed on the 12 functionally most important teeth of 24 beagle dogs. For pulp capping, calcium hydroxide was used, followed by zinc phosphate as a lining, and the preparation was restored with amalgam or composite material. Histological sections were prepared and examined for degree and type of pulp inflammation (hyperaemia, pulpitis, necrosis or gangrene). Degenerative changes of dental pulp (vacuolation, calcification, amyloid or hyaline changes) were also determined. For indirect pulp capping the width of predentine in crown and root dental pulp was measured, and for direct pulp capping and partial pulpectomy (vital pulpotomy) the width and quality of the dentinal bridge were graded. The radical method of partial vital pulpectomy of the coronal part of the dental pulp in dogs produced better quality and continuity of the dentinal bridge than the less radical method of direct pulp capping. This was particularly obvious in small single root teeth such as incisors.

Dental trauma during tracheal intubation mostly happens in case of poor dentition, restricted mouth opening, and/or difficult laryngoscopy.57-year-old man undergoing laparoscopic radiofrequency ablation of unresectable hepatocellular carcinoma had his dental work detached at induction of anesthesia. Oropharyngeal direct view, manual inspection, fibreoptic nosendoscopy, tracheobronchoscopy, and fiberoptic inspection of the esophagus and stomach were unsuccessful in locating the dislodged bridge. While other possible exams were considered, such as lateral and AP x-ray of head and neck, further meticulous manual “sweepings” of the mouth were performed, and by moving the first and second fingers below the soft palate deep towards the posterolateral wall of the pharynx, feeling consistent with a dental prosthesis was detected in the right pharyngeal recess. Only after pulling the palatopharyngeal arch upward was it possible to grasp it and extract it out with the aid of a Magill Catheter Forceps. Even though the preexisting root and bridge deficits were well reported by the consultant dentist, the patient was fully reimbursed. The lack of appropriate documentation of the advanced periodontal disease in the anesthesia records, no mention of potential risks on anesthesia consent, and insufficient protective measures during airway instrumentation reinforced the reimbursement claim.
