OBJECTIVE: To investigate the dental practitioner's knowledge, attitude and practice towards dental implants. METHODOLOGY: This study was carried out from May'2019 - Oct 2019. 752 dental practitioners who were currently practicing were included in the study. A well-structured questionnaire was used for data collection. SPSS-25 was used for statistical analysis. Spearman correlation was used to find the effect of gender, knowledge and attitude. The P <0.05 was considered statistically significant. RESULTS: In this study 80.9% dental practitioners were aware of the appropriate implant material while, 57.9% had knowledge about the types. 30.3% knew about the implant surface modifications whereas 46.1% dentists were aware of possible implant placement approaches. 49.3% believed that the distance between dental implants to be 3mm and between a dental implant and natural tooth to be 1.5 mm. 76% dentists claimed that dental implants have biomechanical complications. Whereas 67.8% knew about the Branemark's theory of osseointegration. Regarding the attitude of dental practitioners, 28.9% had received implant hands on trainings while 9% felt competent to place an implant. CONCLUSION: This study describes that dental practitioners had an appropriate knowledge of each aspect of implantology. Moreover despite the fact majority felt that they are not competent enough to practice it. Thus, it is important that the curriculum, teaching standards, the materials and methods regarding dental implants need to be reviewed and more exposure of hands-on workshops is to be provided not only for the graduates but also the undergraduates during their clinical learning.

Abstract The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant fracture is one possible complication that results in ultimate failure of the dental implant. Such a complication poses a management crisis even for the most experienced clinician. This article reports on a case of implant fracture, its possible causes, and how the case was managed.

Many patients travel abroad seeking cosmetic dental treatment, in particular dental implants. However, there are hundreds of dental implant systems being used globally by dentists of all training backgrounds. Furthermore, complications can occur that patients may expect their general dental practitioner in the UK to be able to manage. The following report describes the case of a 71-year-old, medically compromised patient who presented with complaints consistent with the immediate failure of dental implants that happened to be placed abroad. On closer examination, the dental implants themselves were highly questionable in their design and placement. An incidental finding was also made in the maxillary sinus. CPD/Clinical Relevance: To acknowledge that implant dentistry is increasing in popularity as patients have the freedom to access dental implant treatment globally. UK dentists are expected to manage these dental implants on the return of patients to the UK who may present with post-operative complications involving unknown dental implant systems.

Numerous clinical observations performed on patients who have achieved dental restorations on implants drew attention to the risk of immediate or late complications. The most common late complications are lost of implant components and fracture of implant. While loss of screw only produce patient discomfort, implant fracture lead to more serious complications and subsequent treatment is extremely difficult. The causes of these complications are static mechanical failure of the implant system and overloading of the assembly [1]. The main function of dental implants is to transfer the load to the surrounding biological tissues. Therefore, the first objective of functional design is to dissipate and distribute biomechanical loads, in order to optimize function on prosthesis built on implants.

Texto completoResumen
Background. Rehabilitation of edentulous jaws with implant-supported prosthesis has become a common practice among oral surgeons in the last three decades. This therapy presents a very low incidence of complications. One of them is the displacement of dental implants into the maxillary sinus. Dental implants, such as any other foreign body into the maxillary sinus, should be removed in order to prevent sinusitis.Methods. In this paper, we report a case of dental implant migrated in the maxillary sinus and removed by means of the bone lid technique.Results and Conclusion. The migration of dental implants into the maxillary sinus is rarely reported. Migrated implants should be considered for removal in order to prevent possible sinusal diseases. The implant has been removed without any complications, confirming the bone lid technique to be safe and reliable.

Sjögren's syndrome (SS) is a complex autoimmune disease that predominantly affects the exocrine glands, notably the salivary and lacrimal glands, resulting in dryness of the mucosa recognized as xerostomia. Chief oral complications reported by patients consist of high caries rate, burning sensation of the mucosa, early tooth loss, intensified tooth wear and repetitive failure of dental restorations. In particular, due to the decreased salivary flow, conventional removable prostheses might irritate the mucosa and lead to painful ulcerations at the borders of the denture. Implant-supported prostheses offer a unique solution to the difficulties experienced by edentulous patients with Sjögren’s syndrome. This research showed no signs of peri-implantitis or peri-implant mucositis during 7-years following the placement of implants. The present study indicates that successful long-term maintenance of dental implants can be also achieved in SS patients.

Introduction: The massive diffusion of dental implant treatments in the last decades leads to the appearance of complications, most of them inflammatory, although important complications have been described as malignant lesions in the vicinity of dental implants. The objective of this article is to describe the cases described in the literature of oral squamous cell carcinoma (OSCC) or clinical variants and metastases, in the vicinity of dental implants and to analyze the possible etiological agents involved. Material and methods: The criteria used were those described in the PRISMA® Declaration for performing systematic reviews. An electronic search was performed on MEDLINE (via PubMed) using the terms MeSH: “dental implants” AND “squamous cell carcinoma” OR “dental implant complications” AND “squamous cell carcinoma”. Results: Thirty-eight articles describing a total of 76 cases of OSCC or clinical variants, as well as metastasis in the vicinity of dental implants, were included. Conclusions: It is not possible to establish a cause-effect relationship between dental implants and the development of OSCC. Its clinical appearance can be confused with periimplantitis, so that, in cases of sudden onset, which do not respond to conventional treatment and/or have associated alterations in sensitivity, a biopsy should be performed.

Implant dentistry constitutes a therapeutic modality in the prosthodontic treatment of partially and totally edentulous patients. This study reports a long-term evaluation of treatment by the early loading of acid-etched surface implants. Forty-eight partially and totally edentulous patients were treated with 169 TSA Defcon® acid-etched surface implants for prosthodontic rehabilitation. Implants were loaded after a healing free-loading period of 6–8 weeks in mandible and maxilla, respectively. Implant and prosthodontic clinical findings were followed during at least 17 years. Clinical results indicate a survival and success rate of implants of 92.9%, demonstrating that acid-etched surface achieves and maintains successful osseointegration. Five implants in three patients were lost during the healing period. Sixty-five prostheses were placed in 45 patients over the remaining 164 implants, 30 single crowns, 21 partially fixed bridges, 9 overdentures, and 5 full-arch fixed rehabilitations. A total of 12 implants were lost during the follow-up period. Mean marginal bone loss was 1.91 ± 1.24 mm, ranging from 1.1 to 3.6 mm. The most frequent complication was prosthetic technical complications (14.2%), followed by peri-implantitis (10.6%). The mean follow-up was of 214.4 months (208–228 months). Prosthodontic rehabilitation with an early-loading protocol over acid-etched surface implants is a successful implant treatment.

Introduction. Biological complications are the most common type of complications around dental implants. They appear in two forms, peri-mucositis and peri-implantitis. The aim of our research was to analyze the above-mentioned complications regarding the time elapsed from implantation and implant loading, as well as regarding the type of dental restoration. Material and methods. 18 patients with self-reported complications were examined at the Department of Periodontology and Oral medicine, School of Dental medicine, University of Belgrade. Each patient filled an anamnestic questionnaire. Clinical examination, including photographic and radiographic documentation have been performed. Results. Clinical examination included 18 patients and 97 implants in total (70% female patients and 30% male patients). The average time elapsed from implants placement was 7.5 years and the average from final dental restoration was 7 years. Periodontitis was diagnosed in 85% of the patients. Complications were more common among the patients with cement-retained restorations. Conclusions. Due to the limitation of our study, we can assume that periodontal disease and cement-retained restorations are the risk factors for genesis and development of the complications around dental implants. The results of our study are in consent with data found in the literature, but in order to confirm these results it is necessary to perform analysis on a larger sample and with longer follow-up.

INTRODUCTION. Osseointegrated implants are actually replacements for natural teeth, and, like natural teeth, they are exposed to various forces. Rejection and bad osseointegration of implants rarely occur today because oral implants are made from biocompatible materials. Most complications are a consequence of badly planned implant loading. OBJECTIVE. The aim of this work was the optimization of the process of planning and inserting oral implants and dentures based on the analysis of the biomechanical problems in implantology. METHOD. In order to determine the influence of the number of cantilevered superstructures, the number of implants and implant microdesign on tensions within the implant and in the peri-implant tissue, a calculation of tensions and deformations was made in a virtual model (control model) using the finite elements analysis. The obtained values served as reference values in the analysis of the results from three experimental models. RESULTS. In the control model, as well as in the experimental models, the first implant bears the heaviest load with dominant contraction tensions, the second one carries significantly weaker straining tensions, the third one carries weak contraction tensions and the fourth one the weakest straining tensions. The values of tensions and deformations have the same sign (-/+), but the absolute values depend on the number of cantilevered superstructures, implant microdesign and the number of inserted implants. CONCLUSION. Knowing the biomechanics of oral implants and the dentures on them allows for proper indication, a good choice of implants and good superstructure design. The prevention measures for bone resorption caused by biomechanical factors are: insertion of symmetrical screw implants and root-shaped cylindrical implants as long and as wide as possible, insertion of implants with the total supporting area expanded, choosing materials that are rigid enough, the right direction of implants, narrowing of the denture occlusal surfaces and location of the contact point at the centre.

Purpose. Nowadays, the advancements in direct metal laser sintering (DMLS) technology allow the fabrication of titanium dental implants. The aim of this study was to evaluate implant survival, complications, and peri-implant marginal bone loss of DMLS implants used to support bar-retained maxillary overdentures.Materials and Methods. Over a 2-year period, 120 implants were placed in the maxilla of 30 patients (18 males, 12 females) to support bar-retained maxillary overdentures (ODs). Each OD was supported by 4 implants splinted by a rigid cobalt-chrome bar. At each annual follow-up session, clinical and radiographic parameters were assessed. The outcome measures were implant failure, biological and prosthetic complications, and peri-implant marginal bone loss (distance between the implant shoulder and the first visible bone-to-implant contact, DIB).Results. The 3-year implant survival rate was 97.4% (implant-based) and 92.9% (patient-based). Three implants failed. The incidence of biological complication was 3.5% (implant-based) and 7.1% (patient-based). The incidence of prosthetic complication was 17.8% (patient-based). No detrimental effects on marginal bone level were evidenced.Conclusions. The use of 4 DMLS titanium implants to support bar-retained maxillary ODs seems to represent a safe and successful procedure. Long-term clinical studies on a larger sample of patients are needed to confirm these results.

Texto completoResumen
The accidental displacement of roots, endodontic materials and dental implants into the maxillary sinus are relatively common complications in dental clinical practice. The purpose of this study is to present four cases of displaced dental implant into maxillary sinus, their treatment as well as the prevention of this condition. There are three different major approaches to remove materials displaced into the maxillary sinus: suction from the socket of an extracted tooth, the classical open surgery via the canine fossa and endoscopic approach. A relevant improvement of surgical techniques previous to, or in association with, the placement of implants in the posterior maxilla, has tremendously expanded the possibilities and indications for such treatments. To decrease the risk for developing side effects, it is recommended that sinus augmentation procedures should be performed before inserting implants in a resorbed upper jaw where sinus penetration is unavoidable. As implant displacement in the paranasal sinuses may be followed by infectious complications, an immediate or early removal of the displaced implants is indicated.

Texto completoResumen
Dental implants are becoming increasingly used in current dental practice. This increased demand has motivated manufacturers to develop varieties of product through design, but also looking for new materials used to improve surface characteristics in order to obtain a better osseointegration. But the increase in the use of implants goes to a consequent increase in the number of failures. These failures are caused either by treatment complications (peri-implantitis), by fatigue breakage under mechanical over-stress, by defective raw material, or due to errors during the insertion procedures. Although they are rare, these complications are serious in dentistry. Before to market a dental implant to clinical practitioners, the product is validated among other determinations in number of biocompatibility research. Raw material issues, details about its structure and properties are less published by the scientific literature, but all this are subject of a carefully analysis of the producers. Breaking of dental implants during surgical procedures, during the prosthetic procedures or during use (chewing, bruxism, accidents, etc.), is the second most common cause of loss of an implant after consecutive peri-implantitis rejection. Although the frequency of this type of failure for a dental implant is much smaller than those caused by the peri-implantitis, a detailed study of broken implants can explain possible causes. The use of scanning electron microscopy (SEM) in the study of the cleave areas explain the production mechanism of cleavages, starting from micro-fissures in the alloy used for the production of dental implants. These micro-fissures in weak areas of the implant (anti-rotational corners of the polygons, etc.) could generate a serious risk of cleavage first time when a higher force is applied.

This systematic review (SR) aimed to evaluate implant survival rate, marginal bone loss (MBL), and biological/prosthetic complications of extra-short 4 mm dental implants. An electronic search without language or date restrictions was performed in five databases and in gray literature for articles published until August 2020. Prospective cohort studies and randomized clinical trials (RCTs) that evaluated the clinical performance of extra-short 4 mm dental implants were included. Studies were independently assessed for risk of bias using the Cochrane Collaboration’s tool. The protocol of this SR was registered in the PROSPERO database under number CRD42019139709. Four studies were included in the present SR. There was no significant difference in implant survival rate (p = 0.75) between extra-short 4 mm and long implants. After 12 months of function, the extra-short implants had a significantly (p = 0.003) lower marginal bone loss (MBL) rate when compared to long implants. Extra-short implants had a lower number of biological and prosthetic complications when compared to long implants. After 12 months of follow-up, extra-short 4 mm dental implants placed in the mandible exhibit satisfactory clinical outcomes concerning implant survival rate and MBL when compared to longer implants, with a low number of biological and prosthetic complications. A higher number of RCTs with longer follow-up is necessary for the future.

Objective. To evaluate horizontal bone gain and implant survival and complication rates in patients treated with titanium meshes placed simultaneously with dental implants and fixed over them. Methods. Twenty-five patients treated with 40 implants and simultaneous guided bone regeneration with titanium meshes (i–Gen®, MegaGen, Gyeongbuk, Republic of Korea) were selected for inclusion in the present retrospective multicenter study. Primary outcomes were horizontal bone gain and implant survival; secondary outcomes were biological and prosthetic complications. Results. After the removal of titanium meshes, the CBCT evaluation revealed a mean horizontal bone gain of 3.67 mm (±0.89). The most frequent complications were mild postoperative edema (12/25 patients: 48%) and discomfort after surgery (10/25 patients: 40%); these complications were resolved within one week. Titanium mesh exposure occurred in 6 patients (6/25 : 24%): one of these suffered partial loss of the graft and another experienced complete graft loss and implant failure. An implant survival rate of 97.5% (implant-based) and a peri-implant marginal bone loss of 0.43 mm (±0.15) were recorded after 1 year. Conclusions. The horizontal ridge reconstruction with titanium meshes placed simultaneously with dental implants achieved predictable satisfactory results. Prospective randomized controlled trials on a larger sample of patients are required to validate these positive outcomes.

This systematic review and meta-analysis set out to assess the clinical behavior of mandibular implant-supported fixed complete dental prostheses (ISFCDP) on three dental implants by analyzing implant and prosthetic survival rates, marginal bone loss, biological/technical complications, and patient-reported outcomes. The review was conducted according to PRISMA guidelines. Electronic searches were conducted in the Medline (PubMed), Web of Science, and Cochrane databases, complimented by a manual search in specialist journals for relevant articles published up to February 2021. The Newcastle-Ottawa Quality Assessment Scale tool was used to assess the quality of evidence in the studies reviewed. The study included 13 articles with 728 patients treated with 2184 implants. A mean implant survival rate of 95.9% (95% CI: 94.6–97.3%) and a prosthetic survival rate of 97.0% (95% CI: 95.7–98.3%) were obtained over 1–6-year follow-up periods. Mandibular implant-supported fixed complete dental prostheses on three dental implants would appear to be a viable option for restoring the edentulous mandible in comparison with mandibular ISFCDP on more than three implants. Further comparative studies are needed, with adequate protocols, as well as sufficient sample sizes and follow-up periods to confirm these findings.

Texto completoResumen
With the growing use of dental implants, the incidence of implants’ failures grows. Late treatment complications, after reaching full osseointegration and functionality, include mechanical failures, such as fracture of the implant and its components. Those complications are deemed severe in dentistry, albeit being usually considered as rare, and therefore seldom addressed in the clinical literature. The introduction of dental implants into clinical practice fostered a wealth of research on their biological aspects. By contrast, mechanical strength and reliability issues were seldom investigated in the open literature, so that most of the information to date remains essentially with the manufacturers. Over the years, implants have gone through major changes regarding the material, the design, and the surface characteristics aimed at improving osseointegration. Did those changes improve the implants’ mechanical performance? This review article surveys the state-of-the-art literature about implants’ mechanical reliability, identifying the known causes for fracture, while outlining the current knowledge-gaps. Recent results on various aspects of the mechanical integrity and failure of implants are presented and discussed next. The paper ends by a general discussion and suggestions for future research, outlining the importance of mechanical considerations for the improvement of their future performance.

ABSTRACTAfter tooth loss, an individual may seek tooth replacement so that his/her function and esthetics could be restored. Clinical prosthodontics, during the past decade, has significantly improved and developed according to the advancements in the science and patient's demands and needs. Conventional options in prosthodontics for substituting a missing single tooth include the removable partial denture, partial and full coverage bridgework, and resin-bonded bridgework. Dental implants have gained increasing popularity over the years as they are capable of restoring the function to near normal in both partial and completely edentulous arches. With substantial evidence available, fixed implant-supported prosthesis are fully acknowledged as a reliable treatment option for the replacement of single or multiple missing teeth nowadays. While dental implants are increasingly becoming the choice of replacement for missing teeth, the impediments associated with them are progressively emerging too.

Despite the recent economic downturn, the dental implant market continues to grow year on year. Many more dentists are involved in the placement restoration of dental implants and dental implants are being placed in an extended range of clinical scenarios. Dental implant therapy remains a high risk area for the inexperienced in terms of civil negligence claims and General Dental Council hearings. Risk can be mitigated by: • Ensuring appropriate indemnity • Complying with the published requirements for training • Maintaining detailed and extensive clinical records • Completing the initial phases of history, examination and investigations robustly • Recording a diagnosis • Providing a bespoke written treatment plan that includes details of the need for treatment, the treatment options (the risks and benefits), the phases of treatment, the costs of treatment, the expected normal sequelae of surgery, the risks and complications of implant therapy and the requirement for future maintenance. The provision of treatment that is different in nature or extent to that agreed can result in a breach of contract as well as a claim for negligence • Engaging sufficiently with the patient to obtain consent • Providing written postoperative instructions detailing emergency arrangements, patients who are anxious or in pain may not retain oral information • Making a frank disclosure of complication or collateral damage • Considering referral at an early stage particularly if reparative surgery is required The stress of complications or failure may impair a dentist's normally sound judgement; there may be financial pressure, or concerns regarding reputation. In some cases, dentists avoid making a frank disclosure, feel obliged to undertake complicated reparative surgery, fail to make a timely referral, fail to respond appropriately to patient's concerns and in some cases attempt to alter the clinical records. However, in the best of hands and without negligence complications can and do occur. Complications that occur in the presence of good planning and communication and are managed appropriately do not amount to negligence, and are unlikely to lead to a successful claim.

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 Introduction Dental implants are one of the common lines of treatment used for the treatment of missing tooth. Various risk factors are responsible for the failure of the dental implants and occurrence of postoperative complications. Bruxism is one such factor responsible for the failure of the dental implants. The actual relation between bruxism and dental implants is a subject of long-term controversy. Hence, we carried out this retrospective analysis to assess the complications occurring in dental implants in patients with and without bruxism. Materials and methods The present study included 1100 patients which were treated for rehabilitation by dental implant procedure at 21 dental offices of Ghaziabad (India) from 2004 to 2014. Analyzing the clinical records of the patients along with assessing the photographs of the patients was done for confirming the diagnosis of bruxism. Clinical re-evaluation of the patients, who came back for follow-up, was done to confirm the diagnosis of bruxism. Systemic questionnaires as used by previous workers were used to evaluate the patients about the self-conscience of the condition. Estimation of the mechanical complications was done only in those cases which occurred on the surfaces of the restoration of the dental implants. All the results were analyzed by Statistical Package for Social Sciences (SPSS) software. Student's t-test and Pearson's chi-square test were used to evaluate the level of significance. Results In both bruxer and non-bruxers, maximum number of dental implants was placed in anterior maxillary region. Significant difference was obtained while comparing the two groups for dimensions of the dental implants used. On comparing the total implant failed cases between bruxers and non-bruxers group, statistically significant result was obtained. Statistically significant difference was obtained while comparing the two study groups based on the health parameters, namely hypertension, diabetes, and smoking habit. Conclusion Success of dental implant is significantly affected by bruxism. Special attention is required in such patients while doing treatment planning. Clinical significance For the long-term clinical success and survival of dental implants in patients, special emphasis should be given on the patient's deleterious oral habits, such as bruxism as in long run, they influence the stability of dental implants.

The aim of this study was to assess the long-term clinical behavior of straight implants in comparison with intentionally tilted dental implants (ITDI) supporting fixed restorations in partial or total edentulous arches, analyzing implant survival and success rates, complications, and marginal bone loss (MBL) after >5 years of function. An electronic search was conducted in five electronic databases (MEDLINE/Pubmed, Embase, Web of Science, Scopus, and Cochrane Central Register of Controlled Trials) supplemented by a manual search. The electronic and manual search identified 1853 articles, of which 8 articles were selected for analysis. Out of a total of 3987 dental implants, 2036 were axial dental implants and 1951 tilted. Similar results were found in implant survival or overall implant success rates. Moreover, no statistically significant differences were found in MBL (p = 0.369; MD 0.116 mm (−0.137; 0.369) 95% CI) The prosthodontic/biological complications reported in the articles were very diverse and irregularly distributed. This systematic review suggests that there is no difference between tilted compared with straight dental implants in the medium-long term (>5 years). However, further research is needed to generate long-term data and confirm the present review’s findings.

The insertion of dental implants containing titanium can be associated with various complications (eg, hypersensitivity to titanium). The aim of this article is to evaluate whether there are existing studies reporting on PEEK (polyetheretherketone) as an alternative material for dental implants. A systematic literature search of PubMed until December 2010 yielded 3 articles reporting on dental implants made from PEEK. One article analyzed stress distribution in carbon fiber-reinforced PEEK (CFR-PEEK) dental implants by the 3-dimensional finite element method, demonstrating higher stress peaks due to a reduced stiffness compared to titanium. Two articles reported on investigations in mongrel dogs. The first article compared CFR-PEEK to titanium-coated CFR-PEEK implants, which were inserted into the femurs and evaluated after 4 and 8 weeks. The titanium-coated implants showed significantly higher bone-implant contact (BIC) rates. In a second study, implants of pure PEEK were inserted into the mandibles beside implants made from titanium and zirconia and evaluated after 4 months, where PEEK presented the lowest BIC. The existing articles reporting on PEEK dental implants indicate that PEEK could represent a viable alternative material for dental implants. However, further experimental studies on the chemical modulation of PEEK seem to be necessary, mainly to increase the BIC ratio and to minimize the stress distribution to the peri-implant bone.

Purpose. To present a digital technique for the fabrication of custom-made subperiosteal implants and to report on the survival and complication rates encountered when using these fixtures. Methods. The data used for this retrospective clinical study were derived from the medical records of five different private dental practices. Inclusion criteria were patients over the age of 60, treated with custom-made direct metal laser sintering (DMLS) titanium subperiosteal implants (Eagle-Grid®, BTK, Dueville, Vicenza) during a two-year period (2014-2015) and restored with fixed restorations; all enrolled patients needed to have complete pre- and postoperative clinical and radiographic documentation, with at least 2 years of follow-up. Exclusion criteria were smoking and bruxism. The main outcomes looked at were implant survival and complications. Results. Seventy patients (39 males and 31 females, aged 62-79 years) who had been treated with custom-made DMLS titanium subperiosteal implants were enrolled in this study. After 2 years of follow-up, three implants were lost due to recurrent, untreatable infections; the survival rate was therefore 95.8% (67/70 implants). Four patients reported pain/discomfort/swelling after implant placement; the incidence of immediate postoperative complications was therefore 5.7% (4/70 implants). During the follow-up period, one patient suffered from recurrent infections classified as a biologic complication; the incidence of biologic complications was therefore 1.4% (1/67 surviving implants). Finally, four patients experienced prosthetic problems with their implant-supported restorations during the provisional phase (fracture of the acrylic restoration) and two patients had ceramic chipping of the definitive restoration; the incidence of prosthetic complications was therefore 8.9% (6/67 surviving implants). Conclusions. Within the limits of the present study (limited follow-up time and low number of patients treated, retrospective design), the application of custom-made DMLS titanium subperiosteal implants showed satisfactory implant survival (95.8%) and low complication rates. Further studies are needed to confirm the positive outcomes found in this research.

Introduction. Peri-implantitis is a condition of the tissues adjacent to dental implants, which can occur in patients with implant-prosthetic restorations, following inadequate prophylactic measures. However, these peri-implants, untreated or improperly treated, can lead over time to quite severe complications, which can quickly turn into emergencies of low, medium or increased intensity in the usual dental care. Purpose. Peri-implantitis is not a major dental emergency, but ignoring and/or treating it incorrectly can lead to complications that are considered major in dentistry. That is why we tried through this study to verify the knowledge related to peri-implantitis as well as the complications that may arise from the nontreatment of these diseases, among the practitioners involved in this field. Material and method. The study was conducted with the help of 37 specialists involved in implantprosthetic treatments, aged between 37 and 53 years, using a 7-point questionnaire. Results and discussions. The results show the concern of specialists in the field of oral implantology regarding peri-implantitis, as well as the complications arising from them. Conclusions. Knowing the causes but also the complications arising from peri-implantitis are very important for the creating preventive programs, which with a reduced effort bring the long-term success of implant supported restorations.

The accidental migration (i.e., displacement) of dental implants into the maxillary sinus is a relatively common complication in dental clinical practice. Here, we report the extremely rare nasal cavity migration of a dental implant in a 23-year-old man. Considering the superficial location of the dental implant and the absence of oronasal fistula formation, we attempted to remove the implant via endoscopy, nasal bayonet forceps, curved hooks, and suction in an ambulatory surgery setting with the patient under local anesthesia. Importantly, we were able to extract the implant with only minor complications. The patient received medication for 2 weeks and exhibited uneventful healing. Our findings may be useful for physicians and dentists who encounter similar situations in clinical practice.

Texto completoResumen
In fully edentulous patients, the support of a lower dental prosthesis by two implants could improve the chewing ability, retention, and stability of the prosthesis. Despite high success rates of dental implants, complications, such as peri-implantitis, do occur. The latter is a consequence of crestal bone loss and might be related to the implant surface and peri-implant soft tissue thickness. The aim of this paper is to describe the effect of implant surface roughness and soft tissue thickness on crestal bone remodeling, peri-implant health, and patient-centered outcomes. The mandibular overdenture supported by two implants is used as a split-mouth model to scrutinize these aims. The first study compared implants placed equicrestal to implants placed biologically (i.e., dependent on site-specific soft tissue thickness). The second clinical trial compared implants with a minimally to a moderately rough implant neck. Both studies reported an improvement in oral health-related quality of life and a stable peri-implant health after three years follow-up. Only equicrestal implant placement yielded significantly higher implant surface exposure, due to the establishment of the biologic width. Within the limitations of this study, it can be concluded that an implant supported mandibular overdenture significantly improves the quality of life, with limited biologic complications and high survival rates of the implants.

Background. Despite successful results of implant therapy, complications occasionally occur in challenging situations.Apart from academic courses for implantology, dental associations also offer training courses for general practitioners.We sought to assess dentists' attitude towards peri-implant diseases. Methods. The subjects in thisquestionnaire-based cross-sectional study consisted of dentists participating in the annual congress of the Iranian Dental Association in 2013, whose knowledge and attitudes towards peri-implant diseases were assessed using a five-section questionnaire (implant therapy training, peri-implant soft tissue assessment, peri-implant diseases and treatment planning for peri-implant diseases). Data were analyzedwith SPSS 22, using descriptive and analytical methods. Results. The results showed that due to extensive placement of implants and high prevalence of complications, academic and organized training courses are essential. Conclusion. The results showed that due to extensive placement of implants and high prevalence of complications, academic and organized training courses are essential.

Sputtered hydroxyapatite coated implant has investigated as an implant with novel surface coating for dental implant. The aim of this study was to evaluate the 10 years clinical outcome regarding marginal bone loss around implants, success rate, survival rate, biological and prosthetic complication and patients subjective satisfaction for the implant with sputtered hydroxyapatite coating in human. Sixteen patients with 30 implants were employed for this study. One-piece, sputtered hydroxyapatite coated implants were placed in premolar and/or molar sites with one or two missing tooth. Ten years after implant placement, the marginal bone level change was evaluated by periapical radiograph. Incidence of peri-implant diseases and prosthetic complications were also addressed. Patient satisfaction was analyzed by Oral Health Impact Profile questionnaire. The mean marginal bone loss was 0.74 ± 1.41 mm. Survival and success rates were 96.7% and 86.7% respectively. Three implants (10.0%) in 3 patients (18.8%) were affected by peri-implantitis. Five implants (16.7%) in 4 patients (25%) had chipping of veneering material on prosthesis. One implant (3.3%) in a patient (6.3%) was fractured and removed. Mean score of Oral Health Impact Profile was 41.6 ranged from 3 to 89. Sputtered hydroxyapatite surface showed comparable marginal bone stability in 10 years result.

Dental implant treatment is an important therapeutic modality with documented long-term success for replacement of missing teeth. However, dental implants can be susceptible to disease conditions or healing complications that may lead to implant loss. This case-control study identified several risk indicators associated with failure such as smoking and alcohol consumption. The use of postoperative antibiotics or wide-diameter implants may significantly reduce implant failure. Knowledge of patient-related risk factors may assist the clinician in proper case selection and treatment planning.

The development of dentistry at the present stage opens up new possibilities in the treatment of adentia by intraosseous implantation of artificial supports for dentures, which opened up new opportunities for improving the quality of comprehensive rehabilitation of dental patients. The development of new methods of surgical interventions and prosthetics, the creation of new implant systems help us to increase the life of dentures on implants and to improve the quality of life of patients.
Aim of the study. Literary sources analysis with the study of possible complications and their causes at various stages of patient rehabilitation with dental implants in patients with complete absence of teeth.
Materials and methods. The review and analysis of scientific-medical literature of 2013-2019 years was conducted, according to the databases Scopus, Web of Science, Med Line, The Cochrane Library, EMBASE, Global Health, CyberLeninka, RINC. Attention is focused on the main causes of patient rehabilitation with dental implants in patients with complete absence of teeth.
Results of the studies and their discussion. The method of dental implantation is increasingly used in practical dentistry in the replacement of various defects in the dentition. Dental implants dramatically increased the quality of orthopedic rehabilitation of patients due to the possibility of using fixed dentures in the replacement of dentition defects in both partial and complete adentia. It is worth noting that along with the positive results of implantation, complications are also observed. Removable prostheses on implants can be divided into two groups: fixed on separate implants with spherical abutment or on the beam connecting the implants. The increased interest in this method of treatment is due to a variety of clinical situations, characteristics of the prosthetic bed, the development of new technologies for the construction of prostheses; an increase in the number of patients satisfied with stabilization and retention of prostheses due to implants. The most important stage ensures the further success of the proposed comprehensive treatment of patients, a thorough examination, diagnosis, determination and compliance with indications and contraindications for dental implantation in conditions that are far from optimal. Inadequate consideration of the characteristics of the somatic and dental anamnesis, complaints, motivation and expectations of the patient from the upcoming treatment, examination data, clinical examination, assessment of the functional state of the patient’s dentofacial system, level of oral hygiene, can lead to unjustified expectations of the patient, local and general complications.
Conclusions. Advances in dental science, the emergence of the latest technologies in our time allow us to approach the problem of rehabilitation of patients with a complete absence of teeth in the lower jaw using removable and fixed prostheses based on dental implants.

Dental implants are now broadly used to replace missing teeth, and the presence of infectious complications is rising. Dental implant therapy as a local risk factor for the onset of osteomyelitis and its management have not been widely explored. Here, we report an unusual case of mandibular suppurative osteomyelitis caused by Streptococcus intermedius in a healthy and immunocompetent patient secondary to mandibular implants. We describe how surgery combined with systemic application of antibiotics allowed conservation of the dental implants in the mandibular bone, discuss the probable source of contamination, and present the follow-up of the osteomyelitis.

The number of dental implants performed at the dental reception is steadily increasing. Along with this increased and the frequency of occurrence postprostatectomy complications in dental implantation. One of the main tasks of a dentist is early detection of the initial signs of inflammation of the parotid tissue, leading to mucositis. If you do not act on the site of inflammation in a timely manner, the destruction of bone tissue around the implant will begin with the development of peri-implantitis. In this work, we conducted a retrospective analysis of the frequency of occurrence of mucositis and periimplantitis. An algorithm for diagnostic measures has been developed. The patients were determined by the hygienic index, the iodine number of Svrakov, the degree of bleeding, and the depth of probing of the dental sulcus. The implant stabilization was determined using amplitude-frequency analysis. A detailed periodontal screening was performed to assess the condition of the gums and identify pathological processes occurring in the tissue surrounding the implants. The condition of the cortical plate and parotid bone tissue was evaluated radiologically. The developed algorithm for diagnostic examination of patients with postprotetic complications during dental implantation helps to detect inflammation in an early period, which in turn allows to preserve the integrity of the tooth.

The aim of the present study was to evaluate the long-term outcome of immediately loaded full-arch, fixed, one-piece prostheses supported by dental implants inserted in completely edentulous maxillae and mandibles. Twenty-eight completely edentulous jaws in 27 patients were treated with screw-fixed provisional prostheses on the same day as implant insertion. A total of 189 implants were inserted into the jaws of the patients. All provisional prostheses were the one-piece bridge type and were made with acrylic resin. Final restoration was performed more than 2 months after surgery. Implant survival rate, prosthesis success rate, and complications during the follow-up period were evaluated. Implant size (diameter and length) and bone quality (Hounsfield units) of the region of the implant were also analyzed. Mean follow-up time was 77.9 months. The cumulative survival rate of the implants was 100%, and the success rate of the prostheses was also 100% during the observation time. Although 3 types of minor complications occurred in 10 jaws (10/28; 35.7%), no major complications were found. Immediate loading of dental implants produces an equivalent outcome as that reported in previous studies using conventional loading. We believe this study not only adds to the immediate loading data but also confirms that the immediate loading technique may be most advantageous strategy for edentulous patients.

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.

AbstractObjective:We present two cases of dental implant migration into the maxillary sinus, with subsequent removal via image-guided, transnasal endoscopy.Method:Presentation of clinical cases, together with a literature review of alternative surgical techniques, the theories behind implant migration, and the benefits of an image-guided, endoscopic approach.Results:One patient was asymptomatic, and the other had begun to experience sinogenic symptoms after implant displacement. Both patients presented to the ENT clinic, and both underwent the BrainLab protocol to generate computed tomography images for navigational reconstruction. Transnasal endoscopy was carried out with this guidance, and the implants were removed successfully in both cases. Previously used surgical techniques such as the Caldwell-Luc procedure or extraction through the tooth socket have higher rates of conversion to open procedures, more damage to the nasal sinuses and higher post-operative complication rates compared with the transnasal endoscopic approach.Conclusion:Both patients underwent successful removal of their migrated dental implants with no complications, and neither required any follow-up intervention.

Short 6 mm dental implants are considered as an alternative to the maxillary sinus elevation and bone augmentation procedure where there is a reduced alveolar ridge height. The aim of this study was to compare the implant survival rate between short dental implants (6 mm) and regular length implants (11–13 mm) when placed in combination with bone grafting and loaded with a single non splinted crown, seven years after placing the implant. It was conducted as a controlled clinical study of 30 patients with partial edentulism in the posterior maxilla. The protocol included radiological and clinical evaluation of the C/I ratio (length of the superstructure divided by the length of the implant crestal part), marginal bone level (MBL), ultrasonography measurement of soft tissue surrounding implant (STT), patient-reported outcomes, and biological and technical complications. A total number of 28 implants (93%) remained integrated during follow-up period. MBL of 0.50 and 0.52 mm was observed for short implants and regular implants, respectively. MBL was checked for correlation with STT, and a negative correlation was found between MBL: STT. Our study has demonstrated a significantly lower implant survival rate for short implants compared to regular implants (87% compared to 100%). Despite the loss of several implants, good clinical results were achieved in the remaining implants in both groups. It is, therefore, worth considering short implants as an alternative to regular implants with a sinus lift surgery.

This study evaluated the effect of local application of platelet-rich plasma (PRP) on the outcome of early loaded implants. Two implants were placed in the posterior region or bilaterally symmetric to the median line of the maxilla. Then, PRP was either applied or not applied to the implant sockets. Outcome measures were prosthesis and implant success as well as biological and prosthetic complications. Stability of individual implants was assessed manually and with a resonance frequency analysis device. The implant stability quotient (ISQ) was recorded on the operation day, on postoperative day 4, and at postoperative week 1. At the end of the first postoperative week, implants with ISQ values >60 were early loaded on day 7 with metal-ceramic crowns. Measurements were repeated at postoperative weeks 2, 3, and 4 and at postoperative months 6, 12, 24, and 36. One of the 64 implants was dropped out after 3 months of loading. No prosthesis failed. There were no prosthetic complications. Statistical analysis revealed significant differences between ISQ values of PRP and non-PRP implants on the operation day. Moreover, no statistically significant differences were found between ISQ values of PRP and non-PRP implants in the follow-up periods (P > .05). No appreciable clinical effect was observed when using PRP in the maxilla.

An objective assessment of the morphofunctional characteristics of the state of soft tissues and bone structures adjacent to the dental implant allows to control the dynamics of the processes of osseointegration in the jaw-dental implant system. The aim of the work was to investigate the level of the β-CrossLaps, С-reactive protein (CRP), osteocalcin markers after orthopedic treatment of patients using dental implant supported advanced dental restoration technologies, to perform a biochemical analysis of the oral fluid of patients after restoration using dental implants and new two-part dental implants. In patients of the index group (52 people), the removable prostheses with metal frame and fixing elements or the commercially available dental implant supported removable prostheses were installed. For the patients of the control group (12 people), the commercially available dental implant supported removable prostheses of acrylic plastics were constructed. For all the patients after 6 months the level of β-CrossLaps, CRP, osteocalcin markers in the oral fluid was analysed. In patients of the index group, the average content of β-CrossLaps was 0.0126 ± 0.002 ng/ml, in the control group it was 0.0147 ± 0.002 ng/ml. The average content of the CRP in patients of the index group was 0.358 ± 0.019 mg/l, in patients of the control group it was 0.78 ± 0.01 mg/l. In patients of the index group, the average content of osteocalcin was 1.46 ± 0.25 ng/ml, in the control group it was 1.98 ± 0.31 ng/ml. It has been shown that biochemical markers of the oral fluid can be used to predict complications after the dental implants installation. Restoration with two-part dental implants of modern design is associated with fewer complications.

An increase in the number of implants placed has led to a corresponding increase in the number of complications reported. The complications can vary from restorative complications due to poor placement to damage to collateral structures such as nerves and adjacent teeth. A large majority of these complications can be avoided if the implant has been placed accurately in the optimal position. Therefore, the aim of this in vitro pilot study was to investigate the effect of freehand (FH) and fully guided (FG) surgery on the accuracy of implants placed in close proximity to vital structures such as the inferior alveolar nerve (IAN). Cone-beam computed tomography (CBCT) and intraoral scans of six patients who have had previous dental implants in the posterior mandible were used in this study. The ideal implant position was planned. FG surgical guides were manufactured for each case. In this study, the three-dimensional 3D printed resin models of each of the cases were produced and the implants placed using FG and FH methods on the respective models. The outcome variables of the study, angular deviations were calculated and the distance to the IAN was measured. The mean deviations for the planned position observed were 1.10 mm coronally, 1.88 mm apically with up to 6.3 degrees’ angular deviation for FH surgery. For FG surgical technique the mean deviation was found to be at 0.35 mm coronally, 0.43 mm apically with 0.78 degrees angularly respectively. The maximum deviation from the planned position for the apex of the implant to the IAN was 2.55 mm using FH and 0.63 mm FG. This bench study, within its limitations, demonstrated surgically acceptable accuracy for both FH and FG techniques that would allow safe placement of implants to vital structures such as the IAN when a safety zone of 3 mm is allowed. Nevertheless, a better margin of error was observed for FG surgery with respect to the angular deviation and controlling the distance of the implant to the IAN using R2 Gate® system.

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.

ABSTRACT Objective To determine whether dental implants impress oral lesions, and to evaluate the nature of their effect on the lesions. Materials and methods A comprehensive search was done via Google and PubMed for articles (including case reports and literature reviews) containing the keywords ‘oral squamous cell carcinoma’ (OSCC), ‘oral lichen planus’ (OLP), ‘lichenoid contact reaction’ (LCR), ‘osseointegrated implants’, and ‘dental implants’, in the last 10 years (2002-2012). Results The study included 24 articles involving patients with dental implants, and some oral lesions (e.g. oral lichen planus and oral squamous cell carcinoma) or with a history of lesions. In these publications, there is evidence suggesting the possibility of emergence, exacerbation, recurrence, or even malignant transformation of the oral lesions after implant placement in some cases. Conclusion Based on our review of the literature, implant treatment does not seem to be completely safe under any circumstances, but may have some complications in subjects with certain diseases (e.g. oral lesions, autoimmune diseases, malignancies, allergic reactions, etc.). Therefore prior to treatment, patients should be fully informed of the risks. Clinical significance Implant treatment is best done with caution in patients with cancer or mucocutaneous disorders.

ABSTRACT Aim Minimally invasive method for retrieving displaced objects like implants from the maxillary antrum with minimal complications. Background Minimal invasive endoscopic surgery has been developed for various indications in the craniomaxillofacial area. Case description In this article, a technique for endoscopic removal of a dental implant displaced into the maxillary sinus is presented. Access to the implant was achieved transorally via the canine fossa. The endoscopic surgical approach described was reliable and minimally invasive for removing dental materials displaced into the maxillary sinus. Conclusion Transantral endoscopic surgery is a reliable, minimally invasive method for retrieving displaced objects from the maxillary antrum with minimal complications.
