Resumen
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.

Resumen
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.

Resumen
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.

Resumen
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.

Resumen
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.

Resumen
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.

Resumen
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.

Resumen
Intrinsecamente, todo procedimento cirúrgico apresenta um certo índice de intercorrências e/ou complicações associadas. Hemorragias, infecções, parestesias ou disestesias e perda primária dos implantes são algumas das intercorrências e complicações mais comuns relacionadas a procedimentos cirúrgicos para implantodontia. Este estudo avaliou retrospectivamente o índice de intercorrências e complicações após cirurgia para a instalação de implantes dentais osteointegráveis. Foram avaliados, retrospectivamente, 660 prontuários clínicos de pacientes submetidos à instalação de implantes osteointegráveis no período 8 anos atendidos na Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba - Unicamp. Os resultados demonstraram que houve um maior índice de intercorrências e complicações quando os pacientes eram atendidos por alunos de especialização (p= 0,015) e quando o exame por imagem realizado era somente a radiografia panorâmica convencional (p= 0,011). Os resultados demonstraram também um maior índice de intercorrências e complicações nos pacientes quando estes eram submetidos a procedimentos cirúrgicos de reconstrução óssea alveolar (p< 0,0001). A presença de infecção pós-operatória influenciou significativamente para o aumento no índice de perda primária de implantes (p< 0,0001).
Intrinsically, every surgical procedure presents a certain rate of associated intercurrences and/or complications. Hemorrhages, infections, paresthesias or dysesthesias and primary loss of implants are some of the most common intercurrences and complications related to surgical procedures in implant dentistry. This study conducted a retrospective evaluation of the rate of intercurrences and complications related to patients submitted to osseointegratable dental implant placement. A retrospective evaluation was made of 660 clinical record charts of patients submitted to osseointegratable dental implants in the period of 8 years, attended in the Oral and Maxillofacial Surgery Department of Piracicaba Dental School - Unicamp. The results showed that there was a higher rate of intercurrences and complications when patients were attended by residents (p= 0.015) and when the panoramic radiograph was the only preoperative image exam requested (p= 0.011). The results also showed a higher rate of intercurrences and complications in patients when they were submitted to surgical procedures of alveolar bone reconstruction (p< 0.0001). The presence of post-operative infection had a significant influence on the increase in the primary loss of implants (p< 0.0001).

Resumo: Existem várias pesquisas na literatura que relatam fatores considerados de risco para o insucesso dos implantes dentais. Porém, alguns estudos têm gerado controvérsia nos resultados. Alguns autores inclusive contra-indicam o tratamento de implantes dentais na presença destes fatores tais como doenças sistêmicas, abuso de substâncias nocivas à saúde, procedimentos reconstrutivos prévios à implantodontía, complicações pós-operatórias, entre outros fatores, quando alguns estudos demonstram que estes isoladamente representam apenas uma pequena parcela dos insucessos na implantodontia, sendo não significativos. Assim, o objetivo desse trabalho foi avaliar os fatores que podem influenciar na perda tardia dos implantes dentais, por meio de prontuários clínicos dos pacientes que foram tratados com implantes osseointegráveis para reabilitação implantossuportada no período de junho de 2001 a julho de 2006 pela Área de Cirurgia Buco-Maxilo- Facial da Faculdade de Odontologia de Piracicaba . Unicamp. Foram estudados diversos fatores dos pacientes em todos os grupos, tais como gênero, idade, queixa principal, história médica, procedimentos reconstrutivos, procedimentos implantodônticos, desenho do implante, complicações, procedimentos protéticos, acompanhamento mínimo de um ano após carga protética e perda dos implantes. Além disso, cada um destes fatores foi avaliado nos pacientes que apresentaram alguma perda tardia nos tratamentos implantodônticos, com a finalidade de obter a relação destes e sua influência na perda tardia dos tratamentos com implantes dentais. Forem incluídos 432 pacientes na avaliação deste estudo com um índice de 89,3% de sucesso no tratamento com implantes dentais. Perda primaria foi apresentada em 28 pacientes (6,4%) e Perda Tardia em 21 pacientes (4,8%). Dos pacientes que apresentarem perda tardia, nenhum deles relatou consumir substâncias nocivas à saúde, sete apresentavam alguma doença sistêmica e seis forem submetidos a procedimentos reconstrutivos prévios à colocação dos implantes dentais. Os fatores tabagismo, doenças sistêmicas, procedimentos reconstrutivos e complicações nos tratamentos cirúrgicos não resultaram ser significativos nos índices de perda tardia. Estudos prospectivos são necessários para um maior entendimento desses insucessos no tratamento de implantes dentais.
Abstract: Researches in literature considered some factors to be related to failure of dental implants treatments. However, some other studies have generated controversy in those results. Some authors also contraindicated dental implants treatment in presence of these factors like systemic diseases, substance abuse, bone grafting before implant installation, postoperative complications and others factors; when some studies demonstrate that these factors, separately, represent only one small parcel of failures in the dental implantology, being not significant. Thus, the objective of this work was to evaluate the factors that can influence in the delayed failure of dental implantations, by means of formularies of patients who had been treated with dental implants in the period of June of 2001 through July of 2006 at the Oral and Maxillofacial Surgery Department of the Piracicaba Dental School - Unicamp. The groups, such as gender, age, main complaint, medical history, reconstructive procedures, dental implant procedures, complications, prosthetic procedures, a minimum follow-up of one year after prosthetic load and implants failure, had been studied in this research. Moreover, each of these factors had been evaluated in the patients who had presented some delayed failure on dental implants treatments, with the purpose to establish any relation of these factors and their influence in the delayed failure of dental implant treatments. 432patients were included on the evaluation of this study with a success rate of 89.3% on dental implants treatment. Primary failure on dental implants presented on 28 patients (6.4%) and 21 patients (4.8%) presented delayed failure. Patients who presented delayed failure did not abuse substances, seven patients had a systemic disease and six treated previously with bone graft. Smoke, systemic disease, reconstructive procedures and complications during surgical treatments had not resulted to be significant on delayed failure indices. Prospective studies are necessary for a best comprehension of these failures in the treatment of dental implants.

Resumen
The purpose of this study was to ascertain whether simplifying mandibular overdenture treatment utilising single stage surgery and immediate prosthetic loading of a single implant, will achieve similar implant success rates and functional improvement to that expected using conventional techniques. As part of this study, the Mk III Brånemark implant with an oxidised surface (TiUnite™ Nobel Biocare AB, Göteborg, Sweden) was compared to the classical machined Mk III Brånemark fixture.Materials and Methods: 35 patients with a mean age of 68 years and problematic mandibular dentures were treated. The primary complaints among the patients referred to the clinic for treatment related to poor retention of the mandibular denture, instability, denture sores and phonetic problems. Patients were initially placed randomly into the “machined surface” or “oxidised surface” group. A single implant was placed into the mandibular midline with high initial stability. A ball attachment was placed and the retentive cap incorporated into the existing denture. Reviews took place at 3,12 6 6 and 36 months. Clinical assessments, radiographs made with custom film holders, and stability measurements by both manual and resonance frequency analysis methods were recorded. All complications, failures, maintenance and reasons for dropout were noted. Visual analogue scale questionnaires were utilised to record patient satisfaction. (ANOVA p<.05) Results: Three out of 8 machined surface implants failed, representing an unacceptably high failure rate (37.5%). The machined surface was therefore discontinued for this study. Three oxidised surface implants did not achieve sufficient primary stability to be immediately loaded, so were treated with a two stage delayed loading protocol. The 25 immediately loaded oxidised surface implants were all classified as surviving at the 36-month recall. Patient satisfaction was very high with a significant increase in all comfort and functional parameters. Conclusions: Within the limitations of this study and research design, it appears that the immediately loaded single implant retained mandibular overdenture, using an oxidised implant surface in a small group of maladaptive patients, can provide a beneficial treatment outcome over a three year observation period. If insufficient stability at insertion is not achieved for immediate loading, then a delayed loading protocol should be utilised.

Resumo: Reabilitações na região posterior da maxila são geralmente confrontadas com atrofia óssea, associada à pneumatização do seio maxilar, impedindo a instalação de implantes de comprimento adequado. A cirurgia de elevação do seio maxilar foi introduzida na literatura em 1980, por Boyne & James, para permitir a instalação de implantes osseointegráveis nesta região, apresentando desde então algumas modificações que resultam em diferentes índices de sucesso e de complicações. Este estudo retrospectivo envolveu uma análise de 72 pacientes tratados em um período de 06 anos pela Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba - Unicamp. A amostra foi representada por um total de 91 seios maxilares, que receberam elevação associada a diferentes materiais de preenchimento para instalação de 101 implantes. Um total de 70 implantes (69,3%) foi instalado em um segundo procedimento cirúrgico, com um tempo médio decorrido desde a elevação de 9,88± 4,27 meses. Em 13 pacientes (18,5%) a reabilitação implanto-suportada foi abortada. Um total de 35 pacientes (48,61%) encontra-se em fase de reabilitação; 24 pacientes (33,33%) encontram-se reabilitados com próteses implanto-suportadas coroas unitárias, próteses fixas ou overdentures - com um tempo médio de acompanhamento de 25,54 ± 23,75 meses. O índice de sucesso neste período foi de 88,24%
Abstract: Rehabilitation of the posterior maxilla is often impaired by bone atrophy, associated with maxillary sinus pneumatization, preventing the installation of implants of ideal length. Maxillary sinus elevation was first introduced in the literature in 1980, by Boyne & James, as an attempt to allow the placement of osseointegrated implants in this region, and several modifications have been presented resulting in different success and complication rates. This retrospective study involved an analysis of 72 patients treated during a period of 6 years in the Oral and Maxillofacial Surgery Area, Piracicaba Dental School - Unicamp. The sample was represented by 91 maxillary sinuses that had been subjected to elevation associated with different grafting materiais, for the installation of 101 implants. In 13 patients (18.50%), implantsupported rehabilitation had been aborted; in 35 patients (48.61%), it had not been finished; 24 patients (33.33%) had already received rehabilitation with implant-supported prostheses unitary crowns, fixed prostheses or overdentures - with a mean follow-up period of 25.54 ± 23.75% months. The success rate in this period was 88.24%

Resumen
It was the aim of this 24-mo randomized controlled clinical trial to investigate whether the survival of a single median implant placed in the edentulous mandible to retain a complete denture is not compromised by immediate loading. Secondary outcomes were differences in prosthetic complications between the loading principles. Each of the 158 patients who received an implant was randomly assigned to the immediate loading group (n = 81) or the delayed loading group (n = 77). Recall visits were performed 1 mo after implant placement (for only the delayed loading group) and 1, 4, 12, and 24 mo after implant loading. Nine implants failed in the immediate loading group, all within the first 3 mo of implant loading, and 1 implant failed in the delayed loading group prior to loading. Noninferiority of implant survival of the immediate loading group, as compared with the delayed loading group, could not be shown (P = 0.81). Consistent with this result, a secondary analysis with Fisher exact test revealed that the observed difference in implant survival between the treatment groups was indeed statistically significant (P = 0.019). The most frequent prosthetic complications and maintenance interventions in the mandible were retention adjustments, denture fractures, pressure sores, and matrix exchanges. There was only 1 statistically significant difference between the groups regarding the parameter “fracture of the denture base in the ball attachment area” (P = 0.007). The results indicate that immediate loading of a single implant in the edentulous mandible reveals inferior survival than that of delayed loading and therefore should be considered only in exceptional cases (German Clinical Trials Register: DRKS00003730).

Resumen

 

Introduktion: Tandlöshet är ett problem som drabbar många människor. Kraven på funktionella och snygga tänder i livets alla skeden har blivit tydligare på senare år. Dentala implantat är en möjlighet att ersätta förlorade tänder och har hjälpt många individer att få sin livskvalité tillbaka.

Syfte: Att kartlägga mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat och vilka orsaker det finns till dessa.

Frågeställningar: Vad finns det för mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat?

Vad finns det för orsaker till komplikationer efter behandling med dentalt implantat?

Metod: Studien är en systematisk litteraturstudie.

Resultat: Efter behandling med dentalt implantat kan olika mjukvävnads- och hårdvävnadskomplikationer uppstå. De två vanligaste mjukvävnadskomplikationer var peri-implantär mukosit och mukosal hyperplasi. Typiska hårdvävnadskomplikationer som upptäcktes var benförlust och apikal peri-implantit. Tidigare parodontiterfarenhet visade sig vara den viktigaste orsaken till komplikationer vid dentala implantat.

Konklusion: Dental implantatbehandling är inte riskfri. Studien visade att komplikationer är vanliga efter dental implantatbehandling samt att det fanns riskfaktorer som påverkar dental implantatbehandling på ett negativt sätt.

Resumen
Introduction: Porcelain fractures belong to the most frequent technical complications in implant borne fixed restorations. Aim of this retrospective clinical study was to determine the prevalence and extent of porcelain fractures and to detect possible risk indicators. Methods: The study was designed by the Department of Prosthetic Dentistry, Dental School, University Hospital Carl Gustav Carus of Technical University of Dresden (TUD). Only adult patients (age ≥ 18 years) having previously received implant borne either metal-ceramic or all-ceramic fixed dental restorations from January 1995 until August 2011 were recruited. On the day of examination demographic and clinical parameters were systematically collected. Any present porcelain fracture was recorded systematically in terms of position and extent through clinical examination under relatively dry conditions. The fractures were classified in four categories according to their extent and respective reparability. Descriptive statistical analysis was conducted and contingency table analysis was used to determine the correlation between potential risk indicators and porcelain fractures on patient, restoration and unit level. Results: A total number of 144 patients (66 males, 78 females) was examined and entered the analysis. They represented 507 units (483 porcelain-fused-to-metal (PFM), 24 all-ceramic (AC)). Further these units represented 291 single crowns (SC)/ splinted crowns (S SC) (278 PFM, 13 AC) and 28 implant borne fixed dental prostheses (FDP) (28 PFM, 0 AC), 16 implant-tooth borne FDPs (14 PFM, 2 AC) and 14 implant borne cantilevered FDPs (13 PFM, 1 AC). The porcelain fracture rate on patient level was 23.6%, while on PFM FDP level this rate was 16.4%, on SC level was 12.2% and on unit level 9.5%. The results for AC restorations were 33.3%, 0.0% and 4.2% respectively. The parameters bruxism, age, gender, number of natural teeth, number of implants and implant supported FDPs per patient, former technical complication, implant system, opposing arch and splinted crowns or not had statistically significant correlation to porcelain fractures. Conclusion: Porcelain fracture in implant borne fixed restorations is a multicausal event. According to the limitations of the retrospective study design, this study showed that a male patient, bruxer, over 60-years-old, with ≤20 existing natural teeth, non-splinted crowns and former technical complications is prone to porcelain fracture. The results encourage further prospective clinical studies
Einführung: Unter den technischen Komplikationen bei festsitzenden implantatgetragenen Restaurationen zählen Verblendkeramikfrakturen zu den häufigsten. Ziel der vorliegenden klinischen retrospektiven Studie war die Bestimmung der Häufigkeit des Auftretens und Ausmaßes von Verblendkeramikfrakturen und möglicher Risikoindikatoren. Methode: Die Studie wurde in der Abteilung für Zahnärztliche Prothetik der UniversitätsZahnMedizin Carl Gustav Carus Dresden, Technische Universität Dresden (TUD) geplant und durchgeführt. Erwachsene Patienten (Alter ≥ 18 Jahre), die im Zeitraum von Januar 1995 bis August 2011 mit festsitzenden implantatgetragenen metall- oder vollkeramischen Restaurationen versorgt worden waren, wurden nachuntersucht. Dabei wurden demografische und klinische Parameter erhoben. Unter relativer Trockenlegung wurden alle Restaurationen systematisch auf Verblendkeramikfrakturen untersucht. Die Frakturen wurden in vier Gruppen je nach Ausmaß und Reparierbarkeit klassifiziert. Die Analyse der Daten erfolgte deskriptiv. Weiterhin erfolgte eine Kontingenztafelanalyse der Beziehungen zwischen den demografischen und klinischen Parametern und vorliegenden Verblendkeramikfrakturen auf Patienten-, Restaurations- und Einheitenebene. Ergebnisse: Eine Gesamtzahl von 144 Patienten wurde untersucht; 66 davon männlich und 78 weiblich. Es lagen 507 Einheiten (483 metallkeramisch/MK, 24 vollkeramisch/VK) vor, entsprechend 291 implantatgetragenen Einzelkronen/ verblockten Kronen (278 MK, 13 VK), 28 implantatgetragenen Brücken (28 MK, 0 VK), 16 Verbundbrücken (14 MK, 2 VK) und 14 implantatgetragenen Extensionsbrücken (13 MK, 1 VK). 23,6% der Patienten wiesen mindestens eine Verblendkeramikfraktur auf, wobei 16,4% der MK Brücken, 12,2% der MK Kronen und 9,5% der MK Einzeleinheiten betroffen waren. Die Ergebnisse für die VK Restorationen waren 33,3%, 0,0% und 4,2%. Es konnten Korrelationen zwischen den vorhandenen Veblendkeramikfrakturen und den Parametern Bruxismus, Alter des Patienten, Geschlecht, Anzahl der vorhandenen natürlichen Zähnen, Implantaten und implantatgetragenen Brücken pro Patient, frühere technische Komplikationen, Implantatsystem, Gegenkieferversrorgung und Verblockung der Einzelkronen ermittelt werden. Schlussfolgerung: Verblendkeramikfrakturen bei festsitzenden implantatgetragenen Restaurationen werden als multikausales Geschehen angesehen. Auf der Basis des vorliegenden retrospektiven Studiendesigns wurde ein männlicher Patient mit Bruxismus, über 60 Jahre alt, mit ≤20 vorhandenen natürlichen Zähnen, nicht verblockten Kronen und früheren technischen Komplikationen als Risikopatient für Verblendkeramikfrakturen identifiziert. Die Ergebnisse geben Anlass zu weiteren prospektiven klinischen Studien

Resumen
Rehabilitation of edentulous patients with Implant-supported Complete Fixed Dental Prosthesis (ICFDP) is a well-documented treatment option. This dissertation assessed the relation between the rate of biological/mechanical complications and the type of metal framework alloy, length of cantilever extension. The results showed that long-term clinical outcomes of ICFDP were favorable. While 30% of patients experienced biological complications, 66.6% of the prostheses needed to be repaired during follow-up period. The risk of prosthesis failure and mechanical complications was significantly higher in silver-palladium frameworks as compared with palladium-silver or type IV gold alloys. The length of cantilever was not correlated with the amount of marginal bone loss. The rate of marginal bone loss around anterior implants was higher than that of posterior implants associated with cantilever segments. The treatment improved the patients’ quality of life and 96% of patients would undergo the same treatment again if required.

Resumen
Short dental implants are commonly recommended to be implemented with small crown-to-implant (C/I) ratios due to their mechanical stability — decreasing C/I ratios cause less deformation in skeletal tissue under occlusal force. However, the long-term stability of short implants with high C/I ratios remains a controversial issue due to biomechanical complications. This study evaluates the strain distribution and functional implications in an implant-supported crown with various C/I ratios using a high-fidelity, nonlinear finite-element model. Several clinical scenarios are simulated by loading implants with various implant lengths (IL) and crown heights (CH). Strain distribution and maximum equivalent strain are analyzed to evaluate the effects and significance of CH, IL, and the C/I ratio. The study shows underloading for certain implant configurations with high C/I ratio. Increasing IL and decreasing C/I in moderation demonstrates a positive effect in long-term stability.

Resumen
Bruxism is a nonfunctional motor activity that is characterized by grinding and clenching of the teeth. It has been postulated that bruxism causes excessive occlusal load on the dental implant and its superstructures leading to biological and biomechanical complications. While many researchers suggest that grinding/clenching causes early implant complications and accelerated bone loss, others indicate that the long term effects are still unclear. The goal of this study is to analyze the effect of bruxism loading condition on the stress distribution of an implant supported overdenture (ISO) using finite element analysis (FEA) and compare the results with one of the most functionally efficient occlusion schemes in the clinical dentistry — lingualized occlusion. A high fidelity solid model of a mandibular denture encompassing lingual and buccal cusps, mesial and distal fossae supported by four implants and a connecting titanium prosthetic bar, resting on alveolar bone were modeled in SolidWorks 2013 following proper clinical guidelines and imported to ANSYS 15.0 for stress analysis. The results of the study demonstrate that the stress distribution in the implant prostheses and surrounding bone is significantly affected due to bruxism as compared to the lingualized loading. While the location of the maximum stress concentration was the same (neck of the posterior implants) for both loading conditions, there was an increase of approximately 115% von-Mises stress for bruxism loading condition as compared to the lingualized occlusion. The maximum principal stress in the cortical bone surpassed the ultimate tensile strength limit of the jaw bone implying possibility of bone resorption in the peri-implant area.
