Conventional and digital maxillary occlusal record for the manufacture of complete-arch implant-supported fixed prostheses: randomized controlled clinical trial.

OBJECTIVES: To evaluate the trueness of the digital maxillary occlusal records in comparison with the conventional records for the fabrication of complete-arch implant-supported fixed prostheses. MATERIALS AND METHODS: This randomized controlled clinical trial followed the recommendations of the CONSORT statement. Twenty participants who used a mandibular interim complete-arch fixed prosthesis and conventional complete maxillary dentures were included in the study. The participants were randomized into two types of maxillary occlusal records: conventional (COR) and digital (DOR) (TRIOS; Shape A/S). After fabricating the prostheses, the distribution and number of occlusal contact points, and the time taken to obtain the maxillary occlusal record and work model were evaluated. Descriptive analysis was used to evaluate the distribution of occlusal contact points. The Wilcoxon test was employed for assessing the number of occlusal contact points, while the Mann-Whitney U test was used for the time taken to obtain the working casts and the maxillary occlusal record and occlusal adjustment times (p < 0.05). RESULTS: There was a similarity in the jaw relation recording methods regarding the distribution of occlusal contact points. There was no difference in the number of occlusal contact points between the anterior (p = 0.439) and posterior (p = 0.227) teeth. No relationship was observed between the distribution and number of occlusal contact points (COR, p = 0.288; DOR, p = 0.183). DOR required less occlusal and clinical adjustment time, on the other hand more laboratory and total workflow time than COR (p < 0.001). CONCLUSION: The DOR may be an option for obtaining the functional space necessary for the assembly of teeth in complete-arch implant-supported fixed prostheses; however, it requires more working time. CLINICAL RELEVANCE: The digital occlusal recording method can be used to assess the interocclusal space for the virtual tooth setup of a complete-arch implant-supported fixed prosthesis.

Are bodybuilding and cross-training practices dangerous for promoting orofacial injuries? A scoping review.

Bodybuilding and cross-training exercises bring health benefits. However, orofacial injuries can occur during practice. This study aimed to map, analyze, interpret, and synthesize data from studies on the main orofacial injuries resulting from bodybuilding and cross-training practices. This scoping review followed the Joanna Briggs Institute and PRISMA-ScR methods, with high-sensitivity searches in PubMed, Web of Science, Scopus, ScienceDirect, Embase, Virtual Health Library and the Google Scholar. Original scientific articles published up to May 2024 were included, which evaluated the presence of self-reported or professionally diagnosed orofacial injuries by bodybuilding and cross-training practitioners aged 18 years or older. Literature reviews, editorials, and guidelines were excluded. Tables and figures were used to map and summarize the results. Out of 30.485 potentially eligible articles, four were included. The main orofacial injuries identified in both bodybuilding and cross-training practitioners were dental damage (n = 4), temporomandibular joint (TMJ) disorders (n = 3), and traumas to oral soft tissues (n = 2) and facial soft tissues (n = 2). Dental damage and TMJ disorders were the most prevalent conditions among bodybuilding and cross-training practitioners. Therefore, dental damage and TMJ disorders were the most prevalent conditions among bodybuilding and cross-training practitioners. However, further prospective studies with more in-depth methodological designs and fewer biases are necessary.

Addition of substances to reduce the erosive potential of acidic beverages to tooth enamel: A scoping review.

OBJECTIVE: This scoping review aimed (1) to map, analyse, interpret and synthesize data from in situ studies on which substances were added to acidic beverages to reduce the erosive potential on tooth enamel and (2) to establish the level of evidence of the effectiveness of adding substances to acidic beverages to reduce the erosive potential on tooth enamel. DESIGN: This is a scoping review, according to the methods from the Joanna Briggs Institute and PRISMA-ScR, with high-sensitivity searches in the databases PubMed (MEDLINE), Virtual Health Library, Embase (Elsevier), Scopus (Elsevier), Web of Science and ScienceDirect (Elsevier). In situ studies published in English until December 2022 were included. Studies that did not report a control group were excluded. To map and summarize the results, tables and figures were used. RESULTS: From 895 potentially eligible articles, nine were included. Blackcurrant juices (n = 5) with the addition of calcium (n = 3) or xanthan gum (n = 2) formulations were the most tested in terms of reducing the erosive potential of the beverages on tooth enamel. The profilometer was the equipment of choice (n = 8) for evaluating the loss of enamel structure after the experimental tests. CONCLUSIONS: Calcium and xanthan gum are among the most tested by in situ studies, offering promising results in reducing the erosive potential of fruit juices and carbonated and energy drinks.

Device trueness in passivity and misfit of CAD-CAM frameworks: Conventional versus printed casts.

STATEMENT OF PROBLEM: Obtaining a passive and well-adapted framework is challenging when intraoral scanning edentulous arches with multiple implants. The trueness of the printed casts is unclear. PURPOSE: The purpose of this clinical study was to evaluate the trueness of frameworks made from conventional and printed casts regarding clinical passivity and misfit. MATERIAL AND METHODS: Ten participants with complete mandibular fixed implant-supported interim prostheses retained by 4 implants were included. Each participant had a conventional impression and a digital scan made. The digital scan was made using an innovative device. Both conventional and digital casts were made, and the virtual images were used for milling the digital framework in cobalt chromium alloy. All frameworks were evaluated for passivity and marginal vertical misfit with the single screw test, with 4 attempts consisting of the tightened screw position, a test with all screws tightened, and an interspersed tightening test. The Kruskal-Wallis test was used to evaluate the trueness of the tested device for framework construction through the single screw test on vertical marginal misfit in the conventional and printed groups (α=.008). The Friedman test was used to assess the effect of test type (α=.05), and the Wilcoxon test was used to identify group-to-group differences (α=.017). RESULTS: The absence of space between the framework and the abutments and interferences during its placement, as well as good stability, were observed clinically. In laboratory analysis, greater framework misfits were observed in the printed group compared with the conventional group when the single screw test was applied. Comparing the 3 tests used, the greatest misfits were observed when the framework was screwed onto the printed cast. CONCLUSIONS: The innovative device tested for the intraoral scanning of multiple implants had clinically acceptable accuracy for the construction of passive and adapted frameworks. The conventional cast was more accurate than the printed cast, with lower misfit values, in all tests.

Accuracy and reproducibility of real and virtual occlusal contact points in implant-supported fixed prostheses.

AIM: To evaluate the accuracy and reproducibility of real and virtual occlusal contact points in implant-supported, fixed complete dentures. MATERIALS AND METHODS: The study included 19 participants using mandibular interim complete-arch fixed prosthesis supported by 3 or 4 implants as opposed to conventional removable complete dentures. At installation, an examiner installed the prostheses and verified the occlusal contact points through 2 methods: recording the real contact points with carbon paper (RC) followed by occlusal photography and intraoral scanning (VC) to record the virtual contact points to obtain a screen print of the software. Then, the two images were randomized to determine the order to be inserted into Microsoft PowerPoint for blind and paired evaluation. The independent variables consisted of the distribution of occlusal contacts points (qualification through pre-defined scores based on the position of the contact points on the surfaces of the teeth) and the reproducibility of the methods by verifying the number of occlusal points. For this, a descriptive analysis was used to evaluate the distribution of occlusal contacts points and the Wilcoxon test for the reproducibility of the occlusal contact points between the methods (p<0.05). RESULTS: The methods had 100% and 73.6% real and virtual occlusal contact points, respectively, which is considered clinically excellent. There was no significant difference regarding the reproducibility of the methods by the number of occlusal contact points (RC: x̅13.32; VC: x̅13.68; p=0.715). CONCLUSION: The use of the tested intraoral scanner can be an easy and fast tool for studying and mapping the occlusion, and storing data for future treatment, with the conventional method being the preferred method for performing the occlusal adjustment.

Technical Quality of Complete Dentures: Influence on Masticatory Efficiency and Quality of Life.

PURPOSE: To evaluate the effect of the technical quality of conventional complete dentures (CD) on masticatory efficiency and quality of life (QoL) of denture wearers during a 1-year follow-up. MATERIALS AND METHODS: A prospective clinical trial with 32 edentulous patients (mean age of 60.2 years) wearing mandibular and maxillary dentures was conducted. All patients were evaluated wearing their preexisting dentures and after 3, 6, and 12 months postinsertion of new dentures. A reproducible method for objective evaluation of the technical quality of CDs was employed. Masticatory efficiency was evaluated by the colorimetric method using beads as artificial testing food. The oral health impact on patient QoL was measured using the OHIP-EDENT (Oral Health Impact Profile in Edentulous Adults) questionnaire. The nonparametric Wilcoxon test was applied to reveal any differences in technical quality between the preexisting and new dentures. The Friedman test was used to detect differences in masticatory efficiency and oral health impact on QoL. Spearman's correlation was applied to reveal correlation between the variables. RESULTS: Comparing preexisting and new dentures, significant improvement was found in technical quality between the dentures (p < 0.001). There was no statistically significant difference in masticatory efficiency. A significant decrease was found in the total OHIP-EDENT scores after denture replacement. A positive correlation was found between technical quality and OHIP in the new denture wearers (p = 0.011). CONCLUSIONS: According to the results of this study, denture quality significantly improved patients' oral health-related QoL; however, insertion of new dentures did not influence masticatory efficiency.

Effect of cantilever extension on bone loss in mandibular complete-arch implant-supported fixed prosthesis about 3 and 4 implants.

STATEMENT OF PROBLEM: The assessment of bone loss around implants has been widely studied, but the effect of cantilever length as a risk factor is not fully understood. PURPOSE: The objective of this randomized controlled clinical trial was to compare the peri-implant bone loss of mandibular complete-arch implant-supported fixed prosthesis supported (FPS) by 3 and 4 implants and to correlate with the size of the horizontal and vertical distal cantilever at prosthesis installation (T1) and after one year (T2). MATERIALS AND METHODS: 72 external hexagon (EH) type implants were installed in 20 participants. Of these, 24 support FPS with 3 implants (GI3) and 48 with 4 implants (GI4). The inferior implants were named 1, 2, 3, and 4 according to their location in the mandibular arch, in a clockwise direction. Digital periapical radiographs were taken at times T1 and T2 for analysis and measurement of peri-implant bone loss. The horizontal and vertical distal cantilevers were measured with a digital caliper and correlated with peri-implant bone loss. RESULTS: The survival rate of implants in GI3 was 91.66%, in GI4 it was 97.91%. The mean bone loss in GI3 was 0.88 (± 0.89) mm and in GI4 it was 0.58 (± 0.78) mm (P = 0.225). There was no correlation between distal horizontal cantilevers and bone loss in the studied groups, with GI3 being -0.25 (P=0.197) and GI4-0.22 (0.129). Larger vertical cantilevers of implants 1 (P=0.018), 3 (P=0.015) and 4 (P=0.045) correlated with greater bone loss in GI4. CONCLUSION: The number of implants in FPS did not influence peri-implant bone loss after 1 year of follow-up. Larger vertical cantilevers influenced greater bone loss in complete-arch implant-supported fixed prosthesis supported by 4 implants. Int J Prosthodont. 10.11607/ijp.8347.

Use of impression technique to identify areas of super compression before installation of new complete dentures: a randomized double-blind trial.

OBJECTIVE: To identify pressure areas using an impression technique and to evaluate whether adjustment of dentures prior to installation can decrease ulcer frequency, number of adjustments, and improve satisfaction with treatment. MATERIALS AND METHODS: Fifty complete denture users were selected and randomly divided into two groups. Pressure areas were identified in 25 subjects using the impression technique with fluid silicone, and the denture base in these areas was adjusted before installation. A total of 25 subjects received new complete dentures without adjustments before installation. The number of ulcers observed was registered at 1, 7, 15, and 30 days after installation. Patient satisfaction was collected before and 1 month after the installation. The number of necessary post-installation adjustments was considered. Comparisons between the groups with respect to the number of ulcers, adjustments, and patient satisfaction were performed using the Mann-Whitney test. RESULTS: Identification of pressure areas reduced the number of ulcers after installation of the new prostheses. These results were observed in the 1- (p = 0.004) and 7-day (p = 0.002) adjustments for the maxilla and in all the adjustments for the mandible. The technique improved patient satisfaction (p = 0.031) and reduced the number of post-installation adjustments (p ≤ 0.001). CONCLUSION: A reduction in the incidence of ulcers, number of adjustments and improvement in patient satisfaction could be observed with the use of the technique.

Lesões orofaciais em mulheres vítimas de violência não fatal: uma revisão integrativa / Orofacial injuries in women victims of non-fatal violence: an integrative review

Introdução: Grande proporção dos atos violentos praticados contra as mulheres resulta em lesões maxilofaciais. A região facial é o local mais recorrente das violências físicas, uma vez que o violentador deseja evidenciar a fragilidade da vítima e distanciá-la socialmente, causando danos psicológicos, estéticos e morais. Objetivo: Analisar as regiões craniofaciais mais afetadas e o perfil das mulheres que sofreram violência não fatal. Método: Trata-se de uma revisão integrativa da literatura, com identificação de artigos nas bases SciELO, MEDLINE via PubMed, LILACS e BBO, usando os descritores "violência doméstica", "injúria facial", "traumatismo facial" e suas variantes nos idiomas inglês e português. Resultados: Foram selecionados 14 estudos. A idade das mulheres variou de 16 a 64 anos, com a maioria tendo ocupações domésticas e dependência financeira do cônjuge ou parceiro. Todos os estudos abordavam a região de cabeça e pescoço como o local mais acometido por lesões, por se tratar de uma região vulnerável. A órbita foi considerada a estrutura anatômica mais acometida mencionada em quatro estudos, seguida por boca, nariz e mandíbula. Hematomas e equimoses foram as lesões mais encontradas, identificadas em 9 estudos. Além disso, 13 estudos relataram o uso de instrumento contundente durante as agressões. Outras lesões como fraturas dentais, avulsão dentária, fraturas faciais e edema foram encontradas com menos frequência. Conclusão: O terço superior da face foi o mais atingido, em especial a órbita, e o tipo de injúria mais comum foram as equimoses e hematomas geralmente provocados pelos parceiros.

Introduction: A large proportion of violent acts against women result in maxillofacial injuries. The facial region is the most recurrent site of physical violence because the abuser wishes to highlight the victim's frailty and distance it socially, causing psychological, aesthetic and moral damage. Objective: To analyze the most affected craniofacial regions and the profile of women who have suffered non-fatal violence. Method: This is an integrative literature review, with identification of articles in SciELO, MEDLINE/ PubMed, LILACS and BBO, using the keywords "domestic violence", "facial injury", "facial trauma" and its variants in English and Portuguese. Results: 14 studies were selected. The age of the women ranged from 16 to 64 years, with the majority having domestic occupations and financial dependence on their spouse or partner. All studies mentioned the head and neck region as the location most affected by injuries, as it is a vulnerable region. The orbit was the most affected anatomical structure mentioned in four studies, followed by the mouth, nose and mandible. Bruises were the most frequently found lesions, identified in nine studies. In addition, 13 studies reported the use of a blunt instrument during attacks. Other injuries such as dental fractures, tooth avulsion, facial fractures and edema were found less frequently. Conclusion: The upper third of the face was the most affected, especially the orbit, and the most common type of injury was bruises usually caused by partners

Masticatory efficiency, quality of life, comfort, retention and satisfaction on digital denture: case report / Eficiência masticatória, qualidade de vida, conforto, retenção e satisfação com prótese total digital: caso clínico

ABSTRACT The aim of this study was to describe a clinical protocol for fabrication of maxillary and mandibular dentures using CAD/CAM technology. Further, digital and conventional dentures fabricated for the same patient were compared. The comparison was based on patient's satisfaction, comfort, retention, number of follow-up sessions, masticatory performance and quality of life. No laboratorial step was needed for CAD/CAM fabrication and less sessions were required up to denture insertion. Compared to the conventional dentures, digital dentures provided better satisfaction, comfort and retention and required less follow-up sessions. Both dentures presented similar results about masticatory performance and quality of life. As a conclusion, digital denture is a viable treatment alternative for edentulous patients. However, controlled and randomized clinical trials are required to reveal the real benefits of this treatment alternative compared to the conventional denture.

RESUMO O objetivo deste estudo foi descrever um protocolo clínico para a fabricação de próteses superiores e inferiores usando a tecnologia CAD/CAM. Além disso, as próteses digitais e convencionais fabricadas para o mesmo paciente foram comparadas. A comparação foi baseada na satisfação, conforto, retenção, número de sessões de acompanhamento, desempenho mastigatório e qualidade de vida do paciente. Nenhuma etapa laboratorial foi necessária para a fabricação de CAD/CAM e menos sessões foram necessárias até a inserção da prótese. Comparadas às próteses convencionais, as próteses digitais proporcionavam melhor satisfação, conforto e retenção e exigiam menos sessões de acompanhamento. Ambas as próteses apresentaram resultados semelhantes sobre desempenho mastigatório e qualidade de vida. Como conclusão, a prótese digital é uma alternativa viável para o tratamento de pacientes desdentados. No entanto, ensaios clínicos controlados e randomizados são necessários para revelar os benefícios reais dessa alternativa de tratamento em comparação com a prótese convencional.

Classification of Patients by Occlusal Condition

ABSTRACT Objective: To propose a classification of patients by occlusal condition and its apparent validation. Material and Methods: This cross-sectional analytical study was divided into two phases. In the first, a trained examiner divided the patients into four groups according to the proposed classification of this design: Type 1 patient - completely dentate individuals; Type 2 - partially edentulous individuals with occlusal stability; Type 3 - partially edentulous individuals with no occlusal stability; Type 4 - completely edentulous individuals. In this phase, 122 patients were analyzed with an instrument developed for this experiment. Results: All patients in the sample of this research were classified in some division of the proposed instrument. In the second phase, the apparent validation of the classification was conducted by three judges, who obtained an excellent agreement with the allocation of patients in one of the types according to the indication of the first examiner (Kappa = 85%). Conclusion: It is evident that the classification presents reliability, ease of visualization, good conditions for interprofessional communication, and it can be used in dental clinical practice to assist in the study and integrated planning of clinical cases.

Duplicação rápida de prótese total: passo-a-passo / Rapid doubling of dentures: step-by-step

O presente trabalho descreve uma técnica simples, rápida e de baixo custo para confecção de próteses totaisconvencionais novas a partir da duplicação de próteses antigas, em uso pelo paciente. Os moldes obtidos pormeio da duplicação das próteses devem ser preenchidos com resina acrílica incolor. As réplicas das prótesesobtidas serão usadas para moldagem funcional com poliéter, estabilizadas com registro oclusal em resina acrílica.Os moldes devem ser vazados e montados em articulador semi-ajustável. Os dentes artificiais são posicionados com auxílio de um guia feito em silicona de condensação para reproduzir o posicionamento dos dentes da prótese antiga e fixados com cera 7. Após aprovação dos dentes na prova dos dentes em cera, sem necessidade de ajuste dos planos de orientação, as próteses poderão ser acrilizadas e após o ajuste oclusal no articulador as mesmas poderão ser instaladas

This study presents a simple, fast and low cost technique for fabrication new conventional dentures from theduplication of old prosthesis in use by the patient. Colorless acrylic resin was poured into the moulds obtained byduplication of prosthesis. With the replicas obtained a functional impressions using polyether should be performed and they are stabilized with occlusal registration in acrylic resin. The molds need to be castings and mounted on an semi-adjustable articulator. The artificial teeth are positioned with the assistance of a guide made condensation silicone to reproduce the positioning of the teeth of the old prosthesis and fixed with wax 7. After approval of the teeth on the trial in wax, without adjustment of the planes, the prosthesis may be processed in the laboratory. After occlusal adjustment in the articulator the same can be installed

Prótese total mandibular sobre implantes: fatores que influenciam no sucesso da reabilitação / Total mandibular prosthesis on implants: factors that influence the success of rehabilitation

Objetivo: Objetivou-se avaliar um conjunto de fatores que podem interferir no sucesso da reabilitação total no arco inferior por meio da análise da qualidade de vida relacionada à saúde oral, performance mastigatória, complicações e saúde peri-implantar (tecidos moles e duros) de pacientes tratados com próteses totais removíveis ou fixas sobre implantes opostas a próteses totais convencionais. Materiais e métodos: Foram avaliados o impacto da saúde oral na qualidade de vida (OHIP-EDENT), performance mastigatória (PM) (método granulométrico ­ identificação de X50), ocorrência de complicações protéticas e a saúde dos tecidos periimplantares de pacientes com sobredentaduras sobre 2 implantes com sistema barra clipe (GS) ou com próteses totais fixas sobre 4 ou 5 implantes (GF), mandibulares, opostas a prótese total convencional. Os tecidos peri-implantares foram avaliados quanto a presença de biofilme no minipilar (BMP), profundidade de sondagem (PS), sangramento à sondagem, presença de inflamação, altura da faixa de mucosa queratinizada (MQ), nível da margem da mucosa (NMM) e perda óssea (PO). Os tempos de seguimento foram 3 (T1) e 12 (T2) meses e 2 (T3), 3 (T4) e 4 anos (T5) após a reabilitação. Para análise das diferenças estatísticas em cada grupo e ao longo do tempo foram utilizados os testes Mann-Whitney, Wilcoxon e Friedman, com nível de significância de 5%. Resultados: A amostra contou com 39 pacientes com idade média de 63,90 anos (± 8,39). Os resultados mostraram que os valores médios do OHIP total de todos os pacientes aumentaram mudando de 5, para 6,60 e 6,71, em 2 (n=33), 3 (n=30) e 4 anos (n=28). Nesses tempos o mesmo aconteceu com o X50 que aumentou de 5,68 mm para 6,25mm e 6,33mm. Em T4, o GS sofreu maior impacto negativo da saúde oral na qualidade de vida no quesito disfunção física (p=0,019). Os pacientes com sobredentadura experimentaram uma piora da PM ao longo do tempo (p=0,001). Em relação às complicações, destaca-se que em GS há 2,28 vezes mais chances de ocorrerem complicações. A presença de BMP aumentou ao longo do tempo no grupo com prótese fixa (p=0,042) e foi maior nesse grupo do que no GS a partir do primeiro ano de uso da prótese (p<0,05). Os valores de PS aumentaram em GS ao longo do tempo (p<0,001). O sangramento à sondagem foi maior no GF do que no GS em T3 e T4 (p<0,05) e o NMM se manteve negativo no GF em todos os tempos (p<0,05), indicando maior risco de exposição de roscas do implante nesse grupo. A perda óssea ao longo do tempo aumentou entre os pacientes com prótese fixa (p<0,001) e foi maior do que a observada no grupo com sobredentadura em 2, 3 e 4 anos (p<0,05). Conclusões: Concluiu-se que ambos os tratamentos se assemelham quanto ao impacto sobre a qualidade de vida e performance mastigatória, no entanto, os pacientes reabilitados com sobredentaduras possuem maior propensão à ocorrência de falhas protéticas. Enquanto os pacientes reabilitados com prótese fixa apresentaram condições dos tecidos peri-implantares menos favoráveis (AU).

Objective: The objective of this study was to evaluate a set of factors that may interfere in the success of total rehabilitation in the lower arch through the analysis of the quality of life related to oral health, masticatory performance, complications and peri-implant health (soft and hard tissues) with total removable or fixed prostheses on implants opposed to conventional complete dentures. Materials and methods: Oral health-related quality of life using the Oral Health Impact Profile for edentulous (OHIP-EDENT), masticatory performance (PM) (granulometric method - identification of X50), occurrence of prosthetic complications and peri-implant tissues health in patients wearing mandibular overdenture on 2 implants with bar-clip attachment system (GO) or with mandibular fixed total dentures on 4 or 5 implants (GF). The peri-implant tissues were evaluated for plaque index in the mini-abutment (PI), probing depth (PD), bleeding index, presence of peri-implant inflammation, keratinized mucosa zone, marginal mucosa level (MML) and bone loss (BL). Follow-up times were 3 (T1) and 12 (T2) months and 2 (T3), 3 (T4) and 4 years (T5) after rehabilitation. For analysis of the statistical differences in each group and over time the Mann-Whitney, Wilcoxon and Friedman tests were used, with a significance level of 5%. Results: The sample consisted of 39 patients with a mean age of 63.90 years (± 8.39). The results showed that mean values of total OHIP for all patients increased from 5 to 6.60 and 6.71 in 2 (n = 33), 3 (n = 30) and 4 years (n = 28). In these times the same thing happened with the X50 that increased from 5.68 mm to 6.25 mm and 6.33 mm. In T4, GO had a greater negative impact of oral health on quality of life in the physical dysfunction domain (p = 0.019). Overdenture patients experienced worsening of PM over time (p = 0.001). Regarding the complications, GO there are 2.28 more times chances of complications occurring. The PI increased over time in the fixed prosthesis group (p = 0.042) and was higher in this group than in the GO from the first year of use of the prosthesis (p <0.05). The PS values increased in GO over time (p <0.001). Bleeding was higher in GF than in GO in T3 and T4 (p <0.05) and MML remained negative in GF at all times (p <0.05), indicating a higher risk of exposure of implant threads in this group. Bone loss over time increased among patients with fixed prosthesis (p <0.001) and was greater than that observed in the overdenture group at 2, 3 and 4 years (p <0.05). Conclusions: It was concluded that both treatments resemble the impact on quality of life and masticatory performance, however, patients rehabilitated with overdentures are more propensity to the occurrence of prosthetic failures. While patients who were rehabilitated with fixed prosthesis had less favorable peri-implant tissue conditions (AU).

Falhas e complicações com o uso de prótese parcial removível inferior de extremidade livre bilateral / Failures and complications with the use of removable partial dentures bilateral free end

Objetivo: Verificar a frequência e tipo de complicações relacionadas à prótese parcial removível (PPR) inferior, classe I de Kennedy, ao longo do tempo. Materiais e Métodos: Este estudo observacional foi composto por uma amostra de 65 usuários de PPR inferior em arcos Classe I de Kennedy e prótese total superior, reabilitados no Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN). Os pacientes foram acompanhados por meio de controles periódicos nos períodos de 60 dias, 6 meses e 1 ano desde a instalação. Após o primeiro ano de controle os demais retornos tiveram periodicidade anual. A ocorrência de complicações ou falhas protéticas foi observada e registrada em ficha clínica específica ao longo de 39 meses. Os padrões de falhas observados foram enquadrados nas seguintes situações: ocorrência de úlceras traumáticas depois de 2 meses de instalação, ausência de retenção, fratura de nicho ou cárie sob o nicho, fratura ou descolamento dos dentes artificiais, fratura do conector maior, fratura de grampo, fratura do apoio, suporte deficiente (necessidade de reembasamento da prótese) e fratura da prótese. Resultados: A ocorrência de complicações apresentou baixa frequência, sendo maior a partir do segundo ano de uso da prótese. Dentre as complicações que mais aconteceram está a perda de retenção (31,57%). Falhas de maior gravidade e de difícil resolução como a fratura de elementos da estrutura metálica da PPR tiveram baixa ocorrência e foram representadas por apenas um caso de fratura do conector maior (5,3%). Conclusão: Próteses parciais removíveis de extremidade livre mandibulares opostas a próteses totais convencionais apresentam baixo índice de complicações após 39 meses de uso quando submetidas a controles periódicos. (AU)

Aim: To determine the frequency and type of complications related to removable partial denture (RPD) less, Kennedy Class I, over time . Materials and Methods: This observational study consisted of a sample of 65 users PPR lower arches in Kennedy Class I and dentures, rehabilitated in the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). Patients were followed through periodic controls during periods of 60 days, 6 months and 1 year from installation. After the first year of control had other returns annually. The occurrence of complications or prosthetic failure was observed and recorded in a specific clinical record over 39 months. The patterns of failures observed were classified in the following situations: occurrence of traumatic ulcers after 2 months of installation, lack of retention, fracture or caries in the rest, fracture or dislocation of the artificial teeth, the larger connector fracture, fracture clip fracture support, poor support (need to reline the denture) and prosthesis fracture. Results: The incidence of complications was low frequency, being higher in the second year of use of the prosthesis. Among the complications that occurred more is the loss of retention (31.57%). Failures more severe and difficult to solve as the fracture elements of the metal structure of the PPR had low occurrence and were represented by only one case of the larger connector (5.3%) fractures. Conclusion: Removable partial dentures mandibular free end opposing of the conventional dentures have a low complication rate after 39 months of use when subjected to periodic controls. (AU)
