Previous issue date: 2012-12-13 / The evaluation criteria of the cases treated with dental implants are based on clinical
and radiographic tests. In this context it is important to conduct research to determine
prognosis of different types of prosthetic rehabilitation and determination of the main
problems affecting this type of treatment. Thus, the objective of this study was to assess the
prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this
cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The
failures were observed by clinical and radiographic examination. The results showed that the
fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent.
The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of
resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%)
had a higher occurrence. The failure of adaptation between the abutment and the implant
(6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence
and, when related to other parameters showed a significant association, particularly with the
cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of
failures, protocols must be observed from diagnosis to the settlement and control of
prostheses on implants, particularly with respect to technical steps of the making of the
prosthesis and care in radiographic evaluating the fit between their components / Os crit?rios de avalia??o dos casos tratados com implantes osseointegrados s?o
baseados em testes cl?nicos e exames radiogr?ficos. Nesse contexto, ? importante a realiza??o
de pesquisas na determina??o do progn?stico dos diferentes tipos de reabilita??es prot?ticas e
na determina??o dos principais problemas que atingem este tipo de tratamento. Desta forma, o
objetivo deste trabalho foi avaliar as condi??es prot?ticas de indiv?duos reabilitados com
implantes osseointegrados e pr?teses sobre implantes. Neste estudo transversal foram
atendidos 153 pacientes, contabilizando uma amostra de 509 implantes. As falhas foram
observadas atrav?s do exame cl?nico e radiogr?fico. Os resultados demonstraram que a fratura
(0,2%), a perda (0,4%) e o afrouxamento dos parafusos (3,3%) foram as falhas menos
frequentes. A fratura das estruturas como a resina (12,4%), porcelana (5,5%) e met?lica
(1,5%), a perda da resina que recobre o parafuso de fixa??o (23,8%) e a perda de reten??o nas
pr?teses overdentures (18,6%), tiveram uma ocorr?ncia maior. A falha de adapta??o, entre o
pilar e o implante (6,9%) e principalmente entre a pr?tese e o pilar (25,4%) teve uma alta
preval?ncia e, quando relacionada com outros par?metros, demonstrou uma associa??o
significativa, principalmente com a fixa??o do tipo cimentada (OR= 5,39). Pode-se concluir
que para minimizar o aparecimento de falhas, protocolos devem ser observados desde o
diagn?stico at? o assentamento e controle das pr?teses sobre implantes, principalmente com
rela??o aos passos t?cnicos da confec??o da pr?tese e com o cuidado em avaliar
radiograficamente a adapta??o entre seus componentes
