Introdução: A confeção de restaurações cerâmicas por via CAD/CAM é uma realidade cada vez mais abrangente na área da Medicina Dentária. Com o desenvolvimento tecnológico e o aparecimento de cerâmicas melhoradas, a realização de restaurações estéticas parece ter vindo a ser facilitada para o clínico. A adaptação marginal é um dos principais alvos do sucesso de uma reabilitação fixa e neste sentido, torna-se importante conhecer quais os fatores de envolvência clínica, inerentes à confeção de restaurações cerâmicas com sistemas CAD/CAM, que a podem influenciar. Objetivo: Realizar uma revisão da literatura atual, visando responder à questão PICO: “Na reabilitação de peças e/ou ausências dentárias com restaurações cerâmicas fixas, confecionadas com tecnologia CAD/CAM, quais os fatores de escolha clínica que podem influenciar a adaptação marginal?” Materiais e Métodos: Foi efetuada uma pesquisa na base de dados primária MEDLINE, por artigos em inglês e publicados desde 2006, com a seguinte sequência de palavras-chave: cad cam AND ceramic AND marginal AND (adaptation OR fit OR gap OR discrepancy) AND (fixed OR crown OR bridge) NOT implants. Dos 200 artigos obtidos, foram incluídos 49 nesta dissertação. Resultados: 11 estudos avaliaram o desenho do preparo, 13 a técnica de digitalização, 11 o material cerâmico, 19 o sistema CAD/CAM utilizado e 5 a cimentação. Dez destes artigos abordam múltiplos fatores, pelo que se encontram repetidos nesta descrição. Conclusões: Todos os fatores avaliados parecem ter alguma influência na adaptação marginal de restaurações cerâmicas confecionadas com tecnologia CAD/CAM, contudo a diversidade de protocolos adotados nos diferentes estudos limita a sua comparação. Em estudos futuros, é necessário que haja uma maior padronização para que se possam retirar conclusões mais fidedignas do ponto de vista de evidência científica.
Introduction: The manufacture of ceramic restorations with CAD / CAM systems is an increasingly wide reality in Dentistry. With the technological development and the appearance of improved ceramics, the accomplishment of esthetic restorations seems to have been facilitated for the clinician. The marginal fit is one of the main predictors of a fixed rehabilitation success, thus, it is important to know which clinical factors, involved in the production of CAD / CAM ceramic restorations, can have an influence in it. Objective: To carry out a review of the current literature, in order to answer the PICO question: "In the rehabilitation of dental pieces and/or absences with fixed ceramic restorations, fabricated with CAD / CAM technology, which factors, of clinical choice, can influence the marginal adaptation?" Materials and Methods: A search was performed in the MEDLINE primary database for articles in English and published since 2006, with the following sequence of keywords: cad cam AND ceramic AND marginal AND (adaptation OR fit OR gap OR discrepancy) AND (fixed OR crown OR bridge) NOT implants. Of the 200 articles obtained, 49 were included in this dissertation. Results: 11 studies evaluated the design of the preparation, 13 the scanning technique, 11 the ceramic material, 19 the CAD / CAM system used and 5 the cementation. Ten of these articles address multiple factors, therefore they are repeated in this description. Conclusions: All the factors evaluated seem to have some influence on the marginal adaptation of ceramic restorations made with CAD / CAM technology. However, the diversity of protocols adopted in the different studies limits their comparison. In future studies, it is necessary to have a greater standardization so that more reliable conclusions can be drawn from the point of view of scientific evidence.
