Propriedades mecânicas dos sistemas cerâmicos CAD/CAM: revisão de literatura.

Abstract

The computer aided design / computer aided manufacturing (CAD/CAM) system, is one of the most technological and modern resources in oral rehab today. It is an alternative that optimized the resistance and the adaptation of dental ceramics. In this way, its indications of use have been widened, making it more and more known and widespread. The aim of this study is to present a review of the literature about the mechanical properties of CAD/CAM systems. A search for scientific articles published between the years 2010 and 2018 was done, through the databases SCIELO, BIREME and PUBMED, using the descriptors: "Ceramics", "Computer Aided Design" and "Fixed Partial Prosthesis", besides the analysis content the textbooks in the area. Currently all ceramic systems appear to have adequate strength for simple rehabilitations, but ceramic restorations produced by CAD / CAM systems present greater reliability than other manufacturing methods; presenting greater possibilities of indications due to their higher values of mechanical resistance.These systems, besides their versatility, also present an excellent aesthetic result, guaranteeing restoration, appropriate optical properties such as translucency and fluorescence, similar to the dental structure. This technology although presenting the cost as a limiting factor, is in full development and it is already a frequently used resource and with success rates that qualify it as the state of art in oral rehabilitation.
