Introdução: A tecnologia CAD/CAM possui múltiplas aplicações protéticas, incluindo a prótese total. Objetivos: realizar uma revisão de literatura sobre a aplicabilidade dos sistemas CAD/CAM na fabricação de próteses totais, a fim de elucidar as propriedades das próteses confeccionadas através dessa tecnologia e as características desse sistema. Metodologia: A busca por artigos científicos que contemplassem o tema foi realizada através das bases de dados PUBMED e SCIELO, sem restrição de período. Foi feita a análise dos títulos e resumos e em seguida o acesso ao texto completo. Resultados: Dentre as características do sistema CAD/CAM, os estudos citaram menor necessidade de consultas e tempo clínico. É preciso conhecimento da tecnologia pelo cirurgião-dentista e o maior custo laboratorial é uma das desvantagens de sua utilização. Quanto às propriedades, observa-se a redução da rugosidade e porosidade, assim como da adesão de Candida albicans à base da prótese e teor de monômero residual. Maior dureza de superfície é verificada em comparação com as próteses totais convencionais. Conclusão: Menor número de consultas e tempo clínico são características do uso do sistema CAD/CAM em prótese total. Maior dureza da prótese e redução da rugosidade, porosidade, adesão de C. albicanse do teor de monômero residual são propriedades que as próteses totais apresentam quando confeccionadas por essa tecnologia.Descritores: Odontologia; Prótese Total; Projeto Auxiliado por Computador.ReferênciasAlbero A, Pacual A, Camps I, Grau-Benitez M.

A commentary is presented on the review paper by Dr. Braden on the state of the art of the "science of resins" in dentistry. The subject area is defined as principally including those materials involved with the denture-base applications. Recent studies involving investigations of structure and properties are noted. Most reports of properties have concentrated on physical, chemical, and mechanical properties. The limited amount of information on biological properties is noted. The absence of clinical investigations of materials performance is emphasized. Future research strategies should concentrate on areas which involve clinical research information, other product properties, and the adaptation of new technology to these applications. CAD/CAM is suggested as an example of this new technology. Finally, investigators in the area are admonished to take advantage of information management systems, to collaborate more with each other, to collaborate more with industry, and to focus more on a few promising systems in order to produce significantly better denture-base materials for clinical practice.
