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.

Background. Type of materials used in fabrication of denture base has an effect on dimension during denture base material processing and other factors related to clinical use.Objective. The study aims were to assess the dimensional stability including thermal changes of three different denture base materials.Methods. Ninety patients were selected to construct complete dentures with different denture base materials. They were randomly divided into three groups: group 1, patients with cobalt chrome metallic base; group 2, patients with heat curing acrylic resin fabricated by injection moulding technique; and group 3, patients with denture bases fabricated by conventional heat curing acrylic resin. The dimensional changes were assessed using digital caliper.Results. After the twelfth month, injection moulding acrylic resin had significantly the highest dimensional change followed by the conventional heat curing acrylic resin. There were no significant differences in the dimensions between the three types of denture base materials at normal mouth temperature, while, after hot tea drinking at 45°C, the dimensional change was significantly the highest in cobalt chrome metallic denture base group.Conclusion. Cobalt chrome metallic denture base has stable dimension compared to denture bases fabricated of acrylic resin but it was more affected by altered mouth temperature. The study was registered in the International Standard Randomized Controlled Trials Number (ISRCTN) registry with study ID (ISRCTN94238244).
