Resumo
A obtenção de um modelo de trabalho fiel em implantodontia está relacionada principalmente às técnicas de moldagem e aos materiais utilizados. O objetivo desta revisão de literatura é apresentar os materiais e as técnicas de moldagem mais precisas utilizados em próteses implantossuportadas. Com base nos artigos revisados, verifica-se que a técnica de moldagem mais precisa é a de arrasto com transferentes quadrados unidos por meio de barras pré-fabricadas de resina auto ou fotopolimerizável associada a um material elastomérico (poliéter ou silicona por adição).

Abstract
The accuracy of dental implants is related to impression materials and dental impression techniques. This paper presents, according to scientific literature, the most precise impression materials and dental impression techniques used in implant prosthodontic rehabilitations. Based on the reviewed manuscripts, an elastomeric material (polyether and polyvinyl siloxane) associated to an open-tray pick-up impression technique (square transfer copings splinted) should be used in implant-supported dental prosthesis.
Keywords
