Resumo
Os recentes avanços no design digital e na manufatura aditiva, ou impressão tridimensional, permitiram o desenvolvimento de diversos materiais dentários com múltiplas aplicações clínicas. Entre esses inúmeros usos, a confecção de restaurações provisórias realizadas por meio de impressão tridimensional ganhou grande popularidade nos últimos anos. Portanto, é desejável que os materiais utilizados na fabricação dessas restaurações exibam boas propriedades físicas e mecânicas para cumprir a função para a qual foram criados. O objetivo deste trabalho é estudar as propriedades físicas (cor-absorção de água) e mecânicas (resistência à compressão, resistência à flexão, resistência ao desgaste, dureza) dos materiais para restaurações provisórias obtidas por impressão tridimensional e compará-los com os materiais para provisórios obtidos pelo método de design e manufatura assistidos por computador, cad-cam e o método tradicional. Para isso, foi realizada uma busca em diversas bases de dados, como a Biblioteca Virtual em Saúde Odontológica, PubMed e Google Scholar, com um intervalo de datas de publicação de 2019 a 2024. Também foram incluídas as publicações que surgiram como referências dos artigos obtidos. Foi estabelecido um critério de elegibilidade para orientar a seleção. Dentre as limitações deste trabalho, foi possível concluir que os materiais para impressão tridimensional quando comparados com os materiais para provisórios cad-cam e método tradicional, apresentam limitações em suas propriedades físicas, mas apresentam resultados adequados em suas propriedades mecânicas. As restaurações provisórias feitas por meio da tecnologia de impressão tridimensional devem ser consideradas uma alternativa às feitas por cad-cam e método tradicional.
