Resumo
Objetivo: Analisar a precisão técnica e a relação custo-benefício das tecnologias de impressão 3D Digital Light Processing (DLP) e Fused Deposition Modeling (FDM) na cirurgia ortognática. Métodos: Realizou-se uma revisão integrativa com busca nas bases PubMed, Scopus e Cochrane Library, selecionando ensaios clínicos e estudos experimentais comparativos. Os parâmetros avaliados incluíram precisão dimensional, redução do tempo operatório e viabilidade econômica de insumos. Resultados: O planejamento virtual associado à impressão 3D reduziu o tempo cirúrgico entre 40 e 83 minutos, apresentando erros lineares médios inferiores a 1,1 mm, o que satisfaz plenamente os requisitos clínicos. Enquanto a tecnologia DLP oferece ajuste clínico superior para splints oclusais devido à alta resolução, a técnica FDM com filamento PLA demonstrou ser a alternativa mais viável para produção interna hospitalar, reduzindo custos de insumos. Considerações finais: De modo geral, a tecnologia FDM demonstra potencial para democratizar o acesso à cirurgia de alta precisão devido à sua excepcional custo-efetividade. O estudo limita-se pela escassez de ensaios clínicos randomizados de longo prazo comparando diretamente ambas as tecnologias no desfecho de tecidos moles.
