Abstract(s)
Em reabilitações totais implanto suportadas, a falta de ajuste passivo entre implante e a prótese é uma das principais causas de complicações técnicas. As moldagens para implantes são etapas críticas na implantologia, podendo introduzir erros nas fases iniciais da reabilitação, se feitas de forma imprecisa.
Este estudo tem como objetivo realizar uma revisão sistemática atualizada, seguindo as diretrizes PRISMA, para avaliar a precisão de impressões convencionais e estereofotogramétricas em reabilitações totais implanto-suportadas. Usando a estrutura PICO, a pesquisa abrangeu quatro bases de dados (PubMed, ScienceDirect, Cochrane e Google Scholar) até agosto de 2023.
Foram analisados 13 estudos, incluindo avaliação de risco de viés. Nos estudos in vitro, todos apresentaram um baixo risco de viés, evidenciando robustez metodológica. Nos estudos in vivo, a qualidade metodológica variou, exigindo uma interpretação crítica mais exaustiva.
Os resultados demostraram elevada heterogeneidade, sublinhando a importância da padronização em estudos futuros para fornecer resultados mais confiáveis e comparáveis. O método de impressão convencional e a estereofotogrametria são relatadas como tendo precisão similar para registrar as posições dos implantes em situações de reabilitações totais. A posição, o número de implantes e angulações geralmente não interferem com a precisão da estereofotogrametria, mas a distância interimplantes demostrou ter alguma influência.
Conclui-se que a estereofotogrametria oferece uma alternativa tecnológica para as moldagens convencionais, destacando a importância da integração da digitalização dos tecidos moles para otimizar a eficiência. Contudo, são essenciais estudos clínicos adicionais com amostragem mais abrangente e protocolos robustos para validar estas observações.
In implant-supported total rehabilitations, the lack of passive adjustment between the implant and the prosthesis is one of the main causes of technical complications. Implant impressions are critical stages in implantology and can introduce errors in the initial phase of rehabilitation if done inaccurately. This study aims to conduct an up-to-date systematic review following the PRISMA guidelines to evaluate the accuracy of conventional and stereophotogrammetry impressions in implant-supported total rehabilitations. Using the PICO structure, the research covered four databases (PubMed, ScienceDirect, Cochrane, and Google Scholar) up to August 2023. Thirteen studies were analyzed, including bias risk assessment. All the in vitro studies showed a low risk of bias, demonstrating methodological robustness. In the in vivo studies, the methodological quality varied, requiring a more exhaustive critical interpretation. The results showed high heterogeneity, emphasizing the importance of standardization in future studies in order to provide more reliable and comparable results. The conventional method and stereophotogrammetry are reported to have similar accuracy for recording implant positions in total rehabilitation situations. Position, number of implants, and angulations generally do not interfere with the accuracy of stereophotogrammetry, but the distance between implants has been shown to have some influence. It is concluded that stereophotogrammetry offers a technological alternative to conventional impressions, highlighting the importance of integrating soft tissue digitalization to optimize efficiency. However, additional clinical studies with broader sampling and robust protocols are essential to validate these observations.
