In vivo and in vitro comparison of internal and marginal fit of digital and conventional impressions for full-coverage fixed restorations: A systematic review and meta-analysis

ConclusionsDifferences in marginal adaptation between the digital and conventional groups are not significant for in-vivo studies, but for in-vitro studies, digital impression resulted in better marginal adaptation. Based on the GRADE approach for marginal adaptation, clinical studies were classified as high confidence and in-vitro studies was graded moderate due to the inconsistency. Furthermore, high-quality studies are needed to confirm our results (PROSPERO; CRD42017077925).
