Summary
Although an intraoral scanner IOS can offer the clinician a completely digital workflow, achieving trustworthy digital scans in edentulous jaws is challenging because of the lack of fixed anatomical landmarks. From this perspective, several methods have been proposed to improve the accuracy of digital scanning, however, related results remain inconclusive, and previously proposed devices have had limitations, such as bulkiness, excessive manufacturing requirements, and poor commercial applicability. Thus, this study aims to clinically compare the effect of conventional versus photogrammetry intraoral scanning methods on the passive fit of mandibular all-on four screw-retained frameworks.
