Influence of virtual facebow designs on the accuracy of face scan‐based virtual facebow records

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the accuracy of static maxillary‐facial spatial registration obtained using different virtual facebow (VF) fork designs and two facial scanning systems. Accuracy was assessed in terms of trueness and precision of linear deviations at three maxillary point references and angular deviation of the occlusal plane.

Relative accuracy of intraoral photogrammetry and intraoral scanning with conventional scan‐body for full‐arch implants

Journal of Prosthodontics, EarlyView.
Abstract Purpose To compare the relative accuracy of intraoral photogrammetry (IPG) and intraoral scan (IOS) with conventional scan bodies (IOS‐CB) for complete‐arch implant impressions, using the conventional splinted open‐tray impression digitized with a laboratory scanner (COT‐LS) as the reference standard.
