Abstract:
The authors have questioned the accuracy of intraoral scanning when restoring the full arch implant patient. Yet clinicians use intraoral scanning (IOS) for this purpose due to the many efficiencies that the IOS workflow offers. This article describes a workflow that is used to enhance the accuracy of the intraoral scan without the need to use photogrammetry. It uses a design file for the provisional prototype restoration to create both a one piece prototype prosthesis and a segmented verification prosthesis. This verified workflow has the efficiency and comfort of the IOS workflow and the accuracy of the traditional workflow.
