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.

Traditional methods of designing and creating restorations are being increasingly replaced by digital processes. Software and hardware platforms for esthetic restoration design allow for local computer-aided design/computer-aided manufacturing (CAD/CAM) production. These systems are becoming ubiquitous and their strengths can be applied to the management of the esthetically discerning patient. This article takes a critical look at the effectiveness of digital workflows, including digital treatment planning using multiple datasets, linked digital workflows, digital restorative design, milled prototypes, and minimally veneered zirconia restorations. A complete digital workflow can be used in the treatment of the esthetically discriminating prosthodontic rehabilitation patient.
