Digitally Designed and Milled Verification Jigs Generated from Photogrammetry Data Acquisition: A Clinical Report

The objective of the present report is to illustrate a proof-of-concept protocol for CAD/CAM fabrication of milled verification jigs during full-arch implant rehabilitation using photogrammetry for data acquisition. The present report aims to bridge the gap between analog and digital workflows by introducing a CAD/CAM technique to intraorally verify digitally acquired information without the use of the technique-sensitive and labor-intensive conventional resin verification jig. One patient was treated with a digital prosthodontic protocol where a digitally designed CAD/CAM milled verification jig (generated from intraoral digital scans) was used to confirm implant 3D positioning prior to the fabrication of double full-arch monolithic definitive zirconia prostheses. The procedures are presented step-by-step after clinical and radiographic observation.
