Use of intraoral scan for implant-supported dental prosthesis to design and fabricate a CAD-CAM verification device: A dental technique

Complete Digital Workflow for Prosthesis Prototype Fabrication with the Double Digital Scanning (DDS) Technique: A Prospective Study on 16 Edentulous Maxillae

“…Even though the digitally fabricated prototypes presented with accurate fit, the verification jig and the fabrication of a master cast remain the standard process of the full-arch implant workflow reconstructions. [15][16][17] This can be easily done with different approaches such as intraoral splinting of copings or abutments and then connecting analogs prior to pouring a jig cast or similarly back-pouring the conversion prosthesis after connecting analogs. [15][16][17] A digital alternative to verification is using the STL data from a digital full-arch scan to fabricate a digitally designed milled or printed verification jig through a complete digital workflow.…”

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

“…The present case report shows how the complete digital workflow can be used to efficiently streamline and expedite implant treatment for the edentulous jaw. The importance of the fabrication of a verification jig and a stone index cast generated from the verification jig has been shown by several studies 15–18 . With the presented protocol for verification jig CAD/CAM fabrication, chairside time is reduced and the cost of implant treatment may be decreased, while treatment may be simplified 7,17 …”

“…This discrepancy in the perceived validity of each workflow has led practitioners in both the digital and analog worlds to verify implant working casts prior to the fabrication of definitive prostheses. Traditionally, the analog workflow required the fabrication of resin verification jigs to confirm that analog working casts are an accurate representation of the intraoral three‐dimensional (3D) implant positioning 15–18 . During the digital workflow, the verification step currently necessitates that the clinician revert to an analog workflow in order to fabricate an acrylic resin verification jig and a stone index cast generated from the verification jig 15–18 .…”

During the digital workflow, the verification step currently necessitates that the clinician revert to an analog workflow in order to fabricate an acrylic resin verification jig and a stone index cast generated from the verification jig 15–18 . Therefore, in addition to adding a cumbersome clinical and laboratory step, this interchange between the analog and digital workflows is counter‐productive to the clinicians operating entirely within the digital workflow.…”
