  • Title: Use of a CAD-CAM poly(methyl methacrylate) interim prosthesis for direct intraoral splinting.
    Author: Proussaefs P.
    Journal: J Prosthet Dent; 2017 Dec; 118(6):706-711. PubMed ID: 28526429.
    Abstract:
    This article describes a technique where an interim computer-aided design and computer-aided manufacturing (CAD-CAM) prosthesis is milled from a poly(methyl methacrylate) blank to confirm esthetics, occlusion, function, phonetics, and accessibility for oral hygiene. The interim prosthesis is then sectioned and reconnected intraorally with autopolymerizing acrylic resin. This interim prosthesis is used to fabricate the definitive stone cast. The interim prosthesis is then scanned with a laboratory scanner. By applying this technique, the implant positioning can be related to the occlusal plane, the contours of the teeth, and the flange. The clinician can more effectively design the definitive prosthesis because the location of the implants and the exact contours of the teeth are all captured in a single digital file.
