Zirconia Crown Retention on Conventional Versus Screw Channel Correcting Abutments

Abstract

Computer-aided design and Computer-aided manufacturing (CAD/CAM)systems are used to design and fabricate ceramic restorations. A common workflow to restore dental implants is cementing a monolithic zirconia crown to a prefabricated titanium abutment. Depending on the position of the implant, a conventional or screw channel correcting abutment can be utilized. Screw channel correcting abutments exhibit a design feature that introduces a window along the axial surface, reducing the abutments surface area, and possibly compromising crown retention.
