Abstract

Purpose: The purpose of this study was to investigate the wear resistance of prosthodontic luting materials with a titanium framework by means of an in vitro three-bodied wear-testing device. Materials and Methods: The surfaces of flat cast titanium disks were blasted with 50 mum alumina. Placing a50 mum masking tape on the plane surface, the disks were bonded with five luting materials. The axial surfaces of the bonded disks were ground flat with 600 grit silicon-carbide paper, and then cyclically loaded (75.6 N, 1.2Hz) by a chewing simulator for 400,000 cycles. The distance between titanium and cement surfaces was measured in micrometers by means of a profilometer to determine Delta wear, and the surface texture was evaluated with a scanning electron microscope. Results: The Delta wear measurement showed thatthe resistance of Super-Bond Opaque adhesive was significantly higher thanPanavia Fluoro adhesive and Fuji I cement after 400,000 wear cycles. No significant differences were detected among Super-Bond Opaque adhesive, Super-Bond adhesive, and All-Bond adhesive. Visually, continuity with the titanium framework was observed when the titanium disks were luted with resin systems.
