A Preliminary Evaluation into the Performance of Posterior Resin Bonded Cast Metal Restorations (Adhesive Onlays)

Abstract - Posterior resin bonded cast metal restorations (adhesive onlays) were used in a variety of clinical scenarios including: management of tooth wear and cracked tooth, as retainers for fixed bridge work, for correction of the occlusal plane and in providing cuspal coverage following endodontic treatment. The mean length in service for the examined onlays was 42 months, with a range of 9-75 months. Two restorations in two patients failed resulting in an overall success of 94%. Patient satisfaction was high at 95%. Such restorations seem to be a viable option for managing a number of clinical scenarios.

KEY WORDS: Resin bonded cast metal restorations, adhesive onlays, cracked tooth, bridge retainers, tooth wear
