ABSTRACT
Statement of problem: Metal ceramic restorations continue to be widely used in dental practice, as they combine esthetics with superior mechanical properties. Unfortunately they are prone to fracture due to their brittle nature. Purpose: Direct intraoral repair of fractured porcelain traditionally relied on mechanical roughening of the fractured surface, followed by application of a silane coupling agent to enhance the resin-to-porcelain bond. The primary advantages of using composites for repair are less chair time, lower cost, and ease of use. Indirect repair techniques that use porcelain require clinical and laboratory procedures but are advantageous because of the esthetic ability of porcelain to match the remaining ceramic units. This review article describes the repair of fractured porcelain fused to metal restorations. Conclusion: Shear bond strength studies using direct as well as indirect repair methods show promising results. However some improvements in the bonding techniques are still needed.
