Factors Affecting The Core Veneer Bond Strength Of Metal Ceramic Restorations: A Review

Statement of Problem: One of the most common causes of failure of any metal ceramic restoration is the delamination of the veneering ceramic. This may be attributed to failure at the junction of metal and ceramic. To evaluate factors affecting the core veneer bond strength of metal ceramic restorations through a review of previously published articles. Materials and methods: A thorough search was made in Pubmed and Google Search and articles collected were reviewed with respect to various factors affecting the core veneer bond strength of metal ceramic restorations. Results: Most of the studies done were in vitro. Of all the factors evaluated, surface treatments were found to have a significant effect on the bond strength. Conclusion: Metal ceramic compatibility, types of metal alloys, types of ceramic, various pretreatment methods, etc affects the bond strength of metal ceramic restoration. The effect of each of these variables should be properly understood and applied in the given clinical situation for predictable results.
