THE ANALYSIS OF EFFECT OF DIFFERENT SURFACETREATMENT METHODS ON RESIN BONDING ON LONG TERM SUCCESS OF HIGH-STRENGTH CERAMICS

Introduction: Ceramics are still the most aesthetically pleasing materials available for restorative dentistry. However, due to the metal infrastructure of metal-supported ceramic systems, which were developed to increase the physical properties, esthetic and biological adaptations cannot be fully obtained. Objective of the study: The main objective of the study is to find the evidence on resin bonding related to long-term clinical outcomes of tooth- and implant-supported high-strength ceramic restorations. Methodology of the study: Four different surface processes were used as surface-treatment procedures. The first three procedures were applied to samples of IPS Empress and IPS Empress 2 ceramic discs. Sandblasting with Al2O3, blasting with soda and glass beads, and the Bateman etch retention system were applied to samples of In-Ceram ceramic discs. The discs were cemented to composite bars. Two types of cement were used; Rely X adhesive resin cement and Rely X modified glass ionomer cement and, all the samples were subjected to a shear test to evaluate their bond strengths. Results: With the IPS Empress and the IPS Empress 2 ceramic discs, the best bonding was obtained in the group etched with Al2O3 sandblasting and hydrofluoric acid after cementation using the Rely X adhesive resin cement. Conclusion: The in vitro findings from this study indicate that surface-treatment procedures applied to the IPS Empress and the IPS Empress 2 fullceramic systems are important when cement types are considered. In contrast, cement types and surface-treatment methods had no effect on changing the bond strength of the In-Ceram ceramic system. Key words: Ceramics, cement, treatment, bonding.
