Abstract :
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.
