Effect of universal adhesives and surface treatments on shear bond strength to hybrid CAD/CAM Ceramics

Abstract

Aim: The purpose of this study is to investigate the effect of changes in hybrid ceramics to resin cement after the application of different surface treatments. Material and Method: In our work, 330 pieces of 3 different hybrid CAD-CAM ceramics were used. The ceramics were divided into 5 subgroups and their surfaces were treated differently. These were set as bonding with hydrofluoric acid, bonding with CoJet, Silane application with hydrofluoric acid, only bonding application, and control group. The shear bond strength was measured with a universal tester, INSTRON. Values from the measurements were analyzed by one-way ANOVA and the Tukey HSD test was used to determine significant differences (p = 0,05). Results: Bonding values between CAD/CAM hybrid ceramic blocks subjected to the same surface treatment were statistically significant in all HF applied samples. (p
