Abstract:
PURPOSE: The purpose of this research was to evaluate the shear bond strength between zirconia core and veneer ceramic after surface treatment. MATERIAL AND METHODS: Zirconia cores (N = 40, n = 10, 10 mm x 10 mm x 3 mm) were fabricated according to the manufacturers??instructions and ultrasonically cleaned. The veneering ceramics (thickness 3 mm) were built and fired onto the zirconia core materials. Four groups of specimens with different surface treatment were prepared. Group I: without any pre-treatment, Group II: treated with sandblasting, Group III: treated with liner, Group IV: treated with sandblasting and liner. The shear bond strength was tested in a universal testing machine. Data were compared with an ANOVA and Scheffe post hoc test (P = .05). RESULTS: The shear bond strength of group VI was significantly higher than the other groups. CONCLUSION: Both mechanically and chemically treated simultaneously on zirconia core surface influenced the shear bond strength between the core and veneering ceramic in all-ceramic systems.
