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¡¿10 mm¡¿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¡Çpost 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 allceramic systems.
