Objective: The aim of this study was to assess the shear bond strength and the fracture resistance of zirconia based all-ceramic restorations with different veneering techniques. Method: For the shear bond strength testing, fifteen zirconia discs (7x 3 mm) were fabricated and divided into three groups (N=5). Discs of the first group (Group 1) were veneered by conventional layering technique. Discs of the second group (Group 2) were veneered by press-on technique. Discs of the third group (Group 3) were veneered by cementing the pressed veneering caps to the zirconia discs. The shear bond strength was tested by a universal testing machine. For the fracture resistance testing, fifteen zirconia frameworks intended for the first premolar crowns were fabricated and divided into three groups (Group 4, 5 and 6) as done in the disc specimens. The fracture resistance was tested by a universal testing machine. The data obtained from both tests were statistically analyzed by 1-way ANOVA and Tukey’s test. The failed specimens were evaluated by scanning electron microscope to determine the mode of failure. Results: For the shear bond strength, the mean and standard deviation values of shear bond strength were 7.9 ± 1.9 MPa, 23.3 ± 4.5 MPa and 20.2 ± 2.1 MPa for Group 1, Group 2 and Group 3. There was no statistically significant difference between Group 2 and Group 3; Group 1 showed the statistically significantly lowest mean shear bond strength. For the fracture resistance, the mean and standard deviation values of fracture resistance were 1268.2 ± 140.5 N, 1854.8 ± 323.7 N and 440.3 ± 105.3 N for Group 4, Group 5 and Group 6. Group 5 showed the statistically significantly highest mean fracture resistance. Group 6 showed the statistically significantly lowest mean fracture resistance. Conclusions: The press-on veneering technique was found to be the most reliable in terms of shear bond strength and fracture resistance.
