Abstract
Purpose: To examine the shear bond strengths of zirconia and veneering ceramic according to their surface processing.
Methods: The test samples were divided into three groups: one without zirconia surface processing, one sandblasted, and one sandblasted then 3% etched. Then veneering ceramic was fired on all test samples, and their shear bond strengths were measured.
Results: The test samples of the control group (Z1) showed the lowest shear bond strengths of MPa. The shear bond strengths of Z2 and Z3 ( and MPa, respectively) were relatively higher than those of the control group. The fracture surface of the control group showed adhesive fractures while the test groups had relatively large numbers of cohesive fractures.
Conclusion: The shear bond strength was high in the test groups with surface processing while the fracture surfaces showed compound fractures of adhesive and cohesive fractures.
