Evaluation of Effect of Zirconia Surface Treatment with CO and Nd:YAG Lasers on Shear Bond Strength between Zirconia Frameworks and Porcelain Veneers.

Aim: The purpose of this study was to evaluate the effect of zirconia surface treatment with CO and Nd:YAG laser on shear bond strength (SBS) between the zirconia framework and porcelain veneering.

Materials And Methods: In this study, zirconia blocks were converted to 50 cubes and were divided randomly into 5 groups. After sintering (S), porcelain was applied in the control group.
