Comparative Evaluation of Shear Bond Strength of Veneering Porcelain to Zirconia Core using Different Surface Treatments: An in Vitro Study
Dr. Poonam Pathania, Dr. Swati Sharma, Dr. Samarjit Singh Teja
Surface treatments are needed to improve bond strength between zirconia and veneering porcelain. The purpose of this study was to test the shear bond strength of veneering ceramic to zirconia core after different surface treatments. The aims and objectives of the study was to evaluate the effect of surface treatments on shear bond strength between zirconia and veneering ceramic and to compare the effect of surface treatments on shear bond strength. A total of 30 square shaped zirconia samples were prepared and then divided into three groups on the basis of surface treatment. The three different surface treatments were: airborne abrasion (Group A), application of liner (Group B) and application of slurry of dentine (Group C). A cylinder of veneering ceramic was then fabricated and fired on the zirconia specimens. Each specimen was then tested for shear bond strength with the help of universal testing machine. The mean and SD shear bond strengths of the groups ranged from for (Group A) 16.01±2.57 MPa, (Group B) 15.14±1.76 MPa to (group C) 21.33± 4.16 MPa. Group C had the maximum shear bond strength followed by Group A with Group B showing minimum bond strength.
