The purpose of the study was to compare the shear bond strengths of Zirconia core and veneer with Lithium Disilicate core and veneer. In the study 20 all ceramic bilayered specimens were fabricated and divided into two test groups containing 10 specimens each. Materials used were Zirconia samples and Lithium Disilicate samples. Nominally identical bar shaped core (Cercon and Lithium Disilicate) specimens of 5.0 mm length, 5.4 mm width and 13.0 mm height were produced following Schmitz-Schulmeyer method. After a thin layer was fired, veneering ceramic was built up to final dimensions (4.0 mm length, 5.4 mm width, 3.0 mm height) using a metal mold according to Schmitz-Schulmeyer method. Load was applied parallel to the long axis of the specimen through a wedge in an instron universal testing machine at the core-veneer interface at a crosshead speed of 5 mm/min until delamination of the veneering ceramic occurred. The results of the study demonstrated Zirconia having better bond strength compared to Lithium disilicate.
