Introduction: In the prosthetic rehabilitation of the maxillary anterior region, zirconia restorations are frequently used. Aim: To evaluate the shear bond strength between zirconia post and composite resin core material with different surface treatment. Material and Methods: Total 80 samples of sintered zirconia blocks (5mm X 5mm X 2mm) were fabricated for this study. These zirconia blocks were fixed on acrylic block and four different groups were made on basis of surface treatment. Group 1 (G1) no surface treatment, Group II (G2): Laser etching with Er: YAG laser, Group III (G3): Internal coating (INT) with silica based porcelain, Group IV (G4): Aluminium nitride nano particles. After surface treatment, zirconia primer was applied over surface treated zirconia specimen. Composite resin blocks were fabricated with help of glass mold measuring 5mm X 5mm X 2mm and luted with same compo.. Read More»
