Purpose: The plan for this study was to anatomise the effect of alternative surface treatments to enhance bonding to zirconia. Materials and Methods: forty discs of zirconia (Prettau,zircon zhan, Italy) were prepared using Isomet 4000 precision Saw then discs were divided into 5 groups. Group 1, control; Group2, zirconia discs were treated with50-mm Al2O3 particles; Group 3, zirconia discs were received hand grinding; Group 4, zirconia discs were treated by a CO2 laser and Group 5, zirconia discs were treated using ERYAG laser. Composite resin discs were constructed and cemented to zirconia samples with panavia cement. For the bond strength …
