Abstract
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 test, a universal testing machine was used. Results: the highest shear bond strength was recorded for (Hand grinding) group (2) while the lowest mean value was recorded for control group (1). Conclusions: Treatment of Zirconia Surfaces with hand grinding or sandblasting increased shear bond strength. Treatment of Zirconia with CO2 and ERYAG lasers increased shear bond strength of zirconia, with the CO2 laser being higher than ERYAG laser.
