Abstract
Aim: to evaluate the shear bond strength of zirconia bonded with two self etch adhesive resin cements Panavia F2.0 and Bistite ΠDC using two surface treatment techniques:sand blasting and silica coating using Cojet system. Materials & Methods: Twenty rectangular samples with dimensions (14.5×13×3.6mm) and twenty samples with dimensions (7.2×6×3.6mm) were cut from three zirconia ceramic blocks. Sandblasting was done using air blasting machine with 110 µm AL2O3 particles and Silica coating surface treatment was done using Cojet system with 30 µm SiO2 particles. Half of the small sandblasted zirconia samples were cemented to half the sand blasted large samples using PANAVIA F 2.0 adhesive resin cement and the rest were cemented using BISTITE ΠDC adhesive resin cement. Also, half of the small silica coated zirconia samples were cemented to half the silica coated large samples using both cements. Thermocycling were done for 5000 thermal cycles. The shear bond strength was tested using a computerized universal testing machine. Results: Zirconia specimens cemented with Panavia F2.0 showed higher shear bond strength than specimens cemented with Bistite ΠDC and the zirconia surfaces treated with silica coating and sand blasting surface treatments Conclusion: Panavia F2.0 resin cement and silica coating surface treatment could be the best cement and surface treatment for zirconia and sand blasting could be a promising alternative surface treatment.
