The aim of this study is to evaluate the bond strength of an experimental Zirconia to a veneering porcelain and to Zirconia comercially available for use in CAD / CAM systems. The groups will be: Experimental Zirconia (EZ), Schuetz Zirconia (SZ) and Zirkonzahn Zirconia (ZZ). The blocks of pre-sintered zirconia (n = 20) will be cut into disks and taken to the oven for final sintering. Then…
