A study of shear bond strength between porcelain and alloy pretreated with sandblasting, sputter etching, and sputter etching after sandblasting was established by Instron universal testing machine. 1. Sputter etched group after sandblasted(group IV) and sandblasted group(group II) were stronger than control group(group I) (P<0.05). 2. Sputter etched group(group III) and control group(group I) were not different(P>0.05).
