Abstract
The purpose of this study was to evaluate of shear bond strength in two kinds of porcelain fused to non-precious alloy.
The Instron testing machine, operating at a cross-head speed of 0.5㎜/min, was used to break the bond between the porcelain and the Vera-bond metal.
The shear bond strength was computed from the load required to break the bond divided by the porcelain-surface bond area.
The result were as follows :
1. Shear bond strength was obtained through Uni-bond porcelain was fused to Vera-bond metal, showed 12941 psi in push test and 9.099 psi in pull test, respectively.
2. Shear bond strength was obtained through Bio-bond porcelain was fused to Vera-bond metal, showed 13.057 psi in push test and 9469 psi in pull test, respectively.
