Objective:The purpose of this study was to evaluate the shear bond strengths of heat-pressed and layered ceramics with regard to their corresponding metal alloy. Methods:12 Co-Cr alloy and 12 Au-Pt alloy specimens were cast and divided into 2 groups (n = 6). Metal specimens were veneered with ceramics to produce shear test specimens:experimental groups:PoM (A1:PoM/Co-Cr,A2:PoM/Au-Pt) and two control groups:VMK95 (B1:VMK95/Co-Cr,B2:VMK95/Au-Pt). Shear bond strength testing was conducted in a universal testing machine,and the failure strengths were recorded. SEM was utilized to analyze the metal-porcelain interface. Results:Bond strength of PoM groups was significantly higher than that of VMK95 groups and all the groups displayed mixed failure mode. SEM revealed morphologically that in the PoM groups,the veneer layer contacted more closely and tightly to the alloy,and fewer pores were shown in the interface. Conclusion:Heat- pressed Technique shows greater bond strength between metal and the veneering porcelain.
