The purposes of this study were to measure strengths of layered porcelain fused to titanium beams, determine failure modes, and investigate the porcelain-titanium interface. A three-point flexural test and formulas derived especially for this purpose were used. The strength of layered porcelain-ceramic beams was limited by the cohesive tensile or compressive strengths of the porcelain, not by the porcelain-titanium interfacial bond, namely, the porcelain failure occurred at lower loads than did failure of the porcelain-titanium interface. The porcelain-titanium bond strength was at least 26 MPa. Scanning electron microscopy and energy-dispersive x-ray spectroscopy demonstrated that the bond was limited by delamination of a thin titanium-titanium oxide interface. Theoretic curves that describe effects of relative layer and total thickness on the force-bearing capacity of model beams were plotted. These curves indicated that porcelain-titanium prostheses should be made as thick as is practical, but the relative thickness of the porcelain and titanium layers would be less important.
