Abstract

In this paper, moire interferometry and finite element analysis (FEA) have been applied to study interface fracture behaviors of Porcelain-fused-to-metal (PFM) restoration. The fracture criterion of an interface crack between the porcelain and metal is based on the maximum stress. The influence of the thickness ratio, load value and load form on the predicted kinking angles has been proposed and discussed. It is shown that the predicted kinking angle does not varied with load value. The magnitude of crack-kinking angle is more sensitive to load from than to thickness ratio. Measured data accord well with numerical value. These results provide data for the optimized design of clinical PFM restoration and for understanding fracture mechanism of the restoration.
