Optimal Design of Interface Geometry of Pocelain-Fused-to-Metal (PFM) Dental Crown – an Experimental Study

In conventional crown structure, the crowns are bonded to the bottom layer with a cement layer. The major clinical failure mode is the subsurface radial crack at the interface between the crown and cement. This failure is caused largely by the tensile stress concentration/singularity in the dental ceramic at that interface. A sharp change in […]
