The purpose of this study was to evaluate the effect of post-processing heat treatment on the fracture strength of a heat-pressed lithium disilicate dental ceramic (OPC 3G). Bar-shaped wax patterns (2 x 4 x 22 mm; n = 60) were invested and heat pressed in an automated pressing machine according to m
