## Abstract Previous work has shown that heat pressing of mica‐based glass‐ceramics can lead to crystal alignment along the direction of pressing. The purpose of this study was to evaluate the effect of heat pressing on the fracture toughness of mica‐based glass‐ceramics. Glass rods (12 × 60 mm) we
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
