Fatigue behavior and crack initiation of CAD/CAM resin composite molar crowns

Computer-aided design/computer-aided manufacturing (CAD/CAM) resin composite blocks (RCBs) containing a high density of nano-filler particles are available for use in posterior restorations [1]. Because of the preliminary polymerized resin matrix, the nano-filler particles are homogeneously dispersed in the resin matrix, providing stable and excellent mechanical properties such as flexural strength and fracture toughness when compared with those of conventional resin composites used in fillings [2,3].
