Resin-composite blocks for dental CAD/CAM applications

Advances in digital impression technology and manufacturing processes have led to a dramatic paradigm shift in dentistry and to the widespread use of computer-aided design/computer-aided manufacturing (cad/cam) in the fabrication of indirect dental restorations. research and development in materials suitable for cad/cam applications are currently the most active field in dental materials. two classes of materials are used in the production of cad/cam restorations: glass-ceramics/ceramics and resin composites. while glass-ceramics/ceramics have overall superior mechanical and esthetic properties,resin-composite materials may offer significant advantages related to their machinability and intra-oral reparability. this review summarizes recent developments in resin-composite materials for cad/cam applications,focusing on both commercial and experimental materials. © international & american associations for dental research.
