Abstract:
A dental resin composite comprising a thermally cured composition of polymeric resin monomers and inorganic fillers that comprise at least 80 wt % total filler loading is provided. Mill blocks made from the dental resin composite and produced via free radical polymerization under high-temperature (approximately 160° C. to 220° C.) and high-pressure process (approximately 300 MPa to 560 MPa) exhibited enhanced mechanical strength and good esthetics suitable for use in CAD/CAM indirect restorations such as, inlays, onlays, crowns and bridges.
