DENTAL FILLING MATERIAL, PROCESS FOR PRODUCING THE SAME, AND DENTAL COMPOSITE MATERIAL

摘要

A dental filling material combining the optical properties and mechanical properties which are required of dental materials; a process for producing the filling material; and a dental composite material containing the dental filling material. The dental filling material comprises fine particles of an amorphous inorganic oxide obtained by coating the surface of fine silica particles with a composite oxide comprising zirconium, silicon, and oxygen. The dental composite material comprises the dental filling material and a curable resin selected among an acrylic resin, methacrylic resin, epoxy resin, vinyl resin, urethane resin, etc.
