제목 Esthetic Properties of Silica Nanofiller Dispersed Polymeric Dental Restorative Composites
초록 Silica nanofiller dispersed polymer composites was designed to be useful for dental restoratives. Three component hybrid-filler composed of barium silicate (avg. dia.: 1 ㎛) and fumed silica (avg. dia: 40 and 7 ㎚) was adopted as a filler system. To improve the interfacial behavior with the resin matrix of bisphenol A glycerolate methacrylate/triethyleneglycol dimethacrylate (60/40 wt%), filler's surface was hydrophobically treated with functional silane coupling agent. A visible light system of camphorquinone photo-initiator and 2-(dimethylamino)ethyl methacrylate photo-accelerator was utilized to activate the resin matrix in the polymer composites. Esthetic properties of composites prepared herein was investigated by measuring the Hunter L, a and b values.
