Polymer nanocomposites (PNC) was designed to be useful for dental restoration. As a filler system, three component hybrid-filler of barium silicate and two kinds of silica nanofiller was adopted. To improve the interfacial behavior with the resin matrix composed of bisphenol A glycerolate methacrylate/triethyleneglycol dimethacrylate, filler's surface was hydrophobically treated with a silane coupling agent. Dental properties of PNC was investigated by measuring the abrasion resistance, polymerization behavior, and esthetic properties. It was discovered that PNC showed excellent properties with an increase of nanofiller content. However, the polymerization shrinkage was consistently maintained under 3 vol%. Additionally, a slight color difference between PNC specimens was observed with an increase of nanofiller content. |
