Preparation of polymeric dental restorative materials (PDRM) showing a lower polymerization shrinkage was carried out using the hybrid-filler and 2,2'-bis-[4-(3-methacryloxy-2-hydroxypropoxy) phenyl]propane resin matrix that is diluted with a high molecular weight dimethacrylate monomer. A visible light system was utilized to activate the resin matrix for the polymerization. In order to enhance the miscibility of the inorganic hybrid-filler with organic resin matrix and to conduct the homogeneity of the filler in the PDRM, its surface was hydrophobically treated with gamma-methacryloxypropyltrirnethoxysilane. The degree of conversion (DC), depth of cure, and polymerization shrinkage of the PDRM were investigated. The results revealed that PDRM prepared herein showed markedly lower polymerization shrinkage values. Besides, regardless of the filler loading, both DC and depth of cure values decreased with an increase in the amount of less flexible diluent in the resin matrix.
