In this study, bisphenol A glycidyl methacrylate (BisGMA) based trifunctional polymerizable oligomer was synthesized and characterized, used to formulate with TEGDMA as a diluent and colloidal silica as a nanofiller to be used as compomers. The homogeneous dispersions of colloidal silica were examined using TEM. A series of experimental composites with various ratios of oligomers up to 3% was fabricated, and evaluated their mechanical strengths such as compressive strength(CS), diametral tensile strength(DTS). It was resulted that dental composites with trifunctional oligomer showed higher CS and DTS as well as lower shrinkage, especially that with 0.5% oligomer content. |
