Abstract
|
|
|
2,2-Bis[4-(2-hydroxy-3-methacryloxy propyl)phenyl]propane(Bis-GMA) as a monomer of visible light cured dental composite resin was prepared and Bis-acetylated GMA was synthesized by acetylating the hydroxyl group of Bis-GMA for elimainating the hydrophilicity.
Synthesized monomer were identified by fourier transform infrared spectroscopy(FT-IR) and fourier transform nuclear magnetic resonance(FT-NMR).
Visible light-cured dental composite resrin were prepared from synthesized monomer and then compared water absorption with Silux^R, ready-made composite resin.
Resin was prepared from Bis-acetylated GMA had lowest water absorption about 0.27% for a day and no more absorbed water.
