In the polymeric dental restorative composites, the resin matrix mainly contains 70w% 2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy)phenyl]propane (bis-GMA), as a base resin and 30w% triethylene glycol dimethacrylate (TEGDMA), as a diluent. However, the diluent exhibits adverse effects such as curing shrinkage and diminished mechanical properties of the dental composites. In this study, in order to reduce volumetric shrinkage of the current dental restorative composite resin, various novel organic monomers were developed by substituting alkoxy for hydroxyl groups in bis-GMA and spiro orthocarbonates were synthesized. Their mechanical properties and curing characteristics of dental composite fabricated from then were also explored. |
