Commercial organic matrixes of dental composites generally include diluents such as triethylene glycol dimethacrylate (TEGDMA) to reduce viscosity. However, the diluenet exhibits adverse effects such as curing shrinkage and diminished mechanical properties of the dental composite. To overcome these adverse effects, organic monomers that can be used as an orgnic matrix may be developed. In this study, various novel organic monomers were developed by substituting alkoxy for hydroxyl grops in 2,2 bis [4-(2hydroxy3-methacryloyloxy propoxy) phenyl] propane] (Bis-GMA). Viscosities of the alkoxy-substituted monomers were decreased by increasing substituent size. These monomers could be used as organic matrixes of dental composites without an additional diluenet. Among these monomers, 2,2 bis [4-(2butoxy3-methacryloyloxy propoxy) phenyl] propane] (Bis-B-GMA) exhibited the lowest curing shrinkage. |
