Alkoxide derived silica nanoparticles are most often synthesized by the sol-gel process, in which alkoxysilanes are allowed to undergo hydrolysis and condensation reactions. Resin composites have been successfully used in dentistry as esthetic filling restoratives for decades with their high mechanical strengths. However, lack of direct chemical adhesion to tooth and slow degradation make them not very useful without applying extra bonding agents. BisGMA based composite resin restoratives are known for their excellent esthetics, easy handling and improved mechanical strength, and wear resistance. In the present study, we use polymerizable silicananoparticles with BisGMA in order to achieve a higher mechanical strength as well as durabilities. The objective of this study is to synthesize and characterize nano dispersed organic/inorganic hybrids, to formulate them for use in nanocomposite resin restoratives, and to evaluate mechanical strengths of the formed composite resin. |
