Efforts to apply the adhesive properties of mussel proteins to the biomedical field have been performed for a long time, and positive results have also been reported. Therefore, it is expected that the adhesive ability of the catechol group will give excellent physical properties to restorative dental materials. We have devised an oligomer that incorporates catechol into the conventional dental material. Bisphenol A glycidylmethacrylate (Bis-GMA) has been used for restorative materials because of many advantages such as higher mechanical property and low polymerization shrinkage. In this study, protocatechuate-BisGMA (PCA-BG) was synthesized by reacting Bis-GMA and protocatechuic acid (PCA) containing catechol group. In order to enhance their peoperties, hybrid dental resin was synthesized from PCA-BG and silica nanoparticles and used to evaluate its compressive and diametral tensile strengths after it was fabricated to use digital lighting processing (DLP) 3D printer.
