Bisphenol A glycidylmethacrylate (BisGMA) has been used for restorative materials and it has many advantages such as higher mechanical property, low volatility, low polymerization shrinkage. The catechol group in protocatechuic acid has good bioadhesive properties. In this study, protocatechuate-BisGMA was synthesized by reacting BisGMA with protocatechuic acid and characterized by FT-IR, 1H NMR spectroscopies. The 3D printable restorative resin was prepared by photopolymerizing PCA-BG and ethoxylated BisGMA(EBPDMA), and used to evaluate compressive and flexural strengths by UTM. This was compared with resins that were photopolymerized with EBPDMA and Bis-GMA. |
