Dental resins need strong durability, low shrinkage, biocompatibility and easy polymerization. In order to get better chemical and mechanical properties, we focused on poly(ether ether ketone) (PEEK) structure, which has good chemical, sterilization resistance and excellent mechanical properties, and synthesized etheretherketone based oligomer to investigate the possibility as a dental restorative materials. The aim of this study is to synthesize methacryloyl-etheretherketone (MA-EEK) using hydroxyl-terminated etheretherketone (HEEK) and methacryloyl chloride (MAC) and characterize them by FT-IR, 1H-NMR spectroscopies. To evaluate physical properties, the mixture of MA-EEK and ethoxylated bis-GMA (EBPDMA) with various ratios were photopolymerized by DLP 3D printer and measured their mechanical properties, such as compressive and flexural strength. |
