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 excellent chemical, sterilization resistance ,and mechanical properties, and synthesized etheretherketone based oligomer to investigate the possibility as dental restorative materials. This study aims to synthesize methacryloyl-etheretherketone (MA-EEK) using hydroxyl-terminated etheretherketone (HEEK) and methacryloyl chloride (MAC) and characterize them by FT-IR, 1H-NMR spectroscopies. The resin mixture was prepared by mixing MA-EEK and ethoxylated bis-GMA (EBPDMA) with the various ratio, and a silica derivative was added to improve the mechanical properties of the dental composite resin. To evaluate the mechanical properties, It was photopolymerized by DLP 3D printer and measured their mechanical properties, such as compressive and flexural strength.
