• Note (General): Objective: Bis-GMA and UDMA that are widely used as main components of (meth) acrylic monomer compositions. However, the application of Bis-GMA which is a bisphenol A derivative was doubted in dentistry, after bisphenol A was revealed to have estrogenic activity. Although UDMA has considered as a substitute for Bis-GMA, the mechanical properties of cured resin composite containing UDMA are still insufficient. Therefore, in this study, I developed new alternative (meth) acrylic monomers to enhance the mechanical strength of cured products of composite resins. Methods: As a (meth) acrylic monomer substituted for Bis-GMA and UDMA, five urethane acrylic monomers were synthesized in this study. Elastic modulus, strength and breaking energy were measured through three points flexural test of cured resin from (meth) acrylic monomer mixture of the urethane acrylates and TEGDMA. Result: Three points flexural test of cured resin revealed that the newly synthesized urethane acrylates excels in a balance of mechanical properties, such as rigidity and toughness as compared with the cured UDMA -based resin. Conclusion: The new urethane diacrylates, TMXDI-HEA, TMXDI-HPA, XDI-HPA and NBDI-HEA, can be useful for restorative resin composites to substitute Bis-GMA and UDMA.; (主査) 教授 吉田 靖弘, 教授 井上 哲, 教授 佐野 英彦; 歯学研究科（口腔医学専攻）
