The silicone-based resilient denture liners have common shortcoming, peeling from denture base. Considering Japan is aging society, elder complete denture wearers are likely to use dentures with resilient denture liner for long-term due to their highly absorbed alveolar ridge. Therefore, the peeling of resilient denture liner from the denture base is huge issue. The aim of this study was to develop an adhesive monomer for resilient liner to support denture wearers with living well.We synthesized two types of adhesive monomer for resilient liner, 3-methacryloxy-1-propen and 11-hydroxy-undecene. After the adhesive monomers were applied, the bonding strength between denture base and resilient dentuure liner were confirmed by tensile testing. However, the bonding strength between denture base and resilient dentuure liner obtained from newly developed adhesive was not greater than that from existing adhesives.

硅橡胶弹性义齿衬垫有一个共同的缺点，即从义齿基托上脱落。考虑到日本是老龄化社会，老年人的牙槽嵴高度吸收，他们可能会长期使用带有弹性义齿衬垫的义齿。因此，弹性义齿衬垫从义齿基托上脱落是一个巨大的问题。本研究的目的是开发一种用于弹性衬垫的粘合剂单体，以支持义齿佩戴者的良好生活，我们合成了两种用于弹性衬垫的粘合剂单体，3-甲基丙烯酰氧基-1-丙烯和11-羟基十一烯。应用粘接剂单体后，通过拉伸试验确定义齿基托与义齿弹性衬垫之间的粘接强度。然而，使用新开发的粘合剂获得的义齿基托与弹性义齿衬垫之间的粘合强度并不大于现有粘合剂的粘合强度。
