Development of adhesive monomer for resilient liner to support longevity with wellness of elders

硅胶弹性义齿衬垫有共同的缺点，从义齿基托上剥落。考虑到日本正在老龄化社会，老年人全口义齿佩戴者可能会长期使用具有弹性义齿衬里的义齿，因为他们的牙槽骨高度吸收。因此，弹性义齿衬里从义齿基托上剥离是一个巨大的问题。本研究的目的是开发一种弹性衬垫粘接单体，以支持生活良好的义齿佩戴者。我们合成了两种弹性衬垫粘接单体3-甲基丙烯氧基-1-丙烯和11-羟基十一烯。使用粘结剂单体后，通过拉伸试验确定义齿基托与弹性义齿衬里之间的粘结强度。然而，新开发的粘结剂获得的义齿基托与弹性义齿衬里之间的粘结强度并不高于现有粘结剂。

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.
