Resilient denture liner materials can be useful for tissue-supported implant-retained overdentures. They allow physiologic movement of the denture toward the tissues. This article presents a technique that offers several advantages over other methods of fabricating the overdenture with a resilient liner, and of transferring the superstructure: the acrylic resin base and the heat-cured resilient liner material are cured simultaneously; superstructure blockout is performed in the laboratory instead of in the mouth, where blockout is difficult; and direct transfer of the superstructure bar is more accurate and eliminates possible fracture of the duplicated superstructure if formed in die stone.
弹性义齿衬垫材料可用于组织支持式种植体固位覆盖义齿。它们允许义齿向组织进行生理性移动。本文介绍了一种技术，该技术相对于其他用弹性衬垫制作覆盖义齿以及转移上部结构的方法具有多个优点：丙烯酸树脂基托和热固化弹性衬垫材料同时固化；上部结构的封闭在实验室而非口腔内进行，因为在口腔内封闭操作困难；并且上部结构杆的直接转移更精确，还消除了如果在石膏模型中制作复制的上部结构时可能出现的断裂情况。
