丙烯酸类树脂是丙烯酸类共聚物，其中偶尔加入增塑剂。由于使用的单体通常是义齿基托树脂的溶剂，因此预期衬垫与义齿的粘合性良好。另一方面，丙烯酸软树脂吸水、膨胀，最终变质;增塑剂分子被唾液浸出，内衬逐渐变硬。它们的口内功效是短暂的，并且它们对于扩展的临床使用并不令人满意。硅橡胶的弹性和初始耐吸水性优异。然而，随着时间的推移，它们也会吸收水分并开始恶化。衬垫通过粘合剂附着在义齿基托树脂上;但粘合效果较差，两种材料之间经常发生分离。此外，它们不能被适当地抛光或修剪。硅胶衬里材料的另一个缺点是可能会发生微生物降解。我们开发了含氟聚合物软衬垫（Kurepeet，Kurecha Co.，Tokyo，Japan），其化学稳定并显示出良好的耐溶剂性和耐磨性。此外，它们的吸水率很低。我们已经在临床上使用了内衬，并观察了其在体内的行为超过2年。的目的
The acrylic resins are acrylic copolymers to which plasticizers are added occasionally. Inasmuch as the monomers used are generally solvents for the denture base resins, reasonably good adhesion of the liner to the denture should be expected. On the other hand, acrylic soft resins absorb water, swell, and eventually deteriorate; the plasticizer molecules are leached out by the saliva, and the liners gradually harden. Their intraoral efficacy is short lived, and they are not satisfactory for extended clinical use. The silicone rubbers excel in their resiliency and their initial resistance to water absorption. However, in time they also will absorb water and begin to deteriorate. The liners are attached to denture base resins by an adhesive; but the bond is a poor one, and separations between the two materials often occur. Furthermore, they cannot be polished or trimmed properly. Another objection to the silicone lining materials is the possibility of microbial degradation. We developed fluoropolymer soft liners (Kurepeet, Kurecha Co., Tokyo, Japan) that are chemically stable and show good resistance to solvents and abrasion. In addition, their water absorption is low. We have used the liners clinically and observed their behavior in vivo more than 2 years. The objective of this
