The purpose of the present study was to compare the properties required for the clinical application of soft lining materials containing a fluorinated monomer versus that of conventional materials in an effort to develop a new soft lining material with long-term stable viscoelastic properties. Four soft lining materials were examined. Two experimental materials containing dodecafluoroheptyl methacrylate (SR12F) or tridecafluorooctyl methacrylate (SR13F) were prepared. Two commercial soft lining materials, one acrylic-based and one silicone rubber-based, were selected as reference materials. Shore A hardness, viscoelastic properties, water sorption, solubility, and staining resistance were evaluated. The Shore A hardness and the displacements were analyzed with two-way analysis of variance (ANOVA) and Tukey's HSD test. The water sorption, the solubility and the color change were analyzed with one-way ANOVA and Tukey's HSD test. The significance level was set at 0.05. SR12F and SR13F showed greater viscous flow, low water sorption, low solubility, and good staining resistance compared to the commercial products. The results indicate that the soft lining materials containing fluorinated monomers might have a potentially long-term stable viscoelastic behavior.
本研究的目的是比较含有氟代单体的软衬材料与传统材料的临床应用所需性能，以期开发出具有长期稳定黏弹性能的新型软衬材料。本文研究了 4 种软衬材料。两种实验材料分别含有十二氟庚基甲基丙烯酸酯（SR12F）和十三氟辛基甲基丙烯酸酯（SR13F）。两种商业软衬材料，一种为丙烯酸基，另一种为硅橡胶基，被选作参考材料。评估了邵氏 A 硬度、黏弹性能、吸水性、溶解度和耐染色性。用双因素方差分析（ANOVA）和 Tukey 的 HSD 检验分析邵氏 A 硬度和位移。用单因素方差分析和 Tukey 的 HSD 检验分析吸水率、溶解度和颜色变化。显著性水平设为 0.05。与商业产品相比，SR12F 和 SR13F 表现出更大的粘性流动、低吸水性、低溶解度和良好的耐染色性。结果表明，含有氟代单体的软衬材料可能具有潜在的长期稳定黏弹行为。
