The purposes of this study were to examine the shock absorption capability of addition-cured silicone denture relining materials and the bonding strength of addition-cured silicone denture relining materials and a commercial mouthguard material to determine its applicability to mouthguard adjustment. Two addition-cured silicone denture relining materials were selected as test materials. The impact test was applied by a free-falling steel ball. On the other hand, bonding strength was determined by a delamination test. After prepared surface treatments using acrylic resin on MG sheet surface, 2 types of addition-cured silicone denture relining materials were glued to MG surface. The peak intensity, the time to peak intensity from the onset of the transmitted force and bonding strength were statistically analyzed using ANOVA and Tukey's honest significant difference post hoc test (p<0.05). These results suggest that the silicone denture relining materials could be clinically applicable as a mouthguard adjustment material.
本研究的目的是检测加成型硅橡胶义齿重衬材料的减震能力以及加成型硅橡胶义齿重衬材料与一种商用护齿材料的粘结强度，以确定其在护齿调整中的适用性。选择两种加成型硅橡胶义齿重衬材料作为测试材料。通过自由落体钢球进行冲击试验。另一方面，通过分层试验测定粘结强度。在MG片材表面使用丙烯酸树脂进行表面处理后，将两种加成型硅橡胶义齿重衬材料粘贴到MG表面。使用方差分析和Tukey诚实显著差异事后检验（p<0.05）对峰值强度、从传递力开始到峰值强度的时间以及粘结强度进行统计分析。这些结果表明，硅橡胶义齿重衬材料在临床上可作为护齿调整材料应用。
