本研究的目的是研究义齿软衬在37°C水中长时间浸泡对粘弹性的影响。选择6种硅树脂基和2种丙烯酸树脂基义齿软衬。将圆柱形样品在37°C的蒸馏水中储存6个月。使用蠕变仪测定粘弹性性质，即瞬时和延迟弹性位移、粘性流动和残余位移，并采用双因素方差分析和Tukey比较法（α=0.05）进行分析。粘弹性性能和它们的时间依赖性的变化是不同的材料检查。所观察到的粘弹性性能的三个从六个硅基衬里没有显着改变后，6个月的浸泡，但那些两个丙烯酸树脂基衬里显着改变，随着浸泡时间的增加。然而，两个丙烯酸树脂基内衬在6个月浸泡期间的初始瞬时弹性位移和延迟弹性位移之和变化小于10%，这可能表明临床上有足够的弹性性能。
Aim of this study was to investigate the effect of long-time immersion of soft denture liners in 37°C water on viscoelastic properties. Six silicone-based and two acrylic resin-based soft denture liners were selected. Cylindrical specimens were stored in distilled water at 37°C for 6 months. Viscoelastic properties, which were instantaneous and delayed elastic displacements, viscous flow, and residual displacement, were determined using a creep meter, and analyzed with 2-way analysis of variance and Tukey's comparison (α=0.05). Viscoelastic properties and their time-dependent changes were varied among materials examined. The observed viscoelastic properties of three from six silicone-based liners did not significantly change after 6-month immersion, but those of two acrylic resin-based liners significantly changed with the increase of immersion time. However, the sum of initial instantaneous elastic displacement and delayed elastic displacement of two acrylic resin-based liners during 6-month immersion changed less than 10%, which might indicate clinically sufficient elastic performance.
