Abstract

The purpose of this study was to determine the influence of plasticizer content on the tensile bond strength of heat-cured acrylic soft denture liners to a denture base resin. Differences among materials were significant, except for 100 wt% Dibutyl Sebacate (DBS) and 80 wt% DBS of tensile bond strength. The bond strength of all materials to the denture base increased with an increase in thermal cycles significantly except for 40 wt% DBS. The tensile bond strength of soft denture liners to the denture base resin significantly decreased with an increase of plasticizer contents. Differences were found among the difference plasticizer contents in failure types between the denture base resin and soft denture liners. The results suggest that the tensile bond strengths of heat-cured acrylic soft denture liners to the denture base resin were lower with an increase in plasticizer content.

摘要

本研究的目的是确定增塑剂含量对热固化丙烯酸类软质义齿衬垫与义齿基托树脂之间拉伸粘结强度的影响。材料之间的差异具有显著性，但100 wt%癸二酸二丁酯（DBS）和80 wt% DBS的拉伸粘结强度除外。除40 wt% DBS外，所有材料与义齿基托的粘结强度均随热循环次数的增加而显著提高。软质义齿衬垫与义齿基托树脂之间的拉伸粘结强度随增塑剂含量的增加而显著降低。在义齿基托树脂和软质义齿衬垫之间的失效类型中，不同增塑剂含量之间存在差异。结果表明，热固化丙烯酸类软质义齿衬垫与义齿基托树脂之间的拉伸粘结强度随增塑剂含量的增加而降低。
