Abstract

The effect of different curing cycles on the tensile strength of the bond between one brand of cross-linked acrylic resin teeth and three heat cured denture base acrylic resins was tested. There were differences in the tensile bond strength between the three heat cured denture base acrylic resins and the three curing cycles used. The bond strength of the acrylic resin denture base material made by the same manufacturer as the cross-linked acrylic resin denture teeth was higher. The bond strength following the short cycle was lowest in all cases, individual differences between curing cycles failed to reach statistical significance.

摘要

测试了不同固化周期对某一品牌交联丙烯酸树脂牙与三种热固化义齿基托丙烯酸树脂之间粘结拉伸强度的影响。三种热固化义齿基托丙烯酸树脂与所采用的三种固化周期之间的拉伸粘结强度存在差异。与交联丙烯酸树脂义齿牙由同一制造商生产的丙烯酸树脂义齿基托材料的粘结强度更高。在所有情况下，短周期后的粘结强度最低，固化周期之间的个体差异未达到统计学显著性。
