The peel bond strengths of five impression materials and their tray adhesives to a perforated and non-perforated test surface were measured and the results were compared using a one-way ANOVA and Student Newman Keuls Multiple Range Test at p less than or equal to .05 level of significance. The auto-mix addition reaction silicone material Extrude produced the greatest peel bond strengths on both the non-perforated test surface (10.88 kg/cm2), and on the perforated test surface (15.88 kg/cm2). These bond strengths were greater than those obtained from the polysulphide and polyether materials used in the study. Using the perforated test surface significantly increased the peel bond strength for all the materials tested. It was concluded that in order to achieve the maximum adhesive bond, impression trays should be perforated. The greatest peel bond strengths were obtained using Extrude medium-body impression material.
测量了五种印模材料及其托盘粘合剂与穿孔和未穿孔测试表面的剥离粘结强度，并使用单向方差分析和学生纽曼-基尔斯多重范围检验在显著性水平p≤0.05下比较了结果。自动混合加成反应硅酮材料Extrude在未穿孔测试表面（10.88 kg/cm²）和穿孔测试表面（15.88 kg/cm²）上产生了最大的剥离粘结强度。这些粘结强度大于该研究中使用的多硫化物和聚醚材料所获得的粘结强度。使用穿孔测试表面显著提高了所有测试材料的剥离粘结强度。得出的结论是，为了实现最大的粘结，印模托盘应该穿孔。使用Extrude中稠度印模材料可获得最大的剥离粘结强度。
