The purpose of this investigation was to evaluate the tensile bond strength of one type of impression material adhesive to three different custom tray materials: one autopolymerizing (Fastray) and two light-polymerizing (Triad and Extoral). The effect of different surface treatments was evaluated for each of the materials. No significant difference in impression material adhesive mean tensile bond strengths was exhibited for any of the materials as the result of variations in the surface treatment. It was observed that the Triad tray material groups, with different surface treatments, exhibited significantly higher impression material adhesive mean tensile bond strengths than the autopolymerizing tray resin and the Extoral light-polymerizing material.
一种自凝材料（Fastray）和两种光固化材料（Triad和Extoral）。对每种材料评估了不同表面处理的效果。由于表面处理的变化，任何一种材料的印模材料粘合剂平均拉伸粘结强度均未显示出显著差异。观察到，经过不同表面处理的Triad托盘材料组的印模材料粘合剂平均拉伸粘结强度明显高于自凝托盘树脂和Extoral光固化材料。
