Investigations indicate that custom impression trays enhance the accuracy of the fabrication cast. Multiple materials and techniques exist for custom tray fabrication, and variability in the bonding strength of adhesive agents supplied with nonaqueous elastomeric material have been reported. Bonding between two nonaqueous impression materials and two thermoplastic resin tray materials was assessed in this study. Standard tensile specimens were fabricated and the combinations of Hydrotray resin (smooth) with Hydrosil impression material recorded the greatest bonding strength, 797 kPa. Adhesion to resin tray materials was found to vary with material type and surface preparation.
调查表明，定制印模托盘可提高铸造模型制作的准确性。定制托盘制作存在多种材料和技术，并且已有报道称非水性弹性体材料所附带的粘合剂的粘结强度存在差异。本研究评估了两种非水性印模材料与两种热塑性树脂托盘材料之间的粘结情况。制作了标准拉伸试样，Hydrotray树脂（光滑）与Hydrosil印模材料的组合记录到了最大粘结强度，为797千帕。结果发现，与树脂托盘材料的粘结力会因材料类型和表面处理而有所不同。
