本研究的目的是探讨如何在印模材料和托盘之间获得足够和稳定的粘接强度。在自聚树脂柱之间模制印模材料，测量抗拉强度随以下因素的变化：托盘储存时间(1、2、4、7和10天)、胶粘剂干燥时间(0、1、5、10和15分钟)和托盘表面粗糙度(空气磨损、毛刺产生的粗糙度和不处理)。在整个评估期10天内，拉伸粘结强度不受托盘储存时间的影响。对于托盘粘接剂干燥时间，Reprosil和ExaPlant的干燥时间在10min或更短的情况下极低(P<；0.05)，而Imprint 11和Impregium的干燥时间不受干燥时间的影响。乙烯基聚硅氧烷对毛刺产生的粗糙度的粘接强度最高，显著高于空气磨损或不处理的粘结强度(P<；0.05)，而聚醚的粘结强度最低(P<；0.05)。结论是，定制托盘的表面处理应根据印模材料的类型进行调整，以获得最佳的粘接强度。
The aim of this study was to investigate how to achieve sufficient and stable adhesive strength between impression material and tray. Impression materials were molded between autopolymerizing resin columns, and tensile strength was measured as a function of these factors: tray storage time (1, 2, 4, 7, and 10 days), adhesive drying time (0, 1, 5, 10, and 15 minutes), and tray surface roughness (air abrasion, bur-produced roughness, and no treatment). Tensile bond strength was not affected by tray storage time throughout the entire evaluation period of 10 days. As for tray adhesive drying time, Reprosil and Exaimplant yielded extremely low values for drying times of 10 minutes or less (P < 0.05), while Imprint 11 and Impregum were not influenced by drying time. Vinyl polysiloxane achieved the highest adhesive strength with bur-produced roughness, which was significantly higher than with air abrasion or no treatment (P < 0.05), whereas polyether achieved the lowest value with bur-produced roughness (P < 0.05). It was concluded that surface treatment of custom tray should be adapted to the type of impression material used to achieve optimum bond strength.
