This study aimed to evaluate the shear bond strength (SBS) of four bonding agents used to bond metal brackets to zirconia under different storage conditions. Four bonding agents were used [FLC: (Fuji ORTHO LC), XT: (Transbond XT), RUC-SBU: (Rely X Ultimate Clicker Adhesive Resin Cement+Single Bond Universal), and RUC-GBU: (Rely X Ultimate Clicker Adhesive Resin Cement+Gluma Bond Universal)] to bond two types of metal brackets (PT/3M) to zirconia surfaces, and they were stored in water at 37ºC for 24 h or thermocycling for 3,000 cycles. The SBS data of RUC-SBU and RUC-GBU using PT brackets were significantly higher than those of 3M brackets before and after thermocycling. It could be concluded that RUC-SBU and RUC-GBU could offer sufficient bond strength between metal brackets and zirconia for the short term compared with FLC and XT. The design of brackets can significantly affect the bond strength to zirconia.
本研究旨在评估四种粘结剂在不同储存条件下粘结金属托槽至氧化锆的剪切粘结强度（SBS）。使用四种粘结剂 [FLC：（富士乐 Ortho LC）、XT：（Transbond XT）、RUC-SBU：（Rely X Ultimate Clicker 黏结树脂水泥+Single Bond Universal）和 RUC-GBU：（Rely X Ultimate Clicker 黏结树脂水泥+Gluma Bond Universal）] 将两种类型的金属托槽（PT/3M）粘结至氧化锆表面，并将其储存在 37°C 的水中 24 小时或热循环 3000 次。使用 PT 托槽的 RUC-SBU 和 RUC-GBU 的 SBS 数据在热循环前后均明显高于 3M 托槽。可以得出结论，与 FLC 和 XT 相比，RUC-SBU 和 RUC-GBU 在短期内可为金属托槽和氧化锆之间提供足够的粘结强度。托槽的设计会显著影响与氧化锆的粘结强度。
