本研究的目的是探讨一种新的硅烷偶联剂对各种陶瓷托槽与陶瓷试件的再粘接效果。将不同的陶瓷托槽（Fascination 2、Clarity SL和In-OvationC）分为三组：用新硅烷偶联剂重新粘接、用传统硅烷偶联剂重新粘接或常规粘接作为对照（n = 16）。在万能试验机中用剪切试验计算粘附力。使用粘合剂残留指数评分评价托槽-复合材料-陶瓷界面。采用单因素方差分析进行推断统计。用新的硅烷偶联剂重新粘结导致高剪切粘结强度（SBS;平均值：37.44-41.24 MPa）和陶瓷试样断裂。使用传统硅烷偶联剂重新粘接导致临床上足够的SBS显著（P < 0.001）较低（平均值：20.20-29.92 MPa），陶瓷试样断裂最少。根据其托槽底座设计，定期粘结陶瓷托槽导致临床上足够高的SBS（平均值：17.06-41.56 MPa）。再粘结陶瓷托槽显示陶瓷样本表面有足够的SBS。然而，增加托槽附着力与陶瓷样本表面损坏的风险有关。因此，使用新的硅烷偶联重新粘结的陶瓷托槽应使用替代的脱粘方法谨慎脱粘。
The objective of this study was to investigate the rebonding effect of a new silane coupling agent on various ceramic brackets bonded to ceramic specimen. Different ceramic brackets (Fascination 2, Clarity SL, and In-OvationC) were assigned to three groups: rebonding with new silane coupling agent, rebonding with conventional silane coupling agent, or regular bonding as control (n = 16). Bracket adhesion was calculated with a shear test in a universal testing machine. The bracket-composite-ceramic interface was evaluated using the adhesive remnant index score. One-way analysis of variance was applied for inferential statistics. Rebonding with the new silane coupling agent resulted in high shear bond strengths (SBSs; mean values: 37.44-41.24 MPa) and ceramic specimen fractures. Rebonding with the conventional silane coupling agent resulted in significantly (P < 0.001) lower clinically adequate SBS (mean values: 20.20-29.92 MPa) with the least ceramic specimen fractures. Regularly bonded ceramic brackets resulted in clinically adequate to high SBS (mean values: 17.06-41.56 MPa) depending on their bracket base design. Rebonded ceramic brackets showed sufficient SBS to ceramic specimen surfaces. However, increased bracket adhesion was associated with a risk of ceramic specimen surface damage. Therefore, ceramic brackets rebonded with the new silane coupling should be debonded cautiously using alternative debonding methods.
