This study aimed to evaluate the effect of fence tray matching care (FTMC) in bracket bonding by measuring excess adhesive, as well as linear and angular deviations, and by comparing it with the half-wrapped tray (HWT).
An intraoral scanner was used to acquire data on the maxillary dental arch of a patient with periodontitis.Furthermore, 20 maxillary dental arch models were 3D printed. Using 3Shape, PlastyCAD software, and 3D printing technology, 10 FTMC (method I) and HWT (method II) were obtained. By preoperative preparation, intraoperative coordination, and postoperative measurement, the brackets were transferred from the trays to the 3D-printed maxillary dental arch models. Additionally, the bracket's excess adhesive as well as linear and angular deviations were measured, and the differences between the two methods were analyzed.
Excess adhesive was observed in both methods, with FTMC showing less adhesive (P< 0.001), with a statistical difference. Furthermore, HWT's vertical, tip and torque, which was significantly greater than FTMC (P< 0.05), with no statistical difference among other respects. The study data of incisors, canines, and premolars, showed that the premolars had more adhesive residue and were more likely to have linear and angular deviations.
The FTMC had higher bracket bonding effect in comparison to HWT, and the adhesive residue, linear and angular deviations are smaller. The fence tray offers an intuitive view of the precise bonding of the bracket, and can remove excess adhesive to prevent white spot lesions via care, providing a different bonding method for clinical applications.
本研究旨在通过测量多余粘结剂，并比较线性和角度偏差，评估围栏托盘匹配护理（FTMC）在托槽粘结中的效果，同时与半包裹托盘（HWT）进行比较。
使用口内扫描仪获取一位患有牙周炎患者上颌牙弓的数据。此外，还打印了 20 个上颌牙弓模型。使用 3Shape、PlastyCAD 软件和 3D 打印技术，获得了 10 个 FTMC（方法 I）和 HWT（方法 II）。通过术前准备、术中协调和术后测量，将托槽从托盘转移到 3D 打印的上颌牙弓模型上。此外，还测量了托槽的多余粘结剂以及线性和角度偏差，并分析了两种方法之间的差异。
两种方法均观察到多余粘结剂，FTMC 显示的粘结剂较少（P<0.001），存在统计学差异。此外，HWT 的垂直、尖端和转矩明显大于 FTMC（P<0.05），但在其他方面没有统计学差异。切牙、尖牙和前磨牙的研究数据表明，前磨牙的粘结剂残留更多，更容易出现线性和角度偏差。
与 HWT 相比，FTMC 具有更高的托槽粘结效果，且粘结剂残留、线性和角度偏差更小。围栏托盘提供了托槽精确粘结的直观视图，并可以通过护理去除多余的粘结剂，以防止出现白斑病，为临床应用提供了一种不同的粘结方法。
