摘要

目的:研究操作者的临床经验是否以及如何影响体外使用引导粘接装置(GBD)的托槽放置准确性:研究操作者的临床经验是否以及如何影响体外使用引导粘接装置(GBD)放置托槽的准确性:将五个树脂模型与托槽进行虚拟粘接,并生成和三维打印相应的 GBD。包括 3 名牙科学生、3 名正畸专业学生和 3 名正畸医生在内的 9 名操作人员在牙科人体模型上使用 GBD 在树脂模型上粘接托槽。粘结托槽后,对模型进行扫描,比较托槽的实际位置和设计位置:结果:没有出现立即脱钩的情况。正畸医生粘接托槽的时间(22.36 分钟)明显短于牙科学生(24.62 分钟;P < .05)。牙科学生组的托槽倾向于偏向颊侧。正畸专业学生组的线性偏差最小,但不同临床经验的操作者之间没有发现明显差异(P > .5)。各组的所有线性偏差和角度偏差分别小于 0.5 毫米和 2°:结论:临床经验与使用GBD的粘接准确性呈正相关,尤其是在颊舌侧维度。经验不足也会导致粘接时间延长。然而,粘接的准确性在临床上总体上是可以接受的。

Does clinical experience affect the bracket bonding accuracy of guided bonding devices in vitro?

Objectives: To study whether and how the clinical experience of the operator affects the accuracy of bracket placement using guided bonding devices (GBDs) in vitro.

Materials and methods: Five resin models were bonded virtually with brackets, and the corresponding GBDs were generated and three-dimensionally printed. Nine operators, which included three dental students, three orthodontic students, and three orthodontists, bonded the brackets on the resin models using GBDs on a dental mannequin. After being bonded with brackets, the models were scanned, and the actual and designed positions of the brackets were compared.

Results: There was no immediate debonding. The orthodontists spent a significantly shorter time (22.36 minutes) in bracket bonding than the dental students (24.62 minutes; P < .05). The brackets tended to deviate to the buccal side in the dental student group. Linear deviations tended to be smallest in the orthodontic student group, but no significant difference was found among operators with different clinical experience (P > .5). All linear and angular deviations in each group were under 0.5 mm and 2°, respectively.

Conclusions: Clinical experience was positively related to the bonding accuracy using GBDs, especially in the buccolingual dimension. Inexperience also led to longer bonding duration. However, bonding accuracy was clinically acceptable in general.
