摘要

背景:本研究旨在探讨使用引导粘接装置(GBD)进行托槽粘接是否足以在体外对拥挤牙进行精确粘接:本研究旨在探讨使用引导粘接装置(GBD)进行托槽粘接是否足以在体外准确地粘接牙列拥挤:方法:将 15 套三维打印的树脂模型分为三组:轻度、中度和重度拥挤。对树脂模型进行扫描并虚拟粘接托槽。生成并 3D 打印相应的 GBD。随后,在牙科人体模型上使用 GBD 将托架粘结到树脂模型上。对粘接托槽的模型进行扫描,并对实际粘接的位置和计划粘接的位置进行比较,以评估可能出现的偏差:结果:各组均未出现即刻粘接失败的情况。粘结时间随拥挤严重程度的增加而延长(P>0.05)。所有组别中几乎所有的线性偏差和角度偏差都分别低于 0.5 毫米和 2°,不同拥挤程度的组别之间没有明显的统计学差异(P > 0.05)。在所有组别中,托槽都倾向于向舌侧偏离,并具有颊侧冠扭矩。轻度和重度拥挤组的托槽有颊中旋转的趋势:GBD为不同拥挤程度的牙体提供了较高的托槽粘结精度,因此有望应用于非拥挤和拥挤牙体。

Is bracket bonding with guided bonding devices accurate enough for crowded dentition?

Background: This research aimed to study whether bracket bonding using guided bonding devices (GBDs) is accurate enough for crowded dentitions in vitro.

Methods: Fifteen three-dimensionally (3D) printed resin model sets were included and divided into three groups: mild, moderate, and severe crowding. The resin models were scanned and virtually bonded with brackets. Corresponding GBDs were generated and 3D printed. Subsequently, the brackets were bonded to the resin models on a dental mannequin using the GBDs. The models with bonded brackets were scanned, and comparisons were made between the positions of the actually bonded and the planned ones to evaluate possible deviations.

Results: There was no immediate bonding failure in any group. The bonding duration tended to increase with crowding severity (P > 0.05). Almost all linear and angular deviations in all groups were below 0.5 mm and 2°, respectively, and no statistically significant difference was found among the different crowding degrees (P > 0.05). In all groups, the brackets tended to deviate lingually and had buccal crown torque. Brackets in the groups with mild and severe crowding showed a tendency for mesiobuccal rotation.

Conclusion: GBDs provide high bracket bonding accuracy for dentitions with different crowding degrees and, thus, could hopefully be applied to uncrowded and crowded dentitions alike.

期刊介绍: The Journal of Orofacial Orthopedics provides orthodontists and dentists who are also actively interested in orthodontics, whether in university clinics or private practice, with highly authoritative and up-to-date information based on experimental and clinical research. The journal is one of the leading publications for the promulgation of the results of original work both in the areas of scientific and clinical orthodontics and related areas. All articles undergo peer review before publication. The German Society of Orthodontics (DGKFO) also publishes in the journal important communications, statements and announcements.
