摘要

目的: 评估使用不同附着结构的透明矫治器进行牙齿旋转运动的准确性:评估使用不同附着结构的透明矫治器进行牙齿旋转运动的准确性:这项回顾性研究分析了接受隐适美治疗的 89 名患者的 212 颗牙齿。在虚拟治疗计划(ST1)和第一个治疗阶段(ET1)之后,对数字模型进行了分析,以评估有效的临床旋转运动。门牙、犬齿和双尖牙的旋转移动是通过 Clincheck 移动表中的数据进行测量的。将 ST1 和 ET1 进行比较,以确定实际达到的旋转运动(ST1-ET1)。对牙齿上有无附着物(矩形或优化)进行分析。使用 Kruskal-Wallis 检验比较了不同附着类型的旋转运动准确性。以准确性为因变量,以牙齿类型、性别和年龄为预测因素,进行了多元线性回归:结果:优化附着体的中位准确率最高(70%),其次是矩形附着体(65%)和无附着体(63%),三者无显著差异(p = .5)。不同年龄组、性别或牙齿类型之间没有明显差异。基线准确率为 68.62%(95% CI:56.03-81.20,p 2 为 0.046,调整后的 R2 为 0.003,表明所解释的变异最小:结论:在透明矫治器上增加附着配置可以提高旋转的准确性,但效果并不显著。需要进一步改进这些配置,以提高矫治器的性能。

Accuracy of clear aligners in the orthodontic rotational movement using different attachment configurations

Objective

To evaluate the accuracy of dental rotational movements using clear aligners with different attachment configurations.

Materials and Methods

This retrospective study analysed 212 teeth from 89 patients undergoing Invisalign treatment. Digital models were analysed after the virtual treatment plan (ST1) and after the first treatment phase (ET1) to evaluate the effective clinical rotational movement. The rotational movements of incisors, canines, and bicuspids were measured using data from the Clincheck Movements Table. ST1 and ET1 were compared to determine the actual rotational movement achieved (ST1-ET1). The presence or absence of attachments (rectangular or optimized) on teeth was analysed. The accuracy of rotational movements among attachment types was compared using the Kruskal-Wallis test. Multiple linear regressions were conducted with accuracy as the dependent variable and tooth type, gender, and age as predictors.

Results

Optimized attachments had the highest median accuracy (70%), followed by rectangular (65%), and without attachment (63%), with no significant differences (p = .5). There were no significant differences across age groups, genders, or tooth types. Baseline accuracy was 68.62% (95% CI: 56.03–81.20, p < .001). Age was a significant predictor (estimate = −0.30, 95% CI: −0.58 – −0.03, p = .032), indicating decreased accuracy with increasing age. The model's R2 was 0.046, with an adjusted R2 of 0.003, indicating minimal variance explained.

Conclusion

The addition of attachment configurations to clear aligners improves rotational accuracy, but not significantly. Further advancements in these configurations are needed to enhance the performance of the aligners.

期刊介绍: Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions. The objective of the journal is to facilitate effective communication between the research community and practicing clinicians. Original papers of high scientific quality that report the findings of clinical trials, clinical epidemiology, and novel therapeutic or diagnostic approaches are appropriate submissions. Similarly, we welcome papers in genetics, developmental biology, syndromology, surgery, speech and hearing, and other biomedical disciplines related to clinical orthodontics and normal and abnormal craniofacial growth and development. In addition to original and basic research, the journal publishes concise reviews, case reports of substantial value, invited essays, letters, and announcements. The journal is published quarterly. The review of submitted papers will be coordinated by the editor and members of the editorial board. It is policy to review manuscripts within 3 to 4 weeks of receipt and to publish within 3 to 6 months of acceptance.
