摘要

导言：数字化治疗计划的发展促进了对更快和隐形正畸治疗的需求，从而使透明矫治器的使用越来越多。本研究旨在评估正畸医生与 3Shape Design Service® 工程师进行的数字化正畸设置的可靠性。材料和方法2022 年 10 月至 2023 年 5 月在布列塔尼医院进行了一项单中心横断面观察性研究。所有符合纳入标准并愿意参与的患者均被纳入研究。口内扫描用于使用 Ortho System® 软件创建治疗设置，由正畸医生和 3Shape® 工程师共同完成。首要目标是比较两组患者的牙齿移动情况（旋转、内收、外翻、颊舌侧倾斜、翻转、中髁侧平移和颊舌侧平移）。次要目标包括移位牙齿的数量、所需的矫治器、近侧釉质减少以及所安置的附着体数量。两组患者在牙齿移位方面存在明显的统计学差异，工程师的牙齿移位幅度更大，包括脱位（4.9 ± 2.6 vs. 3.7 ± 2.3）、倾倒（0.79 ± 0.69 vs. 0.26 ± 0.44）、颊舌侧移位（0.40 ± 0.26 vs. 0.08 ± 0.11）和中远侧移位（0.31 ± 0.20 vs. 0.20 ± 0.17）。除了3Shape组的牙齿移位数（15.32 ± 5.21 vs. 9.68 ± 4.82）更高外，其他次要指标均无明显差异。讨论虽然工程师的数字化设置显示出更明显的牙齿移动，但对轻度错合畸形治疗的实际影响很小。结论对于轻度错颌畸形，将设置工作外包给 3Shape 工程师可以替代正畸医生的诊室设置。然而，对于更复杂的错合畸形，还需要进一步的研究来评估设置的可靠性。

Comparison of dental movements in digital setups created by orthodontists and “3shape design service®” engineers: A cross-sectional study

Introduction

The demand for faster and invisible orthodontic treatments has led to the increased use of clear aligners, facilitated by advancements in digital treatment planning. This study aims to evaluate the reliability of digital orthodontic setups performed by orthodontists compared to those by 3Shape Design Service®engineers.

Material and methods

A monocentric, cross-sectional observational study was conducted at Bretonneau Hospital from October 2022 to May 2023. All patients meeting the inclusion criteria and willing to participate were included in the study. Intraoral scans were used to create treatment setups using the Ortho System® software, performed by both orthodontists and 3Shape® engineers. The primary objective was to compare the dental movements (rotation, intrusion, extrusion, buccolingual inclination, tipping, mesiodistal translation and buccolingual translation) between the two groups. Secondary objectives included the number of teeth displaced, aligners needed, interproximal enamel reduction and number of attachments placed.

Results

Nineteen patients with mild to moderate malocclusion were included. Statistically significant differences were found in tooth displacements between the two groups with engineers executing greater dental movements for derotation (4.9 ± 2.6 vs. 3.7 ± 2.3), tipping (0.79 ± 0.69 vs. 0.26 ± 0.44), bucco-lingual (0.40 ± 0.26 vs. 0.08 ± 0.11) and mesio-distal translations (0.31 ± 0.20 vs. 0.20 ± 0.17). Secondary measures showed no significant differences except for the number of teeth displaced (15.32 ± 5.21 vs. 9.68 ± 4.82), which was higher in the 3Shape group.

Discussion

While digital setups by engineers showed more significant tooth movements, the practical impact on mild malocclusion treatment was minimal. This study highlights the need for precise treatment objectives and consideration of overcorrection practices.

Conclusion

For mild malocclusions, outsourcing setups to 3Shape engineers can be an alternative to in-office setups by orthodontists. However, further studies are needed to evaluate setup reliability for more complex malocclusions.
