The surgery first approach (SFA) and clear aligners technique can address traditional treatment defects, such as prolonged waiting times for surgery and a less desirable facial appearance due to wire aligners. However, the curative effect of the combination remains uncertain. The randomized controlled study aimed to evaluate the skeletal stability of the SFA compared to the conventional orthodontic first approach (OFA), both of which were applied with clear aligners. A total of 74 participants were randomly allocated to two groups: the SFA group (experimental) and the OFA group (control). The skeletal deviation was calculated using reconstruction models from computed tomography scans taken immediately and 6 months after surgery. The largest median deviations were detected in the y-axis of the mandible for both two groups, separately 1.36 mm in the experimental group and 1.19 mm in the control group. Apart from the maxillary yaw dimension ( = 0.005), there were no significant differences between the two groups in terms of linear and angular deviation. The experimental group had an overall treatment time of 18.05 ± 2.53 months, while the control group took 22.83 ± 3.60 months ( < 0.05). Therefore, the combined surgery-first and clear aligners treatment can achieve comparable skeletal stability to the conventional approach, while also saving significant time.
手术优先方法（SFA）和透明矫治器技术可以解决传统治疗的缺陷，例如手术等待时间长以及金属丝矫治器导致的面部外观欠佳。然而，两者联合使用的疗效仍不确定。这项随机对照研究旨在评估与传统正畸优先方法（OFA）相比，SFA的骨骼稳定性，这两种方法均与透明矫治器联合使用。总共74名参与者被随机分为两组：SFA组（实验组）和OFA组（对照组）。使用术后即刻和术后6个月的计算机断层扫描重建模型计算骨骼偏差。两组在下颌骨y轴上均检测到最大的中位数偏差，实验组为1.36毫米，对照组为1.19毫米。除上颌偏航维度外（P = 0.005），两组在直线和角度偏差方面没有显著差异。实验组的总治疗时间为18.05±2.53个月，而对照组为22.83±3.60个月（P<0.05）。因此，手术优先与透明矫治器联合治疗可获得与传统方法相当的骨骼稳定性，同时还能节省大量时间。
