OBJECTIVES
More time is often needed for adult orthodontic patients compared with juvenile counterparts due to lower tissue vitality. In some cases, the prolonged orthodontic treatment may cause a series of problems, such as enamel demineralization, dental caries, periodontitis and root resorption. Therefore, we aimed to accelerate tooth movement to avoid various adverse reactions by 3D-printing assisted micro-osteoperforations (MOPs) in difficult orthodontics cases.
METHODS
Twenty-eight adult patients (28.3 ± 3.4 years) with slow tooth movement after extraction of bilateral maxillary first premolars were included. The scheme of 3D-printing assisted MOPs was designed to perform bone punctures in the mesial and distal sides of canines.
RESULTS
The average speed of the retraction of canines was 1.02 ± 0.41 mm per month after MOPs and significantly faster than that before the MOPs, 0.34 ± 0.16 mm per month (P < 0.05). Moreover, the evaluation of side effects including root resorption, periodontal damage did not reach statistical difference and pain level was acceptable generally.
CONCLUSION
MOPs assisted by 3D-printing could significantly accelerate tooth movement while achieving greater precision, without notably increasing side effects.

目的
由于组织活力较低，成人正畸患者通常比青少年患者需要更多时间。在某些情况下，延长的正畸治疗可能会导致一系列问题，如牙釉质脱矿、龋齿、牙周炎和牙根吸收。因此，我们旨在通过3D打印辅助微骨穿孔术（MOPs）来加速牙齿移动，以避免在复杂正畸病例中出现各种不良反应。
方法
纳入28例双侧上颌第一前磨牙拔除后牙齿移动缓慢的成年患者（28.3±3.4岁）。3D打印辅助MOPs方案设计为在尖牙的近中和远中侧进行骨穿刺。
结果
MOPs术后尖牙平均每月内收速度为1.02±0.41mm，明显快于MOPs术前的0.34±0.16mm/月（P<0.05）。此外，包括牙根吸收、牙周损伤在内的副作用评估未达到统计学差异，疼痛程度总体可接受。
结论
3D打印辅助的MOPs可以显著加速牙齿移动，同时实现更高的精度，且不会显著增加副作用。
