目的：治疗持续时间是正畸患者抱怨最多的事情之一。为了缩短治疗时间，引入了一种通过牵张成骨快速犬缩回的新技术。本文介绍了牙槽牵引对牙面结构的影响。材料：研究样本由 10 名成长中或成年受试者的 20 颗上颌尖牙组成（平均年龄，16.53 岁；范围，13.08-25.67 岁）。拔除第一颗前磨牙，进行牙槽骨牵引手术，并放置定制的口腔内刚性齿载牵引装置。犬牙在 8 至 14 天内以每天 0.8 毫米的速度快速移动到拔牙部位。结果：平均 10.05 (+/- 2.01) 天即可实现尖牙完全回缩。锚固齿能够承受回缩力，同时锚固损失最小。牙槽骨牵引结束时，尖牙倾斜度的平均变化为 13.15 度+/- 4.65 度，前脸高度和下颌平面角增加，覆盖显着减少。没有观察到并发症的临床和放射学证据，例如牙根折断、牙根吸收、强直、牙周问题和软组织裂开。手术后患者有轻微至中度的不适。结论：牙槽骨牵引技术是一种创新方法，可将正畸治疗整体时间缩短近50%，且对周围结构无不良影响。
Purpose: Duration of treatment is one of the things orthodontic patients complain about most. To shorten treatment time, a new technique of rapid canine retraction through distraction osteogenesis was introduced. The effects of dentoalveolar distraction on the dentofacial structures are presented in this article. Material: The study sample consisted of 20 maxillary canines in 10 growing or adult subjects (mean age, 16.53 years; range, 13.08-25.67 years). First premolars were extracted, the dentoalveolar distraction surgical procedure performed, and a custom-made intraoral, rigid, tooth-borne distraction device was placed. The canines were moved rapidly into the extraction sites in 8 to 14 days, at a rate of 0.8 mm per day. Results: Full retraction of the canines was achieved in a mean time of 10.05 (+/- 2.01) days. The anchorage teeth were able to withstand the retraction forces with minimal anchorage loss. The mean change in canine inclination was 13.15 degrees +/- 4.65 degrees, anterior face height and mandibular plane angle increased, and overjet decreased significantly at the end of dentoalveolar distraction. No clinical and radiographic evidence of complications, such as root fracture, root resorption, ankylosis, periodontal problems, and soft tissue dehiscence, was observed. Patients had minimal to moderate discomfort after the surgery. Conclusions: The dentoalveolar distraction technique is an innovative method that reduces overall orthodontic treatment time by nearly 50%, with no unfavorable effects on surrounding structures.
