摘　　要：目的 观察骨牵张技术在下颌骨骨折错位愈合二期矫治中的应用。方法采用内置式骨牵张器治疗2例因外伤造成的下颌骨错位愈合及下颌偏斜的患者,骨牵张器每天延长颌骨的1mm,直至下颌骨体部被延长到理想的位置。结果 2例患者受损侧的下颌骨体分别被延长11mm和7mm,无论是咬(牙合)关系还是面部外形均得到明显的改善。结论 骨牵张器为治疗陈旧性颌骨骨折的继发畸形提供了可行且有效的方法。Objective With the increasing frequency of road traffic accidents and injuries caused by violence, the number of case of acquired deformities requiring corrective intervention has also increased. Distraction osteogenesis has been used to correct acquired mandibular deformities, as well as congenital ones. Methods Two patients with mandibular malunion and asymmetry caused by trauma were treated using osteotomy and intraoral distractors. The distractor was activated two a day for a rate of 1. 0mm daily until the desired bone length was achieved. Results The malunion mandibular body of two cases were individually lengthened 11 and 7mm. Clinical examination showed normalization of the malocclusion and improvement of facial contours. Conclusion The distraction osteogenesis is an optional surgical method that can be applied in selected cases with malunion caused by past - trauma.
