摘　　要：目的:运用头影测量评估牙支持式牵张器治疗唇腭裂术后面中部凹陷畸形效果。方法:26例无法采用单纯正颌手术治疗的唇腭裂术后颌面部畸形患者,利用牙支持式牵张器进行骨牵张矫治。牵张前(T1),牵张后(T2)及8周固定期后(T3)均行头影测量。结果:术创正常愈合,牵张过程顺利,达到预期牵张目的。头影测量分析显示上颌前部得到有效向前、向下移动;腭平面延长。结论:牙支持式牵张器可有效治疗唇腭裂术后上颌骨发育不足及软组织量不足的患者。Objective： The aim of this study was to evaluate the cephalometric results of distraction osteogenesis in patients with tooth - borne distractor. Methods： In this study, an individual toothborne distraction device was used for advancement of the maxillary anterior segment. Distraction was performed for 26 patients, according to the specific requirements of the individuals. Cephalometric radiographs were taken before treatment （ T1 ）, after distraction （ T2）, and after consolidation for 8 weeks （33）. Results： Cephalometric analysis revealed that the premaxilla was moved forward and downward and the length of palatal plane increased. Conclusion： These alterations improved the soft tissue profile and solved the space deficiency of the maxilla by using the tooth - borne distractor.
