摘　　要：目的应用正畸上颌骨前牵引技术对唇腭裂患者在混合牙列早期出现的骨性反进行阻断治疗，研究上颌骨位置的变化情况。方法比较患者治疗前后的头影测量结果，将治疗后的结果与儿童头测量正常值比较，明确上颌骨位置的变化情况。结果治疗后上颌骨的位置前移变化有显著性（P＜0.01），但与正常值之间也存在一些差异。结论后腭裂患者在混合牙列期，使用正畸方法进行上颌前牵引，可明显促进上颌骨发育.但单纯使用正崎尚不能完全矫正唇腭裂继发的颌骨畸形，必须采用综合治疗。Objective Early interfering orthodontics was used to treat maxillary hyperplasia by face mask and extra-oral bow technique in teenages. The position changes of maxilla after orthodontic treatment were evaluated. Methods The cephlometric variables before and after treatment were measured. Variables after treatment were compared with normal values in children with same ages,and changes of the maxillary position was determind. Results The position of the maxilla after orthopedics was significantly advanced (P<0. 001 ) .but there was still difference from normal va1ues. Conclusion In the peroid of mixed dentition of patients with cleft lip and palate, early orthodontics on maxillary hyperplasia could stimulate maxillary development and growth. remove or improve crossbite,extra-oral bow and face mask were efficient tools for this kind of patients.
