摘　　要：目的研究上颌前方牵引加舌刺矫治替牙期伴舌习惯的高角骨性Ⅲ类错的临床疗效。方法 7例适应证患者接受前牵引加舌刺的矫形治疗,采用X线头影测量技术分析软硬组织矫治前后的改变。结果所有患者前牙建立正常的覆盖,正常或稍浅的覆。上颌骨向前发育,下颌骨后退,下颌平面角无明显增大,上下颌骨间不调改善,鼻唇角减小,面型明显改善。结论使用上颌前方牵引加舌刺能有效治疗替牙期的伴舌习惯的高角骨性Ⅲ类错。Objective To investigate the clinical effects of maxillary protraction and tongue crib on the treatment of skeletal class III high angle with the tongue thrust habit cases. Methods Using cephalometric analysis technique to analyze the seven patients＇ soft and hard tissue changes after maxillary protraction and tongue crib treatment. Results All the patients got the normal anterior teeth overjet, normal or slightly shallow overbite. Maxilla grew forward, mandible moved back. The mandibular plane angle had no significant change.
