    Methods:12 Class Ⅱ malocclusion patients(at the average age of 12.3 years) with mesially moved maxillary molar were treated by Distal-Jet appliance. Cephalometic radiographs and dental models were taken and analyzed before and after molar distalization. Results:The treatment time was (4.3±2.8) months.
    方法:应用Distal-Jet矫治器对12例平均年龄为12.3岁,由于上颌磨牙前移所致的安氏Ⅱ类错患者进行治疗,通过远中移动磨牙前后的头影测量分析和模型测量分析评价其远中移动磨牙的疗效。
    Objective:To find out proper therapy for skeletal class II malocclusion,and to investigate etiological mechanism of such malocclusion patients.
    目的:研究我国骨性二类错患者的病因机制是以上颌前突为主,还是下颌后缩为主,根据其病因机制找出合理的治疗方法。
    Results: There was no the maxillary protrusion in nearly 92.9% of skeletal class II malocclusion patients,whereas the mandibular retrusion was found in 67.9% of patients. The difference between the maxillary and mandibular mechanism for skeletal class II malocclusion was statistically significant.
    结果:所研究的骨性二类错患者中92.9%的患者不存在上颌前突病因机制,67.9%的患者存在下颌后缩病因机制,而且这种上、下颌骨病因机制方面的差异性是有显著的统计学意义的。
