| 摘 要： | 目的 研究口外弓结合滑动杆推上颌第一磨牙远移矫治安氏Ⅱ类亚类错(牙合)畸形磨牙远移的变化。方法 10例患者进行推上颌第一磨牙远移治疗前、后的X线头影对比研究。平均治疗101天,其测量值作统计学t检验。结果 磨牙均被纠正为安氏Ⅰ类关系。上颌磨牙平均远移3.78±2.02mm(P<0.01),同时伴有上颌磨牙的远中倾斜,平均3.2°±1.4°;下颌磨牙平均近移0.99±0.63mm(P<0.01)。给论 纠正磨牙关系为Ⅰ类关系有赖于一定比率的下颌磨牙近移。SNA角、SNB角、Y轴和PP/MP角的相对稳定,对颌骨无影响。

| Abstract: | Objective To study the varity of molars distal movement on treating patients with subdivision class a! malocclusion by face- bow binding sliding - jin. Methods 10 patients of subdivision class a! malocclusion were treated. After patients treatment for 96. 37 days, the pre - trentment and the por - treatment vanties of molar movement were measured with t test. Results The reults of X- ray analysis found that the masillary molar of experiment side has been moved distally average 3.78 mm |
