目的研究处于生长发育期骨性Ⅱ类错随着自然生长颅颌的结构变化及其畸形调整情况,为临床治疗提供参考依据。方法选择放弃治疗的安氏Ⅱ~1类患者28例,平均追踪观察15.4个月,在观察前后头颅侧位片上,测量固定骨性标志点的垂直与矢状方向变化,分析颅颌的变化。结果骨性Ⅱ类错患者,其Ⅱ类关系随着自然生长,并未得到改善,有加重的趋势。结论对骨性Ⅱ类错患者应早期治疗。
Objective To study the structural changes of skeletal Class Ⅱ malocclusion in normal growth and development and its deformity adjustment during growth and development, and to provide a reference for clinical treatment. Methods A total of 28 patients with Class Ⅱ ~ 1 patients who abandoned treatment were selected and followed up for an average of 15.4 months. The changes of vertical and sagittal directions of fixed bony markers were measured before and after the observation. Results In patients with skeletal Class Ⅱ malocclusion, the relationship of type Ⅱ with the natural growth did not improve, with a tendency of aggravating. Conclusions Patients with skeletal Class II malformations should be treated early.
