摘要/Abstract

摘要： 目的分析Dynamax和Twin block（TBA）治疗中骨龄变化与下颌骨形态变化的相关性及对下颌骨形态的影响。方法设计制作新型Dynamax和TBA,随机应用于临床选择的符合实验组纳入条件的病例各15例,治疗9个月后,去除功能矫治器，观察3个月后收集资料进行测量。结果两实验组与对照组的Co-Gn、Co-Go、Go-Gn之间的差异均有统计学意义（P<0.05）。两实验组骨龄与下颌骨形态变化相关性有统计学意义，对照组没有。结论治疗安氏Ⅱ类1分类患者时，Dynamax可以使下颌骨发生向后的旋转，髁突不但发生垂直向的生长还发生矢状向的生长。骨龄变化与下颌骨的矢状向生长和垂直向生长都有相关性。而TBA主要发生垂直向的生长，骨龄变化与垂直向的变化有相关性。

Abstract: Objective To analyze the correlation between patients′bone age and morphology change of their mandibular bone when treated with Dynamax or TBA. Methods 15 patients selected for each group were treated with new Dynamax or TBA for 9 months.After removing the appliances,we observed for 3 months and then conducted cephalometric analysis of each patient. Results There were significant differences in the Co-Gn,Co-Go,Go-Gn between the two treatment groups and the control group (P<0.05).There was strong correlation between patients′bone age and morphology change of the mandibular bone when treated with Dynamax or TBA(P<0.05),but not in control group. Conclusions The Dynamax could make mandibular circumrotate backward,and promote the condyle growth both vertically and sagittallyin treatment of the Class Ⅱ division 1 patients.And there is correlation between bone age changes and the vertical and sagittal growth of the mandible.The TBA makes the mandible grow vertically.And there is correlation between bone age changes and the vertical growth.

Key words: class Ⅱ division 1 malocclusion, functional appliances, bone age, correlation analysis, cephalometrics
