摘要: 目的: 应用CBCT进行测量,比较不同颅面型骨性Ⅲ类女性患者不同生长发育阶段颌骨垂直向生长方向的差异。方法: 按照纳入标准选取处于高峰前期,高峰期和高峰后期骨性Ⅲ类女性患者共270例。应用Invivo5.3软件测量相关指标并比较分析。结果: 高角组各测量指标的变化除高峰前期和高峰后期比较及牙合平面角各期间比较以外其余两两比较均有统计学差异;均角组各指标除各期间牙合平面角的比较以及PP-FH角高峰前期、高峰后期比较以外其余两两比较均有统计学差异;低角组各指标变化除三期间牙合平面角两两比较以及PP-FH角高峰前期、高峰后期间比较以外其余两两比较均有统计学差异。结论: 骨性Ⅲ类女性患者生长发育过程中不同骨面型的颌骨垂直向变化间存在较大差异。

Abstract: Objective: To investigate the vertical changes of jaws of skeletal class Ⅲ females with various vertical growth types in different growth stages by CBCT. Methods: A total of 270 females with skeletal class Ⅲ malocclusion with various vertical growth types were randomly selected from CBCT data and divided into pre-growth spurts, peak period, and post-growth spurts. Invivo 5.3 software was used to measure the correlation index. The results were analyzed and discussed. Results: In the high-angle group, the changes were statistically different in addition to the pre and the post peak comparison and the occlusal angle in each period. In the mean-angle group, the changes were statistically different in addition to the pre and the post peak comparison of PP-FH angle and the occlusal angle in each period. In the low-angle group, the changes were statistically different in addition to the pre and the post peak comparison of PP-FH angle and the occlusal angle in each period. Conclusion: In the process of growth and development, the vertical changes of the jaw in class Ⅲ malocclusion females with various facial skeletal types demonstrated significant differences
