摘要：

目的 探究东北地区正常牙合成人垂直趋向生长与平均生长骨面型的生长特征。方法 2008年5—10月在东北地区正常牙合成人资料库中，选择正常牙合成人平均生长骨面型42人（男21人，女21人），垂直趋向生长23人（男12人，女11人），对其头颅侧位X线片进行头影测量分析。 结果 东北地区正常牙合男性垂直趋向生长骨面型后面高与平均生长骨面型比较，差异有统计学意义（P < 0.05）。东北地区正常牙合女性垂直趋向生长骨面型上颌长与平均生长骨面型比较，差异有统计学意义（P < 0.05）。结论 东北地区正常牙合成人垂直趋向生长骨面型者有自己的生长特征。

Abstract:

Objective To explore the characteristics of the vertical trend growth pattern of adults with normal occlusion in northeastern China. Methods Select an average growth of 42 cases（male 21，female 21） and the vertical trend of 23 cases （male 12，female 11）. The lateral cephalometric radiographs were traced on acetate sheets with sharp 4H pencils. Identify landmarks and measure indexes of Wylie analysis with traced protractor template. Results The difference of the height of S-Go of male had statistical significance（P < 0.05）between the vertical trend growth pattern and the average in northeastern China. Female difference of the length of maxilla had statistical significance （P < 0.05）. Conclusion The vertical trend of the growth has its own growth characteristics.

Key words: northeastern China, normal occlusion, the vertical trend growth pattern
