摘要：

目的探讨环境和遗传因素在混合牙列期对软组织H平面的影响，为确立牙齿的正确矫治计划提供理论依据。方法测量6～12岁183对双生子女童的头颅侧位片，利用双生子法得出生长发育过程中环境和遗传因素对颅面软组织侧貌产生的影响。结果 H1软组织鼻根点、H2鼻顶点、H4鼻下点、H9下唇凹点、H10软组织颏下点均能够检测到受环境因素的影响，而H9下唇凹点受环境和遗传因素的双重影响。结论上下唇部可以检测出受环境因素的影响，下唇凹点受到环境和遗传因素的共同影响。

Abstract:

Objective To study the relative effects of environment and genes on the soft tissue H plane during the mixed dentitions, and to provide theoretical evidence to establish the correct teeth treatment plan. Methods The lateral cephalograms of one hunded and eighty-three female twins were studied. The environmental and genetic effects were analyzed on soft tissue profile by twin method . Results The influence of environmental factors was detected by measurement items of soft tissue nasal roots (H1), nasal vertex (H2),subnasal point (H4),lower lip pits（H9）, and soft tissue chin point (H10). The influence of environmental and genetic factors was detected by measurement items of lower lip pits（H9). Conclusion The upper and lower lips are detected to be influenced by environmental factors, whereas the lower lip pits are mainly by the environmental and genetic factors.
