[Effect of orthodontic treatment on facial soft tissue in female adult]

In recent years, more and more female adult patients complained the aesthetic problems such as the decline of face fullness during the treatment. In the course of 2-3 years of orthodontic treatment, the age-related change of the facial bone structure in the adult is limited, and therefore, the shape change mainly depends on the change of the soft tissue. In this paper, the factors such as age-increasing factors, the structural factors of the face,the width of the arch and the change of the occlusal height were analyzed to explore the changes of facial soft tissue and related factors in the treatment with a view to providing a reference for clinical application.近年，越来越多的成年正畸女性患者提出矫治过程中面部丰满度下降等美学问题。在为期2~3年的正畸疗程中成年人面部骨骼结构的增龄性变化是有限的，因此，面形的变化主要取决于软组织的改变。本文通过分析正畸治疗过程中面部软组织变化的相关影响因素，如增龄性因素、面部自身的结构因素以及牙弓宽度、咬合高度变化等情况，探讨正畸治疗中面部软组织的变化及其相关影响因素，以期为临床提供参考。.
