汉族正常人颜面三维形态特征的测量分析

Three Dimensional Analysis of Normal Facial Morphology with Computer Technique

通过莫尔等高条纹和计算机数字化处理技术,对136名汉族正常(牙合)人面部三维形态结构进行了研究分析,得出了正常人颜面三维特征的参考数据。研究结果还发现,正常(牙合)人男性面部轮廓较突出,口鼻宽度和面高都较女性大,汉族正常(牙合)人面部长宽比例近似黄金分割以及2^(1/2)倍关系,面部器官对称性差值小于1mm。

In this article,136 people with normal occlusion and good facial proportion have beenchosen.The facial morphology and feature of the samples have been analysed and describedin three dimension by using moire topography and digital computer technique.The faceof the male in this group is more convex than that of the female.Some facial proportionsapproach golden section and 2^(1/2)rule.The difference of the linar measurement betweenthe right side and left side is rather small,less than lmm.This information is useful indiagnosis,treatment planning and treatment results evaluation of dentofacial deformities.
