摘　　要：应用计算机图像分析系统和测量技术，对19名正常者，在正中位时，颌面部与垂直距离相关的33个测量项目进行测量分析，获得了21～24岁年龄组各测量指标的参考值，并进行了相关的资料比较。结果发现：测得的有关测量项目的正常值与其他文献的报道值接近，而且发现在正常垂直距离时，本组研究对象鼻、唇、颏突度不如白种人明显，上下唇位也较为前位。The rehabilitation of vertical dimension of occlusion (VDO)exactly is one of the most important procedure for dental prosthesis in the field of prosthodontics. In this study, total of 19 subjects with normal range occlusion were selected. We measured 33parameters relating to VDO of their facial soft tissue at intercusping position, with the technique of digital imaging analysis. The results as follows:we established a set of normal values of facial soft tissues parameters,which is suitable for the age group of 21-24 years old.It would provide an objective criterion for the rehabilitation of VDO. Also the normal values in this studies had been compared with other studies, and it showed that the values of some parameters in our study, such as CH-CH', nasolabial angle and labiomental angle were very close to other data. Furthermore,it was found that both the position of the upper lip and the lower lip of the subjects were more anterior to that of white men, while the degrees of nasolabial and labiomental convexity were less obvious.
