The face is a most important part of our features because of the importance it plays in communication. This paper looks at a means of defining what is normal and also what is beautiful. The face is a three-dimensional object and therefore needs to be measured in three dimensions. This paper describes an optical surface scanning system which has been used to analyze the faces of 40 normal patients with a Class I occlusion and also the faces of 30 models from the No. 1 Agency in London. The scans of each group has been separated into males and females, and the faces averaged to give an average normal male face and an average normal female face, an average model male face and an average model female face. These faces have then been compared by a special registration programme which enables the observer to compare the faces in three dimensions and record the amount of difference between them. The value of the system in forensic science for the identification of profiles in photographs is also illustrated as is its use in the building up of the soft tissues over the skull. The importance of which parts of the face are genetically determined has also been looked at by special shape analysis programmes and these are described.
由于面部在交流中所起的重要作用，它是我们容貌中最重要的部分。本文探讨了一种定义正常及美丽标准的方法。面部是一个三维物体，因此需要从三个维度进行测量。本文描述了一种光学表面扫描系统，该系统已被用于分析40名具有I类咬合的正常患者的面部，以及来自伦敦第一模特经纪公司的30名模特的面部。每组扫描数据按性别分开，对面部进行平均处理，得出平均正常男性面部、平均正常女性面部、平均模特男性面部和平均模特女性面部。然后，通过一个特殊的配准程序对这些面部进行比较，该程序使观察者能够在三个维度上比较面部，并记录它们之间的差异量。该系统在法医学中用于识别照片中的面部轮廓的价值也得到了说明，以及它在颅骨软组织建模中的应用。通过特殊的形状分析程序，还研究了面部哪些部分是由基因决定的，本文对此进行了描述。
