Three-dimensional simulation of facial change in a patient with severe facial deformity is very effective in not only determining a treatment plan but also in obtaining informed consent. The purpose of this presentation was to introduce the outline of our prediction system of facial change and its preliminary clinical application. (Outline of this system) This system is composed of the following three parts: Input: Three-dimensional digitized data from modified Moire Topography and coloring data of the face taken by the three-dimensional photographing appliance.
Reconstruction of colored simulation model and transformation by host computer with 32 bit CPU. Output: Display of full-colored simulation model by three-dimensional graphics (Results of clinical application) 1. Three-dimensional reconstructed graphics were well accepted for clinical use, especially for the prediction in orthognathic surgery. 2. Compared with other systems, the following advantages were found: a) Simplified digitizing system using the CCD camera b) Total access time, from initial data input to display of computed picture, was about 20 minutes c) Accurate reproducibility of facial form and color vision.
对严重面部畸形患者面部变化进行三维模拟，不仅在确定治疗方案方面非常有效，而且在获得知情同意方面也很有效。本报告的目的是介绍我们的面部变化预测系统的概况及其初步临床应用。（该系统的概况）该系统由以下三个部分组成：输入：来自改良莫尔条纹地形图的三维数字化数据以及由三维摄影设备拍摄的面部着色数据。
彩色模拟模型的重建以及由32位CPU主机进行的变换。输出：通过三维图形显示全彩色模拟模型（临床应用结果）1. 三维重建图形在临床应用中得到了很好的认可，特别是在正颌外科手术的预测方面。2. 与其他系统相比，发现了以下优点：a）使用CCD相机的简化数字化系统b）从初始数据输入到显示计算图像的总访问时间约为20分钟c）面部形态和颜色视觉的准确再现性。
