[Prediction system of facial change].
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.


METHODS
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.
