The purpose of this paper is to report a new technique for three-dimensiona
l facial soft-tissue-change prediction after simulated orthognathic surgica
l planning. A scheme for soft tissue deformation, "Computer-assisted three-
dimensional virtual reality soft tissue planning and prediction for orthogn
athic surgery (CASP)", is presented. The surgical planning was based on thr
ee-dimensional reconstructed CT visualization. Soft tissue changes were pre
dicted by two newly devised algorithms: Surface Normal-based Model Deformat
ion Algorithm and Ray Projection-based Model Deformation Algorithm. A three
-dimensional color facial texture-mapping technique was also used for gener
ating the color photo-realistic facial model. As a final result, a predicte
d and simulated patient's color facial model can be visualized from arbitra
ry viewing points.
