title: [The evaluation of computer-aided simulating system in orthognathic surgery]
abstract: OBJECTIVE: The purpose of this study is to evaluate the reliabillty of computer-aided simulating system for orthognathic system. METHODS: 24 cases with dentofacial deformities were undergone treatment of orthognathic surgery.The presurgical cephalograms and profiles were input to the computer and were digitized.The simulated profiles and cephalometric analysis were obtained by the simulating system,and computer with the actual posttreatment cephalograms. RESULTS: The prodicted and actual posttreatment soft tissue line drawings were quite similar in all areas except for the lower lip region. CONCLUSION: In all cases,the actual images were judged more esthetic than the predicted images. It allayed the fears that the computer generated predictions were unrealistically and ideal.
