[Clinical analysis of 12 cases of orthognathic surgery with digital computer-assisted technique].

PURPOSE: This study was to investigate the effect of the digital computer-assisted technique in orthognathic surgery. METHODS: Twelve patients from January 2008 to December 2011 with jaw malformation were treated in our department. With the help of CT and three-dimensional reconstruction technique, 12 patients underwent surgical treatment and the results were evaluated after surgery. RESULTS: Digital computer-assisted technique could clearly show the status of the jaw deformity and assist virtual surgery. After surgery all patients were satisfied with the results. CONCLUSIONS: Digital orthognathic surgery can improve the predictability of the surgical procedure, and to facilitate patients' communication, shorten operative time, and reduce patients' pain.
