[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.
