ABSTRACT
Computer tomography scanning was performed in 16 patients with mandibular angle hypertrophy before and after surgery. The imaging data of patients were recorded in three-dimensional reconstruction software (Mimics 10.0), and found the most appropriate surgery plan through simulating different surgical procedures. The geometry character indexes of the face were compared between before and after surgery, and then the results were analyzed. We got intuitive, accurate three-dimensional reconstruction graphs, simulation of surgery procedures, and calculation of difference in the geometry character index of face in all cases. The bone width of mandibular angle shortened (7.69?.89) mm; the soft tissue width of mandibular angle shortened (5.13?.19) mm; the both gonial angle increased (5.68?.43)?and (5.91?.66)? respectively. Applied to actual surgery procedure,the operation time shortened and precision of operation was improved. Results demonstrated that Computer three-dimensional reconstruction and computer simulation techniques is beneficial to reveal the variational regularity of bone and soft tissue, which is a good aided method in stimulation of surgery and choice of surgery plan.
