【Abstract】 Objective: To investigate the application of digital technology and 3 D printing in preoperative assessment and planning of internal fixation surgery for jawbone fracture. Methods: CT data of jaw fracture cases were collected and imported into Mimics for reconstruction. Digital design was used to simulate the internal fixation of jaw fractures. The fracture model was printed with a 3 D printer and the 3 D model was digitally simulated with an internal fixation protocol. The effects of internal fixation were compared between the virtual surgery and the simulated surgery based on the 3 D models. Results: The effects of internal fixation in the simulated surgery based on the 3 D models were consistent with those of the virtual surgery. Conclusion: Digital design combined with 3 D printing technology can effectively improve the effect of internal fixation of jaw fracture.更多还原
