Abstract: 【Abstract】〓Objective〓To summarize the application of omputer-aided design/computer-aided manufacturing (CAD/CAM) combined with rapid prototyping manufacturing technology (RPMT) in the reconstruction of midfacial fractures. Methods〓Eighteen sujects suffered with midfacial fractures and treated by CAD/CAM combined with RPMT were collected. Befort operation,.all the subjects were accepted maxillofacial CT scan, mimics software for three-dimensional (3D) reconstruction of CT scan data, and get the 3D model of virtual repair using mirror image technology, making real fracture 3D model. This model was used to guide the reduction and fixation of midfacial fractures. Results〓Patients were followed up for 3-24 months, and achieved anatomic reconstruction of fractures. The outcome after treatment was satisfied esthetically and functionally. Conclusions〓The use of CAD/CAM combined with RPMT is effective for complicated midfacial fractures, which could shorten the operation time and reduce operation risk, increase the repositioning precisely, and help to communicate between doctors and patients.
