Abstract

Abstract: Objective: To analyze the advantages and disadvantages of digital guiding template for accurate reconstruction of maxillary defects, and to evaluate its clinical effect. Methods: Retrospective analysis was performed from March 2014 to June 2019, including 16 cases of maxillary defect reconstruction. All patients used preoperative virtual surgery plan to design, and make personalized surgical guiding templates by following 3D printing. The pre-bending and shaping of titanium mesh and plate were based on the printed 3D model. All procedures during operation were strict according to the guiding template, and postoperative verification used fusion-images technology to evaluate the postoperative effect. Results: 16 cases of vascularized free bone flap survived successfully, and the reconstruction effect was basically consistent with the preoperative design. After follow-up, patients were observed with satisfactory appearance, good bone healing, normal occlusal relationship, and no serious complications in the donor area. Conclusion: The personalized guide plate made by virtual operation system can greatly reduce the time of adjusting and grinding bone mass, the time of determining the position of bone segment, and the time of reducing the difficulty of operation, and shorten the operation time and the injury of donor area.
