When performing mandibular reconstructive surgery, differences between the curve of the mandible and straight bone graft often affect the suiting of the mandible reconstruction plate, making the suiting of the bone graft to the mandible difficult. Poor plate-to-bone suitability affects postoperative mastication, leading to a marked decrease in the postoperative quality of life. In response to this problem, we used 3-dimensional models of the donor bone and mandible to reproduce the shape of the reconstructed mandible before surgery. Based on this model, we then used surgical measures, such as creating a surgical guide plate, to reproduce the curvature of the mandibular reconstruction plate and mandibular position and occlusion. Of thirteen patients who underwent mandibular reconstruction using this method at our hospital, evaluation was possible for ten patients. These patients underwent evaluation of functions, including masticatory performance and occlusal force. Results showed that masticatory function was maintained at a high level using this method, indicating a good bone suitability.
