To recover a mandible defect, the defect is resected and the resulting bone gap can be reconstructed by a fibula graft that shaped similar to the resected part of the mandible. Mandible resection and shaping of the fibula bone is assisted by computer-aided simulation and computer-aided manufacturing (CAS/CAM). In a nutshell, these techniques introduce virtual surgery (CAS) to design an optimal virtual resection and reconstruction plan. These plans can be realized by 3D printing (a CAM technique) into patient-specific resection templates and positioning templates that act as guidance during surgery. However, both surgical experiences and a literature study have pointed out that small differences occur between the virtually planned resection and the obtained resection. These differences may affect patient esthetics and functioning eventually. This study improved the design of the patient-specific resection templates to reduce the differences in the virtually planned resection and the obtained resection, such that an optimal functioning and esthetics of the reconstructed mandible of the patient is achieved.
