Mandibular resection may be an essential part of treatment for benign or malignant conditions such as trauma, osteomyelitis or osteoradionecrosis, keratocystic tumors or oral cancer. Once mandibular continuity is lost, the large defects can be challenging to reconstruct, and this is due to both functional and aesthetic reasons. Several options are available for reconstruction, including vascularized bone grafts combined with load-bearing reconstruction plates. Well-established osseous donor sites providing sufficient bone length include fibula, iliac crest and scapula flaps. The vascularized free fibula flap is often the first choice for mandibular reconstruction. With the development of patient-specific functionalized implants (PSFI), another possibility to achieve a true-to-origin contour of resected bone has been established. The accuracy of reconstruction plates created by computer-aided design/computer-aided manufacturing (CAD/CAM) or selective laser melting (SLM) is superior to the manually bent reconstruction plates. CAD/CAM or SLE plates are also superior in terms of strength and intraoperative positioning, when compared to manually bent plates, which are important parameters for a tailored reconstruction. Based on our results, the use of PSFIs in the reconstruction of mandibular segmental defects may contribute to a better clinical outcome.
