Reconstruction of mandibular surgical defects often poses a great challenge to maxillofacial surgeons. Mandibular segmental defects majorly disrupt the occlusion, mastication, and the facial esthetics. Free autografts such as iliac crest and rib; allografts such as three-dimensional, bendable reconstruction plate; and patient-specific implant are some of the techniques that had been employed for the reconstruction of such defects. Nevertheless, in recent times, the most dependable modes of reconstruction are the microvascular fibula reconstruction and transport distraction techniques. Transport distraction osteogenesis (TDO) is a reliable technique without donor-site morbidity especially in the dentate region of the mandible as it provides native bone for rehabilitation. The aim of this article is to report a successful case of TDO to fill the defect in the left body of the mandible secondary to segmental resection of the mandible for keratocystic odontogenic tumor. The technique was successful with a 2-year follow-up period without any potential esthetic compromise.
