Nonvascularized Free Transport Distraction Osteogenesis to Reconstruct the Mandibular Defect of a Patient With an Ossifying Fibroma: A Case Report.

We report on a case in which trifocal distraction osteogenesis was applied in a patient with a mandibular defect caused by resection of an ossifying fibroma. During the surgical procedure, we accidentally dissected the surrounding periosteal tissue of the left transport completely in the process of transport disc preparation and made the disc into a free bone graft. However, we still used this transport and successfully completed the distraction osteogenesis. The patient's facial and occlusal function were regained after treatment.
