ABSTRACT
Free vascularized fibular flap is considered the treatment of choice in mandibular reconstruction for extensive bone defects (over 6 centimeters) resulting from trauma, infections or tumor resections. But, when the reconstruction involves a dentate mandible, the fibula has the limit as it does not offer sufficient bone height to restore the alveolararch up to the occlusal plane. Therefore, the deficiency in bone height makes implant placement impractical.We report a case of vertical distraction osteogenesis of a free vascularized fibula flap used to reconstruct a hemimandibleafter resection of an odontogenic myxoma, for optimization of the implant prosthetic rehabilitation. The distraction device was applied intraorally. After 10 days of latency period, distraction protocol was performed at adistraction rate of 0.5 mm per day. A consolidation period of 3 months followed. Afterwards the distraction device was removed and 3 osseo integrated dental implants were placed in the distracted area. As a result, the vertical discrepancy between the fibula and the native hemimandible was corrected. The amount of vertical height achievedafter distraction was 17 milimeters. The increase of vertical bone height was stable and enabled placement of dental implants without any complications. In conclusion, we consider that vertical distraction osteogenesis of free vascularized flaps is a reliable technique that optimizes implant positioning for ideal prosthetic rehabilitation,after mandibular reconstruction following tumor surgery (AU)
