Successful mandibular reconstruction using a BMP bioimplant.

A bone morphogenetic protein bioimplant was used for primary reconstruction of a 6-cm mandibular discontinuity defect, after a segmental resection of an ameloblastoma. Radiographic evidence of new bone induction was seen at 3 and 9 months, postoperatively. A biopsy was taken at 9 months demonstrated viable new bone formation at the bioimplant site. This is the first reported case using a bone morphogenetic protein bioimplant in a human, followed by histological confirmation of new bone.
