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 report
ed case using a bone morphogenetic protein bioimplant in a human, followed
by histological confirmation of new bone.
