Autogenous rib graft-hydroxylapatite augmentation of the severely atrophic mandible: preliminary report.

Traditional transoral rib grafts were combined with particulate hydroxylapatite (HA) for augmentation in four patients who had advanced alveolar atrophy or cortical resection of the mandible. Follow-up evaluation for up to 18 months revealed restoration of mandibular morphology, with good prosthetic function and insignificant resorption. No infection or graft loss was observed, in spite of wound dehiscence in two of the four patients, possibly due to the placement of the HA lateral and superior to the rib grafts.
