Abstract

Bony defects in the alveolar bone, maxilla, paranasal region, and the floor of the nose were corrected in 75 consecutive patients with a composite bone graft. The composite bone graft is a mixture of a slurry of corticocancellous cranial bone, hydroxyapatite (R), and Bacitracin powder, and thrombin. The paste-like composite is used to pack the defect and correct the deformity. Complete bony immobilization, done externally or internally, is necessary during the healing phase of the bone composite. The patients were longitudinally evaluated, and the healing of the bone was assessed radiographically and clinically. Two major complications occurred during the healing phase at the recipient sites: one may have been indirectly related to the donor site, and the second was related to the age of the patient and the previous surgeries contributed to the partial loss. Composite bone grafts produce better results due to faster solidification of the grafts which acts acts as a strong inductive matrix. The graft is used in the alveolar ridge and in hard tissue augmentation of the bony structures in the maxilla. The prospectus for the future is to see more composites grafting, since it combines the advantages of the materials used.
