Combinations of Grafts

The ideal graft would have the structural characteristics of a block graft with the qsteogenic potential of particulate  marrow and cancellous-bone grafts. However, a large block graft necessitates removal of a large portion of the patient’s anatomy and does ‘not provide the high concentration of osteogenic cells the particulate marrow and  cancellous-bone graft does. A technique that is commonly used to reconstruct defects of the mandible uses the advantages of both autogenous and allogeneic bone grafts (Fig. 28-2). An allogeneic block graft is obtained in the form of an ilium or mandible. This graft is used for its structural strength and protein, which induces phase II
bone formation from the surrounding tissues. This .graft is hollowed out until only the cortical plates remain. Autogenous particulate marrow and cancellous bone is then obtained and packed into the shell to provide the
