Implant reconstruction of the severely resorbed edentulous maxilla frequently requires autogenous block bone graft reconstruction. This can be accomplished with iliac, cranial or mandibular corticocancellous block bone grafts. Depending on the degree of bone loss, the patient’s functional or aesthetic requirements, and the prosthodon- tic requirements, the bone graft procedures can either be a one- or two-stage reconstruction. The one-stage reconstruction requires simultaneous placement of block bone grafts and endosseous root form dental implants. In the two-stage procedure, bone grafting and implant placement procedures are separated by 3–6 months to allow for bone graft healing. The bone grafting procedures are classified anatomically as onlay, inlay or interpositional types.
