Augmentation of the atrophic maxilla with interpositional autogenous bone grafts

Extreme ridge atrophy is a significant problem when it occurs in the maxilla, since inadequate denture function, as well as poor facial aesthetics, commonly result. Use of the Le Fort I osteotomy of the maxilla with interpositional iliac cortico-cancellous bone grafts is a predictable method of ridge augmentation in severe cases. In our experience, secondary vestibuloplasty has not been necessary prior to construction of new prostheses. Patient satisfaction has been excellent.
