With the introduction of osseointegration by Dr P.-I. Brånemark, reconstruction of advanced residual ridge resorption has become a successful procedure in patients for whom previous methods had been disappointing. For reconstruction of the maxillae an onlay, nasal and/or antral inlay, labial and/or buccal onlay, or interpositional bone graft with osseointegrated implants used to provide support for both the graft and the prosthesis can be used. The maxillary and mandibular onlay bone grafts and the nasal and/or antral inlay bone grafts are discussed.
