The maxillary posterior edentulous region presents a challenge when planning for restoring missing teeth with a dental implant. The available bone in such cases is often not dense and not adequate for the placement of a properly sized implant because of maxillary sinus pneumatization and alveolar bone loss. Maxillary sinus lift is a predictable procedure to provide adequate bone height for the ...

Introduction Because of ageing and loss of teeth, alveolar bone volume has a tendency to decrease, contrary to basal bone volume which seems to have no significant modification. The practician will have, if possible, to intervene before bone anomaly installation by intercepting bone resorption. (1) Bone volume diminution in posterior maxillary alveolar ridge is a combination of several simultan...
