Augmentation of the Posterior Maxilla: A Proposed Hierarchy of Treatment Selection

Literature is reviewed that discusses treatment results following Cauldwel Luc approach sinus augmentation therapy or osteotome sinus augmentation therapy, with and without simultaneous implant placement. A hierarchy of treatment selection for the augmentation of the posterior maxilla, based upon quantity and position of residual alveolar bone crestal to the floor of the sinus, is proposed.
