Augmentation of the posterior maxilla by way of sinus grafting procedures: recent research and clinical observations.
This article presents some of the clinical problems with bony augmentation of the posterior maxilla using sinus lift procedures to effect alveolar bone reconstruction. The antral membrane and the bone of the antral floor have regenerative potential commensurate with other bone of the maxilla and mandible. The stem cells involved in the periosteum of the sinus floor and the mucoperiosteum of the oral cavity covering the osteotomy opening combine to form a very receptive site for grafting and surgical procedures. Distraction osteogenesis, with and without bone inductor cytokines, will play a prominent part in sinus floor augmentation and in posterior maxillary alveolar bone grafting in the future.
