Maxillary Sinus Floor Elevation: Review of Anatomy and Two Techniques

Abstract

A review of maxillary sinus floor elevation as an integral part of restoring the posterior maxilla is discussed. The related anatomy of the area and the current techniques available are reviewed. The classic lateral antrostomy pioneered by Tatum appears to be the most common sinus lift procedure. The more conservative crestal approach, advocated by Summers, provides another effective way of allowing implant fixture placement in the atrophic maxilla.
