Bone-added osteotome sinus floor elevation for the deficient maxillary posterior implant site: case series

Implant placement in the posterior maxillary region is often compromised due to anatomic limitations. Often, factors like inadequate vertical dimension, poor bone quality, and undercuts result in placement of shorter and/or angled implants. The bone-added osteotome sinus floor elevation technique can be employed in many clinical situations that involve minimal bone height, resulting in increased bone height and placement of longer implants. This article will briefly review the literature and provide a detailed description of the technique as well as present multiple cases in which this procedure was used.
