Abstract
Insufficient bone volume is a common problem encountered in the rehabilitation of
the edentulous posterior maxillae with implant-supported prostheses. Bone volume is
limited by the presence of the maxillary sinus together with loss of alveolar bone
height. Sinus lift procedures increase bone volume by augmenting the sinus cavity
with autogenous bone or commercially available biomaterials, or both. This is an update
of a Cochrane review first published in 2010.
