Sinus elevation using a staged osteotome technique for site development prior to implant placement in sites with less...

Since the osteotome technique with simultaneous implant placement becomes less predictable when there is less than 5 mm of preexisting alveolar bone height beneath the sinus, a staged approach has been recommended for this situation. The purpose of the present article is to describe the osteotome technique as a site development method where the edentulous posterior maxilla radiographically showed less than 5 mm of bone between the alveolar crest and the sinus floor.
