The roots of the maxillary (upper) molar teeth are embedded in sinuses. When maxillary molar teeth are missing the sinuses tend to collapse. Unfortunately, when these same individuals decide to replace the missing teeth with dental implants there may be inadequate bone remaining to support them. This is when a sinus lift or elevation is indicated. A sinus lift or elevation is a surgical procedure used to lift the sinus membrane upward to its previous position. Donor bone is then inserted into the floor of the sinus to keep it in its place. After several months of healing, the bone becomes part of the patient's jaw and dental implants can be inserted and stabilized in this new sinus bone.

The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures.

It is often possible for sinus elevations and installation of implant fixtures to be accomplished in a single surgical episode if enough bone is still remaining.
