A sinus lift is a dental surgery that adds bone to your upper jaw in the area of your molars and premolars. It’s sometimes called a sinus augmentation.
This procedure increases vertically the amount of bone available in the areas where the patient has experienced a drastic bone loss that prevents the correct clamping of the implants.
The bone is added between your jaw and the maxillary sinuses, which are on either side of your nose. To make room for the bone, the sinus membrane has to be moved upward, or “lifted.”
It also strengthens the effectiveness of implant treatments and permanent dentures in the posterior area of the upper jaw, which is the area in which most failures are concentrated.
