Sinus augmentation, so called “sinus lift” is a surgery that adds bone to your upper jaw in the area of your back teeth. The bone is added between your remaining jawbone and the sinus membrane.
What it's used for
A sinus lift is done when there is not enough bone height in the upper jaw, for dental implants to be placed.
Sinus lifts have become common as more people get dental implants to replace missing teeth.
You will need X-rays taken before your sinus lift so the dentist can study the anatomy of your jaw and sinus. You also may need a special type of computed tomography (CT) scan. This scan will allow the dentist to accurately measure the height and width of your existing bone and to evaluate the health of your sinus.
