A sinus graft life is surgery that adds bone to your upper jaw in the area of your back molars and pre-molars.
The bone is added between your jaw and sinuses, which are located on either side of your nose. To make room for the bone, the sinus membrane is moved upward, or ‘lifted’.
A sinus lift is done when there is not enough bone height in the upper jaw – which has less bone than the lower jaw – or the sinuses are too close to the jaw for dental implants to be placed.
An incision is made in the gum tissue and raised, exposing the bone. A small, oval window is opened in the bone. The membrane lining the sinus on the other side of the window separates your sinus from your jaw. This membrane is gently pushed up and away from your jaw.
Bone-graft material is then placed into the space where the sinus was located. The amount of bone used will vary, but usually several millimetres of bone is added above the jaw.
Once the bone is in place, the area is stitched together. Your implants will be placed four to nine months later. This allows time for the graft to integrate with your bone.
