What is it?
A sinus lift is a type of surgery that adds bone to your upper jaw in the area of your molars and premolars. It's sometimes called a sinus augmentation. The bone is added between your jaw and the maxillary sinuses, which are on both sides of your nose. To make room for the bone, the sinus membrane has to be lifted. Most of the time a sinus lift is done by an oral or maxillofacial surgeon.
What's it used for?
A sinus lift is preformed when there is not enough bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed. There are several reasons for this:
-When people lose their teeth in their upper jaw, it is normally in their back teeth or molars. And due to the anatomy of the skull, the back of the upper jaw has less bone than the lower jaw.
-The bone may have been lost because of gum disease
-Tooth loss could have led to bone loss as well. Once your teeth are gone, your bone starts to be absorbed back into the body.
-The maxillary sinus may be too close to the upper jaw for implants to be placed. The shape and size of your sinus varies from person to person.
You must have X-rays taken before your sinus lift so the dentist can study the shape of your jaw and sinus. You also may need a Tomography scan before as well so that the surgeon can measure the height and width of your existing bone.
Note: If you have seasonal allergies, you should schedule the procedure when they are not active
How its done.
1.The surgeon will cut the tissue where your back teeth used to be. The tissue will be raised exposing the bone. Then, a small cut is made into the bone. After the cut is made, the membrane that lines your sinus is gently pushed up away from the jaw.
2. Granules of bone material are packing into the space where the sinus was. Several millimeters of bone material are added above the jaw.
3. Once the bone is placed, the tissue is closed with stitches. Your implants will be placed four to nine months later allowing time for the grafted material to mesh with the bone.
You may have swelling and bleeding in your nose and mouth after the procedure. Make sure that you do not blow your nose to forcefully because you could cause the new bone to move or the stitches to loosen. Your dentist may give you saline sprays to keep the inner lining of your nose went to prevent inflammation. You will also be given a pain medicine. After 7 to 10 days, you will need to see the specialist to get your stitches removed.
