A sinus lift surgery is a procedure that adds bone mass to your upper jaw, targeting the area of your molars and premolars. It’s also called a sinus augmentation. During the procedure, the bone is added between the jaw and a maxillary sinuses which are on either side of the nose. In order to make room for the bone, the sinus membrane needs to be lifted by a specialist: either an oral or maxillofacial surgeon in most cases.
These maxillary sinuses are empty spaces filled only with air. Some of the roots of your natural upper teeth extend into that space. Once the teeth are removed, all that’s left is a thin wall of bone separating the maxillary sinus and the mouth. Because dental implants require sufficient bone mass to hold them in place, it’s not possible to place dental implants into this bone.
Besides the natural thinness of the bone, there are other reasons why there may not be enough bone mass to place implants in that region:
- Bone mass may have been lost because of periodontal or gum disease
- Tooth loss can contribute to bone loss, as the bone begins to be absorbed back into the body once a tooth is lost.
- The maxillary sinus may be too close to the upper jaw to place implants. This varies from person to person, and the sinus can get larger as you age.
A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw region. The procedure grows the bone, strengthening it enough to place a dental implant.
Who Is a Candidate for the Sinus Lift Procedure?
Sinus lifts might be necessary if:
- You are missing more than one tooth in the area near the back of your jaw
- You are missing a significant amount of bone in the back of your jaw
- You are missing any teeth because of a birth defect or condition
- You are missing most of the maxillary teeth, but you need the support for dental implants
The Sinus Lift Procedure
The most common procedure involves making a small incision on the premolar or molar region to expose the jawbone. Using a small opening cut into the bone, the membrane lining the sinus is lifted upward and the exposed space is filled with bone grafting material. That can come from your own body, or from a cadaver. In some cases synthetic materials can be used. After the bone is implanted, the incision is stitched up and the body is left to heal itself. If enough bone in the region is available, the sinus lift and the implant placement can be done in a single procedure. Otherwise, they’ll have to be performed separately. Sinus lifts are usually performed at Dr. Shahriari’s office under local anesthesia.
Dr. Shahriari uses this cutting edge technology to elevate the sinus floor using neurosurgical drills. This technique is used to prevent the sinus floor from tearing which is very common. Dr. Shahriari teaches this technique to other doctors around the world.
