Sinus augmentation is performed when there is not enough bone in the upper jaw or the sinuses are too close to the jaw for dental implants to be placed. During this procedure, your doctor will add bone between your jaw and sinus, in addition to lifting the sinus membrane to make room for the extra bone.
Periodontal disease can cause bone loss, and because of the anatomy of the skull, the back of the upper jaw naturally has less bone than the lower jaw. If your periodontal disease has left you with too little bone in your upper jaw, sinus augmentation can allow your periodontist to create a healthy foundation for an implant to be placed.
The Procedure
Your doctor will cut into the gum tissue and lift it away from the bone. A small area of bone will be removed, allowing your periodontist to gently push the sinus membrane up and away from the jaw. Then, a bone graft will be placed into the space where the sinus membrane was. Once in place, the gum tissue is stitched closed and the bone graft material will begin to grow, filling in the areas of lost bone. When the grafted material is fully meshed with the existing bone, your periodontist will be able to place your implant, returning your mouth to an ideal state of function and aesthetics.
Sinus Precautions
Your doctor may recommend additional precautions for the sinus area. Following the removal of upper teeth or surgery of the upper jaw, there is a possibility that an opening or communication between the sinus and mouth may occur. The following instructions are precautions to prevent this from occurring or to allow this area to heal.
- Do not spit for five to seven days
- Do not smoke or use tobacco products for two weeks
- Do not use a straw for several days
- Do not forcefully blow your nose for two weeks, even though your sinus may feel "stuffy" or there may be some nasal drainage
- Avoid sneezing if possible, as this can cause increased pressure within the sinus. If you must sneeze, do so with your mouth open.
- Eat only soft foods for one week. Try to chew on the opposite side of your mouth.
- Do not rinse vigorously for one week. Gentle saltwater swishes may be used.
Slight bleeding from the nose may be seen up to 10 days after surgery. It is important to keep your office advised of any changes in your condition, especially if drainage or pain increases.
