Sinus augmentation is performed when the floor of the sinus is near to some area where dental implants are to be placed. Sinus elevation ensures a safe place for the implants while protecting the sinus. For dental implants, upper back jaw has been traditionally one of the most difficult areas due to insufficient bone quantity and quality.
Sinus lift surgery can help correct this problem by raising the sinus floor and upward bone for the positioning of dental implants.
What is the use of sinus lift surgery?
There are several reasons for the use of sinus lift:
- Many people who have lost teeth in their upper jaw, that includes back teeth and do not have enough bone for implants to be placed. The back of the upper jaw may have less bone that the lower jaw because of the anatomy of the dental area.
- Bone may have been lost because of periodontal disease.
- If teeth have been missing due to tooth loss for a long time, there often is not enough bone left to place implants.
- There might be loss of bone due to tooth loss. Once teeth are gone, bone begins to be reabsorbed. If teeth have been missing for a long time, there is not sufficient bone left to place implants.
The sinus lift is performed by an appropriately trained dentist or dental specialist who will follow the process that will cut the gum tissue where your back teeth used to be. This will expose the bone as the tissue will be raised. The membrane lining the sinus will be gently pushed up and away from your jaw.
It has become common during the last 15 years as many have started getting dental implants to replace missing teeth.
