What is maxillary sinus operation?

With age, following old tooth extractions, or following a maxillary cyst, an abscess, osteitis or because of all kinds of periodontal problems, the jawbone can be reduced. However, to be able to place dental implants with sufficient bone thickness and height, otherwise implant placement is impossible. It is in this kind of complication that the operation of the maxillary sinus occurs.

 
 

Maxillary sinus surgery is a form of bone dental surgery that adds bone or bones to your jawbone in the area of the molars and premolars. This operation, which is also very often called sinus augmentation, is also a kind of bone graft in the sense that an artificial bone or directly from a part of the human body is grafted into the area between the jaw and the legs. maxillary sinuses located on either side of the nose. Thus, for this elevation to occur, specialists in oral and maxillofacial surgery are needed. Indeed, this sinus lift operation makes it possible to cope with a bone deficit in the upper jaw, when the sinuses are close enough or even too much to the jaw or simply when you want to perform a dental implant.

In the majority of cases, the bone used for this sinus lift is artificial bone that will go directly to your jawbone. However, in some very rare and extreme cases, it can happen that the bone comes from part of your body or from other parts of the mouth. You will first need to have x-rays so that the specialist has a clear view of the morphology of the jaw, but also with the help of a CT scanner, the dentist will be able to measure the dimensions of your bone and assess the health of the sinus.

Although the amount of bone used varies, usually only a few millimeters of bone are placed. Once this operation is complete, it will take 4 to 9 months for the implants to be placed.

Sinus lift by bone grafting remains an opportunity for people who have lost molars and premolars or people with an anatomical structure that does not facilitate dental implants.

DURATION OF TREATMENT: This procedure can last between 1 to 3 hours, depending on your condition.
