A sinus lift is a dental surgery that adds bone to your upper jaw in the area of your molars and premolars. It is sometimes called a sinus augmentation.
American Dental Association
However, before planning oral surgery it is necessary to determine if it is appropriate for the patient to undergo it.
This procedure increases vertically the amount of bone available in the areas where the patient has experienced a drastic bone loss that prevents the correct clamping of the implants.
The bone is added between your jaw and the maxillary sinuses, which are on either side of your nose. To make room for the bone, the sinus membrane has to be moved upward, or “lifted.”
Many people with missing upper teeth have suffered premature tooth loss or periodontal (gum) disease often related to poor dental care or simply genetics, causing bone loss. The maxillary sinus may therefore be too close to the upper jaw for implants to be placed
Generally, the materials used to add bone volume to the sinus floor are autogenous, biomaterials or both. The technique makes it possible to replenish dental parts in people who would not otherwise be able to have implant surgery.
It also strengthens the effectiveness of implant treatments and permanent dentures in the posterior area of the upper jaw, which is the area in which most failures are concentrated.
