You can find the maxillary sinuses behind your cheeks and above your upper teeth. Sinuses are like vacant, empty rooms. Some roots of the natural upper teeth extend up into the maxillary sinuses. When these teeth are removed, just a thin wall of bone separates the maxillary sinus and the mouth. To be held in place, dental implants need to attach to bone. If the sinus wall is too thin, dental implants cannot attach to the bone.
Sinus grafts or sinus lift grafts can work around this problem. With this solution, the dental implant surgeon enters the sinus from where the upper teeth used to be. Then, the sinus membrane is lifted upward and the surgeon inserts donor bone into the floor of the sinus (the roof of the upper jaw). The bone will become a part of the patient’s jaw after several months of healing, and dental implants can be inserted and stabilized into the new sinus bone.
Sinus grafts are a great new technology that makes it possible for many patients, who previously may have had to resort to loose dentures, to have dental implants.
If there exists enough bone between the upper jaw ridge and the bottom of the sinus to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If there isn't enough bone available, we'll perform the Sinus Augmentation first and allow the graft to mature for several months, depending upon the type of graft material used. Once the graft has matured, we can place your implants!
