Sinus Augmentation

The maxillary sinuses are air-filled cavities in your upper jaw. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. Once posterior upper teeth have been removed, there sometimes is not enough bone between your upper jaw and sinus. There is a solution and it’s called a sinus graft or sinus lift graft. The dental implant surgeon enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus.

The sinus bone graft makes it possible for many patients to have dental implants.

If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the dental implant well, sinus augmentations and dental implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the sinus graft will have to mature for several months. Once the sinus graft has matured, the dental implants can be placed into the healed bone.
