Sinus Grafting

The maxillary sinuses are on top of the upper back teeth. Sinuses are like empty spaces lined with mucosa that serve as a part of your respiratory system.
Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone left separating the maxillary sinus and the mouth. 

Sinus Grafting

Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.

There is a solution and it is called a sinus bone graft or sinus lift. In this common procedure we enter the sinus from mouth, where the upper teeth used to be. The sinus membrane is then gently lifted upward and either patient’s or synthetic bone is inserted into the sinus.

In many cases, the implants are placed at the same time.

After several months of healing, the grafted bone becomes part of the patient’s jaw and teeth can be placed on the implants

Sinus Grafting

This common procedure and relatively painless procedure is only used to replace upper back teeth.

The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures.

In some cases, when the bone loss after extraction of upper back tooth area is minimal, it is possible to lift the sinus bone without opening a window in the sinus wall.

In this minimally invasive procedure, the sinus bone is actually moved up through the implant site at the same time the implant is placed. Bone replacement materials, if even necessary, can be added through the tiny implant socket.
