If bone in the upper jaw is lost because of loss of tooth, injury or periodontal disease, a sinus augmentation can raise the sinus floor to match new bone formation.
In the most common sinus grafts or lift augmentation techniques, a tiny incision is created near the upper premolar or molar region to expose the jawbone. A small opening is cut in to the bone, and the membrane lining the sinus on the other side of the opening is gently pushed upward. The actual space is stuffed with bone graft material and also the incision is closed. The bone that is used in this procedure might be from your own body or another donor source. Sometimes man-made materials which can also stimulate bone formation are utilized. Dental implants are then placed after healing has occurred; it all depends around the individual case. Sinus augmentation has been shown to increase the success of dental implant procedures.
