Sinus Lift Augmentation
After the loss of upper back teeth, your sinuses may enlarge. Before new implants replace the lost teeth, a sinus lift augmentation or graft relocates the sinus cavity into its original position and replaces the bone that has been lost.
Sinus augmentation is performed when there is not enough bone in the upper jaw, or the sinuses are too close to the jaw for dental implants to be placed. During this procedure, bone is added to gain height between your jaw and sinus, as well as lifting the sinus membrane to make room for the extra bone.
Periodontal disease can cause bone loss, and because of the anatomy of the skull, the back of the upper jaw naturally has less bone than the lower jaw. If your periodontal disease has left you with too little bone in your upper jaw, sinus augmentation will create a healthy foundation for an implant to be placed.
