A key to implant success is the quantity and quality of the bone where the implant is to be placed. The upper back jaw has traditionally been one of the most difficult areas to successfully place dental implants due to insufficient bone quantity and quality and the close proximity to the sinus. If you've lost bone in that area due to periodontal disease or tooth loss, you may be left without enough bone to place implants.
Sinus lift surgery can help correct this problem by raising the sinus floor and developing bone for the placement of dental implants. Several techniques can be used to raise the sinus and allow for new bone to form. In one common technique, an incision is made to expose the bone. Then a small rectangular opening through the thin outside wall of the jaw is made. This bony piece is lifted into the sinus cavity, much like a trap door, and the space underneath is filled with bone graft material which will encourage the growth of new bone tissue.
