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 circle is cut into the bone. This bony piece is lifted into the sinus cavity, much like a trap door, and the space underneath is filled with bone graft material.
Finally, the incision is closed and healing is allowed to take place. Another technique is called an internal sinus lift. This involves obtaining access to the sinus cavity through an osteotomy, or a vertical internal opening created in the bone. Bone is added to the floor of the sinus to increase the bone height in order to support a dental implant.
Depending on your individual needs, the bone usually will be allowed to develop for about 4 to 6 months before implants can be placed. After the implants are placed, an additional healing period is required. In some cases, the implant can be placed at the same time the sinus is augmented.
Undergoing sinus lift surgery has been shown to greatly increase your chances for successful implants that can last for years to come. Many patients experience minimal discomfort during this procedure.
