SINUS LIFT SURGERY
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 reasons such as 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 membrane of the sinus floor and developing bone for the placement of dental implants. Several techniques can be used to raise the sinus membrane 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. Your periodontist can explain your options for graft materials, which can regenerate lost bone and tissue.
Finally, the incision is closed, and healing is allowed to take place. Depending on your individual needs, the bone usually will be allowed to develop for about four to twelve 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.
In the most common sinus augmentation technique, a tiny incision is made near the upper premolar or molar region to expose the jawbone. A small opening is cut into the bone and the membrane lining the sinus on the other side of the opening is gently pushed upward. The underlying space is filled with bone graft material and the incision is closed. The bone which is used for this procedure may be from your own body or from a cadaver. Sometimes the dentist might use synthetic materials which can also stimulate bone formation. The implants are placed after healing has occurred; this will depend on the individual case. Sinus augmentation has been shown to increase the success of dental implant procedures.
