Sinus Lift

What is a Sinus Lift?

The maxillary sinuses are behind your cheeks and above the upper teeth. These sinuses are empty, air-filled spaces. The roots of upper posterior teeth extend up into the maxillary sinuses. When these upper teeth are removed there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.

The key to a successful and long-lasting dental implant is the quality and quantity of jaw bone to which the implant will be attached. Sinus augmentation or lift can raise the sinus floor and allow for new bone formation. A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw. The procedure seeks to grow bone in the floor of the maxillary sinus that anchors the teeth in the upper jaw. This enables dental implants to be placed and secured in the new bone.

Am I a Candidate for a Sinus Lift Procedure?

A sinus lift may be necessary if you:

  • are missing one or more teeth in the back of your upper jaw
  • are missing a significant amount of bone in the back of your upper jaw
  • are missing teeth due to a birth defect or condition
  • are missing most of the maxillary teeth and require support for dental implants

How is this procedure Accomplished?

Commonly, an incision is made on the premolar or molar region to expose the jaw bone. A small opening is prepared into the sinus wall, and the membrane lining the sinus is pushed upward. The underlying space is filled with the bone graft. After the bone is implanted, the incision is sutured and the healing process begins. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in the newly formed sinus bone.

If enough bone between the upper jaw ridge and the bottom of the sinus is available to sufficiently stabilize the implant, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the graft will have to mature for several months. Once the graft has matured, the implants can be placed.

The sinus graft makes it possible for many patients to have dental implants that previously had no other option besides wearing loose dentures.
