Sinus Lifts

A sinus lift (also called sinus augmentation) is a surgical bone grafting procedure that aims to increase the level of bone prior to implant placement in some patients. Sinus lifts are done in the areas of the upper pre-molar or molar teeth.


 When an implant needs to be places for a patient who lacks sufficient bone height in the area beneath their sinus, a sinus lift is necessary. The bone in this area may be insufficient due to the patient’s anatomical peculiarities, because a tooth in that area has been missing for a long time, or due to underlying periodontal disease.


 A sinus lift is typically completed in a single surgery.

  • The area is numbed using local anesthesia.
  • A small incision is made to expose the maxilla (upper jaw bone) and the membrane of the sinus is lifted.
  • Bone grafting material is added into the space created by the movement of the sinus membrane.
  • The area is covered with a protective membrane.
  • The gums are sutured.
  • The bone grafting material mineralizes completely over the course of 4-6 months, before an implant can be successfully placed into the area.


 You will be given detailed post-operative instructions specific to your individual case.

Sinus grafting is typically the initial stage of implant-based restorations. It is important to keep the area clean, to ensure proper healing and reduce the chance of infection.


Acute sinusitis, loss of the bone grafting material, hemorrhage, or infection can occur especially in the chance that post-operative instructions are not properly followed.

We encourage patients to contact the office immediately if they have any questions or anything doesn’t feel normal.


 Insurance coverage for sinus lifts is extremely limited due to plan exclusions, usually in the 50-80% range where available. The best way to determine coverage is by submitting a preauthorization request. The office of Dr. Mazen Natour will handle all insurance matters for its patients. Please call us if you have any questions about your coverage.
