sinus lift

Sinus lift (or sinus augmentation), is a dentist-executed procedure that adds bone to the upper jaw bone in the molar to premolar area, in order to render it thicker (jaw bone augmentation). The bone is often added between the jaw and the sinus cavities at either side of the nose. In order to make room for the bone, the sinus membrane is lifted.

Do I need a sinus lift?

This intervention is required when there is not sufficient bone in the jaw or the sinuses are too close to insert an implant. The reasons for this condition are many:

  • many people have lost their jaw teeth, above all the rear teeth (molars or premolars), they would like to insert one or more implants, but there is insufficient bone quantity;
  • due to cranium anatomy, the rear part of the jaw has less bone than the mandible;
  • the bone has been lost due to gum disease; once tooth loss has occurred, bone re-absorption begins and if the teeth have been missing for a long period of time, the bone left in is often slight;
  • the sinus cavity can be too close to the jaw in order to allow an implant insertion; it must be observed that sinus cavity size varies among individuals, and that it tends to increase in size with age.

Is this a safe procedure?

The sinus lift is a tested intervention that has been applied over the last 15 years and it accompanies the broad success of dental implant treatment. Naturally, only careful planning carried out by a dentist can avoid complications or risks.

What are the preparations?

The bone used in a sinus lift may come from your own body (autogenous bone), it can be bovine in origin (xenograft, most popular) or from a cadaver (allograft bone from a bone bank, common in USA).

If your own bone will be used in the sinus lift, it will be taken from other areas of your mouth or body. In some cases, the surgeon removes bone from your hip or tibia (the bone beneath the knee).
You will need dental X-rays and a computerised tomography (CT) scan before your sinus lift so the dentist can study the anatomy of your jaw and sinuses. This scan will allow the dentist to accurately measure the height and width of your existing bone and to evaluate the health of your sinus.

How is it done?

Your surgeon will cut the gum tissue where your back teeth used to be. The tissue is raised, exposing the bone. A small, oval window is opened in the bone. The membrane lining the sinus on the other side of the window separates your sinus from your jaw. This membrane is gently pushed up and away from your jaw.

Granules of bone-graft material are then packed into the space where the sinus was. The amount of bone used will vary, but usually several millimetres of bone is added above the jaw.

Once the bone is in place, the tissue is stitched closed. Your implants will be placed four to nine months later (or at the same time if possible). This allows time for the grafted material to mesh with your bone. The amount of time depends on the graft material that was used.

Is there any follow-up?

Following the dental surgery, patients commonly experience swelling in the sinus area, as well as some temporary bleeding in the mouth/nose. However, they are urged not to blow their nose or sneeze forcefully to ensure the stitches are not loosened and the bone graft material stays in place.

Individuals with seasonal allergies are advised to plan the procedure for an appropriate time of year for optimum results. To ensure limited recovery time is required, nasal sprays will be provided to keep the inside of the nose moist, along with medication to limit the risk of sneezing.

Your oral surgeon will request a follow-up appointment after two weeks to remove stitches and assess the healing progress of the affected area. Patients will be then asked to return on a regular basis in order to monitor their progress.
