Sinus Lift

The sinuses are large, empty air spaces which lie underneath your cheekbones. The size of these air spaces vary from person to person, and the roots of the upper back teeth can lie in close relation to the sinuses, especially if the sinuses are large. When upper back teeth are extracted, the sinus generally tends to enlarge downwards, which can mean that following Extractions you may end up with insufficient bone to place a implant. If that is the case, the lost bone can be replaced by means of a bone grafting procedure called a ‘sinus lift’.

The procedure involves placing an artificial bone material in the very lowest part of the sinus. This artificial bone material is then left to mature and solidify over 6 months before it is ready to receive a dental implant.

The pictures below are X-rays of actual cases carried out at here 3 Dental:

This is an X-ray showing missing teeth on the upper right side. The sinus is outlined and as we can see there is very little bone available below the sinus. This means that there is insufficient bone to place a dental implant.
The outline shows the aftermath of a sinus life. Bone graft material has been placed, meaning there is now sufficient bone available to place dental implants. Also note that the lower tooth has been removed as it was decayed and the patient was treated for gum disease.

How is a Sinus Lift Performed?

Once the dentist has examined the X-rays which highlight the anatomy of your jaw and sinus, only then can a sinus lift begin.

    1. Gum tissue where your back teeth used to be is cut and raised to expose the bone
    2. A small, oval window is opened in the bone
    3. The membrane which separates your sinus from your jaw is pushed up and away from your jaw
    4. Bone graft materiel is placed into the section where your sinus used to be
    5. After the materiel has been put in place, stitches are used to close the tissue
    6. Time is allowed for the graft to mature after which your implants will be placed
