Bone and Sinus Augmentation

Lack of bone for dental implants

A key to dental 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 dental implants, and as such, may require either sinus lift surgery or bone augmentation.

Sinus Lift Surgery

A sinus lift prepares the area for the insertion of dental implants. This is positive news for patients who have previously been told they are not a good candidate for dental implants due to lack of bone height.

A sinus lift is a bone grafting procedure that can create the preferred five-millimetre bone needed to place a dental implant. This is achieved by moving the sinus membrane upward and fitting additional bone between the upper jaw and maxillary sinuses.

In addition, the sinus lift procedure provides more bone for patients whose teeth have been missing for long periods of time and the bone has resorbed as a result.

Vivek’s preferred choice of procedure is the crestal approach sinus lift, to minimise risk by providing a non-traumatic crestal approach to sinus elevation for patients, even if the sinus floor is flat, inclined or has a septum.

Patients planning to undergo the Sinus Lift procedure will undergo a clinical and radiographic assessment to thoroughly study their jaw and sinus anatomy. In addition, a cone-beam CT (CBCT) scan is needed. This allows the measurement of the current bone, as well as to assess of the overall health of the sinus.

Bone Augmentation

Candidates for bone augmentation, a process of rebuilding the bone, are patients with an insufficient natural, healthy bone to support dental implants.

The goal is to provide a solid structure where implants can be placed and secured in the alveolar bone structure. The augmentation is most commonly done by a bone graft, which is placing bone graft material to the existing bone in your jaw.

Patients planning to undergo bone augmentation procedures will undergo a clinical and radiographic assessment to thoroughly study their jaw and bone defect. In addition, a cone-beam CT (CBCT) scan is needed. This allows the measurement of the current bone and shape of the defect to plan what extent of graft is required.

Modern bone grafting is generally a painless, minimally invasive procedure completed in the practice. Once the procedure has been completed, the graft material is left for 3-6 months to heal before dental implants can be placed, depending on the extent of the graft and the condition of the existing bone.

Where does the bone come from for bone augmentation?

There are several options for bone grafting material:

All options will be fully discussed at the treatment planning stage with patients who may have specific requirements.
