Bone graft and sinus lift

Patients who lose some or all of their natural teeth may experience bone loss, or resorption, when the jaw bone in the area of the missing tooth shrinks back and dissolves.

A bone graft may be required to restore the bone in the affected are until it is of sufficient density to support dental implants.

What is a Bone Graft?

A bone graft procedure involves the use of your own bone tissue, donor bone from a bone bank or synthetic material to rebuild the bone in the jaw so that it can support a dental implant.

Bone generally has the ability to regenerate completely if provided the space into which to grow. As native bone grows, it will generally replace the graft material completely, resulting in a fully integrated region of new bone. Most bone grafts are expected to be reabsorbed and replaced as the natural bone heals over a few months.

ENDORET® Technology and the Bone Grafting Process

At Shields Dental, we use a revolutionary new technology called ENDORET (prgf) to help speed up the bone grafting and healing process.

ENDORET (prgf) is based on the extraction and use of the patient’s own proteins for the stimulation of bone healing and regeneration.

Endoret increases the blood supply to the bone graft and encourages the formation of new bone.

Also, when the surface of a dental implant is wetted with ENDORET liquid, a fibrin membrane is formed which adheres to the surface of the dental implant and releases growth factors which improves the process of osseointegration. Osseointegration is where the bone and dental implant become structurally connected.

When is a Sinus Lift Required?

Sinus LiftA sinus lift is done when there is not enough bone height in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed.

The procedure is one in which the sinus lining is lifted to make room for the growth of new bone (following a bone graft) so that the implants can then be placed.

There are several reasons why a patient may not have sufficient bone height in the upper jaw to support dental implants:

  • Tooth Loss – Some people who have lost upper molars (or premolars) do not have enough bone for implants to be placed. Once teeth are gone, bone begins to be resorbed (absorbed back into the body). If teeth have been missing for a long time, there often is not
