Bone Grafts

Bone grafts are used to rebuild the jaw bone in cases of resorption (bone loss). They are a common procedure before, or during, having dental implants when there is not enough bone density to support the implants.

There are many causes of bone loss in the jaw. If you have a missing tooth or teeth for a significant amount of time, the jaw bone in the affected area starts to dissolve and shrink back. This can also be a side effect of severe, untreated periodontitis (advanced gum disease). In addition, if you have worn dentures for a long period of time, you may not have enough bone to support implants because dentures do not prevent resorption the same way implants do. Some bone loss is also a natural part of the ageing process.

If you choose to have dental implants at Castle Hill, we will take x-rays to establish whether you have enough bone to successfully hold the implants. Should we find resorption has taken place, you may need a bone graft.

At Castle Hill we use an advanced system to aid healing, which uses your own blood to increase the healing of the bone graft. We have embraced biotechnology and are leading the area in regenerative medicine. By using your own blood, we can stimulate healing of any wounds that might be made. An example would be after a tooth extraction as a healing plug.

While you are under sedation, we take a small amount of blood from you. This is put through a centrifugation and fractioning process, which produces plasma rich in growth factors. This patented process is known as PRGF and is FDA and CE approved. The plasma can be applied to the extraction socket, reducing pain and swelling and providing antibacterial protection from infection.

A further procedure, known as a sinus lift or sinus augmentation, is used for implants of upper back teeth, where the jaw bone is often shallow. The lining of the sinus is lifted up and implants are placed, before bone and osseo-conductive material is packed around the implants.

After a bone graft, you will require a healing period of months before final implants can be placed. Should you need a bone graft, you will have approximate timings included in your treatment plan.
