Bone Augmentation


If you have a missing tooth or teeth the underlying bone may shrink in all directions leaving insufficient bone to place a dental implant. If teeth have been missing for a long time and you have been wearing removable dentures, often bone resorption may be significant. This can also be the case with advanced periodontal disease (gum disease), fractured teeth, infected teeth or trauma.

Thankfully at dentists in Perth we have the experience to provide a treatment protocol which allows us to augment (graft) deficient bone so that dental implants can be placed. A thorough clinical and radiographic assessment is important to allow us to determine the size of the augmentation required. Dental implant placement require that the bone is as close to its original position and size for optimal support of the skin, muscle and cosmetic appearance of the final crown, bridge or denture supported by the implants.

Different types of bone grafts with different properties are available and evolving rapidly with constant research.

  1. Autograft bone: bone which is obtained from the same individual receiving the graft
  2. Allograft: bone derived from humans other than the one receiving the graft.
  3. Alloplastic: a mineral component of bone known as hydroxyapetite may be used. It is a synthetic substitute used as a scaffold to allow the bone cells to build new bone onto.
  4. Xenograft: bone derived from a species other than humans such as bovine.
  5. Ceramic based grafts: these are the most common which consists of biocompatible, bioactive and resorbable materials such as calcium sulphate, calcium phosphates, bioactive glass. They facilitate bone formation at the site they are placed.

There are many other technological advances and research is ongoing. Newer forms of bone grafting involve the use of growth factors and stem cell technology.

You can be sure at dentists in Perth the right solution will be provided for you.
