Bone grafting is often associated with dental restorations such as bridge work and dental implants. When the jawbone has receded or sustained significant damage, the implant(s) cannot be supported on this unstable foundation. Bone grafting can increase the probabilities for a successful restoration.
There are several major factors that affect jaw bone volume:
-
Periodontal Disease – Periodontal disease can affect and permanently damage the jaw bone that supports the teeth. Affected areas progressively worsen until the teeth become unstable.
-
Tooth Extraction – Studies have shown that patients who have experienced a tooth extraction subsequently lose 40-60% of the bone surrounding the extraction site during the following three years. Loss of bone results in what is called a “bone defect”. (This is another reason we recommend not waiting to replace lost teeth with a dental implant; even immediate placement).
-
Injuries and Infections – Dental injuries and other physical injuries resulting from a blow to the jaw can cause the bone to recede. Infections can also cause the jaw bone to recede in a similar way.
What Does Bone Grafting Do?
Jaw Stabilization – Bone grafting stabilizes and helps restore the jaw foundation for restorative or implant surgery. Deformities can also be corrected and the restructuring of the bone can provide added support.
Preservation – Bone grafting can be used to limit or prevent bone recession following a tooth extraction, periodontal disease, or other invasive processes.
What Does Bone Grafting Involve?
There are several types of bone grafts. Your doctor will determine the best type for your particular condition.
Autogenous Bone Graft - Harvested from the patient’s own body is the most invasive but can give predictable results.
Allograft Bone Graft - Cadaver or synthetic bone is used in this type of graft and is safe universal.
Xenograft - Cow bone is used in this type of graft.
Supplementing the jaw with bone will result in greater bone mass to support and anchor the implant(s).
