Bone Grafting

gumBone grafting is often closely associated with dental restorations such as bridge work and dental implants. In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the jawbone at the implant site. When the jawbone has receded or sustained significant damage, the implant(s) cannot be supported on this unstable foundation and bone grafting is usually recommended for the ensuing 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”.
  • 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.

Reasons for bone grafts

Bone-GraftingBone grafting is a highly successful procedure in most cases. It is also a preferable alternative to having missing teeth, diseased teeth, or tooth deformities. Bone grafting can increase the height or width of the jawbone and fill in voids and defects in the bone.

There are essentially two basic ways in which bone grafting can positively impact the health and stability of the teeth: jaw stabilization and preservation.

What Does Bone Grafting Involve?

There are several types of bone grafts. Your dentist will determine the best type for your particular condition.

Autogenous Bone Graft – Harvested from the patient’s own body (usually from the posterior part of the lower jaw or the chin). This method is usually preferred because it produces the most predictable results.

Allograft Bone Graft – Cadaver or synthetic bone is used in this type of graft.

Xenograft – Cow bone is used in this type of graft.
