Bone Grafting

Bone grafting is often closely associated with dental restorations such as fixed bridge work, dental implants as well as compete and partial dentures. In the majority of cases, the success of a restoration procedure can hinge on the height, depth, and width of the bone at the implant site. When the bone has receded or collapsed, the implant(s) cannot be supported on this unstable foundation and bone grafting is needed for proper restoration of the site.

There are several major factors that affect jaw bone volume:

• Periodontal Disease – Periodontal disease can affect and permanently damage the 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 will compromise any future restorative options.
• Injuries and Infections – Dental injuries and infections can cause the bone to recede and collapse.

Reasons for bone grafts

Bone grafting is a highly successful procedure . 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 bone and fill in voids and defects in the bone allowing for the proper restoration of the extraction site.

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

Bone Stabilization – Bone grafting stabilizes and helps restore the boney 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 loss following a tooth extraction or from periodontal bone/gum disease.

Oral Examination

Initially, Dr. Gray will thoroughly examine the affected area in order to assess the general condition of the teeth and gums. If periodontal bone/gum disease is present or the adjacent teeth are in poor condition, these factors will be fully addressed before the bone grafting procedure can begin. Dr. Gray may also recommend a CBCT scan in order to assess the precise depth and width of the existing bone. Depending on these results, Dr. Gray may also anesthetize the area and gently probe in order to determine what kind and how much is present.

What Does Bone Grafting Involve?

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

Allograft Bone Graft - Bone from a bone bank (similar to a blood bank for transfusions) or synthetic bone is used in this type of graft.

Xenograft  (non human sources)- Bovine or porcine collegen is used in this type of graft.

During the surgery, Dr. Gray will numb the grafting and extraction sites using local anesthetic.  A synthetic membrane may be used to cover the new bone. This membrane prevents soft tissue and bacterial invasions, and encourages new bone growth. The surgery is performed in the office, and you will be provided with comprehensive instructions for your post-operative care. Our office will prescribe medications to help manage infection, discomfort and swelling.
