Bone Graft in San Diego

Bone 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.

Reason for bone grafts

Bone grafting is a highly successful procedure. Bone grafting can increase the height or width of the jawbone and fill in voids and defects in the bone. Bone grafting can be used to limit or prevent bone recession following a tooth extraction.  This helps prevent further bone loss, thus preserving the space for the placement of a future implant.  

Oral Examination

Initially, the dentist will thoroughly examine the affected area in order to assess the general condition of the teeth and gums. If periodontal disease is present or the adjacent teeth are in poor condition, these factors will be fully addressed before the bone grafting procedure can begin. The dentist will also recommend panoramic x-rays in order to assess the precise depth and width of the existing bone. On occasion, a CAT scan may be recommended to determine the bone condition. 

What Does Bone Grafting Involve?

Allograft bone, which is bone derived from human cadavers, is added to the affected site. This bone will serve as a scaffolding and a guide for your own cells to migrate into the desired area and form bone.   Supplementing the jaw with bone will result in greater bone mass to help support and anchor the implant(s).

During the surgery, the dentist will numb the grafting and extraction sites using local anesthetic. A small incision will be made to prepare the site for the new bone and it will be anchored into place. 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 dentist will prescribe medications to help manage infection, discomfort and swelling.
