Bone Grafting

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.

Reasons for bone grafts

Bone 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 – 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.

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. Depending on these results, the dentist may also anesthetize the area and explore into the gum in order to determine what kind and how much bone is required.

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.

The bone grafting procedure can often take several months to complete. Bone is typically harvested from your own body (or on rare occasions obtained from a “bone bank”) and added to the affected site. This bone will fuse with the existing bone and the migration of cells will cause firm adhesion and cell growth. 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. On occasion, 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 does not require an overnight stay, and you will be provided with comprehensive instructions for your post-operative care. The dentist will prescribe medications to help manage infection, discomfort and swelling.

If you want to know what I think of Dr. Afzali and her staff all you really need to know is that I live in Portland and I fly to San Diego to see Dr. Afzali for all my dental work. That might seem a bit extreme, and perhaps it is, but hear me out before you decide. A couple of years ago when I was living in the Bay Area I had to have one of my front teeth removed and dental implant inserted in its place by a dentist in the Bay Area. The implant looked a little shorter and darker than my other teeth, and even made my gum above it look a bit darker than the adjacent gum. In short, it didn't look natural. So I wasn't completely satisfied with how my smile looked, but I thought that was the best that could be done. It wasn't.

Last summer while I was in San Diego visiting my parents I went to Dr. Afzali for a routine cleaning. She examined my mouth and immediately asked me whether I was happy with the way my implant looked. When I said I wasn't, she explained that she could make it look better and possibly even indistinguishable from my other teeth. She was right. My implant looks just like my other teeth, and my gum is pink again. In fact, my new implant looks so natural that I sometimes forget it's an implant. I couldn't be happier. One final point. Dr. Afazli's entire staff is great. When I walk in they all make me feel like I'm the most important patient they have. And Julie is particularly great. Because I live in Portland my visits to Dr. Afzali's office had to me perfectly timed with receipt of the various parts necessary for my procedures. Julie made sure that everything arrived when necessary, without fail, so that no flights or appointments had to be rescheduled.

Recently, while on a trip from Canada to visit friends in San Diego, I broke a tooth. I phoned RB Dentistry and was given an appointment without delay. Dr. Mary Afzali was reassuring and professional and did an excellent job fixing the broken tooth. Her dental assistant, Marinette, was kind and gentle and made me feel comfortable throughout the procedure. Julie at Reception was welcoming, warm and made me laugh with her wonderful sense of humour and handled the insurance processing with no complications. Thank you so much Dr. Afzali, Mari and Julie for one of the most pleasant dental appointments I've had in a long time! Hope to see you in Vancouver, B.C. sometime!

I know I am in good hands with Dr. Afzali at RB Family Dentistry. The cavity fillings and tooth root fillings I got there were done so well that when I went to the Southwest College Dental Hygenist school to help out a friend, they could barely even detect the fillings! The teachers there were very impressed. At RB Family Dentistry, the staff and hygenists are friendly, organized and very knowledgable, and the Dr. always gives me as much time as I need and answers all of my questions. The office is beautiful and state-of-the-art. They never try to sell me on additional products or services that I don't need.
