Bone Grafting & Periodontal Regeneration
Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants.
Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and aesthetic appearance.
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided tissue regeneration.
Guided Bone and Tissue Regeneration
Gum disease has traditionally been treated by eliminating the gum pockets by trimming away the infected gum tissue and by re-contouring the uneven bone tissue. Although this is still an effective way of treating gum disease, new and more sophisticated procedures are used routinely today. One of these advancements is guided bone regeneration, also referred to as guided tissue regeneration. This procedure is used to stabilize endangered teeth or to prepare the jaw for dental implants.
As periodontal disease progresses, pockets of degenerated bone develop in the jaw. These pockets can promote the growth of bacteria and the spread of infection. To address these pockets, Dr. Russo or Dr. Braga may recommend tissue regeneration. During this surgical procedure, the pockets are cleaned thoroughly, and a membrane is installed between the soft tissue and the pocket in the bone. Some of these membranes are bio-absorbable and some require removal. The membrane covers the pocket so that fast-growing soft tissue is blocked, and slower-growing bone can begin to grow, or “regenerate” itself.
The effectiveness of the procedure generally depends on the patient’s willingness to follow a strict postoperative diet and careful oral care. Dr. Russo and Dr. Braga will help you determine if bone regeneration surgery is right for you.
