Bone Grafting

Bone grafting is often associated with dental restorations like bridges and implants. The success of these procedures depends on the quality and volume of the jawbone at the implant site. When the jawbone has receded or been damaged, it becomes unstable and cannot support implants. In such cases, bone grafting is recommended before the restoration.

Factors that can affect jawbone volume include:

  1. Periodontal Disease: This condition can damage the jawbone that supports the teeth, leading to instability and bone loss over time.

  2. Tooth Extraction: After a tooth extraction, studies show that 40-60% of the bone surrounding the extraction site can be lost within three years, resulting in a bone defect.

  3. Injuries and Infections: Physical injuries to the jaw or infections can cause the jawbone to recede, similar to the effects of periodontal disease.

It's important to address these factors and consider bone grafting to ensure a stable foundation for successful dental restorations.

Reasons for bone grafts

Bone grafting is done for several reasons:

  1. Dental Implants: It helps create a strong foundation for dental implants when the jawbone lacks volume or has been damaged.

  2. Ridge Preservation: After tooth extraction, it preserves the jawbone's shape and prevents bone loss.

  3. Sinus Lifts: In the upper jaw, it increases bone height to accommodate dental implants by lifting the sinus membrane.

  4. Correcting Bone Defects: It fills bone defects caused by trauma, infections, or developmental issues.

  5. Aesthetic Enhancements: It improves the appearance by restoring natural jawbone contours and facial features.

Bone grafting supports dental treatments, improves functionality, and enhances oral health and aesthetics.

What Does Bone Grafting Involve?

Bone grafts are used in dental procedures to add bone to an area that needs support or to prepare for dental implants. There are different types of bone grafts:

  1. Autogenous Bone Graft: Bone is taken from the patient's own body, usually from the lower jaw or chin. This method is preferred because it has reliable results.

  2. Allograft Bone Graft: Cadaver or synthetic bone is used for the graft.

  3. Xenograft: Cow bone is used for the graft.

During the surgery, the dentist will numb the area with local anesthetic. They will make a small incision and place the new bone, securing it in place. Sometimes, a synthetic membrane is used to cover the bone and promote new bone growth. The procedure doesn't require an overnight stay, and you will receive instructions for post-operative care. Medications will be prescribed to manage infection, discomfort, and swelling.
