Factors Contributing to Jawbone Loss
- Periodontal Disease: Periodontal disease can cause irreversible damage to the jawbone that supports the teeth. As the disease progresses, the affected areas weaken, leading to unstable teeth.
- Tooth Extraction: Research shows that patients who undergo tooth extraction can lose 40-60% of the bone surrounding the extraction site within the first three years, leading to what is referred to as a "bone defect."
- Injuries and Infections: Dental injuries, including blows to the jaw, can result in bone recession. Infections can also lead to similar bone loss, compromising the stability of the jaw.

Reasons for Bone Grafts
- Jaw Stabilization: Bone grafting helps restore and stabilize the jawbone, creating a solid foundation for restorative treatments or dental implants. It can also correct deformities and strengthen the jaw structure, ensuring long-term dental success.
- Preservation: Bone grafting is particularly effective in preventing bone loss after a tooth extraction, periodontal disease, or other invasive dental procedures. By preserving bone density, it helps ensure that your jaw remains healthy and stable, supporting future treatments.
What Does Bone Grafting Involve?
Autogenous Bone Graft
This is the most common and preferred method, where bone is harvested from the patient’s own body, typically from the posterior part of the lower jaw or the chin. This method often provides the most reliable and predictable results.
Allograft Bone Graft
Allograft bone grafts utilize tissue from deceased human donors, meticulously processed and screened for safety within a regulated tissue bank to ensure they are free from disease and suitable for transplantation.
Xenograft
This type of bone graft employs bone tissue derived from animal sources, most commonly cows (bovine). These xenografts are meticulously processed to remove any potentially harmful substances and are designed to be biocompatible with human tissue.
