A bone graft is a procedure used to replace or rebuild bone that has been lost, often due to gum disease or after a tooth extraction. The graft acts as a foundation that helps your body grow new bone over time. Bone grafts are commonly used to support dental implants and help keep your jaw healthy. Don`t worry, we don`t get the bone from your jaw! They are commercially available. The best bone graft is an allograft, which your body can recognize and process into your own natural bone. Dr Ash is not fan of synthetic or bovine bone.
