A bone graft is to build up jaw bone that is missing or shrunken.
Ageing, denture use, missing teeth, gum disease, trauma, tooth extractions and dental implants may call for bone grafting.
Why a bone graft?
Implants & youthfulness
Bone grafts are most commonly required by dental implants, which require a strong enough jaw bone as foundation. This foundation is often missing for the very reason the dental implant is being sought. For example, trauma has damaged the jaw bone, or a long missing tooth has shrunken the jaw bone.
Bone grafting can make a face more youthful. When jaw bone has shrunken, due to ageing or missing teeth or gum disease, the face looks sunken and older.
With high probability, a bone graft succeeds and the body accepts it. In case of failure, a new bone graft may be in order. Certain factors do compromise the success rate, such as smoking. Age is not a risk factor, it seems.
