Bone Graft

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.

Success rate

Various factors

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.

Material for bone graft

Bone & alternatives

The bone graft's material can be bone from your chin, hip, or shin (autologous, autogenous); from cadaver (allograft) or cow (xenograft); or from a synthetic process (alloplastic).

The body naturally replaces the bone graft material on its own, as the surrounding bone regenerates over six months or so. This is one of the remarkable features of bone tissue, the ability to grow back when supported by some scaffolding.

The choice of material depends on your preference and dental needs. For example, you may wish to avoid your own bone, for a simpler surgical experience. Yet if too much jaw bone is missing, you may need your own hip bone, since it contains bone marrow that promotes bone growth.
