Occasionally, there is not sufficient bone present to allow insertion of implants.  Bone grafts are also occasionally necessary to fill in gaps during facial reconstruction surgery.  There are several techniques that can be utilized.  Bone can be removed from an alternate location in the jaw and moved to the deficient area. Alternately, mineralized bone or other bone substitutes can be utilized.  These products are specially treated and sterilized so that they can be utilized in the human body.  Mineralized bone is an inert calcified matrix into which your own bone can grow.  If a large volume of bone is required for grafting, it may be necessary to obtain bone from an area other than the jaw.  If a remote bone graft site is required, we will discuss this with you in detail.  If it is necessary to harvest bone from a remote site, we will usually utilize hip bone to obtain the graft material.
Patients who have difficulty wearing dentures, do not have enough bone for implant placement or have other jaw defects, can benefit from jaw reconstruction surgery.  Bone and soft tissue can usually be added to the jaws so that dentures can be worn successfully, implants can be inserted and aesthetics restored.

Minor bone grafting can be done in the office under local or general anaesthesia.  Larger bone grafts are done in the hospital under general anaesthesia and are covered by OHIP.

The success of bone grafts is enhanced with the utilization of platelet rich plasma.  Platelet rich plasma is a solution derived from a small amount of your own blood.  The blood is centrifuged to concentrate blood cells which are called platelets.  Platelets contain growth factors that aid in healing.  The solution containing the growth factors is mixed into the bone graft.

General anaesthesia is often recommended for bone graft procedures.
