During implant reconstruction, bone grafting becomes necessary if your upper or lower jawbones do not have enough volume to support the titanium posts. This usually results from periodontal disease, injuries, cysts, infections, or an extracted tooth. Bone grafting restores your previous bone structure by actually growing bone or replacing it with a synthetic material.
It can usually be determined through an X-ray and clinical exam whether a bone graft is needed, although sometimes the problem is not discovered until the implant site has been opened.
The procedure is safe and effective.
Best results are usually achieved using allogeneic bone which is bone taken from other people and frozen or stored in tissue banks, or using an autogenous bone graft which is the patients’ own bone from the jaws, hips, or ribs. A variety of natural and synthetic replacement materials can be used instead of bone. Another method for promoting bone formation is through the “Barrier Membrane Technique.” The membranes are made out of special materials placed over the bone graft site in order to promote growth and cell migration, which creates healthy bone. The membranes may resorb into the body or need to be removed at a later date. “Screws” and “tacks” may also be used and later removed.
