Over a period of time, the jawbone associated with missing teeth atrophies or is resorbed. This often leaves a poor quality and quantity of bone for placement of dental implants. Today we can grow new bone, where needed. This not only allows the replacement of missing teeth with dental implants, but gives us a chance to restore esthetic appearance.
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip, or tibia (below the knee). In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.
