In preparation for dental implants
Over a period of time, the jawbone associated with missing teeth resorbs or becomes thinner. This often leaves a condition in which there is not enough suitable bone for placement of dental implants. Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width it also gives us a chance to restore functionality and esthetic appearances. 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 used. The grafts typically need to heal for 3-6 months before proceeding with the implants. There are many sources of bone graft material including yourself, humans, cows, and synthetic substances.
Around natural teeth
Periodontal disease can destroy the supporting bone surrounding teeth. In certain situations, bone grafts can be done around teeth to regain some lost bone. This is called guided tissue regeneration.
