Minor and Major Bone Grafting
Over a period of time, the jaw bone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates 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 aesthetic appearance.
Minor bone grafting
Bone grafting at the time of tooth extraction, known as socket preservation, is accomplished to preserve the bony ridge form for implant placement. It also helps to maintain tissue esthetics.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. This process is know as ridge augmentation. Sinus bone grafts (lifts) are also performed to replace bone in the posterior upper jaw. 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.
