Preserving Your Jaw Bone after Extraction
Removal of teeth is sometimes necessary because of pain, infection, bone loss, or a fracture in the tooth. The bone that holds the tooth in place (the socket) is often damaged by disease and/or infection, resulting in a deformity of the jaw after the tooth is extracted. In addition, when teeth are extracted the surrounding bone and gums can shrink and recede very quickly, resulting in unsightly defects and a collapse of the lips and cheeks.
These jaw defects can create major problems in performing restorative dentistry whether your treatment involves dental implants, bridges, or dentures. Jaw deformities from tooth removal can be prevented and repaired by a procedure called socket preservation. Socket preservation can greatly improve your smile’s appearance and increase your chances for successful dental implants.
Several techniques can be used to preserve the bone and minimize bone loss after an extraction. In one common method, the tooth is removed and the socket is filled with bone or bone substitute. It is then covered with gum, artificial membrane, or tissue, which encourages your body’s natural ability to repair the socket. With this method, the socket heals, eliminating shrinkage and collapse of the surrounding gum and facial tissues. The newly formed bone in the socket also provides a foundation for an implant to replace the tooth.
Crestal Sinus Elevation For Implant Placement
The maxillary sinuses are behind your cheeks and on top of the upper teeth. These sinuses are empty, air-filled spaces. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.
The key to a successful and long-lasting dental implant is the quality and quantity of jaw bone to which the implant will be attached. If bone loss has occurred due to injury or periodontal disease, a sinus augmentation can raise the sinus floor and allow for new bone formation. A sinus lift is one of the most common bone grafting procedures for patients with bone loss in the upper jaw. The procedure seeks to grow bone in the floor of the maxillary sinus above the bony ridge of the gum line that anchors the teeth in the upper jaw. This enables dental implants to be placed and secured in the new bone growth
A common use of bone grafting is for ridge augmentation. Ridge augmentation can recapture the natural contour of your gums and jaw after the loss of a tooth as a result of trauma, congenital abnormalities, infection, or periodontal disease. Achieving an ideal amount of gum and bone as a support to surrounding restorations or implants may require hard and soft tissue reconstruction.
After the loss of one or more teeth, your gums and jawbone may resorb resulting in an indentation where the tooth or teeth used to be. This occurs because the jawbone recedes when it no longer is holding a tooth in place. Not only is this indentation unnatural looking, it also causes the replacement tooth to look too long compared to the adjacent teeth, and this can create an area that is difficult to keep clean.
Ridge augmentation uses bone and tissue-grafting procedures to fill in the indented area of the jaw and gums, leaving you with a smooth gum line that coexists with your restoration or dental implant.
The alveolar ridge bone is a special type of bone surrounding and supporting the teeth. When a tooth has been removed, this bone begins to deteriorate. It can also lose density due to natural breakdown from age, or from disease.
Ridge expansion is performed when the jaw is not wide enough or high enough to support implants. The bony ridge of the jaw is increased by splitting the bone with surgical instruments. Bone graft material is inserted and allowed to heal before placing the implant. In some cases, the implant is placed when the ridge is split.
The surgery is typically performed in the office under regular local dental anesthetic
