Do I Have Enough Bone?

Do I Have Enough Bone

After tooth extraction, if the walls of the socket are very thick, they will usually fill naturally with bone in two to three months. However, when the walls of your socket are very thin (such as in your upper and lower front teeth), this type of healing will not be as predictable In these situations, a bone graft is often placed at the time of tooth extraction to help your body fill in the empty socket with bone. This type of graft is called a Socket Preservation Graft. It is a simple procedure involving a commercial bone graft material and a membrane.  This step will maintain the width and volume of the socket for implant placement several months later

There may be inadequate bone for implant placement if your tooth was removed many years ago and your bony ridge is extremely thin. In this case, a bone graft can be placed next to the thin bone and allowed to heal for up to six months. This type of graft is called an Onlay Graft and will most likely be done utilizing your own bone- obtained from the back part of the jaw. After 3-6 months and the graft has fused to your jaw, the ridge will be re-entered and an implant can be placed. Bone grafting is usually a relatively comfortable office procedure

Graft Material and Implant PlacedYou may also need bone grafting if the sinus cavities in your upper jaw are very large, or very low, and extend into the tooth-bearing areas. This often occurs when teeth in the back of a person’s upper jaw have been removed many years before, and the amount of bone available for implant placement is limited. A Sinus Graft procedure is then required. Most often, it is performed in the office with local anesthesia and perhaps sedation. During this procedure, the membrane that lines the sinus will be located and elevated. Bone will then be added to restore the bone height and ensure that dental implants of an adequate length can be placed. This procedure often can be also be performed at the time of implant placement
