Bone Grafting for Implants
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 three to four months. However, when the walls of your socket are very thin (such as in your upper and lower front teeth), 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 step will maintain the width and volume of bone you will need for implant placement several months later.
1. Inadequate Bone
2. Graft Material Placed
3. Implants Placed
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. After the graft has fused to your pre-existing bone, the implant can then be placed. Bone grafting is usually a relatively comfortable office procedure, and many different bone-grafting materials are available.

You may also require 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 grafting procedure” (also known as a “sinus lift”) is then required. Most often, it is performed in the office with IV sedation or local anesthesia. 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.
