Bone Grafting for Dental Implants
Do I have enough bone for dental implants?
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 step will maintain the width and volume of bone you will need for implant placement several months later.

There may be inadequate bone for dental 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 ridge will be re-entered and the implant placed. Bone grafting is usually a relatively comfortable office procedure. When rebuilding this lost bone – Dr. Loetscher firmly believes it should be replaced by bone from your own body. This maintains the success rate of your dental implants in the 98% and higher. The source of this bone may be your jawbone, your hip, and nowadays – tissue re-engineered bone utilized growth factors that turn on your own stem cells. The growth factors eliminate using your own bone.

You 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 lift grafting procedure” is then required. This is a very straightforward and successful procedure, well tolerated. 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 performed at the time of implant placement.
