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 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.

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 ridge will be re-entered and the implant placed. Bone grafting is usually a relatively comfortable office procedure. Many different bone-grafting materials are available, including 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 grafting 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 performed at the time of implant placement.
Straumann® AlloGraft Ring Vancouver BC
Processed human allogenic bone ring.
A prefabricated ring of processed allogenic donor bone that is placed press-fit into a trephine drill-prepared ring bed. This is an innovative solution for 3-dimensional vertical augmentation of bone defects allowing a single-stage graft and implant placement. The simultaneous implant placement saves you and your patient time and a surgical step compared to a conventional bone block, reducing chair time compared to a bone block, eliminating the need for a second harvesting site and shorter time-to-teeth. Dr. Noroozi is one of very few implant surgeons in North America who has been trained formally by Dr. Giesenhagen from Germany to perform this advanced procedure.
