The bone grafting procedure is usually performed during dental restorations such as dental implants or bridges. It’s done in order to shore up the jawbone that has either receded or has a high degree of damage, so that there’s a stable foundation for the implant or bridge to be successfully placed. It is also done in order to limit or prevent the jawbone from receding even further, which can happen after periodontal disease or a tooth extraction.
There are a few different types of bone grafts. The most common ones are: Autogenous Bone Graft - this is when the bone is taken from the patient’s own body, usually from the chin or the rear (posterior) of the lower jaw. This is the preferred method, since it produces the most predictable results. Allograft Bone Graft - synthetic bone, or bone from a cadaver is used Xenograft - cow bone is used
The bone graft procedure often takes several months and is usually done under local anesthetic. If the amount of bone that needs to be grafted is large, general anesthesia may be required. If an autogenous bone graft is performed, the bone is harvested from your own body and added to the affected site, where it will fuse with the existing bone over time. During the surgery, an incision is made to prepare the site for the addition of the new bone, and it is anchored into place. A synthetic membrane may be used to cover the new bone, preventing soft tissue and bacteria from invading the site, and encouraging new bone growth.
