Types of Bone Grafting
Some of the most common types of bone grafting include:
The maxillary sinuses are air-filled spaces above the upper jawbone. A loss of bone in this area requires a special bone-grafting procedure called a “sinus lift” to rebuild the bone in preparation for a dental implant. Also known as “sinus augmentation”, this common procedure is done by raising the sinus membrane and placing bone-grafting material underneath it. This procedure has revolutionized care for those with no upper teeth who would like a more comfortable and convenient option than dentures can provide.
When a tooth is extracted, it leaves behind an empty socket. Because there is no tooth to stimulate the jawbone, the socket may expand as the jawbone resorbs due to lack of use. Socket preservation is a preventative measure that is performed by implanting bone grafting material at the same time as extraction to preserve the jawbone for future tooth replacement.
Ridge augmentation is similar to socket preservation in that it involves the repair of the bone underneath an empty tooth socket. However, instead of being done at the same time as extraction (as with socket preservation), it is performed after bone resorption has already occurred. The treatment involves the implanting of bone grafting material in the site to act as scaffolding for new bone growth.
Nerve repositioning is the process of moving the inferior alveolar nerve to make room for dental implants in the lower jaw. During the procedure, the nerve is moved out of the way for implant installation and then replaced. The pockets are then filled with bone grafting material to bulk up the jawbone. Because this nerve is responsible for feeling in the lower lip and chin, there is often postoperative numbness, which can sometimes be permanent. For this reason, it is considered to be an aggressive treatment choice and requires very careful consideration.
The process of bone grafting has opened up a world of possibilities when it comes to the replacement of missing teeth. Call Dr. Wasson, Dr. Wang and Dr. Amini at Seattle Office Phone Number 206-632-0220 to see what bone grafting can do for you!
