Dental bone grafting is performed to build up the height or thickness of the jawbone. In cases where the jaw bone is damaged or receded (shrunken), bone grafting is performed to prepare for dental implant placement or other procedures requiring bone support. Having a large bone volume at a dental implant site means that we are able to place a bigger and wider implant, which would increase strength and stability. A bone grafting appointment, performed in this manner, is a relatively quick and comfortable procedure that can be completed right in the dental office.
Jaw bone volume can be insufficient for a number of reasons:
Periodontal (gum) disease and infections – when prolonged bacterial attacks occur at or under the gum line, our gums and underlying bone eventually begin retreating. This results in a permanent and irreversible loss of bone that can only be partially regained through surgery.
Tooth extraction – following a tooth extraction a person will lose 40-60% of the bone surrounding the tooth site within three years. Socket preservation surgery (a particulate bone graft) can be performed to minimize immediate bone loss and maintain the area for a period of time for planned dental implant placement or other restorations.
Injury – trauma to the jaw or other dental injuries can cause bone loss.
