Dental bone grafting is a specialized oral surgical procedure that has been developed to reestablish lost jawbone. This loss can be a result of dental infection of abscess, periodontal disease, trauma, or the natural process of aging. There are various reasons for replacing lost bone tissue and encouraging natural bone growth, and each technique tackles jawbone defects differently. Reasons that bone grafting might be needed include sinus augmentation, socket preservation, ridge augmentation, or regeneration. There is currently some evidence supporting the use of autologous platelet concentrates (cell fragments containing growth factors to promote tissue regeneration) when bone grafting is used to treat gum disease.
