Dental bone grafting is an oral surgical procedure done by an oral surgeon to support the bone where it is missing and needed. The need for a bone graft comes when the jawbone associated with missing teeth atrophies or is reabsorbed.
An impacted tooth is a tooth that is unable to emerge through the gum line due to the positioning of the tooth, dense soft tissue, bone, or another tooth. The most common and known situation is the wisdom tooth.
Orthognathic surgery (corrective jaw surgery) is needed to reposition a misaligned jaw to function properly and allows the teeth to meet correctly. Jaw surgery may dramatically enhance your facial features as well.
