Bone grafting
is the replacement or augmentation of the portion of the jaw bone that anchors the teeth. It's a surgical procedure that's often done to reverse the loss or resorption of bone that may have occurred due to tooth loss, trauma, disease or ill-fitting dentures, and to rebuild the bone structure beneath the gums in preparation for the placement of dental implants or other tooth replacements.
When bone graft is implanted in the jaw, it doesn't just simply fill a void in the bone; it may also help promote new bone growth in that location. When successful bone grafting can restore both the height and width of your jaw bone.
