When a tooth is lost, both bone and scar tissue competes for the defect space. The gum scar tissue grows much faster than bone, thus assuming the space. Using a barrier that you cannot see or feel, gum scar tissue is prevented from forming, while the bone regenerates. Bone regeneration is often used to rebuild the supporting structures around the teeth which have been destroyed by periodontal disease. Bone regeneration may be used to rebuild or reshape the jaw bone. Grafts of the patient's own bone or other growth factors may be used, as well as special materials that allow us to form the ideal shape and contour.
