As periodontal disease progresses, pockets of degenerated bone develop in the jaw. These pockets can promote the growth of bacteria and the spread of infection. To address these pockets Osseous and Tissue regeneration is the recommended. During this procedure, the pockets are cleaned thoroughly, and a membrane is installed between the soft tissue and the pocket in the bone. Some of these membranes are bio-absorbable and some require removal. The membrane covers the pocket so that fast-growing soft tissue is blocked, and slower-growing bone can begin to grow, or “regenerate” itself.
