Periodontal new attachment therapy]

The ultimate goal of periodontal therapy includes not only the arrest of progressive periodontal disease, but also the restitution of those parts of the supporting apparatus which were destroyed by the disease. Regeneration of periodontal structures dissolved because of periodontal disease is the goal of reconstructive periodontal treatment procedures. The achievement of this goal requires the formation of new cementum with inserting collagen fibers of previously periodontitis involved root surfaces possibly with a concomitant regeneration of supporting alveolar bone. Healing, after periodontal therapy, leads to the formation of long junctional epithelium, root resorption, ankylosis, etc. These are repair process and not one of regeneration. But guided tissue regeneration seems to lead to regeneration with active periodontal ligament cells.
