[Is connective tissue reattachment on root surfaces exposed to the oral environment possible?]

In advanced periodontal diseases, where the root surface a longer time is exposed to the oral environment, retaining of teeth is only possible through de novo-attachment of the periodontal ligament on the diseased root surface. Even when surgical reconstruction of the alveolar bone is successful, connective tissue fibers fail to attach to the affected dental cementum. Patients with two- and three wall pockets can be successfully treated by Nymans method of guided tissue regeneration. However the restoration of the dental attachment apparatus in cases with advanced horizontal destruction of the alveolar bone is still an unsolved problem of periodontal therapy. Investigations of an artificial attachment support will be presented. A synthetic felt glued onto the root surface with special dental adhesives shall obtain the necessary support reattachment of the connective tissue fibers at the periodontitis affect root.
