[A classification of parodontal surgical procedures (author's transl)].

Parodontal surgery is a dynamic entity, which has evolved in a continuous manner since the beginning of the century, because of the increasing interest in parodontology itself, the growing importance of surgical treatment for parodontal diseases, and improved knowledge of biological processes involved in cicatrization. A new classification is suggested which should allow a more specific selection of indications for surgical treatment and thus to obtain a stable and long-lasting result.
