[Progressive gingival recession: a 2-stage surgical technic].

A technique for treating gingival recession which provides a means of achieving two objectives, interrupting the disease process and aesthetic covering of the exposed root, are described. A two step procedure is used: 1) a free submarginal gingival graft is positioned high enough to attach the gum, 2) the exposed root is covered with a bipediculated crown flap. A biological glue was used instead of suture after preparing the root surface with citric acid.
