[Partially buried connective tissue grafts for gingival recession: clinical results apropos of 22 cases].

Abstract

A connective tissue graft technique described by Langer and Langer for treating gingival recession was attempted in 22 clinical cases using connective tissue above. 100% root coverage was obtained where only 3 mm of recession existed, 94% when recession was 3 to 5 mm and 58% root coverage occurred where recession was greater than 6 mm. This technique was compared with the classical technique of free gingival grafts and the connective tissue graft technique for covering exposed root surfaces proposed by Nelson.
