Common cosmetic failures in guided tissue regeneration (GTR) procedures performed in the esthetic zone include an unacceptable postoperative recession of the gingival flap and loss of the papillae. This article describes the dynamics of flap healing that contribute to esthetic failures. Specific technique modifications of GTR procedures that enhance the predictability of successful functional and esthetic outcomes are described.
