Abstract
A guided tissue regeneration procedure was used to treat human buccal recessions, 3 to 7 mm deep, in 12 patients. No procedure for increasing the width of keratinized tissue was performed prior to treatment. A thick bipedicled flap was raised with a semilunar incision in the alveolar mucosa and a marginal incision was extended to the adjacent papilla. The root surface was made concave by curets and burs to create space for regeneration. The membrane was fixed to the cemento‐enamel junction and covered by the flap which consisted of the residual gingiva and of alveolar mucosa. The membranes were removed 4 weeks after placement. The patients were recalled 6 months after the reentry procedure. The average reduction in recession was 2.50 mm (P P J Periodontol 1992; 63:554–560.
