Guided tissue regeneration and a free gingival graft for the management of buccal recession: a case report.

Five patients with buccal gingival recession (4 to 6 mm) underwent surgical treatment consisting of a guided tissue regeneration procedure associated with a free gingival graft. The graft was used to cover the newly formed tissue on the root surface at the reentry. Root coverage was complete in three patients, while 1 mm of recession remained in the other two patients. The free gingival graft reconstructed the keratinized tissue, which had been lost because of recession. Moreover, it allowed the mucogingival junction, which had been displaced coronally during the first surgery, to be realigned, therefore preventing a shallowing of the vestibule.
