Restoration of gingival and esthetic deformities following flap advancement: the physiologically pigmented gingival graft--a case report.

The coronal advancement of surgical flaps and subsequent shift of the mucogingival junction during bone augmentation procedures are common. These mucogingival alterations may become a challenge to manage in the maxillary anterior region among patients with a high lip line upon smiling or high esthetic demands. To further complicate matters, the presence of physiologic gingival pigmentation in the esthetic zone creates challenges of its own. In this case, a free gingival graft from the buccal gingiva of the maxillary molars was used to correct the mucogingival deformity created from a guided bone regeneration procedure.
