Periodontal plastic surgical technique for gingival fenestration closure.

Gingival fenestration is an opening through oral keratinized tissue, usually unattached, that is observed in thin gingiva with usually thick subgingival calculus deposits. This lesion is seen infrequently but may be more common than has been reported; lack of symptoms may inhibit patient awareness. Because surgical correction usually is not required, there are very few reports in the literature concerning this lesion. The following report describes a case of gingival fenestration and surgical treatment with a connective tissue/periosteal graft.
