Repair of Lingual Gingival Fenestrations Through the Use of a Subepithelial Connective Tissue Graft

A gingival fenestration is a localized perforation of keratinized gingival tissue that may result in underlying bone resorption and root exposure. This case report describes treatment of mandibular lingual gingival fenestrations caused by traumatic forces from an ill-fitting removable partial denture that rested on a thin periodontal phenotype. A subepithelial connective tissue graft was used to correct these fenestrations. At the 2-year follow-up, the gingival tissues presented in a state of health.
