Gingival fenestration defect in the maxillary anterior region treated with coronally positioned flap using platelet-rich fibrin membrane

Abstract

This report describes the management of gingival fenestration of maxillary right lateral incisor using platelet-rich fibrin (PRF) and coronally repositioned flap procedure. Earlier reports have been documented where fenestration defects around implants are treated with PRF. To the best of our knowledge, this is the first case reported with PRF and chronic renal failure in gingival fenestration around natural tooth. Initial oblique incisions were placed on either side of the defect at the level of the cementoenamel junction #12, followed by vertical incisions extending beyond the mucogingival junction into the alveolar mucosa. After flap elevation, recontouring of the irregular prominent bony margin was performed. Thorough root planing was done; freshly prepared PRF was placed over the root surface and sutured; overlying flap was coronally repositioned and sutured with 5-0 silk sutures. The results of the case demonstrated satisfactory healing of the gingival fenestration defect with excellent color, texture match with the surrounding area along with the keratinized tissue formation emphasizing the importance of using PRF as a membrane in esthetically demanding areas. CLINICAL RELEVANCE TO INTERDISCIPLINARY DENTISTRY PRF could be a good option in treating fenestration which provides good healing and color match especially in esthetically demanding areas.
