Successful management of a large mucosal fenestration at 18-months follow-up.
OBJECTIVES: Mucosal fenestrations are infrequent and often challenging to treat depending on the extent of soft and hard tissue destruction. This article presents the successful management of a relatively larger mucosal fenestration associated with complete absence of buccal bone plate in a mandibular incisor secondary to trauma-induced periapical pathosis.
CLINICAL CONSIDERATIONS: After non-surgical endodontic therapy, surgery was performed for debridement of the osseous defect, root resection/shaping, connective tissue graft (CTG) placement on the affected root surface and platelet rich fibrin (PRF) in periapical osseous defect rather than use of bone graft and/or barrier membrane. Healing was uneventful, however, a small mucosal defect remained at 2 weeks follow-up. After 3 months of primary surgery, a corrective surgery was performed utilizing an "incision-free" approach i.e. tunnel technique with CTG in contrast to the contemporary flap approach. At 18 months follow-up, complete closure of the mucosal defect with a thick gingival biotype, normal sulcus depth, and good esthetic outcome were achieved. No recurrence and any clinical signs of infection or inflammation were observed.
CONCLUSIONS: Based on the outcomes of present case, an early intervention utilizing the minimally invasive surgical therapy and autologous biomaterials may be considered a viable approach to treat such complex lesions.
CLINICAL SIGNIFICANCE: Endodontic therapy in combination with PRF and CTG appears to provide successful outcomes in treatment of a large mucosal fenestration with periapical osseous defect.
