Treatment of Gingival Fenestration With a Double Pedicle Flap Approach and Dehydrated Amnion-Chorion Membrane: A Case Report
Introduction: Although gingival fenestrations (GFs) occur with relative infrequency, their actual incidence is thought to be much higher. Furthermore, if left untreated, these mucogingival defects can lead to unfavorable sequelae which can compromise the esthetics and stability of the teeth affected. Most GFs require surgical treatment for closure. Previously reported modalities of treatment include connective tissue grafting, acellular dermal matrix allograft, and pedicle flap approaches. This case demonstrates the first documented use of a dehydrated amnion-chorion membrane (dHACM) to treat GF. Case Presentation: A surgical approach involving a double pedicle flap and dHACM with 15 months follow-up is described. Following gentle cleansing of the defect and careful split-thickness elevation of a double pedicle flap, the area of exposure fenestration was covered with dHACM. The overlying flap was then closed carefully to completely cover the dHACM. The case presented shows a successful clinical outcome as characterized by successful closure of the fenestration defect with nice tissue maturation. Conclusion: The technique described in this case report demonstrates that GFs can be successfully treated with a periodontal plastic surgical approach using dHACM with minimal patient discomfort.
