Root Coverage in Miller's Class 3 Gingival Recession using a Laterally Positioned Flap with Advanced PRF: A Two-year Follow-up Case Report

Introduction: Gingival recession, marked by the apical migration of gingival tissue, presents aesthetic and functional challenges. The laterally positioned flap (LPF) technique, often used for localized root coverage, remains effective, particularly when combined with advanced platelet-rich fibrin (A-PRF). Case Report: A 23-year-old male presented with Miller Class III gingival recession on tooth 41, with clinical attachment loss of 4.5 mm and high frenum attachment. A treatment plan involved the revised LPF technique, A-PRF membrane application, and frenectomy. Surgical Procedure: Following patient consent and scaling, a sulcular incision was made, and flaps were elevated. A-PRF was prepared and placed over the exposed root, with the flap secured by sutures. Post-operative Care: The patient received antibiotics and analgesics, with follow-up at 2 years showing a 4 mm gain in clinical attachment level and complete root coverage. Results: The combination of the LPF technique and A-PRF effectively managed Miller Class III gingival recession, restoring both function and aesthetics. Conclusion: This case underscores the efficacy of using A-PRF with the LPF technique for treating gingival recession, offering a reliable approach for restoring the keratinized gingival zone.
