Increasing Width of Attached Gingiva Using Modified Apically Repositioned Flap Technique Combined With Platelet-Rich Fibrin: A Case Report.

Adequate attached gingiva is cardinal for periodontal health maintenance. It helps to prevent apical migration of the gingival margin and serves as a stable barrier against plaque accumulation and plaque-induced inflammation of the gingiva. To increase attached gingiva, many techniques have been used. The modified apically repositioned flap (MARF) technique is considered one of the simplest methods to increase attached gingiva. In this technique, a partial-thickness flap is elevated using a single horizontal incision and then repositioned apically, which results in the exposure of the periosteum. This exposed periosteum may cause postoperative discomfort to the patient. To overcome this, platelet-rich fibrin (PRF) is placed over the exposed periosteum to promote healing and reduce postoperative discomfort. This case presentation addresses the amelioration of the width of the attached gingiva using MARF combined with PRF.
