Surgical procedure

In Group A, CAF was reflected to prepare the recipient site. Horizontal incisions were made in the mesial and distal interdental papilla of the involved tooth at the level of CEJ. Apically divergent vertical incisions were made extending into the alveolar mucosa. An intrasulcular incision was given that would connect horizontal and vertical incisions. A full-thickness flap was raised 3–4 mm apical to the crest of the defect, beyond which, a partial-thickness flap was raised as shown in Figure 5.[15] Required amount of PRF membrane was then placed on denuded root surface.

Surgical procedure of coronally advanced flap with platelet rich fibrin membrane (a) Placement of horizontal incision joined with vertical incision and sulcular incision was placed; (b)following a full- split- full thickness flap was raised; (c) Platelet rich fibrin (PRF) membrane was placed on the gingival recession defect; (d) direct interrupted suture was placed; (e) tin foil placed and (f) periodontal pack was placed on the surgical site
