Aim: The aim of the current study was to compare the esthetic results for subjects with Miller Class I and II gingival recession (GR) abnormalities using platelet-rich fibrin (PRF) membrane with coronal advanced flaps (CAFs) with and without vertical releasing incisions (VRIs; the envelope-type flap and the flap with VRIs).
Materials And Methods: Seven defects from each of the test and control groups made up of fourteen defects total. In the test group, PRF + CAF was performed without VRI, while in the control group, VRI was used.
