L-PRF Versus Connective Tissue Graft Associated to Coronally Advanced Flap in Gingival Recession Treatment

The Coronally advanced flap was made following the protocol described by Zucchelli et al. in 2007. (39). When the margin of the flap was able to passively extend until more coronal of the CEJ the coronal mobilization of the flap was considered satisfactory. A double L-PRF membrane was positioned at the level of CEJ, getting the stabilization with 5-0 resorbable suture. After that, the flap was coronally advanced and stabilized with interrupted sutures (5-0 resorbable) anchored to incisal contact points (mesial and distal) created with a flowable, light-curing resin material in the treated tooth. Finally, gentle pressure over the area with a moistened gauze with saline solution was performed.
