Clinical Evaluation of the Amount of Root Coverage Following The Use of VISTA Technique Versus Coronally Advanced Flap in Combination With Subepithelial Connective Tissue Graft for Management of Multiple Gingival Recessions

Patients with multiple recession defects will be randomly oriented into to groups. The test group will recieve a relatively new technique, the VISTA technique, combined with connective tissue graft that will be harvested from the palate. The control group will recieve coronally advanced flap with connective tissue graft. subjects will be followed up for 6 months after the surgery. Any complications, that may occur, will be dealt with.
