N/A Gingival recession. Intervention 1: Intervention group:The VISTA approach begins with a vestibular access incision using 15c scalpel blade. Two vertical incisions will made on both sides of recession area . This is continues at the base of the gingival papillae without affecting their entirety. A microsurgical periosteal elevator (VISTA 1, Dowell Dental Products) will use to create the subperiosteal tunnel with sufficient extension. An elevator with bayonet curves (VISTA 2 and 3, Dowell Dental Products) facilitates access to the gingival sulcus and interproximal areas .The CTG was guided using a horizontal mattress suture within the tunnel by inserting a 3-0 silk suture with a 26-mm 3/8 circle needle. The CTG and mucogingival complex will then advance coronally and stabilize in the new position with a coronally anchore suturing technique using a 6.0 polypropylene suture. Intervention 2: Control group: Two bevelled oblique, slightly divergent, incisions starting at the end of the two horizontal incisions of the distal and mesial teeth and extending to the alveolar mucosa. All of incisions will made with a 15c scalpel blade.The resulting trapezoidal-shaped flap was elevated with in the coronal–apical direction up to exposing 3–4mm of bone apical to the bone dehiscence. The CTG is sutured at the recession area with horizontal double mattress using 6.0 polypropylene suture at the level of buccal CEJ.The gingival margin will advance coronally to the most coronal level of the interproximal papillae.
