After the administration of local anesthesia, root planing of the exposed root surfaces will be performed by means of hand instruments.

A partial thickness envelope is performed with tunneling instruments involving one or two teeth adjacent to the tooth, in case of a very thin biotype a complete thickness envelope could be done.

Two horizontal incisions are done at the base of the papillae of the deepest recession site, allowing to place the graft in a more coronal position and improving access and visibility.

Immediately before surgery, contact point composite stops were placed to prevent the collapse of the suspended sutures in the inter-proximal spaces.• The entire gingival papillary complex will be moved coronally using a suspended suture anchored in the lingual gingiva (Aroca et al., 2010, 2013; Azzi et al, 2002, zuhr et al.,2009).

Modified laterally stretched technique with a connective tissue graft.

Measured as the difference between the recession gingival depth at different follow up intervals and the baseline.

(Preoperative vertical recession - Postoperative vertical recession/preoperative vertical recession) x 100

Measured as the distance between the free gingival margin and the cemento-enamel junction .
