Gingival recession is defined as apical migration of the junctional epithelium with exposure of root surfaces. It is caused by many factors such as traumatic toothbrushing, periodontitis, high muscle and frenulum attachments, tooth malposition, thin or incomplete bone and soft tissue, traumatic bite, grinding and clenching of teeth, piercing, hormonal changes and iatrogenically caused gingival recessions whit ortodontic, prosthodontic, restaurant and periodontics treatment. Gingival recessions are treated by removing the etiological causes and with surgical therapy. Surgical techniques can be divided into pedicle soft tissue grafts techniques and free soft tissue grafts techniques. Pedicle soft tissue grafts techniques can be divided into rotational or laterally positioned flaps techniques, coronally positioned flap techniques and guided tissue regeneration techniques. Free soft tissue grafts techniques uses epithelialized and subepithelial tissue grafts. The choice of surgical technique depends on the design of the recession and the surrounding tissue and the skill of the surgeon. Tunnel technique was developed as a modification of envelope technique for covering multiple and individual recessions. It involves the use of free soft tissue graft, usually taken from the palate, which is passed through the tunnel made without flap elevation and the use of disburden incision. The advantages of this technique are better wound healing, less traumatising tissues, minimal risk of losing papilla height and harmony of colors and textures of gingiva. The main disadvantage of this technique is a complexity of performance ie, the risk of perforation of the flap and the difficulty in fixing and stabilization of the graft.
