Gingival recession is clinically manifested by an apical displacement of the gingival tissues, leading to root surface exposure. An array of therapeutic options are available for treatment of gingival recession defects, though many of these are better suited for treatment of isolated defects. Some of the limitations of current techniques include the need for harvesting of autogenous donor tissues and their associated morbidity, as well as scar formation at the recipient site resulting from surface incisions. Moreover, muscle pull during healing often leads to incomplete root coverage or relapse of the recession. To overcome this, an alternative method for root coverage of incisors is introduced i.e vestibular incision subperiosteal tunnel access (VISTA technique)
