Gingival recession is defined as the apical shift of the marginal gingiva from its normal position on the crown of the tooth to levels on the root surface beyond the cemento-enamel junction (CEJ).Various surgical procedures including repositioned flaps as well as autogenous and other type grafts have been used in the treatment of gingival recession.The present gold standard technique is the bilaminar technique using the subepithelial connective tissue graft (SCTG) which provides for long-term stability but also increases tissue morbidity.Hence, a suitable alternative technique - the periosteal pedicle flap (PPF) - has been practiced, which is less invasive, does not require a second surgical site, and provides a graft of adequate dimensions.
