Abstract

In this case report, gingival recession of the mandibular anterior teeth was treated with a laterally closed tunnel technique. Two patients had altered the inclination of mandibular anterior tooth during past orthodontic treatment and had periodontal thin biotype. The recipient site was formed by tunneling method, and the connective tissue graft obtained from the palatal side was placed in the tunnel, and the margins of flap were gathered at the center of the root and sutured. Despite the thin periodontal biotype, the root coverage was successfully obtained, keratinized gingiva was increased, and aesthetics were achieved by harmonizing with surrounding tissues in terms of shape and color.
