An unavoidable consequence of periodontal flap procedure is gingival recession (GR). Achieving both pocket depth reduction and GR coverage remains a challenge to periodontists. The present case report provides a new innovative technique that will enable all clinicians to achieve pocket depth reduction as well as recession coverage in esthetic zone. The clinical parameters that were assessed at baseline, 1 month, 3 months, and 6 months are probing depth (PD), clinical attachment level (CAL), height of GR (HGR), and gingival biotype. The patient reported with a faulty post and core with crown in relation to maxillary right central incisor with a PD of 8 mm and HGR of 2.5 mm. Following replacement of the crown with respect to the tooth, semilunar incision was made and flap was reflected to visualize the underlying bone. This technique does not involve the interdental papilla at the same time allows the coronal advancement of the flap. A chorion membrane was placed to accelerate the healing as well to provide stable clinical outcome. The patient was evaluated at 10 days, 1 month, 3 months, and 6 months. There was a considerable reduction in PD, GR, and thus gain in CAL. The results remained stable over a period of 6 months.
