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.
牙周瓣手术不可避免的后果是牙龈退缩（GR）。实现牙周袋深度降低和牙龈退缩覆盖对牙周病医生来说仍然是一个挑战。本病例报告提供了一种新的创新技术，使所有临床医生能够在美学区域实现牙周袋深度降低以及退缩覆盖。在基线、1个月、3个月和6个月时评估的临床参数包括探诊深度（PD）、临床附着水平（CAL）、牙龈退缩高度（HGR）和牙龈生物型。患者上颌右中切牙的桩核冠修复不当，牙周袋深度为8mm，牙龈退缩高度为2.5mm。对该牙进行冠修复后，做半月形切口并翻瓣以观察下方的骨组织。该技术不涉及龈乳头，同时允许瓣向冠方推进。放置绒毛膜以加速愈合并提供稳定的临床结果。在10天、1个月、3个月和6个月时对患者进行评估。牙周袋深度、牙龈退缩有显著降低，临床附着水平增加。结果在6个月内保持稳定。
