Abstract

Abstract: Objective: This case report presented the treatment of the black triangle of the maxillary anterior teeth, hoping to provide a new idea for the treatment of the black triangle. Diagnosis and treatment: Female, 33 years old. The height of the maxillary anterior gingival papilla reduced for more than 1 month. This case was treated with tunnel technology (TUN) +connective tissue graft (CTG) combined with resin restoration to treat the gingival papilla recession. The patients were followed up for 2 years. Results: After 2 years, the shape of gingival papilla in anterior teeth area was plump, the interproximate space was completely filled, and the esthetic effect was significantly improved. Conclusion: TUN+CTG combined with resin restoration can be used to treat the black triangle of anterior teeth. Its indications, advantages and disadvantages need to be proved by further clinical research.

Key words: black triangle, tunnel technique, resin restoration, connective tissue graft
