Non-surgical periodontal treatment for black triangle

Abstract

Objective: This case report aims to introduce the black triangle therapy in Miller’s Class IV gingival recession. Methods: The patient complained of spacing between the upper and lower teeth causing food accumulation, “long teeth”, and receding gums which were unaesthetic during speaking. Clinical examination of the maxillary and mandibular anterior revealed Miller Class IV gingival recession, large black triangles, no tooth mobility nor pocket probing, and no gingival inflammation signs. Based on clinical and radiograph examination, nonsurgical therapy using gingival mask was the best option. Nonsurgical therapy using gingival mask was made using indirect technique with an elastomeric impression. An extra-soft soft liner was chosen for gingival mask materials. Results: The black triangle was covered. The “long teeth” appearance and hypersensitivity were reduced. Conclusion: Gingival masks is a good and predictable nonsurgical treatment option for treating black triangle in Miller Class IV gingival recession.
