Abstract

Dental therapy in general and periodontal therapy in particular is directed increasingly at the esthetic outcome for patients. Gingival recession is one of the most common esthetic concerns associated with periodontal tissues. Although various treatment modalities have been developed, subepithelial connective tissue grafting remains the most successful and predictable technique for treatment of gingival recession. Harvesting a connective tissue graft from the palate is many times not only traumatic, but also very painful for the patient. Use of single incision to harvest the subepithelial connective tissue graft is one of the least traumatic, but relatively difficult technique to accomplish. This article presents a modified single incision technique, which is not only less traumatic and painful, but comparatively simple to employ and master. Two new instruments have been introduced to make harvesting of the connective tissue graft easier.

Keywords: Cementoenamel junction; connective tissue; gingival recession; grafts; subepithelial.
