Coverage of Multiple Mandibular Gingival Recessions Using Tunnel Technique with Connective Tissue Graft: A Prospective Case Series.

Abstract

The aim of this clinical case series was to evaluate the clinical performance of the modified tunnel technique for treatment of multiple gingival recessions in the anterior mandible. A total of 20 patients with 63 Miller Class I and II defects were treated via a modified tunnel technique with subepithelial connective tissue graft. At baseline and 6 months postoperative, recession depth, probing pocket depth, width of keratinized tissue, and gingival tissue thickness were assessed. At 6 months, the results revealed a mean recession coverage of 93.87%. Complete recession coverage was achieved in 74.60%. The mean reduction of recession depth was 2.79 ± 0.12 mm. The modified tunnel technique showed successful mean root coverage in the delicate anterior mandible and was able to increase the amount of keratinized tissue.
