Connective tissue grafting employing the tunnel technique: a case report of complete root coverage in the anterior maxilla.

Techniques for surgical root coverage have been continuously revised over the past few decades. With increased knowledge on the etiopathogenesis of gingival recessions and on the repair/regeneration mechanisms of deep and superficial periodontal tissues, procedure simplification has been possible, and more predictable and stable results have been obtained. The maintenance of maximal blood supply has brought major changes in flap design. The coverage of contiguous recessions on the maxillary central incisors using a conservative technique for the incision of the recipient site is presented, along with the 11-month follow-up from surgery. A supraperiosteal tunnel was performed for the insertion and stabilization of a connective tissue autograft.
