Treatment of gingival recession with a modified "tunnel" technique and an acellular dermal connective tissue allograft.

The treatment of gingival recession through the creation of a "tunnel" beneath the buccal mucosa allows coronal repositioning the soft tissue with predictable root coverage and aesthetics. Vertical incisions on either side of this tunnel preparation enable placement of a connective tissue graft within the tunnel. The use of an acellular dermal connective tissue allograft permits grafting of multiple sites without the need for a donor tissue surgical site or additional visits. This article demonstrates a modified tunnel technique and a case presentation that incorporates this procedure.
