Recent advances in periodontal plastic surgery have encouraged reassessment of the envelope technique and its modified version, the tunnel technique, for root coverage. This article describes alterations in the technique-sensitive tunnel approach, which include an undermining split flap preparation of the buccal tissues with newly developed instruments to minimize trauma and ensure a better blood supply for the connective tissue graft. The use of a microsurgical concept, including microsurgical blades and suture material, improves wound healing and establishes a better esthetic result. Because these modifications simplify the tunnel approach, the spectrum of indications for the tunnel technique may be expanded and a broader application achieved.
