Covering of gingival recessions with a modified microsurgical tunnel technique: case report.

Author information

Institute for Periodontology and Implantology, Munich, Germany.


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.
