The "Modified Tunnel" technique is a method of esthetic connective tissue grafting that protects the interdental papillae. First published in 1999, this lateral tunnel approach uses vertical incisions on both sides of the treatment area. These vertical incisions facilitate placement and positioning of the graft over the root surfaces without the need to disturb the interdental papillae. This technique is very useful in esthetic areas and those that involve several teeth. An acellular dermal connective tissue allograft is an excellent choice of graft material to use with this technique.
