Modified Tunnel Technique and Double-Layer Acellular Dermal Matrix to Treat Multiple Teeth and Implant: 3.5-Year...

Recession defects can affect both tooth and implant sites. The objective of connective tissue grafting is to correct recession defects and develop a soft-tissue architecture that is both stable and natural in appearance. By protecting the integrity of the interdental papillae, tunnel techniques are intended to maximize esthetic results. The use of an acellular dermal matrix (ADM) allows treatment of multiple adjacent recession defects without the need for a palatal donor site. The dental literature is scarce on the use of ADMs to treat recession affecting implant sites. The purpose of this article is to discuss and demonstrate the use of a modified tunnel technique and a double layer of an ADM in the treatment of recession defects affecting multiple teeth and an implant.
