Peri-implant mucosal recessions can be a major esthetic problem in the anterior zone, whereas in the functional zone the coverage of exposed implants is not of primary significance, as methods to clean these structures are more important. In these situations free gingival grafts are often used to deepen the vestibule and increase the amount of attached keratinized mucosa. Complete coverage of mucosal recessions around dental implants is still a challenging procedure, but it seems that recessions up to 2 mm can be successfully grafted with subepithelial connective tissue grafts.
