A healthy 26-year-old woman was referred for evaluation and treatment of her failing maxillary right central incisor (tooth 11). She reportedly traumatized the tooth at about age 9 and subsequently had repeated conventional and surgical endodontic procedures and fixed restorations. Despite these procedures, she had recurrent fistulas in the apical mucosa and a mid-facial pocket of 7 mm with suppuration. All other sites on the tooth probed 3 mm without inflammation. She presented with a medium biotype with triangularlyshaped teeth and a moderately high smile line, showing all of her papillas and a few millimeters of marginal gingiva in a full smile.Ceramic veneers were present on teeth 12, 21, and 22, and they were known to be somewhat bulky, eventually requiring replacement. She had a strong desire to avoid additional tooth preparation and would not consider a fixed dental prosthesis to replace tooth 11.
