A 37-year-old female patient reported to us expressing concern over the mobility of her teeth, the presence of a recurrent fistula, and overall displeasure with the height of her gingival smile line. Upon clinical examination, it was determined that the maxillary incisors (i.e., teeth numbers 7, 8, 9, and 10) were compromised and that horizontal bone resorption had occurred as a result of aggressive periodontitis.
