Surgery was performed with a complete excision of the lesion together with the surrounding healthy tissue up to the bone. To guide the healing of the anterior esthetic framework and the excised tissues, a porcine collagen matrix as an alternative to connective tissue graft was used. After an 18-month follow-up, the lesion had not recurred and keratinized gingiva had formed around the area.
