title: Surgical Treatment of a Peripheral Ossifying Fibroma and Reconstruction with a Porcine Collagen Matrix: A Case Report.
abstract: A 35-year-old woman was referred to the Department of Oral Medicine and Orofacial Surgery after several recurrences of an ossifying fibroma (OF) that affected the free and attached gingiva of the maxillary right central incisor. 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.
