ABSTRACT

Aim: The purpose of this paper is to present a case in which root coverage is performed on a type I lingual gingival recession using an acellular dermal matrix (Dermis).
Methods: Following corrective orthodontic treatment, a 28-year-old patient presented a 5-mm gingival recession in the lingual region of the lower-right central incisor, together with a 2-mm band of keratinized gingiva and 2-mm deep sulcus, resulting in hypersensitivity to cold. In the absence of a suitable palatal donor, we decided to use an acellular dermal matrix (Dermis) as an allogeneic graft to cover the aforementioned recession.
Results: A total of 80% root coverage was achieved, with 1 mm of postoperative gingival recession remaining; there was an increase in gingival biotype (in terms of thickness) and an increase in the height of the keratinized gingiva from 2 to 5 mm (a gain of 3 mm), 3 months after the surgery. These changes were still apparent upon examination one year after surgery.
Conclusion: The acellular dermal matrix is a surgical alternative in lingual root coverage that prevents discomfort and potential postoperative complications by taking a graft from connective palatal tissue. Up to 80% root coverage is achieved, along with an increase in the band of keratinized gingiva, the results remaining constant one year after surgery.
