Porcine Collagen Matrices for the Treatment of Multiple Gingival Recessions: A Case Report With 4 Years Follow-Up

This case report aimed to evaluate the clinical performance of Mucoderm and Fibro-Gide collagen matrices (CMs) as alternatives to connective tissue graft (CTG) in the treatment of multiple gingival recessions (GRs).

A 37-year-old man, systemically healthy and a nonsmoker patient, with multiple bilateral GR (recession type 1 class [RT1] or Miller Class I) involving teeth 12-16 and 22-26 was surgically treated. Envelope type of coronally advanced flap (CAF) was used in teeth 14-16 and 23-26 associated with Fibro-Gide matrix on the right side and Mucoderm matrix on the left side.

Complete root coverage was observed in all GR after 60 days of postoperative, except for tooth 22. In the Fibro-Gide matrix-treated side, a greater increase in keratinized tissue (KT) volume was visually observed after 60 days. However, an apical displacement of approximately 0.50 mm of the marginal gingiva was observed in teeth 14, 15, 24-26 with 12 months, showing stability of the results after 4 years of follow-up. Moreover, no differences regarding KT volume and gingival color/texture were visually observed between both matrices after 5 years.

The Mucoderm and Fibro-Gide CMs demonstrated adequate clinical performance for GR coverage in this case report.
