  • ABSTRACT: The aim of this case series was to evaluate the effectiveness of the collagen matrix (CM) associated with platelet-rich fibrin (PRF) in the treatment of gingival recession (GR). Six non-smoker patients that presented at least one site with single GR in the maxilla were included. Four GR were treated with conventional coronally advanced flap and six GR were treated with a modified coronally advanced tunnel technique. In both techniques, the PRF was immobilized above the CM. A reduction in the GR depth (2.00 mm (1.50-3.50) to 0.00 (0.00-0.00)) and pocket probing depth (1.25 mm (1.00-2.00) to 1.00 mm (1.00-1.62)) resulting in complete root coverage in all GR after 1 month. However, a displacement of the marginal gingival of 0.50 (0.00-1.00) associated with a gingival thickness reduction (1.35 (0.90-1.82)) was observed after 12 months. The association of the CM and PRF was effective in the GR coverage.
