A Surgical Approach to Root Coverage and Correction of Mucogingival Conditions and Deformities in Mandibular Incisors with Isolated Gingival Recession: Free Mucogingival Graft. A Pilot Prospective Cohort Study.

The aim of this study was to present a periodontal plastic surgery approach to treat gingival recessions (GRs) and correct mandibular incisor mucogingival conditions and deformities. Isolated deep GRs (≥ 3 mm) in the mandibular incisors (n = 24 teeth) were treated: 66.6% of sites were recession types 2 or 3, and 58.3% of teeth were malpositioned. Recessions were treated using free mucogingival grafts (FMGs) harvested from the buccal aspect of donor teeth with altered passive eruption or healthy periodontal support, with < 3 mm between the cementoenamel junction and the buccal alveolar crest. Clinical parameters (GR, clinical attachment level, interproximal papilla tip location, keratinized tissue, vestibule depth) and root coverage esthetic score were evaluated at 9 months. FMG significantly reduced GR (P < .001) and increased keratinized tissue (P < .001) without loss of vestibule depth (P > .05). Mean root coverage was 94.37% ± 10.60%, mean residual GR was 0.08 ± 0.65 mm, and the mean root coverage esthetic score was 8.9 ± 1.24. Recession types 2/3 showed significant interproximal clinical attachment gain (P < .05). The interproximal papilla was significantly augmented at sites with papilla loss (P < .001). No clinical attachment loss (P = .346) was detected at donor sites. These results suggest that FMG is a promising root coverage approach for recession types 1, 2, and 3, correcting mucogingival conditions and deformities and reconstructing the interproximal papilla.
