The aim of this study was to present a periodontal plastic-surgery approach to treat gingival recessions and correct lower incisor mucogingival conditions and deformities. Isolated deep gingival recessions (≥ 3 mm) in the lower incisors (n=24 teeth) were treated: 66.6% of sites were recession type 2/3, and 58.3% of teeth were malpositioned. Recessions were treated using free mucogingival grafts (FMG) harvested from the buccal aspect of donor teeth with altered passive eruption or healthy periodontal support, with <3 mm between the cementum-enamel junction and buccal alveolar crest. Clinical parameters [gingival recession, clinical attachment level, interproximal papilla tip location, keratinized tissue, vestibule depth] and root coverage esthetic score were evaluated at 9 months. FMG significantly reduced gingival recession (p<0.001) and increased keratinized tissue (p<0.001) without loss of vestibule depth (p>0.05). Mean root coverage was 94.37±10.60%, mean residual gingival recession 0.08±0.65 mm and mean root coverage esthetic score 8.9±1.24. Recession types 2/ 3 showed significant interproximal clinical attachment gain (p<0.05). The interproximal papilla was significantly augmented at sites with papilla loss (p<0.001). No donor-site clinical attachment loss (p=0.346) was detected. Our results suggest FMG is a promising approach to root coverage in recession types 1, 2 and 3, correcting mucogingival conditions and deformities, and reconstructing the interproximal papilla.
