Limited evidence is available regarding the effect of the subepithelial connective tissue graft (SCTG) on root coverage in the mandibular anterior region. A technique is described using an SCTG with a coronally advanced flap (CAF) for the treatment of Miller Class II and III gingival recessions in mandibular central incisors. Fourteen Miller Class II and III recessions were treated in 10 patients using an SCTG with a CAF. After a mean follow-up of 11.7 months, 90.22% ± 12.36% root coverage was achieved. There were no statistically significant differences in root coverage for Miller Class II and III recession defects. Complete root coverage was achieved at five (71.42%) Miller Class II sites compared with three (42.85%) Class III defects. These results suggest that the combination of an SCTG and CAF is an effective technique to obtain root coverage in mandibular incisors with Class II and III recession defects, with excellent patient satisfaction regarding the esthetic appearance of the treated teeth.
