Subepithelial Connective Tissue Graft in Combination with a Tunnel Technique for the Treatment of Miller Class II and III Gingival Recessions in Mandibular Incisors: Clinical and Esthetic Results

There is limited evidence regarding the effect of the subepithelial connective tissue graft (SCTG) on root coverage in the mandibular anterior region. A sample of 15 Miller Class II and III recessions were treated in 15 patients using a SCTG with a tunnel technique. After a mean follow-up of 20.53 months, the mean percentage of root coverage was 83.25% for all treated recessions. Furthermore, a statistically significant increase of keratinized tissue was observed at the end of the evaluation period (2.66 mm; P = .001). The combination of tunnel technique and SCTG should be considered a treatment option to obtain root coverage in mandibular incisors with Class II and III recession defects.
