Treatment of Multiple Adjacent Miller Class III Gingival Recessions with a Modified Tunnel Technique: A Case Series

Modified coronally advanced tunnel (MCAT) technique with connective tissue graft (CTG) was used in treating multiple adjacent Miller Class III gingival recessions in nine patients. Clinical evaluations were recorded at baseline and 12 months after surgery. The results showed that 50% of complete root coverage and 78% of mean root coverage were attained 1 year after surgery and interdental space fill was 73% at 12 months. The study demonstrated that CTG using the MCAT technique may be an efficient way to treat multiple adjacent Miller Class III gingival recessions, especially when aiming for interdental space fill. Success, however, seems to be related to the amount of tissue present initially.
