Long-term outcomes of coronally advanced tunnel flap (CATF) and the envelope flap (MCAF) plus subepithelial connective tissue graft (SCTG) in the treatment of multiple recession-type defects: A 6-year retrospective analysis

This study evaluated the 6-year results of the subepithelial connective tissue graft (SCTG) plus envelope-type flap (modified coronally advanced flap; mCAF) or coronally advanced tunnel flap (CATF) in the treatment of multiple recessions. Thirty-six patients with at least two adjacent recessions were included. Complete root coverage (CRC), mean root coverage (MRC), and keratinized tissue (KT) width were recorded over the course of the study. Both groups presented similar CRC, MRC, and KT outcomes between the 1-year and 6-year follow-ups. MRC decreased from 96.90% to 94.16% for mCAF, and from 89.56% to 83.10% for CATF. Both surgical techniques were similarly efficient in treating multiple recessions in the short term, and in maintaining the stability of therapy in the medium and long term.
