The aim of the present case series was to evaluate the outcomes of the modified coronally advanced tunnel technique (MCAT) using the width of keratinized tissue (KTW) as an indicator to apply the connective tissue graft (CTG) specifically. Seven patients requiring treatment for the presence of multiple gingival RT1 recession defects in the maxilla were enrolled in the study. A total of 36 recessions were treated with MCAT, and the CTG was applied in 16 sites presenting < 2 mm of KTW at baseline. The mean root coverage from baseline to 1 year postsurgery was 90% for the sites treated with MCAT alone and 93.7% for those treated with MCAT+CTG. The increase of KTW was higher in the sites treated with CTG than in the sites treated without it. Within the limitations of the present case series, it can be concluded that the proposed surgical technique is extremely effective in gaining root coverage and reducing the amount of connective tissue harvested from the donor site.
