Root coverage is the goal of periodontal plastic surgery when treating gingival recessions. The aim of the present study was to evaluate the clinical results 1 year after treatment with an envelope connective tissue graft technique for single recessions. Forty consecutive patients with single recessions were treated. At baseline and 1 year after surgery, recession, probing pocket depth, clinical attachment level, and keratinized tissue height were recorded. After 1 year, the mean differences in recession (3.12 ± 0.90 mm), clinical attachment level (3.92 ± 1.00 mm), keratinized tissue height (3.75 ± 0.95 mm), and probing pocket depth (0.50 ± 0.64 mm) were statistically significant. Mean root coverage was 95.54% ± 11.43%; 85% of the treated cases achieved complete root coverage. The envelope connective tissue graft technique showed high predictability in the treatment of single recessions.
