Long term assessment of root coverage stability using connective tissue graft with or without an epithelial collar for gingival recession treatment. A 12‐year follow‐up from a randomized clinical trial

Abstract

CAF + CTG and CAF + ECTG were found equally efficacious in maintaining the levels of the gingival margin with a small amount of relapse over the period of 12 years while CAF-alone sites showed a greater gingival recession (GR) reoccurrence.
