This retrospective study aimed to compare the effectiveness of an equine collagen matrix (ECM) with that of a subepithelial connective tissue graft (CTG) in patients affected by Class I and II gingival recessions treated with a coronally advanced flap (CAF) technique.
Records of 50 consecutive patients were analyzed. Recession depth, probing depth, keratinized tissue width, and percentage of root coverage had been recorded at baseline and at the 1-year follow-up. The number of patients that achieved complete root coverage was also assessed. According to the investigated parameters, ECM and CTG provide similar results when used in association with a CAF technique.
