Subepithelial connective tissue graft (SCTG) is considered gold standard for root coverage treatment. However, it is associated with postoperative morbidity, limited amount of donor tissue and longer surgical time. Thus, the search for a tissue substitute for SCTG is increasing. Currently, one of the possible autogenous soft tissue substitutes found in the market is the Mucograft® xenogeneic matrix (MG). The results with the use of MC are very promising, both for root coverage as well as for gain of keratinized tissue. The present study consists of a parallel randomized clinical trial with the objective of comparing SCTG (control group) and MG (test group) in the treatment of Miller's class I and II gingival recessions, multiple in aesthetic areas (upper central incisors, Lateral and canine).
