Mucoderm or Connective Tissue Graft for Treatment of Gingival Recessions

Clinical Comparison Between the Use of a Connective Tissue Graft or a Porcine Collagen Matrix (Mucoderm) for Treatment of Gingival Recessions Type 1: a Randomized Controlled Clinical Study.

Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (CM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The CM has the advantage of no need of a second surgical area and availability overcoming the limitations of donor site in autograft.

The aim of this study is to investigate the use of Mucoderm® in root coverage procedures combined with extended coronally positioned flap (ECAF), test group (TG), in comparison to the connective tissue graft associated with the ECAF, control group (CG).
