Collagen matrix (Mucoderm) as an alternative for the treatment of gingival recessions

Abstract

_B_Background_b_ Coronally advanced flap plus connective tissue graft (CTG) is the gold standard therapy for root coverage. The bioabsorbable porcine collagen matrix (PCM) has been widely used in periodontal and mucogingival surgery as a substitute for CTG and has achieved similar results. The PCM has the advantage of availability overcoming the limitations of donor site in autograft. _B_Aim/Hypothesis_b_ The aim of this study is to investigate the use of PCM (Mucoderm) in root coverage procedures combined with extended coronally positioned flap (ECAF) in comparison to the CTG associated with the ECAF. _B_Material and Methods_b_ Sixteen adult patients, non‐smokers, presenting bilateral Class I or II Miller gingival recession were selected. Clinical parameters, probing depth, clinical attachment level, recession height and keratinized tissue height (KTH) and thickness (KTT) were recorded at baseline and 3 months after the surgical procedures by a blinded examiner. _B_Results_b_ The PCM)
