Split-Mouth Comparison of Coronally Advanced Flap with Connective Tissue Graft or Collagen Matrix for Treatment of Isolated Gingival Recessions.

Collagen matrices (CMs) could be used instead of connective tissue grafts (CTGs) for treatment of gingival recession (GR). The authors aimed to compare clinical outcomes after treatment of isolated GR affecting both maxillary canines of 10 patients (n = 10) with CM (OsteoBiol Derma) or CTG in conjunction with coronally advanced flap. After 12 months, CM and CTG showed complete correction in 7/10 and 10/10 of sites, respectfully, and percentage of root coverage was 85% ± 24% and 100%, respectively. For treatment of isolated GR, CM is a viable alternative to CTG.
