The aim of the study was to evaluate the efficacy of mucoderm® for recession coverage in comparison to the autologous soft tissue transplant using a split-mouth design.

Twenty patients with multiple adjacent Miller Class I recession type defects were treated using the modified coronally advanced tunnel technique in conjunction with either mucoderm® (test group) or a connective tissue graft (control group) harvested from the palate. Clinical outcomes were compared 6 and 12 months post-operative.

– All clinical parameters improved significantly compared to baseline, with no statistically significant differences between test and control group 6 and 12 months post-operative
– Mean root coverage change from 6 to 12 months was statistically significant between the groups in favor of the control group
– Complete root coverage per recession was 46.8% and 51.9% in the test and control group respectively
– Complete root coverage per patient was 15% and 30% in the test and control group respectively
– Healing index scores were statistically significant better for the test group at the 1st , 2nd and 3rd week post-operative

Based on the achieved degree of root coverage, gain of gingival thickness and the good aesthetic outcomes, the authors concluded that mucoderm® is a valid alternative to the autologous connective tissue graft for the coverage of Miller Class I recessions.
