Novel Membrane for the Treatment of Multiple Gingival Recession Defects-RCT

Abstract

Objective Evaluation and comparison of Collagen Matrix Ossixreg Volumax and Subepithelial connective tissue graft SCTG in combination with modified coronally advanced flap MCAF in the treatment of Miller Class I and II multiple gingival recession defects MARDs.Methods Twelve patients presenting adjacent Miller Class I and II maxillary and mandibular gingival recession defects participated in this randomized controlled study. A total of sixty defects were received n 30 either Ossix Volumax collagen matrix VCMX and MCAF test group or MCAF and Subepithelial connective tissue graft control group n 30. Parameters like gingival recession depth gingival recession width probing depth clinical attachment level and keratinized tissue width were checked at baseline 6 weeks 3 months and at 6 months after treatment. P value lt0.05 was considered statistically significant.Results The percentage of complete root coverage was 80 for the test group and 60 for the control group. The percentage of mean recession coverage for the test group was 60 and the control group was 85. Adjacent gingival recession was successfully treated with MCAF and Ossixreg Volumax or with MCAF and SCTG. The use Ossixreg Volumax was more comfortable during the postoperative period.Conclusion We suggest the use of Ossixreg Volumax as a promising collage matrix for the treatment of MARDs.
