CLINICAL EVALUATION OF THE USE OF DYNAMATRIX PLUS ® MEMBRANE VERSUS SUBEPITHELIAL CONNECTIVE TISSUE GRAFT WITH CORONALLY POSITIONED FLAP IN THE TREATMENT OF GINGIVAL RECESSION

Abstract

Background: DynaMatrix Plus is a porcine resorbable membrane that has only intact extracellular matrix (ECM). Unlike the other dermal matrices, it does not only act as a scaffold but is claimed to promote wound healing, stimulate vascularization, help in cell proliferation and migration. The aim of the study was to evaluate the efficiency of using this membrane in treating gingival recession. Method: 14 patients with 22 gingival recession defects were selected, each had at least one buccal gingival recession miller class I or II. The patients were divided into two groups: Test group (11 defects) received DynaMatrix Plus membrane in conjunction to coronally positioned flap and the control group II (11 defects) received subepithelial connective tissue graft (SCTG) with coronally positioned flap. Clinical measurments as gingival index, clinical attachment level, amount of root coverage, thickness and width of keratinized tissue were recorded before surgery, 3, 6 and 12 months postsurgically, in addition to root coverage esthetic score (RES) at 12 months postsurgically. Results: Both treatment modalities resulted in significant improvements in all clinical parameters. The results of the present study showed that there was no statistically significant difference between the two groups in all clinical parameters in all study intervals except for the width of keratinized tissue and thickness of gingiva after 6 and 12 months respectively in favor of the SCTG group. Conclusions: The present study showed that although SCTG is considered the gold standard graft for root coverage and is somehow superior to DynaMatrix Plus membrane, but DynaMatrix Plus can be a good alternative to SCTG in treatment of gingival recession.
