Introduction: The main goal of periodontal plastic surgery is obtaining complete root coverage (CRC) and an optimal appearance. Aim: The aim of this study was to evaluate the effectiveness of a three-dimensional porcine collagen matrix (PCM) with coronally advanced flap (CAF) in treating of Miller type I and II gingival recession (GR). Materials and Methods: Twenty patients were enrolled in this study, presenting 40 Miller type I and II GR. Patients were randomized into test group (PCM + CAF) and control group [connective tissue graft (CTG + CAF)]. Clinical parameters such as recession depth (RD), probing depth, clinical attachment level (CAL), and width of keratinized gingiva (WKG) were evaluated at baseline and 12 months later. Root coverage percentage (RC%) and CRC were assessed at 12 months post surgically. Statistical analysis was performed using independent t-test for intergroup comparison. Statistical significance was set at 0.05. Results: The mean RD at 12 months was 0.20 mm for the test group and 0.12 mm for the control group, whereas the mean RC% was 94.22% for PCM + CAF and 96.48% for CTG + CAF. CRC was higher in CTG + CAF with 80%. CAL gain was 2.05 and 2.07 mm in the test and control sites, respectively. The gain of WKG was 1.35 and 1.30 mm in the test and control sites, respectively. Patient esthetic satisfaction at 12 months post surgically in both groups was equivalent. Conclusion: Within the limits of this study, using of PCM + CAF in treating GR is a successful and effective treatment option and could serve as an alternative to CTGs.
