Minimally invasive treatment of gingival recession by vestibular incision subperiosteal tunnel access technique with collagen membrane and advanced platelet-rich fibrin: A 6-month comparative clinical study

Aim: The study aimed to assess the minimally invasive Vestibular Incision Subperiosteal Tunnel Access (VISTA) technique for treatment of Millers Class I or Class II buccal gingival recession defects and to compare the effectiveness of a bioresorbable collagen membrane or advanced platelet rich fibrin (A-PRF). Methods and Material: 20 sites with Millers Class I or II gingival recession were recruited and allocated into 2 groups with 10 sites each. Group 1: VISTA with A-PRF, Group 2: VISTA with with bioresorbable collagen membrane (Healiguide)®. Standardized Clinical Parameters: Plaque Index (PI), Gingival Index (GI), Clinical attachment level (CAL )Pocket Probing Depth (PPD) Recession Height (RH ) and width of keratinized gingiva (WKG) were measured at baseline 3 months and 6 months. Results: Both groups showed significant improvement in clinical parameters. However reduction in recession height and mean root coverage percentage was greater in A-PRF group after 6 months. Conclusions: VISTA with both A-PRF and Healiguide showed good clinical outcomes but better results were obtained when A-PRF was used.
