Aim: The aim of the study was to evaluate the effectiveness of the VISTA technique with subepithelial connective tissue graft for management of multiple Miller class III gingival recessions compared to the coronally advanced flap with subepithelial connective tissue graft. Materials and methods: The study included 20 patients with 75 recession defects and were randomly and equally assigned to either VISTA or CAF groups. Both groups received de-epithelialized subepithelial connective tissue graft (SCTG). Clinical evaluation of the results was performed 3 and 6 months after surgery. The amount of root coverage along with recession depth and width, keratinized tissue width (KTW), gingival thickness, pocket depth (PPD) and clinical attachment loss (CAL) were measured. Moreover, patient satisfaction was evaluated using root coverage esthetic score (RES). Results: After 6 months, there was no statistically significant difference among the study groups in regards to the amount of root coverage. However, the mean amount of root coverage was higher in the VISTA group and achieved complete root coverage (CRC) in 15.9% of the treated defects unlike the CAF group who failed to achieve CRC. The root coverage esthetic score (RES) in both groups showed a statistically significant improvement of patients{u2019} esthetics. There was a statistically significant difference between RES of VISTA (8.13) and CAF (6.11) in favor of the test group after 6 months. Conclusions: VISTA technique and CAF, both when combined with SCTG, can be reliable in reduction of Rec depth of multiple class III gingival recessions. However, the esthetic result and the postoperative satisfaction of the VISTA technique are significantly higher than those of the CAF.
