Abstract: Objective To evaluate the effect of modified Tunnel technique with connective tissue graft (CTG) in the treatment of multiple Miller Ⅲ gingival recessions. Methods A total of 40 teeth from 10 patients were included in this study. The gingival recessive depth (REC), keratinized gingival width (KGW), probing depth (PD), clinical attachment level (CAL) and the distance between the contact point and the tip of the papilla (DCP) were recorded at baseline and 6 months after root coverage surgery. The mean root coverage and complete root coverage were also calculated. Results Six months after surgery, REC decreased from (3.08±0.94) mm to (0.70±0.69) mm, and the KGW increased (0.25±0.49) mm, CAL and DCP were also significantly improved. The mean root coverage was 79.78% and the complete root coverage was 42.50%. Further analysis showed that mean root coverage and complete root coverage were not related to the teeth position or the number of adjacent teeth. Conclusion Modified Tunnel technique combined with CTG can access good clinical effect andmay be an effective method in the treatment of multiple Miller Ⅲ gingival recessions.
