Tunnel vs coronally advanced flap with connective tissue graft for maxillary anterior gingival recessions. Esthetic outcomes of a 2- to 14-year patient-centered cross-sectional study.

Greater keratinized tissue can be achieved with the TUN approach. Residual recessions of ≤ 0.5 mm after 2 years were absent for RT1 and unlikely for RT2 defects and did not significantly influence the overall VAS or RES esthetic scores.
