Tunnel technique with connective tissue graft versus coronally advanced flap with enamel matrix derivative for root coverage: a RCT using 3D digital measuring methods. Part II. Volumetric studies on healing dynamics and gingival dimensions.

摘要: AIM: The aim of this randomized clinical trial (RCT) was to compare the performance tunnel technique with subepithelial connective tissue graft (TUN) versus a coronally advanced flap enamel matrix derivative (CAF) in treatment gingival recession defects. use innovative 3D digital measuring methods allowed study healing dynamics at (CT)-grafted sites and evaluate influence thickness root covering soft tissues on outcome surgical coverage. MATERIAL & METHODS: Twenty-four patients contributed total 47 Miller class I or II recessions for scientific evaluation. Precise models collected baseline follow-up examinations were optically scanned virtually superimposed evaluation measures including mean marginal (THK). Healing measured defined region interest CT-grafted where volume differences between time points calculated. RESULTS: At 12 months, reduction as well coverage significantly better treated TUN group (1.94 mm 98.4% respectively) compared non-augmented CAF (1.17 mm 71.8% statistical analysis revealed positive correlation THK (1.63 mm 0.91 mm CAF, p < 0.0001) both these variables. Soft following CT-grafting mainly accomplished after 6 months, around two-thirds augmented being maintained 12 months. CONCLUSIONS: resulted thicker gingiva outcomes CAF. Increased associated terms coverage.
