Brief summary
Microsurgical coronally advanced tunnel procedures using subepithelial connective tissue grafts (sCTG) are predictable for healing of multiple adjacent type 1 and 2 gingival recessions (RT1 and RT2). In order to reduce patient morbidity and enhance periodontal wound healing with sCTG can be used. The aim of this study is to compare the results of the modified tunneling technique with subepithelial connective tissue graft in gingival recessions placed with the inner side towards the flap cover graft and the outer side towards the flap cover graft.

Interventions
PROCEDUREThe tunnel technique for root coverage with CTG with inner side of the graft
Tunnel technique for root coverage with a subepithelial connective tissue graft (CTG). A split-thickness mucogingival tunnel will be prepared without vertical releasing incisions. The CTG will be inserted into the tunnel and positioned so that the inner (deep) side of the graft faces the inner surface of the flap (standardized graft orientation). The graft will be stabilized with sutures, and the flap will be coronally advanced to completely cover the graft.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percent Change in Gingival Recession (Mean Root Coverage, MRC) | Baseline and 6 months after surgery | Mean root coverage (MRC) was calculated as the percent change in gingival recession height from baseline to 6 months using the formula: (GR0 - GR6) / GR0 × 100%. * GR-gingival recession height: distance between the cementoenamel junction (CEJ) and the gingival margin at the mid-buccal side * GR0- before surgery * GR6- 6 months after surgery |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| GR Change (Gingival Recession Height Change) GT Change (Gingival Thickness) KTW Change (Keratinized Tissue Width) | 6 months after surgery | The analyzed metrics were calculated as follows: GR change= GR0-GR6 (after 6 months); ) \[millimetre\] higher scores mean better outcome GT change = GT6-GT0 (after 6 months); \[millimetre\] higher scores mean better outcome KTW change = KTW6-KTW0 (after 6 months); \[millimetre\] higher scores mean better outcome * GR-gingival recession height: distance between the cementoenamel junction (CEJ) and the gingival margin at the mid-buccal side * GT- gingival thickness * KTW- distance between the gingival margin and the muco-gingival junction (MGJ) * 0- before surgery * 6- 6 months after surgery |
