Study Arms:
- CAF plus connective tissue graft (Type: ACTIVE_COMPARATOR): CAF treatment was performed by starting with two divergent releasing incisions lateral to the recessed area. A sulcular incision was made to unite the releasing incisions and the flap was raised beyond the mucogingival junction (MGJ) in split-full-split thickness. The connective tissue graft was removed from the palate according to Bruno technique (1994) and sutured in position. Sling sutures were placed to stabilize the flap in a coronal position 2 mm above the CEJ, followed by interrupted sutures to close the releasing incisions.
- Tunnel plus connective tissue graft (Type: EXPERIMENTAL): The tunnel flap was performed according to Zuhr et al., 2007. Following initial sulcular incisions, spit thickness flap was prepared using specific tunneling knives beyond the mucogingival junction and until flap gain mobility. The flap was laterally extended to adjacent papillae that were carefully detached by means of a full-thickness preparation. The connective tissue graft was insert into the tunnel. Sling sutures were performed involving the flap and graft to coronally cover 2 mm above the CEJ.

Based on this trial design, predict the completion outcome and termination type (if applicable).
