Study: NCT06065774

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Modified Coronally Advanced Tunnel Technique with SCTG.
Description: Supraperiosteal incisions was extended to the mucosal level beyond the MGJ to allow sufficient tissue mobility and release.~The tunnel was extended in all directions around the recession defect to create a sufficient pouch for connective tissue graft stabilization.~The interdental papilla tunneling adjacent to the defect was a critical step for technique success.~Then perfect root planning was performed at the denuded root surface to remove the necrotic cementum at the accessible recession defect.~Subsequently palatal anesthesia was given to harvest palatal SCTG using deepitheliailized free gingival graft (FGG) technique.~SCTG was pulled using single or mattress sutures and the graft was fixed mesial and distal at the inner part of the pouch using resorbable suture material \[Vicryl suture\], then the graft was sutured around the neck of the CEJ by sling suture 6/0 polypropylene.
