Comparing Two Different Tunneling Technique for Gingival Recession Treatment Using Two Different Matertial

Summary

The goal of this clinical trial is to compare two different tunneling surgical technique in treatment of gingival recession using two different materials.

Participants will be divided into four groups according to the treatments they'll be given.

Conditions

• Gingival Recession, Localized

Interventions

PROCEDURE

The Laterally Closed Tunnel Technique with SCTG

Local anesthesia using 4% articane with 1:100.000 epinephrine was applied.• Then specially designed tunneling instruments \[devmed\] were used through the sulcular incision to create a pouch. A microsurgical blade was used at the inner surface of the pouch till sufficient tissue release was achieved. Tissue forceps was used to approximate the mesial and distal margin of the gingiva at the pouch margin. After harvesting the graft, it was placed at the prepared pouch after root surface biomodification using EDTA gel 24% for 2 minutes and copious rinsing with saline solution. 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.

DRUG

The Laterally Closed Tunnel Technique with collagen matrix mucograft

PROCEDURE

Modified Coronally Advanced Tunnel Technique with SCTG.

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.
