Laterally Closed Tunnel VS Tunneling Technique in Recession Type 2

Overview

This study aims to assess the effect of tunneling technique with subepithelial connective tissue graft versus tunneling technique with laterally closed tunnel in treatment of recession type 2 defect.Few randomized clinical trial has been involved with recession type 2 defects treated with tunneling technique and coronal advanced flap.

Tunneling with subepithelial connective tissue graft: At the recipient site (recession defect): After scaling and root planning. A sulcular incision is made through the gingival margin and extends post the mucogingival line leaving the interdental papilla intact. At donor site (palate): A connective tissue graft is harvested from the palate after administration of local anesthesia using a partial thickness flap which will be raised with single incision. Then the graft is placed and secured in the recipient site using suture. The flap is displaced to be in a coronal position using a suture. Tunneling technique with the laterally closed tunnel): After local anesthesia, root planing of the exposed root surface will be performed. An intrasulcular incisions will be made creating a tunnel extending to the mucogingival line and mesial and distal recession defects while keeping the interdental papilla intact as well as not perforating the flap. * Donor SCTG Subsequently, a palatal SCTG will be harvested by means of the single incision technique with immediate closure of the donor site. * Recipient site; Using either single or mattress sutures, the SCTG will be pulled and fixed mesially and distally at the inner aspect of the pouch. The graft will be adapted to the CEJ by means of a sling suture. Finally, the margins of the pouch will be pulled together over the graft and sutured with interrupted sutures to accomplish tension-free complete or partial coverage of the graft as well as the denuded root surface.
