Summary

Recent plastic procedures have provided satisfactory results in the treatment of gingival recession but there is, presently, a greater need for procedure that cause less surgical morbidity as also provide improved results. In this study we propose a novel vertical tunnel technique as a minimally invasive approach (Vertical Y-shaped Tunnel Approach) and evaluate clinical results in comparison to CAMT, both using CTG. The novel technique allows stability of the graft, maximum coronal vascularity and minimum soft tissue reflection.

Detailed description

The tunnel technique is an approach that optimizes esthetics and predictability because of its ability to avoid releasing critical papillae and maintaining a high level of vascularity at the surgical site to support the grafts. The tunnel technique has a minimally invasive nature since the interdental papillae are left intact and vertical incisions are not performed which results in better esthetics. This technique entailed the placement of a connective tissue graft in the tunnel. Complete graft coverage is not mandatory as long as the graft dimensions are sufficient to ensure its survival. Avoiding detachment of the highly fragile interdental soft tissue can minimize the risk of losing papilla height in critical esthetic areas, avoid scar formation, maximize the papillary and lateral blood supply to the underlying graft and better stabilize the graft for optimal wound healing Recent plastic procedures have provided satisfactory results in the treatment of gingival recession but there is, presently, a greater need for procedure that cause less surgical morbidity as also provide improved results. In this study we propose a novel vertical tunnel technique as a minimally invasive approach (Vertical Y-shaped Tunnel Approach) and evaluate clinical results in comparison to CAMT, both using CTG. The novel technique allows stability of the graft, maximum coronal vascularity and minimum soft tissue reflection.

Conditions

• Gingival Recession

Interventions

Type	Name	Description
PROCEDURE	Y shaped Tunnel with Connective tissue graft	Sulcular incision followed by Micro-periosteal elevator will be used to elevate vertical full thickness tunnel starting coronally from the gingival sulcus and directed apically. CTG will be prepared and inserted into the coronal tunnel aperture using blunt instrument to facilitate intrusion of graft into tunnel. CTG insurted into the tunnel up to the apical level leaving a coronal part to completely cover the recession defect. Finally single interrupted suture will be used to secure the coronal exposed part of the CTG followed by sling suture fixation of the gingival flap with that of CTG. The donor CTG will be stabilized to the underlying connective tissue interproximally using 5.0 sutures.
