A Novel Vertical Y-shaped Tunnel Approach Versus Modified Coronally Advanced Tunnel Technique, for The Treatment of Miller Class I Gingival Recession

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.
