Flexible Tunnel Technique in Endo-Perio Lesion Surgery

The flexible tunnel technique involves four vertical incisions and one horizontal incision to mobilize a gingival flap, providing enhanced access for debridement and regenerative graft placement in deep endodontic-periodontal defects. Indicated for severe endo-perio lesions with extensive bone loss, it shows improved periodontal attachment and root coverage over a 2-year follow-up. Applicable in periodontal surgery.
