Summary

This study will follow adults who have gum recession on the tongue side of the lower teeth. Participants will receive a gum surgery called the Modified Coronally Advanced Tunnel technique with a connective tissue graft taken from the roof of the mouth. The study will include 20 participants and will follow them for up to 24 months after surgery. The main outcome is how much of the exposed root is covered 6 months after surgery. The study will also measure gum thickness, gum width, tooth sensitivity, healing, patient comfort, satisfaction, and three-dimensional soft tissue changes using intraoral scans.

Conditions

  • Gingival Recession
  • Mucogingival Deformity - Insufficient Keratinized Tissue

Interventions

PROCEDURE

Modified Coronally Advanced Tunnel with Connective Tissue Graft

The procedure consists of lingual tunnel preparation without vertical releasing incisions, followed by placement of a deepithelialized connective tissue graft harvested from the palate. Root surface conditioning may be performed with EDTA gel before graft placement. The graft is positioned to cover the exposed root surface, and the lingual flap is advanced coronally and secured with sutures to achieve stable, tension-free coverage.
