Abstract
Background: Gingival recession in the esthetic zone compromises appearance and root integrity. The tunnel technique combined with subepithelial connective tissue graft (CTG) offers a minimally invasive and predictable solution, maintaining papillary integrity and enhancing soft tissue thickness.
Case Description: A 40-year-old male presented with dentinal hypersensitivity in the maxillary anterior region. RT1(Recession type 1) affected teeth 11, 12, 21, and 22. Cervical abrasions previously restored with glass ionomer cement were observed in teeth 11 and 21. Given adequate attached gingiva and traumatic brushing history, a pouch and tunnel technique with palatal CTG was performed. The procedure yielded excellent root coverage, increased gingival thickness, and reduced sensitivity.
Conclusion: The tunnel technique with CTG is effective in managing RT 1 gingival recession even in the presence of restorative materials. Its minimally invasive nature supports favorable esthetic and functional outcomes without compromising existing restorations.
