Summary
The tunnel technique (TUN) effectively treats gingival recessions (GRs) by preserving papilla integrity. A new classification system aids in managing surgical complexity based on site anatomy.
Area of Science:
- Periodontology
- Oral Surgery
Background:
- The tunnel technique (TUN) is a surgical approach for treating gingival recessions (GRs).
- It involves creating envelope flaps to facilitate the insertion of grafts or biomaterials, preserving the interdental papilla.
Purpose of the Study:
- To provide a comprehensive overview of tunneling flap procedures for soft tissue coverage in GR treatment.
- To introduce a classification system for GR site anatomy to assess surgical complexity.
Main Methods:
- A review of tunneling flap procedures for gingival recession treatment.
- Development of a classification system based on soft and hard tissue anatomy at GR sites.
Main Results:
- The tunnel technique demonstrates high effectiveness in treating single and multiple gingival recessions.
- A novel clinical classification system is proposed, categorizing complexity by factors like mucogingival junction proximity, bone morphotype, and mucosal thickness.
Conclusions:
- The tunnel technique is highly effective for treating gingival recessions, though outcomes can be influenced by anatomical variations and surgeon expertise.
- The proposed classification system aims to help clinicians identify and manage surgical complexity in tunneling procedures for optimal wound healing and root coverage stability.
