A Novel 3D Tunneling Surgical Technique (3DT) for the Treatment of Gingival Recessions with Reconstruction of the Deficient Interdental Papilla and Interproximal Attachment Regeneration: Case Series.

Background: Current concepts in periodontology emphasize an important distinguishing aspect of the interproximal attachment, assigning its major influential significance as a key diagnostic and prognostic factor. A complete regeneration of the interproximal clinical attachment has become a primary determinant of the periodontal success. Since mid - 20th century have been published numerous articles on root coverage procedures but mostly for non-proximal gingival recessions. When it comes to the interdental area, literature does not inspire the same level of confidence.

Objectives: This study is aimed to introduce an innovative 3D - Tunneling Surgical Technique for the gingival papilla reconstruction and supra-alveolar interproximal attachment regeneration.

Materials and methods: The technique is described step by step and shown on three selected clinical cases of multiple bilateral adjacent gingival recessions type 2 and 3 in the lower anterior area with follow - up results of up to 6.5 years.

Results: A total of 18 proximal, mid-buccal and mid-lingual recessions were treated simultaneously. Mean root coverage up to 88.9% has been achieved in the proximal area.

Conclusion: Within its limits, this study demonstrates a possibility of treating gingival recessions with deficient papilla in the mandibular anterior region, achieving a significant clinical improvement with the long-term stability.
