Optimization of the tunneling technique in the treatment of gingival recessions

Introduction: gingival recession has presented significant aesthetic and functional challenges for patients, making it imperative to search for effective surgical techniques that improve periodontal results. Therefore, the present study has focused on optimizing the tunneling technique with a subepithelial connective tissue graft, through the implementation and evaluation of different clinical strategies that improve the results of surgery and patient safety. Method: the VIKOR method was used for multi-criteria decision making, which allowed the analysis of several strategies based on specific criteria related to the results of surgery and patient safety. Eight evaluation criteria were established and six strategies were rated in two aspects, one focused on satisfaction with the results and the other on patient safety and health. Results: the advanced training and clinical practice strategies and comprehensive periodontal health program were identified as the most effective, showing high scores in technical competence, patient satisfaction, adherence to the protocol, and reduction of complications. Conclusions: the tunneling technique with a graft of subepithelial connective tissue is effective for the treatment of gingival recessions. The success of this technique has critically depended on surgeon training, adherence to standardized protocols, and an integrated approach that has included patient education and rigorous follow-up. The objective and systematic evaluation of the proposed strategies allowed us to highlight the importance of a well-informed and managed clinical practice
