Tunnel soft tissue augmentation using a free connective tissue graft in the area of dental implants is a popular technique in modern clinical dentistry. This technique is aimed at preventing soft tissue loss in the postoperative period, especially in clinical settings complicated by severe localized periodontitis. Given the high risk of inflammatory and recurrent processes in severe forms of periodontitis, the rationale for using this technique is particularly clinically significant. Materials and methods. Forty patients with chronic, severe localized periodontitis in the area of the central teeth of the maxilla were examined and operated on. In Group I, 20 patients underwent extraction and simultaneous dental implantation, as well as tunnel soft tissue augmentation using a free connective tissue graft (FCT). Patients in the control group II (n=20) underwent tooth extraction and immediate dental implantation without soft tissue grafting. Soft tissue loss in the implant area was assessed after 12 months. Results. In Group I, the average soft tissue loss was 1.0 mm, which was significantly less than 2.1 mm in the control group (p<0.01). Conclusion. Tunnel soft tissue grafting using FCT during extraction and immediate dental implantation in the anterior region of the maxillary dentition contributes to a favorable prognosis and prevents postoperative soft tissue loss around dental implants. © 2025, Clinical Dentistry LLC.
