Selection of Tactics of Modern Restorative Surgery for Chronic Periodontal Diseases

Relevance. Periodontitis accounts for up to 90 % of all periodontal disease in adults worldwide and 82 % in Russia. Effective treatment of chronic periodontal disease is a pressing issue. The aim of this study is to substantiate the choice of surgical restorative approaches for chronic periodontal disease using tissue regeneration agents. Patients and Methods. From 2019 to 2025, 74 patients aged 25 to 72 years with chronic generalized periodontitis and tooth mobility grades I-II-III underwent surgical treatment using the proprietary technique of A.I. Musienko and A.A. Musienko. This involves the formation and mobilization of a new type of mucoperiosteal flap without dissecting its distal portion to maintain trophism and placed tension-free until the defect is completely covered. In addition, patients in the observation group (n = 46) received bone grafting material under the flap on the exposed teeth before wound suturing and covered with a membrane of concentrated autogenous plasma and platelets with a high fibrin content (Fibrine Riche en Plaquettes – FRP). Result. The author's technique and the use of FRP-guided tissue regeneration products demonstrated greater clinical efficacy and statistically significantly better long-term results in terms of oral hygiene, periodontal health (Silness-Loe and PMA indices), and stability of bone mineral density gains compared to the comparison technique. Conclusion. The obtained results substantiate the possibility of recommending this method when choosing a surgical approach for chronic generalized periodontitis with grades I-II-III tooth mobility for practical healthcare.
