Relevance. Gum recession is a pathology often encountered both in Russia and worldwide. Modern surgical methods allow for the complete elimination of recession signs when adequately choosing strategy, tactics, methodology and surgical treatment protocol; for complication prevention and stable long-term outcome. Autograft and allogeneic dura mater as a grafting material for creating/increasing the volume of the attached gingiva in recession treatment have comparable results in all clinical indications. The reason for result stability and the absence of relapse is poorly studied; the data are scarce and do not give a full understanding. In the scientific literature, we did not encounter histological tissue composition analysis in the graft placement area. In recession coverage, the graft is partially placed subperiosteally (in the tooth root area) and partially in the thickness of the soft tissues of the gum. Purpose. The study aimed to determine the histological composition of tissues in the dura mater placement area, to compare with the control group without a graft, and to assess follow-up changes in the graft and surrounding tissue reaction as a result of cellular-level surgery.Material and methods. A laboratory histomorphological examination involved 60 laboratory rats. All underwent surgery adequate to gum recession surgical treatment technique: the control group had no graft, and the study group had allogeneic dura mater. The samples were collected on the 3rd, 7th, 14th, 28th, 90th and 107th days after surgery.Results. In all cases, the tissue complex regenerated, and the reaction to the operation was the same. The plastic material replacement was at the same period. Bone tissue replaced subperiosteally placed graft, connective tissue intragingivally. Gingival biotype thickening was considerably due to the surgical trauma, less – from the graft material. Allogeneic dura mater stimulated earlier ossification.Conclusion. In all cases, the use of grafting material for surgical gum recession coverage is justified if placed subperiosteally, forming a full-thickness mucoperiosteal flap surgically (with a scalpel) to preserve the cambium periosteum on the flap. Bone volume and buccal cortical plate reconstruction/ regeneration support soft tissues of the newly formed ligament of the tooth and prevent recurrent recession formation. The formation of bone and connective tissues in the dura mater placement area determines the result stability of gingival recession surgical treatment and a long-term favourable prognosis without complications and relapse.

Relevance. The attached gum is a part of the periodontal tissue complex, attached tightly to the periosteum by connective tissue fibers. It protects the tooth or implant from mechanical injury of any etiology. Its absence or lack negatively affects the safety of teeth and, especially, implants. Due to the widespread development of implantological treatment, the prevalence of problems in the peri-implant area is very high. The basis for the treatment of peri-implantitis and its prevention is the creation of an optimal volume (width) of the attached gum. Due to the large number of different personal parameters and individual indicators that are important in assessing the status of a patient with peri-implant pathology in different clinical cases, treatment methods cannot be systematized at present. Today, the approach to the choice of strategy, tactics and specific methods of treatment of peri-implant pathologies is highly personalized. The aim of the study is to develop an algorithm for the application of periodontal tissue management methods for the surgical treatment of patients with peri-implant pathology. Materials and methods. The study presents and analyzes in detail a clinical case of augmentation of the attached gum in the area of implants by tunnel technique using an autograft. Results. The volume of the attached gum in the area of all operated implants, as well as in the area of adjacent teeth adequate to the required volume of peri-implant tissues, was obtained, the result was evaluated by measurable and visualized indicators. Conclusion. The tunnel technique using a free gingival deepithelized autograft allows you to create the necessary volume of attached gums in the peri-implant area, to form high quality soft tissues of the gum; it is the method of first choice due to low invasiveness, and fully meets the requirements of a personalized approach.

Introduction. Gingival recession is a highly relevant and common dental pathology. The prevalence of recession ranges from 45,5 to 99,3 % in people of different ages, with the risk of gingival recession increasing with age. The true etiology of gingival recession, its components and the degree of their influence, jointly or separately; the influence of the environment and lifestyle on the development of pathology are poorly understood. In the literature, for example, there is no classification of etiological factors according to the degree of their influence as triggers of gingival recession. It is of scientific interest to study the causes of gingival recession, their systematisation and assessment of the degree of influence of each factor separately and together.The aim of the study is to develop a classification system of etiological factors taking into account their significance and degree of influence on the formation of gingival recessions.Materials and methods. Analysis of scientific literature, methods of classification and structuring; methods of decomposition, integration and determination of cause-and-effect relationships.Results. A model of classification of factors of the etiology of gingival recessions was proposed, elements of the structure of etiological factors of gingival recessions were determined by the degree of their influence on pathogenesis.Conclusion. Conclusions. The study and understanding of the etiology of gingival recessions allows the clinician to select a personalised treatment taking into account individual characteristics that influence the recession occurrence and its condition: congenital and acquired factors; living conditions, habits, level of hygiene, as well as other components that aggravate or compensate for the degree and level of complexity of any recession - single, multiple or generalised. It is advisable to continue the study of literature data to expand the classification and detail the structure of etiological factors.
