V. Ukraine, Kharkiv, Kharkiv National Medical University, orthopedic dentistry department Abstract. The work is devoted to clinical studies of enhanced alginate impression material with decontamination properties. The use of this material in orthopedic treatment of patients with generalized periodontitis of I-II degree is described. A comparative analysis of the usage of an enhanced alginate impression material with decontamination properties and a dust-free alginate impression material in patients with this pathology was carried out. Keywords: alginate impression material, decontamination, impressions, models, immediate- prosthesis, clasp prosthesis, splinting elements, generalized periodontitis. At present there is a marked increasing in the incidence of viral hepatitis B and AIDS worldwide, taking on the nature of the pandemic. In this regard, in the orthopedic dentistry, the problem of disinfection, decontamination of prints becomes especially relevant. There is a danger of infection of dentists, dental technicians, auxiliary staff of dental clinics and patients [1, 2]. Dentists and dental technicians belong to the group of occupational risk of HBV and AIDS. The increased risk of morbidity is due to the fact that prints of prosthetic lids of removable dentures are in contact with the blood and saliva of patients who may be carriers of these diseases and are contaminated with pathogenic microbiota [3]. Taking into account the urgency of the problem for orthopedic dentistry, in our study, we aimed to improve the composition of the domestic impression alginate material, which recipe contains peroxide K-30, which provides the property of decontamination to imprints, the perfect composition of the material in an optimal amount. We have been refined and experimentally substantiated the formulation of enhanced alginate impression material (EAIM) by introducing into its composition a compliant antiseptic, developed an instruction for its use [4, 5]. According to the results of experimental studies, the physico-chemical properties of the EAIM were determined and the decontamination efficiency of the improved composition of the material was determined by the effect on the tissue of the prosthetic bed, imprints and plaster models [6, 7]. The purpose of the study is to evaluate the efficacy of the clinical use of EAIM with peroxide K-30. Tasks of the research. To carry out orthopedic treatment of patients using EAIM and its prototype – dust-free alginate impression material (DFAIM) in order to compare the clinical effectiveness of their use. Materials and methods of research. We, in terms of clinical practice of orthopedic dentistry, used the EAIM to obtain the impression of prosthetic beds in the treatment of patients with the presence of chronic generalized periodontitis. For these patients, we produced imediate-prostheses and clasp designs of prostheses with tire-like elements, according to indications for the use of alginate imprints. In the selection of patients with periodontal diseases for orthopedic treatment, the main indications for the use of removable dentures: dental prostheses with tuneus properties and direct (imediat-prostheses), with indications for dental extraction operations, were guided by the basic indications. Also, a comparative analysis of the clinical and functional efficiency of the use of the EAIM and BAVM was conducted. The indicator of comparative clinical and functional efficiency was calculated by us as a percentage correlation between the frequency of correction of the bases of dentures in the main and control groups. In total, 120 patients were treated. The main group included 80 patients who underwent orthopedic treatment with the use of EAIM for receiving prints. The control group consisted of 40 patients, who used DFAIM to receive imprints. Clinical studies were conducted before and after the receipt of the original fingerprints in the electorate of 120 patients who were in the age range of 19 to 65 years. Patients were divided into
