“…Its excess reduces the physical and mechanical properties of base plastics and causes premature "aging" of the material. In modern scientific periodicals there are some works devoted to the study of the influence of basic dental plastics on hematological parameters of blood [14][15][16]. The monomer is a strong organic solvent and promotes the activation of procoagulants, which are involved in the initial stages of blood clotting.…”

Summary. The effectiveness of orthopedic treatment significantly depends on the properties of the basic plastics used in the manufacture of dentures. The aim of the study – to study the effect of acrylic plastics "Ftoraks" and "Villacryl H Plus", the polymerization of which was carried out by different methods, on the main hematological parameters. Materials and Methods. The study and comparative characterization of the possible toxic effects of dental base acrylic plastics "Ftoraks" and "Villacryl H Plus", which were polymerized by different methods, on the main hematological parameters were performed on white outbred rats, which implanted samples of these materials in periodontal tissue. Results and Discussion. As a result of the study, it was found that animals implanted with samples of the above acrylic plastics polymerized in a "water bath" methodic in the blood had a decrease of hemoglobin, leukocytosis, increased number of band and segment nuclear neutrophils, increase in the number of eosinophils and decrease of basophils in comparison with the control and other groups of animals. In the study of samples polymerized in the apparatus for dry polymerization under pressure and in the apparatus for molding plastics, it was found that fluctuations in the content of the main hematological parameters are within the physiological norm and do not differ significantly from the control. Сonclusions. Dental basic acrylic plastics "Ftoraks" and "Villacryl H Plus" polymerization of which was carried out by the method of dry polymerization with pressure and in the apparatus for foundry pressing of plastics cause less toxic effects on hematological parameters of the blood.

Introduction. The environment of the oral cavity is a complex electrolyte environment with variable pH values, in which metal restorations release metal ions. These ions can induce cell apoptosis through intrinsic and extrinsic pathways. Dental alloys require excellent wear resistance and biocompatibility, which can extend the service life of removable prostheses. Aim. To study the composition of microelements and pH in the oral fluid in the presence of fixed cast prostheses made of cobalt-chromium and nickel-chromium alloys Remanium GM 700 and Remanium CSe of certified delivery and after multiple remelting. Materials and methods. 120 patients aged 25 to 60 took part in our study, including 79 women (65.9%) and 41 men (34.1%), who were divided into 4 groups of 30 people each. In the presented research studied the composition of microelements and pH in the oral fluid in the presence of fixed cast prostheses made of cobalt-chromium and nickel-chromium alloys Remanium GM 700 and Remanium CSe of certified supply and after multiple remelting. Depending on the type and topography of the defect in the dental row, patients were made permanent cast dentures. Results. After 7 days, the pH value shifted to the acidic side in people who were made solid-cast constructions with the specified alloys, and after 3 months it reached a neutral value. The dynamics and degree of expression of the change in pH depend on the timing of the study, the quality of the alloy, and the technological process of manufacturing solid-cast structures of dental prostheses. Conclusions. We determined that the composition of microelements of oral fluid in the presence of solid-cast prostheses changes under the influence of random factors. The studied alloys do not harm the patient's organism and therefore can be used for the production of solid-cast constructions of dental prostheses.

The aim: To determine the needs of the population of the Ternopil region in prosthetics with removable orthopedic dentures and to study the physical and technological properties of different types of base plastics. Materials and methods: The needs of Ternopil and Ternopil region population in removable prosthetics were studied on the basis of consolidated annual reports of city and district dental clinics of Ternopil region. Base dental plastics «Ftoraks» (Stoma, Ukraine) and «Villacryl H Plus» (Zermapol, Poland) were used to study the physical and mechanical properties (deformations during compression and tension). Results: As a result of our research, we found that the need of the Ternopil region population for removable prosthetics is quite high. When analyzing the choice of designs of removable laminar prostheses, it was found that 64.99 ± 0.14% of patients required the manufacture of partial removable dentures, and 35.01 ± 0.18% – complete removable dentures. A significant difference was found in the physical and technical characteristics of the samples of the studied plastics, which were polymerized by various methods. Conclusions: Dental base plastic «Villacryl H Plus», which was packaged and polymerized by casting, has significantly higher physical and mechanical properties than dental base plastic «Ftoraks».
