One of the most important criteria of assessing of the quality manufactured prostheses and the functional state of dentoalveolar system is restoration of the degree of chewing efficiency. Chewing efficiency is determined by the help of classical methods, and by the help of modern technologies and mostly depends on the quality of the manufactured structures. The production of qualitative complete removable prostheses is dependent on the properties of the basic material. The main group of materials for the manufacturing of such structures is acrylic plastics of hot polymerization. Orthopedists often use thermoplastic plastics for manufacturing of complete removable prostheses nowadays. These basic materials allow avoiding the disadvantages of acrylic base plastics, and improving the functional qualities of removable dentures. Aim. The work is concerned with study in the clinic of orthopedic dentistry the results of treatment of patients with complete absence of teeth with prostheses made of thermoplastic material «Deflex Acrylato», using various functional tests. Materials and methods. During all the work, the thermoplastic plastic «Deflex Acrylato» was used. The quality evaluation of all our designs was carried out with the help of an objective – subjective test «BOFSAC», determination of biopotentials of masticatory muscles with the help of electromyography and determination of masticatory efficiency according to I.S. Rubinov. Results. As a result of our work, it can be determined that the use of the basic thermoplastic material «Deflex Acrylato» allows achieving better fixation and stabilization of complete removable prostheses, which is subjectively confirmed by the «BOFSAC» test, objectively – data of electromyographic studies and time indices of the masticatory test by I.S. Rubinov. Conclusions. Based on the results of our studies, one can conclude that adaptation to prosthesis made from the basic thermoplastic material «Deflex Acrylato» is short-timed and almost painless.

Background. The problem of providing high-quality dental care to edentulous patients remains one of the most important and unresolved to this day in the clinic of prosthodontics. The causes of complete loss of teeth can be both periodontal tissue diseases and diseases of hard tooth tissues of carious and non-carious origin, trauma and the like. It becomes necessary to fabricate complete removable dentures to prevent the occurrence of pathologies in such situations. Complete secondary adentia leads to a large number of local and general complications. The chewing apparatus undergoes a number of functional and morphological changes. Therefore, the complete absence of teeth sets the dentist the task of restoring the functions of full chewing, the appearance of the patient, and speech. The complexity of high-quality prosthetics for edentulous patients is also because the clinical characteristics of supporting tissues are diverse, constantly changing, so a personal approach to creating stable denture is needed. It should be added that the fabrication of high-quality complete removable dentures largely depends on the properties of the base material. The main group of materials for the fabrication of such dentures is acrylic plastics. The aim. The work is focused on the study of the functional state of the masticatory muscles and the restoration of masticatory effectiveness in edentulous patients, for whom dentures were made in the prosthodontics clinic from the acrylic base material «Ftorax». Material and methods. Hot curing plastic based on fluorine-containing acrylic copolymers «Ftorax» was used in the work. Our evaluation of the quality of all constructions was carried out using the «BOFSAS» test, determining the biopotentials of the masticatory muscles using electromyography, and determining the masticatory effectiveness according to I.S. Rubinov. Results. Based on our work, it can be noted that the use of the basic acrylic material «Ftorax» allows us to achieve good fixation and stabilization of complete removable dentures, which is subjectively confirmed by the «BOFSAS» test, objectively – by the electromyographic studies and time indices during chewing test according to I.S. Rubinov. The amplitude during volitional compression is 556.90±8.72 μV, which approaches the norm (641.58±10.01 μV), and almost four times higher than before prosthetics (188.11±8,13 μV) after 1 year of constructions using. A similar pattern is observed with arbitrary chewing: the amplitude (547.32±8.43 μV) approaches normal (643.92±9.11 μV) compared with the results before prosthetics (201.40±9.39 μV). As for the coefficient «K», its value decreased almost twofold compared with the results before prosthetics (2.44±0.14) and equals to 1.25±0.03, which is significantly closer to normal (1,02±0.01). After the test by Rubinov the following results were obtained: the average time that patients with intact dentitions spent chewing on the stimulus was approximately 12.97±0.13 seconds and the average time for patients before prosthetics (with old dentures) was approximately 45.16±0,41 sec. The time that patients spent chewing a nut after 1 month was 28.97±0.42 seconds, after 6 months – 26.94±0.44 seconds, and after 1 year of using the entures – 25.48±0.45 sec. Based on this, it can be summarized that adaptation to such dentures takes place at the appropriate time with minor corrections. Conclusion. The results of our clinical study indicate the feasibility of using «Ftorax» in prosthodontics clinic for treatment of edentulous patients.

Abstract The article is aimed at evaluation of chosen properties of thermally sprayed coatings based on tungsten carbide. It was evaluated two types of coatings – WC-FeCrAl and WC-WB-Co. The coatings were deposited on basic material steel AISI 316L. The aim of experimental works was to determine the quality and resistance of coatings in corrosion environment depending on number of thermal cycles. The quality of coatings was evaluated by determination of their adhesion depending on thermal cycles, determination of microhardness and indentation fracture toughness. Coatings were exposed in tribo-corrosion conditions with the presence of 1% NaCl. The results of experimental showed a higher quality of coating WC-WB-Co.

One that influences human resource indicators is education. The teacher is a profession as a job of academic specialization in a relatively long time in college. Understanding related to teacher competence is very important to have by a prospective teacher because it can affect the quality of performance as a professional teacher. The teacher's competence is known as pedagogic, professional, social and personality competencies. The issue in this study is how the competency of the teacher of the Department of Geography Education FKIP Unsyiah as a prospective teacher of geography? The purpose of this study was to determine the competence of teachers in the Department of Geography Education FKIP Unsyiah as prospective geography teachers. Quantitative description approach is used in this study to find answers to the issue. The population in this study were students of the Department of Geography Education FKIP Unsyiah class of 2015 and 2016 who had been declared to have passed the Micro Teaching and Magang Kependidikan 3 course totaling 50 people. Because the population is small and can be reached, the determination of the sample using total sampling techniques so that the sample in this study is the whole population. Data collection is done by distributing test questions to respondents. The data was analyzed using the descriptive statistics percentage formula. The results of the study indicate that the level of teacher competence of Geography Education Department students as prospective teachers is in the moderate category, namely as many as 22 respondents (44%). A total of 12 respondents (24%) were in the high category, 15 respondents (30%) were in the low category and 1 respondent (2%) were in the very low category.

The article focuses on examining the influence of fluctuations in annual precipitation amount on the quality of surface waters. Water quality was estimated with data on BOD, COD and phosphate–ion concentration within five selected regions of Ukraine. Analysis of the precipitation data (1991 – 2010) showed different regional trends. Using the statistics, determination of the interconnection between precipitation amount and water resources quality were done. The obtained regularities and associated uncertainties can be used for prediction of changes in water resource quality and as a guide for future adaptation to possible climate change.
