Документ Biological compatibility of metal structures of dentures made from multiple melted alloys(2022) Hasiuk, Petro; Kindiy, Dmytro; Radchuk, Volodymyr; Kindiy, Viktor; Demkovych, Andrii; Yarkoviy, Vitaliy; Гасюк, Петро Анатолійович; Кіндій, Дмитро Данилович; Радчук, Володимир Богданович; Кіндій, Віктор Данилович; Демкович, Андрій Євгенович; Ярковий, Віталій ВасильовичThe issue of reuse of metal alloys in dentistry raises debatable questions about their impact on the human body. The aim of the study was the evaluation of the biocompatibility of metal structures of dentures made from cobalt-chromium and nickelchromium alloys Remanium GM 700 and Remanium CSe after repeated vacuum remelting. Materials and methods. Clinical study and treatment with fixed prostheses based on Remanium GM 700 and Remanium CSe were performed among 120 patients aged 25-60 years. The biocompatibility of the above-mentioned denture designs with oral tissues was studied. Results. Prostheses made from Remanium GM 700 and Remanium CSe alloys are biologically indifferent, which is confirmed by the indicators of alkaline and acid phosphatase activity within the physiological norm. Regardless of the number of remelts, these alloys do not cause dysbacteriosis. The obtained results do not depend on the terms of observation, which indicates the safe use of remolten alloys for dental prosthetics. Conclusions. The investigated alloys are biocompatible and can be used for the manufacture of solid structures of denturesДокумент Characteristics of metal alloys properties for dental casting after their repeated remelting(Aluna Publishing, 2021-10) Hasiuk, Petro; Kindiy, Viktor; Radchuk, Volodymyr; Kindiy, Dmytro; Dzetsiukh, Tetiana; Korol, Dmytro; Гасюк, Петро Анатолійович; Кіндій, Віктор Данилович; Кіндій, Дмитро Данилович; Король, Дмитро МихайловичThe aim: To study clinical and experimental substantiation of the possibility of using cobalt-chromium and nickel-chromium alloys after repeated remelting for non-removable one-piece prosthetics. Materials and methods: Experimental studies of Remanium GM 700 and Remanium CSe dental alloys have been carried out. To study the physical and mechanical properties of alloys, samples were obtained by sequential six-fold remelting in a Tiegelschleuder TS casting dental unit manufactured by Degussa. All samples were subjected to chemical analysis and metallographic studies by methods generally known in metallurgy, which included studies of microhardness, elasticity, tensile deformation, bending deformation and alloy structure after repeated remelting. Results: Thus, the obtained results of the chemical, physicomechanical and structural properties of the remelts indicate that the Remanium GM 700 and Remanium СSe alloys can be reused many times for the manufacture of one-piece orthopedic structures in that they are identical with certified alloys. Conclusions: In terms of structure, qualitative and quantitative composition of elements, physical and technological properties, the Remanium GM 700 and Remanium CSe alloys have been repeatedly remelted meet the requirements of materials used in biologically active environments of the patient’s body. High-quality and cost-effective remelted multiple times Remanium GM 700 and Remanium CSe alloys can be recommended for use in practical prosthetic dentistry six times.Документ Discussion on individual educational trajectory as an integral component of continuous professional development(Національний технічний університет України «Київський політехнічний інститут імені Ігоря Сікорського», 2023) Mazur, Iryna; Hasiuk, Nataliia; Drohomyretska, Myroslava; Popovych, Ivan; Radchuk, Volodymyr; Мазур, Ірина Петрівна; Гасюк, Наталія Володимирівна; Дрогомирецька, Мирослава Стефанівна; Попович, Іван Юрійович; Радчук, Володимир БогдановичAbstract. The system of continuous professional development of doctors in Ukraine needs detailed analysis and comprehensive dynamic monitoring to become a process that includes the possibility of a doctor’s professional growth. The research aims to monitor approaches to the continuous professional development of dentists for the formation and improvement of professional competence skills by highlighting the role of individual educational trajectory based on the priority of work formats with professional information, methods of familiarization with it and its receiving. 2216 respondents took part in the research, filling out a questionnaire during scientific and practical events of professional schools for dentists in online mode in March 2023, which included questions on the definition and objectification of forms, formats, ways of implementing continuous professional development and the vision of approaches to acquiring new knowledge and skills. The data obtained was processed using the StatSoft Inc licence program. Analytical research methods and structural-logical analysis were applied. According to the survey results, an individual's educational trajectory should include attending lectures, professional seminars, working with scientific and practical publications. The main quality requirement for publications is their good illustration of clinical cases and algorithms for working with patients. The analysis results of the rating parameters of professional dental journals declare the request of the dental community to improve the quality of material content, visual design and a possible change in positioning.
