Ramus' M. The ground of metal alloys application bor the manufacturing of metalloceramic constructions of the dentures

The thesis in devoted to the studiing of the application of metal alloys for manufacturing of unremovable metalloceramic constructions of dentures on cobaltochromic and nickelechromic basises and that proposed by the author. There were determined the main physico mechanical properties of metal alloys after many times warming and there was mvestigated the microstructure of the conversional layer metal-porulain and the hardness of fixation. There was studied the influence of metal alloys on micro-biological condition of the oral cavity and their antimicrobic activity depending on the chemical composition of the dentiprosthetic material. There was investigated the degree and duration of inflammatory processes of mucous mambrane of strong teeth marginal parodontium depending on the type of the used metal alloy. There was conducted the differential investigation of histotoxicity of the alloys auording to the method of tissue culture ISO 10 993-5:1992. On the basis of the obtained Data there was proved the e xpediency of the application of metal alloys in dental practice.
