Purpose: The purpose of this article is to characterize and compare the metallic biomaterials used in dentistry and analyze their structure, properties and chemical composition. Design/methodology/approach:In the research a sample of the following materials was used: Modiral S (cobalt alloy), Heraenium NA (nickel alloy), ARGELOY NP BE-FREE (nickel alloy), ARGENCO 75 SA (gold alloy). Observations was made using a scanning electron microscope Zeiss Supra 35 using secondary electrons and backscattered electrons at the maximum magnification of 20000x. Chemical composition analysis was performed using the scattered X-radiation detector EDS. The research included taking a series of photos of the structure of metallic biomaterials using optical microscope MEF4A ANNIVERSARY. Photos were taken with magnification at 100x, 200x, 500x, 1000x. Hardness testing of various materials was performed using a Vickers hardness tester FM-700. Findings: Studies confirmed a typical dendritic structure for all the alloys. In the structures of the tested alloys compact pores and discontinuity of the structures were observed. On the basis of microhardness of alloys, cobalt alloys, nickel and gold alloy, it was found that cobalt alloy Modiral S has the highest hardness (400 HV). Practical implications: The structure and mechanical properties of alloys determine their particular usage and applications which is important in the selection of materials for specific applications. The Modiral S alloy is used in production of prostheses and combined works. In contrast: Heraenium NA, ARGENCO 75 SA and ARGELOY NP BE-FREE are used in production of dental crowns and bridges. Originality/value: Metal alloys used in dentistry have varying properties. The appropriate structure and mechanical properties of these alloys determine their specific use in dentistry.
