This paper presents results of microscopic examination and properties comparison of commercial Ni-Cr-Mo alloys (Remanium G-soft and Remanium CSe alloy) commonly used in dental laboratories. The study confirmed that a small change in the content of the basic components of the alloy, has a very large impact on the structural construction of alloy, and consequently on the properties of the alloy. The increased molybdenum content favors the segregation of the components and thus makes it possible to apply the Ni61Cr26Mo11Si1.5(Fe,Co,Ce)x (x < 1) as a based material for prosthetics substructure veneered with ceramic material.

This paper presents the possibility of carrying out a structural quantitative analysis of the alloys commonly used in dentistry. On the basis of microscopic observation and digital treatments (LUT and binarization) it was possible to determine the contribution of the phase structure of the Ni-Cr-Mo alloy. The results revealed that differences in the chemical and structural composition of Remanium dental alloys, easily identifiable on the basis of digital image analysis.
