In order to obtain fix or mobile dental prostheses, there are used a large variety of metal
alloys, making difficult to evaluate technical, biological and clinical properties of these
materials. The present study establishes the key role of heating and casting process for Ni–
Cr alloys, in order to improve the physico-chemical properties and quality of the obtained
physiognomic dental restorations. Using electron microscopy, we made first a comparison
between qualities of the surfaces of crude and processed materials. Through EDX …
