The Ni-Cr dental alloys are among the oldest restorative materials used in dentistry. Reuse of previously melted and cast dental alloys is a routine procedure used in dental laboratories to reduce the cost of dental restorations. Continuous reuse of the commercial Ni-Cr dental alloys, such as Wirron 99, can change numerous properties of these materials, and therefore the present study was aimed to establish the outcome of several recasting cycles on the Wirron 99 alloy properties. Obtained results reveal that alloy recasting resulted in the appearance of typical dendritic microstructures where the chemical composition of dendritic and interdendritic regions differs. Moreover, the results of the present study showed that the number of recasting cycles has a significant effect on the alloy microstructure, structure, electrical conductivity, and hardness
