Abstract

Background:  Dental casting alloys have found wide spread usage in restorative dentistry due to their desirable physical, biological and economical properties. The recasting of previously casted alloy is a routine procedure in dental laboratories. The advantages of recasting include decreased overall cost, to prevent wastage of natural resources and environmental protection. Cast gold alloy is in use since long time as restorative material in dentistry, later subsequent demand for semi-precious and non-precious base metal alloys has increased. This lead to increase in the demand for base metal alloys which resulted in a substantial increase in the cost of these once insignificant alloys. In our current economy, it is obligatory that dentists and technicians be cost conscious about the materials they use, and this lead to increased recasting of the alloys. So, one should know about the properties of the recasted alloys without compromising the properties.
