Abstract

Cast metal restorations were introduced in dentistry about 100 years ago and soon they became a subject of great interest to both dentists and patients. Most advantageous property of gold alloy is its malleability, and when properly manipulated, it has wear similarly to that of tooth structure. Cast gold restorations became most popular from the 1930s to the 1970s because of their acceptable functions and restorative longevity. Most of the cast metal restorations are made from alloys formed by combination of gold with other metals such as silver, copper, zinc, platinum and palladium. Casting procedures have been used for replacement of teeth by means of fixed and removable partial denture prosthesis, and full mouth restorations. In operative dentistry, cast metal restorations are mainly used in three forms viz. Inlay, Onlay, Partial crown.
