In this method a wax pattern of tooth crown or bridge is made, surrounding this pattern with an investment material, letting this harden, then melting wax and burning out the wax to produce an intricate and accurate mold was conceived. The next step involved is melting the metal and pouring it into the cavity. After cooled down, prepared product is removed from investment, finishing, sand blasting and polished.

• In this casting method for metal framework, there are chances of casting errors like porosity, metal shrinkage after casting, voids and sometimes errors may be due to improper wax pattern handling. 
• The casting error like porosity and voids are result in deficiency in properties of metal compromised the strength of dental restoration.
• The metal shrinkage after casting result in improper fit of crown over model, then technician grind the inner fitting surface of crown to seat crown on model, result in improper fit of crown, marginal integrity compromised, result in leakage near margin, leads to secondary dental caries.
