These type of crowns and bridges have a metallic body and prove to be a cost effective option for posterior teeth. An acrylic or ceramic facing contributes to the aesthetics in such type of restorations. Advantage of this type of crown or bridge is the low cost, strength of the metal and longevity. Plus very less tooth structure is lost while preparing the tooth for a crown or bridge.
The disadvantage is the aesthetics since there is a possibility of the metal showing in cases of acrylic facing wearing off due to long term use. The normal life span of such restorations is 6 - 8 years.
