The article offers information on the effectiveness of metal ceramic crowns. At high temperature, metal ceramic crown can be altered following casting. Metal ceramic crowns have also been discovered to fit the model without complications. The dimensional stability of a metal ceramic crown was tested. It is stated that major distortions occur during oxide annealing rather than during porcelain firing.
