The color of castable ceramic crown was affected by the color of the dowel-core in some circumstances.
The use of castable ceramics for dowel-cores has the advantage of good color. But the strength of the castable ceramic dowel-cores must be examined. The castable ceramic dowel-cores were not as strong as metal dowel-cores.
Thus prefabricated dowels were made for castable ceramic dowel-cores.
