The surplus material is taken off the casting and a fine grade bur like a stone bur is used all over the material post to eliminate any /problems that were bobbles and to clean the top. First, the feel is built up into exactly what the steel substructure's form is going to be. As it must be closely designed before it's included with the overhead the feel have to be dissolved.
In the event the polish does not go up towards the red line, the resulting top won't meet the patient's gum, and the gap allows food and germs to run under the overhead resulting in infection. It is not demonstrated in previous ways, but a spacer is employed on top of the post ahead of the wax is added so that there is enough of a gap involving the overhead as well as the article for this incredibly thin layer of concrete.
The steel that was excess is removed from the casting plus there is like a diamond bur a fine-grade bur used throughout the metal post to smooth the surface also to eliminate any bobbles/ problems. First, the feel is made up into exactly what the Investment Casting material substructure's model is likely to be. The polish have to be dissolved as it needs to be directly modified before it's added to the top.
