2 nd Margin firing (optional)
After firing, the shoulder may require minor adjustments by grinding. Observe the following procedure for the 2 nd Margin
firing:
– Isolate the die once again using IPS Ceramic Separating Liquid.
– Complete the areas affected by shrinkage and any missing areas using the same Margin material that was used for the
1 st firing.
– Depending on the size of the gap, the shoulder material may be slightly vibrated.
– Carefully remove the framework with the completed and dried shoulder from the die, position it on the firing tray, and
fire.
– After the 2 nd firing, the shoulder may require minor adjustments to achieve ideal accuracy of fit.
Complete the areas affected by shrinkage and any missing areas using the same Margin material that was used for the 1 st firing
If necessary, slightly adjust the fired shoulder by grinding to achieve very good accuracy of fit.
Firing parameters for the 2 nd Margin firing (note the temperature control)
Important:
If the fit of the shoulder is to be optimized during the subsequent Dentin and Incisal firing, mix the corresponding Margin
material with the Add-On Margin material in a 1:1 ratio and fire using the firing parameters for the Dentin / Incisal firing.
