1 st and 2 nd Margin firing
A ceramic shoulder can be fabricated on the metal framework after the opaquer firing, if the necessary space has been
provided during finishing. Before creating the ceramic shoulder, seal the stone die with IPS Margin Sealer and then, after
drying, with IPS Ceramic Separating Liquid.
wrong correct
After that, the IPS Margin material in the respective shade is generously applied in drop-shaped increments in the cervical
area (i.e. the outer surface of the ceramic is given a convex design) and dried. Then, carefully remove the framework with
the dried shoulder material from the die.
tip:
When designing a ceramic shoulder (particularly for bridges), the Margin material may be applied slightly higher up in
the proximal areas. This will reduce the interdental shrinkage during the subsequent Dentin and Incisal firings.
