The ceramic material is applied according to the layering diagram.
Restoration after the 1 st Dentin / Incisal firing
For an optimum firing result, the interdental areas must be separated down to the opaquer.
1 st dentin and Incisal firing
Isolate the model before layering the Dentin and Incisal materials. In this way, the ceramic material is prevented from dry-
ing out or sticking to the model respectively. Isolate the stone die and the adjacent areas using IPS Model Sealer.
Additionally, separate the area of the pontics with IPS Ceramic Separating Liquid.
tip:
To achieve an optimum bond between the ceramic material and the opaquer surface, apply a small amount of
IPS InLine Deep Dentin or Dentin material to the cervical and interdental areas (for bridges) and slightly roughen it.
In this way, the adaption of the ceramic material on the opaquer surface is enhanced.
tip:
Densify the ceramic surface (after contouring) with a large, dry brush toward the cervical margin before firing.
Make sure that the restoration is slightly overcontoured so that the actual tooth shape is achieved after firing. The bridge
is lifted off the model to supplement the contact points with Dentin and Incisal materials. Before firing, separate the entire
interdental area down to the opaquer.
Important
• Use distilled water to rewet the mixed or even already applied layering material.
• The firing tray with the restoration should only be placed in the firing chamber and removed from it once
the furnace head is completely open and the beeper has sounded.
