InLine
® – Veneers
IPS
The following chapter shows the step-by-step layering of veneers on refractory dies.
Important: After each working step, the master model has to be immersed in water for about 5–10 minutes, depending
on the size.
tip:
For the veneer fabrication, smaller working steps and several intermediate firing cycles are recommended.
Model fabrication
Fabricate a duplicate model using a commercially available refractory
die material, e.g. BegoForm
® from Bego, Cosmotech VEST from GC
or G-CERA TM VEST from GC (observe the instructions of the
manufacturer).
Important: Correct processing and properly degassed dies are an
important prerequisite for accurately fitting veneers.
Wash firing
After degassing the refractory dies, apply IPS InLine Add-On mixed
with the IPS InLine System Glaze and Stains Liquid in a thin layer
and fire.

cervical firing
Build up the marginal areas using a mixture of IPS InLine Dentin
and, for example, Occlusal Dentin brown.

dentin/Impulse firing
Internal layering is modelled to the natural characteristics and con-
sists of a dentin build-up and various effects. Individual layering with
the Impulse materials enables mamelons, opalescence and translu-
cent effects to be achieved.
