Peparing the restoration for
polymerization
Remove the fully layered restoration from the model and add
Incisal material to the contact points. Make sure that the
material is fully adapted in the marginal areas, ie at the
transition between the metal and veneer.
When fabricating a bridge, separate the individual veneers
using a thin implement.
SR Chromasit Fluid forms a separation layer and
should therefore only be applied to surfaces. It
should not be used as a wetting agent to make
shape adjustments with SR Chromasit.
After polymerization, thoroughly remove SR Chromasit Fluid.
Polymerizing the veneer
Polymerize the veneer in the Ivomat (with water) at 120 °C
(148 °F) and 6 bar pressure for 7 minutes.
Finishing
Finish shape and contact points using appropriate grinding
instruments. Make sure to completely remove SR Chromasit
Fluid from the surfaces of the veneer.
Do not use coarse-grained diamonds, coarse burs or similar
instruments, as it is difficult to produce a sufficiently smooth
surface with this type of instruments.
