With the available Visalys
®
effect of the selected composite shade can be checked on the
slightly moist core prior to final cementation. Apply the paste
in the selected shade on the inside surfaces of the restoration
and check the shade effect on the restoration. The shade of
the Visalys CemCore Try In Paste matches the shade of the
®
cured cementation composite.
Remove the Visalys CemCore Try In Paste from the resto­
®
ration and core surface with water.
After the try­in, the surfaces of the restoration that may be con­
taminated with saliva, blood or silicone residues, for example,
have to be cleaned with water spray or in the ultrasonic bath
with distilled water and then dried with water/oil ­free air. All
the surfaces must be free of contamination.
In the case of restorations made of non­precious metal or oxide
ceramics, there may be no cleaning with phosphoric acid.
A rubber dam is recommended for a dry operating field.
