6.8 Further Information
Hint:
The reaction layer which develops during
pressing lithium disilicate , depands also
on the type of the investment which
was used.
Our internal examinations cannot consi-
der all investment materials offered in
the market. However, the following
investments show good results when
processing lithium disilicate:
•
IPS PressVEST Speed (Ivoclar)
•
Zubler HS-PC
