Ivoclar Vivadent IPS e.max ZirPress - Manual (Page 70)

Why are the IPS e.max ZirPress ingots
available in different levels of translucency?
The user may select the suitable ingot depending
of the desired processing technique. The HT ingot
is particularly suitable for the staining technique,
the LT ingot for the cut-back technique and the
MO ingot for the layering technique.
Can IPS Empress Universal Shades, Stains and
Glaze be used for IPS e.max ZirPress?
IPS Empress Universal Shades, Stains and Glaze
were specially developed for and coordinated with
the IPS Empress System and are therefore not
suitable for IPS e.max products.
Can IPS Alox plungers also be used for
IPS Empress?
IPS Alox plungers have been exclusively designed
for the IPS Investment Ring System. Since the
diameter was increased, the IPS Alox plunger does
not fit into the IPS Empress investment ring
system.
Can the IPS Alox Plunger Separator also be
used for other pressed ceramics, such as
IPS Empress Esthetic?
The IPS Alox Plunger Separator can only be used
for IPS e.max Press and IPS e.max ZirPress ingots,
since the press temperature of the IPS Empress
Esthetic ingots of 1075 °C (1967 °F) is too high
and results in the Separator losing its effect.
Can press furnaces other than the ones from
Ivoclar Vivadent be used to press IPS e.max
ZirPress ingots?
IPS e.max ZirPress has been especially coordinated
with Ivoclar Vivadent press furnaces (e.g.
Programat EP3000, EP5000). If other press
furnaces are used, the parameters may have to be
adjusted accordingly by the user.
Can IPS e.max ZirPress restorations also be
conventionally cemented?
IPS e.max ZirPress restorations can be cemented
adhesively, self-adhesively or conventionally,
depending on the indication. For conventional
and/or self-adhesive cementation, an appropriately
retentive preparation design must be observed. If
this is not possible, adhesive luting should be
preferred, e.g. with Multilink Automix. Vivaglass
CEM is available for conventional cementation.
SpeedCEM is recommended for self-adhesive
cementaion. It is not advisable to use classical
phosphate cements, as they would negatively
influence the light transmission of the all-ceramic
and therefore compromise the esthetic
appearance of all-ceramic restorations. Pressed-
over inlay-retained bridges and veneers must be
placed with the adhesive technique.
