How can premature drying of the IPS Object

Fix Putty or Flow in the syringe be prevented?

In order to avoid a premature loss of moisture of

the firing pastes, remove the syringe from the

aluminium bag only directly before initial use.

Close the syringe immediately after usage. If the

syringe is not used for a longer period of time, it

can be stored in a resealable plastic bag together

with a moist paper tissue.

Can other firing trays, e.g. honey-combed

trays, be used for the crystallization of

IPS e.max CAD?

No other firing trays should be used. The IPS

e.max CAD Crystallization Tray

contained in the assortment stores

the heat necessary for slow and

above all tension-free cooling of

the glass-ceramic. Other firing

trays, e.g. honey-combed tray,

cannot store the heat and there-

fore cool down too quickly.

Can furnaces other than the ones from

Ivoclar Vivadent be used to crystallize

IPS e.max CAD restorations?

The crystallization of IPS e.max CAD is specially

coordinated with the Ivoclar Vivadent ceramic

furnaces (e.g. Programat P300, P500 or P700). If

you would like to use other, untested ceramic

furnaces, please consult Ivoclar Vivadent about

their compatibility with IPS e.max CAD. It is

important to note that not every ceramic furnace

can be used for crystallization. Ceramic furnaces

that, for instance, do not feature controlled long-

term cooling mode or vacuum cannot be used for

this purpose.

What must be considered after the firing of

IPS e.max CAD?

In order to prevent tensions within the ceramic,

remove the restoration from the furnace only

after the firing cycles have been completed

(wait for the acoustic signal of the ceramic

furnace). Allow the objects to cool to room

temperature in a place protected from draft and

do not touch them with metal tongs during that

time. Do not blast or quench the objects.

Which materials should be used if additional

shade adjustments are necessary after

Combination firing (Crystallization and Glaze

firing in one step)?

Since the characterizations have already been

carried out using IPS e.max CAD Crystall./Shades

and Stains for the Combination firing, IPS e.max

CAD Crystall./Shades and Stains have to be used

again for any corrective firing.

Can IPS e.max CAD Crystall./ Shades, Stains,

Glaze and IPS e.max Ceram Shades, Essences,

Glaze be used with one another?

No. Since the IPS e.max CAD Crystall. and the

IPS e.max Ceram materials have to be fired in a

different manner, the materials cannot be mixed

or applied at the same time.

Can IPS Empress Universal Shades, Stains and

Glaze be used for IPS e.max CAD?

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 the quality of crystallization of IPS e.max

CAD restorations be checked?

Optical inspection by means of the enclosed

materials shade guide can be conducted. If the

shade and opacity of the restoration match the

material shade guide, crystallization was success-

ful. The shade comparison must always be con-

ducted on a neutral-coloured background and

with incident light, rather than transmitted light.

If the shade and opacity of the restoration deviate

from that of the materials shade guide, e.g. too

translucent, the restoration must be milled again.

Crystallization cannot be repeated.
