Your purchase of IPS e.max means you have chosen more than simply an all-ceramic
system. You have taken the decision to benefit from the unlimited possibilities of all-
ceramic. IPS e.max delivers high strength and highly aesthetic materials for the PRESS
and the CAD/CAM technology.
The IPS e.max products are unique. They are recognized for their outstanding
properties as well as exceptional versatility and flexibility – and they produce results
with maximum aesthetics.
The components for the PRESS technique include the highly aesthetic glass-ceramic
IPS e.max Press ingots and the glass-ceramic IPS e.max ZirPress ingots for pressing onto
zirconium oxide. Depending on the case requirements, two types of materials are
available for CAD/CAM techniques: the innovative IPS e.max CAD glass-ceramic blocks
and the high-strength zirconium oxide IPS e.max ZirCAD.
The IPS e.max System is further enhanced by the nano-fluorapatite layering ceramic
IPS e.max Ceram, which is used as a veneering material for all the IPS e.max
components – either glass-ceramics or zirconium oxide ceramics.
This proves that really exceptional all-ceramic systems are well designed. The system
allows you to take advantage of a single, standardized layering scheme to offer your
dentists and their patients restorations with maximum individuality and naturalness.

IPS e.max ZirPress is a fluorapatite glass-ceramic ingot for the PRESS-
ON technique. The fluorapatite crystals contained in the material are
of different sizes and therefore
selectively control the relationship
between translucency, opalescence
and brightness of the restorations.
Consequently, complete masking of
the less translucent zirconium oxide
frameworks is achieved. The PRESS-ON technique allows you to take
advantage of the benefits of the PRESS technique (accuracy of fit)
and CAD/CAM processing (milling of zirconium oxide). IPS e.max
ZirPress can be pressed onto both IPS e.max ZirCAD single tooth
copings and multi-unit bridge frameworks. Very little time and effort
is required to press the IPS e.max ZirPress ingots onto the frame-
works or copings using the proven PRESS technique. The ingots can
either be used to create a fully anatomic restoration or a dentin core
(cut-back). Frameworks onto which IPS e.max ZirPress has been
pressed demonstrate precision, heat resistant ceramic shoulders.
The restorations can be either characterized or veneered with the
efficient IPS e.max Ceram material. The superior aesthetic and
functional restorations achieved with these materials are cost-
effective and fully satisfy individual patient requirements.

Can IPS e.max ZirPress also be pressed onto other zirconium
oxide frameworks?
IPS e.max ZirPress can be pressed onto frameworks made of sintered
zirconium oxide or HIP zirconium oxide as well as presintered
zirconium oxide in the CTE range of 10.5–11.0 x 10-6 K-1
(100–500 ºC). The following zirconium oxides have been tested for
this purpose:
– KaVo – Bio ZS (coloured and uncoloured) and Bio ZH Blanks
– Nobel Biocare – Procera Zirconia
– DeguDent – Cercon Base
– 3M/Espe – Lava Frame (coloured and uncoloured)
– DCS – DC-Zirkon
– Digident – Digizon
– Cad.esthetics – Denzir
– Vita – In-Ceram 2000 YZ Cubes (coloured and uncoloured)
– Diatomic – Diadem/Diazir (coloured and uncoloured)
– Wieland – Zeno Zr Disc
Can IPS e.max ZirPress be pressed onto implant abutments?
IPS e.max ZirPress can be pressed onto zirconium oxide abutments
in the CTE range of 10.5–11.0 x 10-6 K-1 (100–500 ºC). The
abutments should not be too small and they must provide adequate
support for the shape and cusps. The instructions of the individual
manufacturers should be observed.
Can IPS e.max ZirPress be used to fabricate single crowns
without zirconium oxide copings?
IPS e.max ZirPress has been developed for the press-on technique.
The strength of the ingots is not sufficient for crowns without
zirconium oxide copings. Therefore, the ingots can not be used for
this indication.
Can IPS e.max ZirPress be used to fabricate inlays and onlays?
IPS e.max ZirPress has been developed for pressing onto zirconium
oxide. Therefore, the shades have been specially developed for this
application. From a materials science point of view, inlays and onlays
can be fabricated using this material. However, the aesthetic
potential of the product is limited because of the opacity of the
ingots. This must be taken into consideration during fabrication.
Can IPS e.max ZirPress be pressed onto only a part of a resto-
ration (eg on a shoulder or pontic)?
IPS e.max ZirPress can be pressed onto selected parts of a restora-
tion, if the instructions for use, the necessary minimum thickness of
the ceramics and the following points are observed. The sprues
must be attached directly, for example, to the ceramic shoulder.
During spruing and placement on the IPS e.max ring base, adequate
stability of the restoration and the waxed up areas must be ensured.
The fired ZirLiner areas which remain free from the pressed material
must not come in contact with the investment material, to prevent
the formation of bubbles during the subsequent firing procedures.
Therefore, the fired ZirLiner must be coated with a thin layer of wax.
This layer prevents the liner from coming in contact with the
investment material and also makes divestment easier, as the
investment material peels off without blasting. The removal of the
reaction layer with Invex Liquid does not have a negative influence
on ZirLiner. The ZirLiner surface must be protected in the final bla-
sting process in which the reaction layer is completely removed with
Al2O3. Wash (foundation) firing has to be carried out, even if
ceramics are only pressed onto certain areas of the restoration to
improve wetting.
Can veneers be fabricated with IPS e.max ZirPress?
IPS e.max ZirPress has been developed for pressing onto zirconium
oxide and the shades of the material have been adjusted for this
purpose. However, from a technical point of view, veneers can be
fabricated with this material. For example, if veneers are required in
the anterior region for a large restorative case and if the shade of
the IPS e.max ZirPress ingot corresponds to the demands of the
patient, veneers can be pressed (in the same investment ring).
The cut-back technique allows the veneers to be individually
characterized with IPS e.max Ceram. Veneers made with IPS e.max
ZirPress must be placed with the adhesive technique.
Can IPS e.max ZirPress be pressed onto inlay-retained bridges?
IPS e.max ZirPress LT ingots can be pressed onto zirconium oxide
inlay-retained bridges. In the creation of the zirconium oxide frame-
work, the minimum thickness of the connectors and the inlays
(min 0.5 mm) must be observed. All the areas at the preparation
margins should be fabricated with IPS e.max ZirPress rather than
zirconium oxide, since the press ceramic can be etched. This allows
a sound bond to be established between the press ceramic, the
luting composite and the prepared tooth.
Can IPS e.max ZirPress be pressed onto IPS Empress
CosmoPost?
IPS e.max ZirPress ingots can be pressed onto IPS Empress
CosmoPost. An excellent bond is achieved. Because of the large
selection of IPS e.max ZirPress ingots, very natural-looking
restorations are achieved.
Can IPS e.max ZirPress be pressed onto glass-ceramic
frameworks made of IPS e.max Press or IPS e.max CAD, for
example?
IPS e.max ZirPress ingots can only be pressed onto zirconium oxide
materials. The press temperature of 910–915 ºC (1670–1679 °F) is
too high for glass-ceramic frameworks. Consequently, they would
become deformed during the press procedure.

What is the purpose of the IPS e.max Ceram ZirLiner?
IPS e.max Ceram ZirLiners are translucent. Their three major
purposes are as follows:
1. They enable a strong, homogeneous bond with the zirconium
oxide framework.
2. They provide the white, non-coloured zirconium oxide frame-
works with chroma, an in-depth effect, and a shaded character
without increasing their opacity
3. They also provide the non-fluorescent zirconium oxide frame-
work with a natural fluorescence, thus enabling the fabrication
of lifelike restorations
Which type of IPS e.max Ceram ZirLiner should be used on
shaded zirconium oxide frameworks?
The clear IPS e.max Ceram ZirLiner should be used on shaded
zirconium oxide frameworks. The transparent character of the
IPS e.max Ceram ZirLiner does not affect the framework shade.
An outstanding bond as well as natural-looking fluorescence is
achieved. When shaded frameworks are used, the colour
compatibility of the IPS e.max ZirPress ingots and that of the
framework must be ensured.
Can IPS e.max ZirPress be pressed onto zirconium oxide
frameworks without the application of IPS e.max Ceram
ZirLiner?
A suitably shaded IPS e.max Ceram ZirLiner must always be applied
before waxing up. The IPS e.max Ceram ZirLiner generates an
outstanding bond and gives the restoration an effect of depth with
regard to the colour and fluorescence.
Why is the IPS e.max Ceram ZirLiner powder green and how
should it be applied?
Since zirconium oxide is white and, therefore, shows a poor contrast
to tooth-coloured and/or white powders, the IPS e.max ZirLiner was
given an identification colour to render its application more simple
and efficient. The IPS e.max Ceram ZirLiner consists of a very fine
powder and appears somewhat thick due to the dense packing of
the grains. Make sure that the material is applied in an even,
greenish coat. If the shade is too pale, the layer is too thin. After
firing, however, the ZirLiner demonstrates a layer thickness of
approximately 0.1 mm.
How thick should the wax-up be?
The wax-up should be at least 0.7 mm thick all over. If the wax is
not at least this thick, the restoration may not be completely
covered with the pressed ceramic and deviations in the shade may
occur.
Can IPS Empress Universal Shades, Stains and Glaze be used
with IPS e.max ZirPress?
IPS Empress Universal Shades, Stains and Glaze have been specially
developed for the IPS Empress system. Consequently, they cannot
be used with IPS e.max products.
Can IPS e.max Alox plungers also be used for IPS Empress?
IPS e.max Alox plungers are exclusively for the IPS e.max System and
the corresponding investment ring system specifically developed for
this purpose. Since the diameter has been increased, the Alox
plunger would not fit into the IPS Empress investment ring system.
Can the IPS e.max Alox Plunger Separator also be used for
other pressed ceramics, such as IPS Empress Esthetic?
The IPS e.max 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 other press furnaces be used to press IPS e.max ZirPress
ingots?
IPS e.max ZirPress is specifically coordinated with the Ivoclar
Vivadent press furnaces (EP 500, EP 600, and EP 600 Combi). If
other press furnaces are used, the parameters have to be adjusted
accordingly by the user.
Can IPS e.max ZirPress restorations also be conventionally
cemented?
IPS e.max ZirPress restorations may be either adhesively or
conventionally cemented. For conventional cementation, however,
an appropriately retentive preparation design must be observed. If
this is not possible, adhesive cementation, e.g. with Multilink®
should be used. Vivaglass® CEM is available for conventional
cementation. We advise against the use of traditional phosphate
cements, since they negatively influence the light transmission
through the all-ceramic and compromise the aesthetic appearance
of the all-ceramic restorations.

The shading and opacity control of the IPS e.max ZirPress ingots is based on a newly
developed, translucency/opacity concept. The system is flexibly organized and can be
used with both A–D and Chromascop shades. The individual levels of the concept are
determined by indications and application. The individual opacity and translucency
levels are distinguished by means of a colour code.
I N G O T C O N C E P T
Low Translucency
IPS e.max ZirPress MO (Medium Opacity)
These ingots are available in the nine most popular A–D shades as well as in the
lightest Chromascop Bleach shade. Because of their opacity, they are ideal for
situations in which a dentin core is pressed onto IPS e.max ZirCAD frameworks. The
combination of the fluorescence of the IPS e.max Ceram ZirLiner and the fluorapatite
crystals of the ingots produces an outstanding bond and an ideal shade base. The
ingots exhibit natural dentin-like fluorescence. After the ceramic has been pressed
onto the framework, the incisal third of the restoration is characterized with ease
using the IPS e.max Ceram Incisal and Impulse materials. As a result, little effort is
required to create highly aesthetic zirconium oxide-reinforced restorations using the
proven cut-back technique.
IPS e.max ZirPress LT (Low Translucency)
These ingots are available in the nine most popular A-D shades as well as the lightest
Chromascop Bleach shade. Because of their translucency, they are ideal for pressing a
fully anatomic ceramic layer onto IPS e.max ZirCAD frameworks. In combination with
the fluorescent IPS e.max Ceram ZirLiners, an outstanding bond to the framework is
created. The IPS e.max Ceram Intensive ZirLiners are used to apply characterizations
before the ceramic material is pressed onto the framework. Therefore, the restorations
obtain a natural-looking effect of depth. Furthermore, the ingots exhibit lifelike
fluorescence in the incisal aera. The restorations are subsequently characterized with
IPS e.max Ceram Shades and Essence materials. If necessary, contacts or similar
features can be built up with IPS e.max Ceram layering materials.

IPS e.max Alox Plunger The ceramic ingot, in its softened state, is pressed into the hollow
space in the investment ring by means of the IPS e.max Alox plunger.
It features a larger diameter and is slightly shorter than the existing
IPS Empress Alox plunger and is thus only suitable for the IPS e.max
investment ring system. Both ends of the Alox plunger are rounded,
which makes both sides suitable for pressing. In this respect, the
new plunger is different from the existing IPS Empress press
plungers.
Delivery form:
IPS e.max Alox Plunger
– 2 IPS e.max Alox Plungers
IPS e.max Alox Plunger Separator The IPS e.max Alox Plunger Separator prevents the ingot from
sticking to the Alox plunger during pressing and cooling in the
investment ring. The cold Alox plunger is inserted into the recess
and rotated. The powder adheres to the surface and thus forms a
separating layer. A very small amount of Separator is sufficient. The
cold, prepared Alox plunger is subsequently inserted into the pre-
heated investment ring immediately before pressing.

Chromascop
The Chromascop shade guide provides the shade standard
for Ivoclar Vivadent products. The individual shades of the
Chromascop are logically arranged and therefore allow shades
to be determined accurately and efficiently. The 20 shades are
divided into five shade groups. In addition, the Chromascop Bleach
shade group comprises four very light shades. Once the basic hue
has been established, the most suitable shade is chosen from within
the shade group. All superfluous effects (eg cervical and translucent
areas, severe discolourations in the incisal area and dentin as well as
superficial characterizations) have been left out, making the selection of
the proper shade much easier.
IPS Natural Die Material Shade Guide
In order to facilitate the reproduction of the tooth shade, dentists have the
possibility of communicating the shade of the preparation of the given
clinical situation to the dental laboratory using the IPS Natural Die
Material shade guide. In this way, the fabrication of all-ceramic
restorations is facilitated and a patient's individual characteristics
can be taken into consideration.

Successful results can only be achieved with IPS e.max ZirPress if the guidelines and framework thicknesses of
IPS e.max ZirCAD are strictly observed.
Single crowns and 3-unit bridges
Evenly reduce the anatomical shape and observe the stipulated minimum thicknesses. Prepare a circular shoulder with
rounded inner edges or chamfer with an angle of approx. 10° - 30 °. The width of the circular shoulder/chamfer is approx.
1 mm. Reduction of the crown third – incisal or occlusal by about 1.5 mm. For anterior crowns, the labial and palatal/
lingual part of the tooth should be reduced by about approx. 1.2 mm. The incisal edge of the preparation should be at
least 1 mm (milling tool geometry) in order to permit optimum milling of the incisal area during CAD/CAM processing.

The framework design is the key to the success of durable all-ceramic restorations. The
more attention given to framework design, the better the final results and the
clinical success will turn out to be. The following basic guidelines have to be observed:
– The framework material is the high-strength component of your restoration
and should, therefore, be designed in such a way that it supports the shape
of the restoration and the cusps. Reinforcements and supports have to be
built up using the corresponding tools of the respective software.
– In large preparations, the excess in available space must be compensated by
the design of the framework and not by the layering material.
– If possible, the connector design should be extended in the vertical direction,
rather than in the sagittal or horizontal direction.
– It is not always possible to establish the necessary connector dimensions with
regard to the sagittal (linguo-vestibular) region. In these cases, the connector
dimensions must always be increased in the vertical (inciso-cervical) direction.
– Reducing the framework thickness is always related to a reduction in
strength.
– The integrated parameters in the software are basic recommendations. Depending
of the overall thickness of the restoration it can be necessary to adjust the
parameters.

For the cementation of the IPS e.max restorations, you may select between the tried-and-tested adhesive
luting composites and cements from the coordinated assortment of Ivoclar Vivadent. Adhesive
cementation achieves a sound bond between the preparation and the cementation material, while
conventional cementation requires a retentive preparation to ensure the durability of the IPS e.max
restorations.

Preparation of the framework and application of ZirLiner
The sintered IPS e.max ZirCAD framework is tried in on the model. The margins can be trimmed up to the inner edge of
the chamfer or shoulder preparation to make room for the pressed ceramic shoulder. After the adjustments have been
made, the framework must still exhibit the required minimum thickness. The following procedure should be followed:
– Before the veneering procedure, the framework must be cleaned under running water
or with steam.
– The framework must not be blasted with Al2O3, as this would damage its surface.
– Before contouring begins, IPS e.max Ceram ZirLiner must be applied to generate a
strong bond and create the effect that the shade and fluorescence of the restoration
come from deep within.
– If a ceramic material is directly pressed onto ZirCAD frameworks without using ZirLiner,
the bond created is very weak and cracks and delamination are likely to occur.
– Subsequently, IPS e.max Ceram ZirLiner in the desired shade is mixed to a creamy
consistency with the matching liquid.
– If another type of consistency is desired, IPS e.max Ceram Build-Up Liquids (allround
and soft) as well as the IPS e.max Glaze and Stain Liquids (allround and longlife) can be
used. The liquids may also be mixed with each other in the required ratio.
– IPS e.max ZirLiner is applied until it fully covers the framework. Care must be taken at
the margins. If necessary, the restoration may be vibrated until an even greenish colour
is achieved. If the colour is too pale, the increment is too thin.
– For areas requiring stronger colours, four IPS e.max Ceram Intensive ZirLiners (yellow,
orange, brown, incisal) are available.
– Next, the applied ZirLiner is briefly left to dry and then fired.
– IPS e.max Ceram ZirLiner should demonstrate a thickness of 0.1 mm after firing.

Wax-up
The wax-up must be fabricated using wax that fires without leaving any residue. The cut-back technique is conducted as
follows:
– The stone die is isolated with a conventional plaster-wax separator
– Calipers are used to measure and record the thickness of the ZirCAD framework at various points.
– The ZirCAD framework onto which IPS e.max Ceram ZirLiner has been fired is weighed and the weight recorded. Once
the wax-up has been made, this data is used to determine the wax weight.
– Subsequently, the framework is secured in the correct position on the die. The margins are attached with wax first.
– A fully anatomic wax-up is created in the usual way and a silicone matrix is made.
– The waxed-up framework can be reduced at this stage. Alternatively, the framework can be pressed to full contour and
then reduced by grinding.
– If the wax-up is reduced, the incisal layer has to be trimmed selectively. A wax thickness of 0.7 mm must be observed to
avoid incomplete press results.

Sprueing
Always place the sprues in the direction of flow of the ceramic and at the thickest part of the wax-up in order to achieve
unimpeded flow of the viscous ceramic material. The 100 g or 200 g investment ring base is selected depending on the
number of objects to be invested. Bridges must be pressed using the 200 g investment ring system. The following sprueing
guidelines must be observed:

Investing
Investing is carried out with either IPS PressVEST (e.g. over night) or IPS PressVEST Speed (during the
day). The corresponding IPS silicone ring with matching ring gauge is used for that purpose. We
recommend the following procedure to determine the accurate wax weight:
– Weigh the ring base (seal the opening of the ring base with wax).
– Position the objects to be pressed on the ring base and attach them with wax. Weigh again.
– The wax weight is calculated by subtracting the weight of the ring base and the ZirCAD framework
from the total weight.
Small Ingot 2 small ingots
Wax weight up to max. 0.75 g up to max 2 g
Investment Ring System 100 g and 200 g 200 g only
Please refer to the Instructions for use of the corresponding investment material regarding the detailed
processing parameters.
– Do not apply a debubblizer to the wax objects.
– Mix investment material. The investment material contains quartz powder. Therefore, the inhalation of
dust must be avoided.
– Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax
margins are not damaged.
– Carefully position the IPS Silicone Ring on the investment ring base without damaging the wax
objects. The IPS Silicone Ring must sit flush on the investment ring base.
– Subsequently, carefully fill the investment ring with investment material up to the marking and
position the ring gauge with a hinged movement.
– Allow the investment material to set without manipulating the investment ring.
– Do not use IPS PressVEST for investment over the weekend to prevent crystallization.
Use the IPS Silicone Ring for investment.
Fill investment ring up to the marking and position the ring gauge with a hinged movement.
23
Preheating
After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the
investment ring is prepared for preheating as follows:
– Remove the ring gauge and ring base with a turning movement,
– Carefully push the investment ring out of the IPS Silicone Ring.
– Remove rough spots on the bottom surface of the investment ring with a plaster knife and check the 90° angle.
– Investment material residue must not enter the sprues. Blow into the sprues if necessary.
– If several investment rings are preheated together, mark them with the respective ingot shade.

Calibration
The furnace must be regularly calibrated to achieve optimum press results. Calibrate the EP500 with the
Temperature Checking Set 2 and the EP600 with the Automatic Temperature Checking Set 1.
EP 500
1. Switch on the EP500 and allow the furnace to heat up to the stand-by-temperature of 700 °C/
1292 °F. Hold this temperature for at least 30 minutes.
2. Select a program for the staining technique T=1075 °C/1967 °F. Run the program with the furnace
empty. After activation of the holding time H=20 min., which the EP500 does automatically,
interrupt the program after 15 minutes (set timer) by pressing the STOP key twice.
If you fail to interrupt the program, the ER16 error message appears. Rectify this error by following
the instructions given on the corresponding list of error messages. Allow the furnace to cool until
the stand-by-temperature of 700 °C/1292 °F has been reached with the furnace head closed. Hold
this temperature for at least 30 minutes.
3. Place the calibration set on the honey-combed firing tray in order to ensure the appropriate height
(temperature range) in the furnace.
4. Conduct the calibration using the Temperature Checking Set 2.
EP 600
1. Place the melting sample in the ceramic base.
2. Tighten the contact pin to secure the melting sample.
Important: Do not use tweezers or tongs. Apply slight pressure to secure the melting sample in
place.
3. Select the calibration program in the 'Miscellaneous' menu. The furnace head opens.
4. Remove the firing plate from the furnace and place it on the cooling plate using the firing tongs.
5. Place the calibration tray in the holes for the Automatic Temperature Checking Set ATK 1 in the
stone lining.
6. Slightly press the calibration tray into place with the firing tongs until you feel it click into place.
7. Start the calibration program
8. Once the program is completed, remove the calibration sample from the furnace using the tongs
and allow it to cool.

Pressing
Before the preheating cycle for the investment ring has ended, the following preparations for pressing must
be carried out:
– Provide a cold IPS e.max Alox Plunger and a cold IPS e.max ZirPress ingot in the desired shade.
– After that, dip the cold IPS e.max Alox plunger into the opening of the IPS e.max Alox Plunger Separator
and keep ready for use.
– Select the press program for IPS e.max ZirPress.
Once the preheating cycle has been completed, remove the investment ring from the preheating furnace
and proceed as follows. Make sure that you take no more than 1 minute for these steps to prevent the
investment ring from cooling down too much.
– Insert the cold IPS e.max ZirPress ingot into the hot investment ring.
– Insert the ingot with the rounded, non-imprinted side into the investment ring. The imprinted side should
face upward to double-check the ingot shade.
– Place the powder-coated cold IPS e.max Alox plunger into the hot investment ring.
– Place the completed investment ring at the center of the hot press furnace using the investment tongs.
– Press START to start the selected program.

Divesting
After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks.
These cracks developed (immediately around the Alox plunger) during cooling as a result of the different
CTEs of the various materials (Alox plunger, investment material, and pressed materials). They do not
compromise the press result.
Divest the investment ring as follows:
– Mark the length of the Alox plunger on the cooled investment ring.
– Separate the investment ring using a separating disk. This predetermined breaking point enables reliable
separation of the Alox plunger and the ceramic material.
– Break the investment ring at the predetermined breaking point using a plaster knife.
– Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure.
– Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure.
– Do not use Al2O3 for rough or fine divestment
– When divesting the object, blast from the direction indicated in the schematic below and observe the
appropriate distance in order not to damage the object margins.
– Any ceramic residue on the Alox plunger is removed with Al2O3 (type 100 microns).
Separate the investment ring using a separating disk and break it at the predetermined breaking point
Mark the length of the Alox plunger
Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure until the restoration is visible.Fine divestment is conducted at 2 bar (30 psi) pressure.
28
Removing the reaction layer
After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max
Press Invex Liquid followed by blasting. The procedure is carried out as follows:
– Pour the Invex Liquid into a plastic cup.
– Immerse the pressed objects into the Invex Liquid and clean in an ultrasonic cleaner for at least
5 minutes and a maximum of 10 minutes. Make sure that the objects are completely covered with
Invex Liquid.
– Subsequently clean the object under running water and blow dry.
– Carefully remove the white reaction layer using Al2O3 Type 100 at 1–2 bar (15–30 psi) pressure.
– Make sure that the reaction layer is completely removed, both on the cavity side and on the outer side
of the object (repeat the procedure, if necessary).
– If the reaction layer is not entirely removed, bubbles may develop, which may lead to bonding
problems or even cracks in the layering ceramic.
– Replace the Invex Liquid after approximately 20 uses or after sedimentation of the liquid.
Warnings
– The Invex Liquid contains < 1 % hydrofluoric acid.
– It is harmful when inhaled, swallowed, and when it comes into contact with the skin.
Furthermore, it is corrosive.
– Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet).
– If the material comes into contact with the eyes, immediately rinse with copious amounts of water
and see a physician immediately.
– If the material comes into contact with the skin, immediately clean with soap and copious amounts
of water.
– Use suitable protective clothing, gloves, and goggles when working.
– In case of an accident or physical discomfort, see a physician immediately (bring the Invex label, if
possible).
Disposal
– Neutralize the Invex Liquid
– Neutralize the diluted solution by adding lime or baking soda and letting it react for 5 minutes.
– After the reaction time, pour the neutralized solution into the sink, flushing it with running water.
Remove the reaction layer with Invex and Al2O3 at 1–2 bar (15–30 psi) pressure.
29
Finishing
It is of critical importance to use the correct grinding instruments for finishing and adjusting glass-ceramics. If unsuitable
grinding instruments are used chipping of the edges and local overheating may occur (please see the corresponding
recommendations from Ivoclar Vivadent).
The following procedure is recommended to finish IPS e.max ZirPress frameworks:
– Wet the area to be ground and use a fine diamond disk to cut the sprues. Try the
restoration in on the model.
– Prevent overheating of the ceramic material. Low speed and light pressure is
recommended. Please observe the corresponding instructions of the manufacturer.
– Smooth out the attachment points of the sprues.
– Do not 'post-separate' the bridge framework using separating disks, since this may
result in undesired predetermined breaking points, which will subsequently compromise
the stability of the all-ceramic restoration.
– If a fully anatomic wax-up was pressed, the restoration is now cut back. Cut back the
restoration to make room for the application of the subsequent layers of Incisal and
Impulse materials. Make sure that the minimum thickness of the restoration is
maintained during the cut-back procedure.
– If a reduced version of the restoration was waxed-up, only the surface has to be slightly
adjusted. Make sure that the minimum thickness of 0.6 mm is maintained to avoid
irregularities in the shading.
– Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or
with steam before applying the veneering material.
– Some blasting machines may require different pressure settings to accomplish this
procedure.
Cut the sprues using a fine diamond disk and place the framework on the die. Use low speed and light pressure …

Optional
Die fabrication with IPS Natural Die Material
The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. A control die is fabricated using the
shade information provided by the dentist (shade determination). This control die represents the optimum basis for a
true-to-nature shade reproduction of the given oral situation.
– Coat the inner surfaces of the ceramic restorations with IPS Natural Die Material Separator and allow it to react for a
short time.
– Apply die IPS Natural Die Material in the corresponding shade to the inner surfaces of the restoration using the
IPS Condenser and adapt so that the entire inner surface is coated and filled.
– Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the
holder. Make sure that the Die Material is well adapted to the restoration margins and that no gaps are present.
– Polymerize the IPS Natural Die Material die with a commercial polymerization light, e.g. Lumamat 100, for 60 seconds.
– After polymerization, the die can be finished and or smoothed, if required.
Veneering with IPS e.max Ceram
The following paragraphs will explain the most important veneering steps.
Detailed information about the nano-fluorapatite ceramic and its processing
are contained in the IPS e.max Ceram Instructions for Use.
Firing of zirconium oxide-supported restorations
– Several units (eg multi-unit bridges with bulky pontics) in the furnace impede even and thorough heating of the
individual units.
– Heat penetration in the firing chamber depends on the type of furnace and the size of the firing chamber.
– To achieve adequate heating of the individual restorations the heating rate should be lowered by 5–10 ºC (41–50 °F) as
well as the holding time should be extended by 30 seconds.
– The parameters listed in the Instructions for Use apply to Ivoclar Vivadent furnaces (temperature tolerance ± 10 ºC/50 °F).
– If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary.

it must not be contaminated in any way. Conduct the foundation firing using Incisal or Transpa (clear, neutral)
materials or with IPS e.max Ceram Shades, Incisal Shades and Essence materials. The IPS e.max Ceram ZirLiner
must not be used. Please follow the instructions provided below:
– Use the IPS e.max Ceram Build-up Liquids (allround and soft) to mix the Incisal, Transpa and Impulse
materials. If a mouldable consistency is preferred, the IPS e.max Ceram Glaze and Stain
Liquids (allround and longlife) can be used. Apply a thin, but complete coat of

Wash firing (foundation firing) characterization
Intensively characterized areas may be designed with IPS e.max Ceram Essence. These materials are ideally
suited to apply individualized characterizations.
Layering materials must not be applied on unfired wash layers (powders and pastes), since this will result in
a delamination of the layering ceramic. The wash (foundation) must be fired before the actual layering
procedure is started.

Finishing and preparation for the Stain and Glaze firing
The surface must be finished and polished as follows before the stains and glaze firing:
– Use finishing diamonds to achieve a natural shape and surface of the restoration.
– Areas that are not covered with the layering ceramic must be smoothed with silicone wheels and prepolished to obtain
an even gloss on the surface after glaze firing.
Create a natural shape and surface with finishing diamonds.
Smooth and prepolish pressed ceramic areas.
34
Stain and Glaze firing
Stain firing is conducted with Essence and Shade materials, while Glaze firing is carried out with Glaze powder or paste
according to the following steps. Depending on the situation, the firings may be conducted together or separately. The
firing parameters are identical.
– Apply a thicker layer of Glaze to the areas that are not covered with the layering ceramic than to those areas which are
covered with the ceramic. This helps to achieve an even gloss.
– If a silky-matte finish is achieved on the pressed and layering ceramic surfaces during prepolishing, the glaze has to be
applied only to the pressed ceramic areas. The layering ceramic is not over-glazed and left with its natural sheen.
– The fissures and cusps are individually characterized with the Essence materials.
Apply Glaze more thickly on the pressed ceramic areas.

Preparation of the framework and application of ZirLiner
The sintered IPS e.max ZirCAD framework is tried in on the model. The margins can be trimmed up to the inner edge of
the chamfer or shoulder preparation to make room for the pressed ceramic shoulder. After the adjustments have been
made, the framework must still exhibit the required thickness. The following procedure should be followed:
– Before veneering, the framework must be cleaned under running water or with steam.
– The framework must not be blasted with Al2O3, as this would damage its surface.
– IPS e.max Ceram ZirLiner must always be applied prior to contouring in order to achieve
a sound bond, as well as an in-depth shade effect and fluorescence.
– Direct pressing on ZirCAD frameworks without using IPS e.max Ceram ZirLiner results in
a poor bond and may lead to delamination.
– Mix the IPS e.max Ceram ZirLiner in the corresponding shade with the respective liquid
to a creamy consistency.
– If a different consistency is desired, the IPS e.max Ceram Build-Up Liquids (allround
and soft) and the IPS e.max Ceram Glaze and Stain Liquids (allround and longlife) may
be used. The liquids may also be mixed with each other at any mixing ratio.
– Apply ZirLiner on the entire framework, pay special attention to the margins. If
required, the restoration may be vibrated until an even, greenish colour effect is
achieved. If the colour appears too pale, the layer is too thin.
– For more intensively shaded areas, 4 IPS e.max Ceram Intensive ZirLiners (yellow,
orange, brown, incisal) are available.
– After that, the applied ZirLiner is briefly dried and fired.
– The IPS e.max Ceram ZirLiner should have a layer thickness of approximately
0.1 mm after firing

Wax-up
The wax-up must be fabricated using wax that fires without leaving any residue. The cut-back technique is conducted as
follows:
– The stone die is isolated with a conventional plaster-wax separator
– Calipers are used to measure and record the thickness of the ZirCAD framework at various points.
– The ZirCAD framework onto which IPS e.max Ceram ZirLiner has been fired is weighed and the weight recorded. Once
the wax-up has been made, this data is used to determine the wax weight.
– Subsequently, the framework is secured in the correct position on the die. The margins are attached with wax first.
– A fully anatomic wax-up is created in the usual way and a silicone matrix is made.
– The waxed-up framework can be reduced at this stage. Alternatively, the framework can be pressed to full contour and
then reduced by grinding.
– If the wax-up is reduced, the incisal layer has to be trimmed selectively. A wax thickness of 0.7 mm must be observed to
avoid incomplete press results.

Sprueing
Always place the sprues in the direction of flow of the ceramic and at the thickest part of the wax up in order to achieve
unimpeded flow of the viscous ceramic material. The 100 g or 200 g investment ring base is selected depending on the
number of objects to be invested. Bridges must be pressed using the 200 g investment ring system. The following sprueing
guidelines must be observed:
Sprueing is carried out on the IPS e.max investment ring base. Sprues are attached in the direction of flow of the ceramic and always at the thickest part of the restorations

Preheating
After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the
investment ring is prepared for preheating as follows:
– Remove the ring gauge and ring base with a turning movement.
– Carefully push the investment ring out of the IPS Silicone Ring.
– Remove rough spots on the bottom surface of the investment ring with a plaster knife and check the 90° angle.
– Investment material residue must not enter the sprues. Blow into the sprues if necessary.
– If several investment rings are preheated together, mark them with the respective ingot shade.
In order to ensure smooth working procedures in the laboratory on a daily basis, impeccable functioning of the infrastructure and the
preheating furnaces is essential. This includes their maintenance, cleaning with a vacuum cleaner in a cool state as well as regular checks
of the temperature controls and heating elements, etc, by the manufacturer.
Place the investment ring towards the rear wall, tipped with the openingfacing down.
Do not preheat IPS e.max ZirPress ingots and Alox plunger.
Calibration
It is important to note that press furnaces must be calibrated on a regular basis. For information please see page 24.

Pressing
Before the preheating cycle for the investment ring has ended, the following preparations for pressing must
be carried out:
– Provide a cold IPS e.max Alox Plunger and a cold IPS e.max ZirPress ingot in the desired shade.
– After that, dip the cold IPS e.max Alox plunger into the opening of the IPS e.max Alox Plunger Separator
and keep ready for use.
– Select the press program for IPS e.max ZirPress.
Once the preheating cycle has been completed, remove the investment ring from the preheating furnace
and proceed as follows. Make sure that you take no more than 1 minute for these steps to prevent the
investment ring from cooling down too much.
– Insert the cold IPS e.max ZirPress ingot into the hot investment ring.
– Insert the ingot with the rounded, non-imprinted side into the investment ring. The imprinted side should
face upward to double-check the ingot shade.
– Place the powder-coated cold IPS e.max Alox plunger into the hot investment ring.
– Place the completed investment ring at the center of the hot press furnace using the investment tongs.
– Press START to start the selected program.
Insert the cold IPS e.max ZirPress ingot into the hot investment ring with the shade designation facing upward.

Divesting
After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks.
These cracks developed (immediately around the Alox plunger) during cooling as a result of the different
CTEs of the various materials (Alox plunger, investment material, and pressed materials). They do not
compromise the press result.
Divest the investment ring as follows:
– Mark the length of the Alox plunger on the cooled investment ring.
– Separate the investment ring using a separating disk. This predetermined breaking point enables reliable
separation of the Alox plunger and the ceramic material.
– Break the investment ring at the predetermined breaking point using a plaster knife.
– Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure.
– Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure.
– Do not use Al2O3 for rough or fine divestment
– When divesting the object, blast from the direction indicated in the schematic below and observe the
appropriate distance in order not to damage the object margins.
– Any ceramic residue on the Alox plunger is removed with Al2O3 (type 100 microns).Mark the length of the Alox plunger
Separate the investment ring using a separating disk and break it at the predetermined breaking point
Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure until the restoration is visible.Fine divestment is conducted at 2 bar (30 psi) pressure.
43
Removing the reaction layer
After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max
Press Invex Liquid followed by blasting. The procedure is carried out as follows:
– Pour the Invex Liquid into a plastic cup.
– Immerse the pressed objects into the Invex Liquid and clean in an ultrasonic cleaner for at least
5 minutes and a maximum of 10 minutes. Make sure that the objects are completely covered with
Invex Liquid.
– Subsequently clean the object under running water and blow dry.
– Carefully remove the white reaction layer using Al2O3 Type 100 at 1–2 bar (15–30 psi) pressure.
– Make sure that the reaction layer is completely removed, both on the cavity side and on the outer side
of the object (repeat the procedure, if necessary).
– If the reaction layer is not entirely removed, bubbles may develop, which may lead to bonding
problems or even cracks in the layering ceramic.
– Replace the Invex Liquid after approximately 20 uses or after sedimentation of the liquid.
Remove the reaction layer with Invex and Al2O3 at 1–2 bar (15–30 psi) pressure.
Warnings
– The Invex Liquid contains < 1 % hydrofluoric acid.
– It is harmful when inhaled, swallowed, and when it comes into contact with the skin.
Furthermore, it is corrosive.
– Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet).
– If the material comes into contact with the eyes, immediately rinse with copious amounts of water
and see a physician immediately.
– If the material comes into contact with the skin, immediately clean with soap and copious amounts
of water.
– Use suitable protective clothing, gloves, and goggles when working.
– In case of an accident or physical discomfort, see a physician immediately (bring the Invex label, if
possible).
Disposal
– Neutralize the Invex Liquid
– Neutralize the diluted solution by adding lime or baking soda and letting it react for 5 minutes.
– After the reaction time, pour the neutralized solution into the sink, flushing it with running water.
44
Finishing
It is of critical importance to use the correct grinding instruments for finishing and adjusting glass-
ceramics. If unsuitable grinding instruments are used chipping of the edges and local overheating may
occur (please see the corresponding recommendations from Ivoclar Vivadent).
The following procedure is recommended to finish IPS e.max ZirPress frameworks:
– Wet the area to be ground and use a fine diamond disk to cut the sprues. Try the restoration in on
the model.
– Prevent overheating of the ceramic material. Low speed and light pressure is recommended. Please
observe the corresponding instructions of the manufacturer.
– Smooth out the attachment points of the sprues.
– Do not 'post-separate' the bridge framework using separating disks, since this may result in undesired
predetermined breaking points, which will subsequently compromise the stability of the all-ceramic
restoration.
– Finish the restoration with diamonds to achieve a natural-looking shape and surface.
– Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or with steam prior
to staining and characterizing.
– Some blasting machines may require different pressure settings to accomplish this procedure.
Optional
Die fabrication with IPS Natural Die Material
The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. A control die is fabricated using the
shade information provided by the dentist (shade determination). This control die represents the optimum basis for a
true-to-nature shade reproduction of the given oral situation.
– Coat the inner surfaces of the ceramic restorations with IPS Natural Die Material Separator and allow it to react for a
short time.
– Apply die IPS Natural Die Material in the corresponding shade to the inner surfaces of the restoration using the
IPS Condenser and adapt so that the entire inner surface is coated and filled.
– Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the
holder. Make sure that the Die Material is well adapted to the restoration margins and that no gaps are present.
– Polymerize the IPS Natural Die Material die with a commercial polymerization light, e.g. Lumamat 100, for 60 seconds.
– After polymerization, the die can be finished and or smoothed, if required.
Use low rpms and light pressure to grind away sprue attachment points and achieve a natural-looking shape and surface.
Remove sprues with a thin diamond disk and try the restoration in on the model
45
Firing of zirconium oxide-supported restorations
– Several units (eg multi-unit bridges with bulky pontics) in the furnace impede even and thorough heating of the
individual units.
– Heat penetration in the firing chamber depends on the type of furnace and the size of the firing chamber.
– To achieve adequate heating of the individual restorations the heating rate should be lowered by 5–10 ºC (41–50 °F)
as well as the holding time should be extended by 30 seconds.
– The parameters listed in the Instructions for Use apply to Ivoclar Vivadent furnaces (temperature tolerance ± 10 ºC/50 °F).
– If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary.
Staining, characterizing and glazing with IPS e.max Ceram
The most important staining and characterization steps are described below. Detailed information about the nano-
fluorapatite ceramic and its processing are contained in the IPS e.max Ceram Instructions for Use.
46
Stain and characterization firing
Before the stain and characterization firing cycle is conducted, the restoration must be free from dirt and oil. After
cleaning, the restoration must not be contaminated in any way. The procedure is conducted as follows:
– To promote wetting of the stains, IPS e.max Ceram Glaze and Stain Liquid (longlife) can be lightly painted onto the
surface.
– Mix the paste or powder with the IPS e.max Glaze and Stain Liquid (allround and longlife) until the desired
consistency is achieved.
– If stronger shades are desired, these are created by repeated staining rather than by applying shades too thickly.
– IPS e.max Ceram Shade Incisal is used to imitate the appearance of the incisal edge and the translucency in the incisal
third.
– Fissures and cusps are individually characterized with Essence materials.

recommended:
– Mix the required Glaze to the desired consistency with the IPS e.max Glaze and
Stain Liquids (allround and longlife).
– Evenly apply the glaze on the entire restoration.
– If a higher fluorescence is desired in the cervical region, fluorescent Glaze materials
(paste or powder) can be used in this area.

Conditioning of the ceramic surface in preparation for cementation is decisive for generating a sound bond between the
luting material and the all-ceramic restoration.
In the combination of IPS e.max ZirCAD and IPS e.max ZirPress, the conditioning measures must be conducted according
to the indications. The following points must be observed:
– High-strength zirconium oxide ceramics are generally not etched with hydrofluoric acid (IPS Ceramic Etching Gel), as it
does not produce an etching pattern.
– Zirconium oxide-supported restorations may be blasted at max. 1 bar (15 psi) pressure to clean the surfaces prior to
cementation.
– If ceramic materials have been pressed onto inlay-retained bridges, the glass-ceramic to which the other materials have
been pressed must be etched with hydrofluoric acid (IPS Ceramic Etching Gel) and silanated and seated according to
adhesive luting methods.
For the cementation of IPS e.max ZirPress restorations, you may choose between the tried-and-tested luting composites
and cements of the coordinated assortment from Ivoclar Vivadent.
Please observe the IPS Ceramic Etching Gel Instructions for Use.
