ALL YOU NEED
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 allceramic. 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.

USAGE
IPS e.max Press is a lithium disilicate
glass-ceramic ingot for the PRESS
technology. The manufacturing
process produces homogeneous
ingots in various degrees of
opacity having a flexural strength
of 400 MPa.
IPS e.max Press ingots are therefore
the pressed ceramic ingots featuring the highest strength. The
ingots are pressed in Ivoclar Vivadent press furnaces and produce
accurately fitting restorations. Compared to IPS Empress® ingots,
IPS e.max Press are larger in diameter, i.e. more volume, which
allows more restorations to be produced per press cycle. This
increases the economic efficiency and working speed. The pressed,
tooth-coloured and highly aesthetic frameworks are then veneered
using IPS e.max Ceram.

QUESTIONS AND ANSWERS
Is IPS e.max Press suitable for the fabrication
of 3-unit bridges up to the first molar as the
abutment?
Can other press furnaces be used to press
IPS e.max Press ingots?
IPS e.max Press 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.
The material can be used for 3-unit bridges from
the first premolar to the first molar as abutment.
However, the molar must be given a fully anatomical design and connector dimensions of
20 mm2 (IPS Connector C6) must be observed.
May IPS e.max Press frameworks be blasted
using Al2O3 after completion (on the cavity
side)?
Is IPS e.max Press suitable for the fabrication
of fully anatomical crowns?
IPS e.max Press can be used for fully anatomical
crowns. However, the opacity of the ingots somewhat limits the aesthetic results. This fact must be
considered during the fabrication.
IPS e.max Press restorations must not be sand
blasted prior to cementation, since this would
damage the ceramic surface and alter its
properties. Prepare the internal surfaces by
etching.
Is IPS e.max Press suitable to press-over
Captek or other metal frameworks?
May IPS e.max Ceram Margin materials also
be used for IPS e.max Press?
IPS e.max Press cannot be pressed-over Captek
and other metal frameworks, since the
corresponding CTE values are not coordinated
with each other.
IPS e.max Ceram Margin materials must not be
used on the glass-ceramic materials (IPS e.max
Press and CAD), since the firing temperatures are
too high and the reduction for the shoulder
would weaken the restoration.
Can IPS Empress Universal Shades, Stains and
Glaze be used for IPS e.max Press?
Can IPS e.max Press restorations also be
conventionally cemented?
IPS Empress Universal Shades, Stains, and Glaze
have been especially developed for the IPS
Empress System and thus cannot be used for
IPS e.max products.
IPS e.max Press 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 Variolink® II and 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.
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.

INGOT CONCEPT
The shading and opacity control of the IPS e.max Press 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.

HO
IPS e.max Press MO (Medium Opacity)
Because of their opacity, ingots in the shades MO 0 – MO 4 are ideally suitable for the
fabrication of frameworks on vital or slightly discoloured preparations and provide the
ideal basis for restorations in A-D and Chromascop shades with a natural appearance.
The ingots are shaded according to specific group shades. The fluorescence of the
ingots decreases with the intensity of the shading.
The IPS e.max Press HO (High Opacity) ingots are available in one shade and, due
to their higher opacity, are ideal for the fabrication of frameworks on devitalized or
severely discoloured preparations, as well as to partially cover metal core build-ups.
The high opacity adequately masks the substructure and enables the fabrication of
lifelike restorations even in situations with difficult or very dark preparations.

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 preheated investment ring immediately before pressing.

IPS e.max Investment Ring System
The IPS e.max Investment Ring System is used to sprue the
contoured restorations. The base has been enlarged so that the
IPS Silicone Ring optimally fits onto the base. The larger IPS e.max
investment ring base thus substantially differs from the IPS Empress
investment ring base, which prevents the two bases from being
confused.

S H A D E D E T E R M I N AT I O N
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.
IPS e.max Press Shade Guide
IPS e.max Press shade guide makes it possible for the dentist to choose the shade of
the ingot to be used for the case. The shade tabs show the shade of the ingot after
pressing.

Successful working with IPS e.max Press can only be ensured if the following guidelines and layer thicknesses are observed.
Crowns
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 areas – by approx. 2 mm. For anterior crowns, the labial and
palatal/lingual part of the tooth should be reduced by approx. 1.5 mm.

Bridges
The maximum acceptable bridge pontic width varies from patient to patient. It depends on the position, size, and state of
the teeth, as well as the position of the abutments within the tooth arch. The measurements to determine the bridge
pontic width should be done on the unprepared tooth.
– In the anterior region (up to the canine), the bridge pontic width should not exceed 11 mm
– In the premolar region (from the canine up to the 2nd premolar), the bridge pontic width should not exceed 9 mm

FRAMEWORK DESIGN CRITERIA
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 must, therefore, always make up at least 50 % of the total layer
thickness of the restoration.
– 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.
– Especially in anterior bridges, 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 (incisocervical) direction.
– The translucency of the IPS e.max Press MO ingots is similar to that of natural
teeth and has been coordinated with the stipulated layer thicknesses.
– A reduction of the framework thickness is always related to a reduction in
strength, in value and in shade stability of the restoration.
– If only limited space is available, non-aesthetic areas (e.g. palatal or occlusal
surfaces) do not necessarily have to be covered with layering material. In such
cases, the corresponding areas of the framework are designed in their fully
anatomical shape and subsequently glazed.

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.

CROWNS AND BRIDGES
Model and die preparation
Fabricate a working model with removable die segments. The application of a sealer is recommended to harden the surface
and to protect the stone die. However, the sealer layer must not result in any changes of the dimensions of the stone die.
Subsequently, the spacer is applied as described below. Please make sure to consider the expansion of the investment
material when applying the spacer.
– For single crowns, the spacer is applied in two layers up to max. 1 mm from the preparation margin (spacer application
9–11 µm per layer)
– Two sealer layers are also applied for bridge reconstructions.
– An additional layer is applied to the intercoronal surfaces of the abutments (facing the pontic). This layer
prevents undesired friction.

Sealer application in 2 layers…..
For bridges, 2 layers….
…up to max. 1 mm from the preparation margin
... and a third layer to the intercoronal surfaces are to be applied
18
Contouring
Contouring may vary depending on the available space. However, it must provide shape and cusp support in order to
achieve an even layer thickness of the veneering ceramic.
Always provide a shape- and cusp-supporting design and observe the minimum thicknesses.
For bridge reconstructions, fabricating a full wax-up of the restoration is recommended. To ensure the correct dimensions
of the connectors between bridge pontic and bridge abutment, IPS Connectors may be used.
Variant A: Ideal space
Variant B: Limited space
If enough space is available, the wax-up is reduced in the
buccal/labial, as well as in the palatal/lingual areas. In other
words, the share of the restoration that will be built-up
using layering material after pressing has to be reduced in
accordance with the images below. The relation between
the framework thickness (min. 0.8 mm) and the layering
material must be observed (i.e. at least 50% of the total
thickness is the framework).
If space is limited, the wax-up is only reduced in the buccal
and incisal areas. The palatal/lingual area may be pressed
with a fully anatomical design. In other words, the share of
the restoration that will be built-up using layering material
after pressing has to be reduced in accordance with the

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

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 difference between the two values is the weight of the wax used.

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. Pour the investment material slowly and carefully.
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.

If several Speed investments are
required, they should be invested with
a time difference and placed in the
preheating furnace at intervals of
approximately 20 minutes. When
placing the investment rings in the
preheating furnace, make sure that the
furnace temperature does not drop too
much. The indicated holding time starts
when the preheating temperature is
reached.
Do not preheat IPS e.max Press ingots and Alox plunger.
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.
24
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.
Contraindication:
Do not pull at the melting sample. The ceramic base may fracture when you do so.
9. Replace the firing tray and select the firing program. The furnace head closes automatically.
10. Once it is cooled, disassemble the calibration sample.
11. Use a new melting sample for the next calibration procedure and start with item 1.
25
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 Press 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 Press.
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 Press 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.

After the press program has ended, remove the hot investment ring from the furnace with
the investment tongs and place the ring on a wide-meshed cooling grid, where it is left to
cool to room temperature.
Remove the investment ring from the furnace immediately after the program is completed and close the
furnace. Place the investment ring on the cooling grid and allow it to cool to room temperature. The grid
ensures quick and even cooling of the investment ring and prevents undesired heat accumulation.
27
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).

28
Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure.
Divested IPS e.max Press objects with light reaction layer.
29
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
10 minutes and a maximum of 30 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 formed on the pressed objects using the Invex Liquid in an ultrasonic bath.
Completely remove the reaction layer from the contact surfaces using 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.
30
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 Press frameworks:
– Even though adjustment by grinding of pressed IPS e.max Press frameworks is possible, it should be kept to a minimum.
– Wet the area to be ground and use a fine diamond disk to cut the sprues.
– 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.
– Remove the spacer prior to placing the pressed object on the die. Place the framework on the die and carefully adjust.
– 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.
– Make sure that the minimum thicknesses are maintained even after finishing.
– 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.
After adjustment, an excellent accuracy of fit can be achieved.
Finish surfaces and smooth out the attachment points of the sprues using low speed and limited pressure.
31
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.
Coat the inner surfaces of the ceramic restoration with IPS Natural Die Material Separator and allow it to react for a short time.
Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the holder. Then, polymerize with a commercial polymerization light.
A die made of IPS Natural Die Material is the optimum basis for true-to-nature all-ceramic restorations.
32
Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or with steam before applying the veneering material.
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 tray and pins
Use a honey-combed firing tray and the corresponding support pins to fire the restorations (do not use
ceramic pins). Round the top edges of the support pin to prevent the object from sticking to the pin.
Another method of reducing this risk is to cover the pins with platinum foil or a small amount of
IPS Object Fix. Regularly clean the support pins. Do not use contaminated pins.
33
Wash firing (foundation firing)
The framework must be free of dirt and grease before the wash firing is done. Any contamination of the framework after
cleaning must be prevented. Wash firing (foundation) is carried out with Deep Dentin, Dentin or Shade and Essence
materials (ZirLiner may not be used. Because of its firing temperature of 960 °C/1760°F it only works on zirconium oxide).
Variant A: Powder
Variant B: Paste
With ideal space, conduct the wash firing (foundation)
with the required Dentin or Deep Dentin material. Use the
IPS e.max Ceram Build-Up Liquids (allround or soft) to mix
the materials. If a more plastic consistency is desired,
IPS e.max Ceram Glaze and Stain Liquids (allround and
longlife) can be used. Apply the wash in a thin coat on the
entire framework.
With limited space or to increase the in-depth chroma, the
wash firing can be conducted using IPS e.max Ceram
Shades and Essence. Mix the paste or powder with the
IPS e.max Ceram Glaze and Stain Liquids (allround and
longlife) to the desired consistency. Apply the wash in a
thin coat on the entire framework.

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.
The following steps must be observed:
– High-strength glass-ceramics are generally etched with hydrofluoric acid gel (IPS Ceramic Etching Gel) and, for adhesive
cementation, silanated (Monobond S).
– Glass-ceramics must not be blasted with Al2O3 or glass polishing beads.

– The parameters listed represent standard values and apply to the Ivoclar Vivadent furnaces: P200, P300, P500, PX1 and
EP 600 Combi. The temperatures indicated also apply to furnaces of older generations, such as the P20, P90, P95, P80,
and P100. If one of these furnaces is used, however, the temperatures may deviate by ± 10 °C/50 °F, depending on the
age and type of the heating muffle.
– If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary.
– Regional differences in the power supply or the operation of several electronic devices by means of the same circuit
may render adjustments of the firing and press temperatures necessary.
