Model the restoration in wax and invest.
After preheating the investment ring, the
ceramic material is pressed into the investment ring in the EP500 / EP600 press furnace. After divesting the pressed objects,
complete the restorations according to the
aesthetic and anatomic requirements using
the IPS Eris for E2 layering technique.

– Bruxism
Material
Framework material – IPS Empress 2
lithium disilicate glass-ceramic
The tried-and-tested material is a lithium
disilicate glass-ceramic, which permits the
fabrication of bridge restoration for the
anterior and premolar regions due to its
enhanced stability. This lithium disilicate
glass-ceramic demonstrates very dense crosslinking of the lithium disilicate crystals. With
a more than 60 % vol. crystalline phase, the
material demonstrates a higher crystal
content than leucite glass-ceramics. The
flexural strength, chemical resistance, and
fracture resistance are clearly higher than
those of leucite glass-ceramic.
Important processing
restrictions
The following restrictions must be observed,
to ensure success of the IPS Empress 2 /
IPS Eris for E2 layering technique.
– Obsere the required framework dimensions
(see page 23)
– Do not mix IPS Empress and IPS Empress 2
layering materials
– Do not mix metal-ceramic systems (e.g.
IPS d.SIGN)
– Do not mix powder material with materials
in paste form
– Do not apply IPS Empress Universal
Shade/Stains during layering (e.g. between
unfired dentin and incisal materials)
– Mixing of existing IPS Empress Shades/
Stains or IPS Empress 2 Stains with the
new Universal Shades/ Stains
– Mixing of existing IPS Empress Glaze and
IPS Empress 2 Glaze with the new
Universal Glaze
Layering material –
IPS Eris for E2 apatite glass-ceramic
It was our objective to develop a glassceramic material with optimized handling
properties, processing tolerance, and optical
characteristics by using apatite crystals,
which satisfies the requirements of users.
Apatite is a component of natural teeth,
influences the translucency, brightness and
light scattering ability. The IPS Eris for E2
Dentin, Incisal, Impulse, and Transparent
materials enable the fabrication of
restorations that blend in with the natural
environment.
Side effects
If patients are known to be allergic to any
of the components in the materials,
IPS Empress 2 / IPS Eris for E2 should
not be used.

Shade determination, die shade
selection, and ingot selection
The Chromascop shade
guide represents the shade
standard for Ivoclar Vivadent
products. With the logical
arrangement of the individual
shades, the Chromascop
permits exact and efficient
shade determination.
The 20 shades are divided
into five detachable shade
groups. Additionally, the
the incisal and dentin
areas, as well as surface
characterizations) greatly
helps determine the correct
shade. The following Ivoclar
Vivadent products are
coordinated with the
Chromascop shade guide:
Chromascop shade group for
bleached teeth provides four
ultra-light shades. Once the
basic shade has been
selected, the correct shade
within the shade group can
be determined.
Consequently ignoring any
superfluous effects (e.g.

Die shade selection
In order to facilitate the reproduction of the
tooth shade, dentists have the possibility of
communicating the shade of the preparation
to the dental laboratory using the
IPS Empress die material shade guide.
The corresponding shades of the ingots
are listed in the combination table.
IPS Eris for E2 layering technique shade guide
For reasons of light refraction, the new shade tabs have been given an
anatomical shape and a certain surface structure. On the reverse side, the
teeth are smooth, i.e. without any texture whatsoever, which facilitates
shade comparison with the prepared die and shaded cementation media.
The smooth side of shade tabs may be individually ground to determine the
layering. The shade tabs are fired from original materials under laboratorytype conditions. In this way, they correspond with the desired result.

Fabricating the model
Applying the spacer
It is advisable to apply a sealer to harden the surface and to
protect the die.
The application of a sealer must not cause any changes in
the dimensions of the die.
Fabricate a type IV die stone model with detachable
segments according to the impression.
Die stone type IV
The spacer is applied to maximum 1 mm from the preparation margin.
a) For single crowns, apply two layer of spacer up to
maximum 1 mm from the preparation margin (layer
thickness of spacer: 9–11 µm).
Crown
Schematic of the space layer.
b)Bridge restorations also require two layers of spacer. Apply
an additional layer of spacer to the intercoronal surfaces of
the abutments (the area facing the pontic). This measure
helps prevent undesired friction.

1. Select the IPS Connector recommended for the region for
which the fabricated bridge is intended and remove it
from the harness.
2. Once the bridge abutment has been modelled with wax,
attach the selected IPS Connectors to the connector area
between the pontic and the bridge abutment.
3. After that, complete modelling the full wax-up and secure
it with a silicone key.
4. The modelled bridge is now reduced in a targeted fashion.
In other words, the area that will be built-up using
layering material after the press cycle has to be carefully
reduced so that the framework thickness measures at least
0.8 mm (see page 23).
5. The plastic Connector ensures that the minimum
connector thickness between the pontic and the bridge
abutment is automatically observed during the reduction
process.
Correct dimensions of bridge connectors
using IPS Connector
IPS Connectors are prefabricated anatomically-shaped plastic
aides in six different shapes manufactured according to the
idea of Klaus F. Ernst, M.D.T. Stuttgart (Germany). They are
used in the contouring of three-unit IPS Empress 2 bridges
and ensure the adequate size of the connector between the
pontic and the bridge abutment.
The IPS Connectors C1–C6 have been designed in such a
way that dental professionals automatically achieve the
correct connector dimensions.
Areas of application
IPS Connector
Recommended area of
application
The following basic rule applies:
The connector area between the bridge abutment
and the pontic should measure at least 16 mm2.
Ideally, a connector area of 4 x 4 mm is established,
depending on the given situation and available
space.

Please remember that the framework material
represents the most stable component of your
restoration and has to be given the corresponding
attention. Since the translucency of the framework material
is similar to that of natural teeth, the aesthetic appearance
will not be compromised. In large preparations, the excess in
available space must be compensated by the design of the
framework and not by the layering material.
In anterior bridges, it is not always possible to
establish a connector area of 4 x 4 mm with regard
to the linguovestibular region. In these cases, the
linguovestibular portion of the connector area may be
reduced to 3 mm, if, at the same time, the portion from the
incisal to the cervical is increased to 5–6 mm.
If only limited space is available, non-aesthetic areas (e.g.
palatal, lingual 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. The physical properties and the
abrasion values of the framework material permit users to
use this technique without reservation.
Ratio of framework thickness to layering material thickness
representing the aesthetic component of the restoration.
The incisal portion of natural teeth is 1.5 mm on average.
Likewise, highly aesthetic restorative results can be achieved
by applying the IPS Empress 2 framework material and
IPS Eris for E2 layering materials in a overall thickness of
1.5 mm. Keep the required ratio between the framework
and layer thickness in mind when fabricating the framework.
The following guidelines apply: The framework must be
thicker than the layer thickness of the layering material. The
minimum wall thickness of the framework is 0.8 mm. The
table below serves as a reference guide:
Reference guide for determining the adequate
proportion of the framework to the layering material
thickness
In order to achieve the best possible surface stability by
creating ample compressive strength, it is imperative both to
observe the working parameters and to design adequate
IPS Empress 2 frameworks. The table below clearly shows
that the fundamental objective is to make the framework
thicker than the overlaying layering material. The framework
must be as substantial as possible, with the layering material

Version a: Adequate space is available
If adequate space is available, the bucco-labial and the
palatal-lingual portion of the modelled framework is reduced
in a targeted fashion. Reduce the wax-up by the space
required for the layering material to be applied after
pressing. Observe the necessary ratio of the framework
thickness to the layering material thickness, as described on
page 23. IPS Connector ensures that the minimum connector
thickness between the pontic and the bridge abutment is
observed.

Version b: Only limited space is available
(reduced layering technique)
Sprueing of the object
a) Single crowns
For single crowns, depending on the size and volume of the
wax pattern, attach an axial sprue in the direction of flow of
the ceramic material (see page 27).
Use round wax profile Ø 2.5–3 mm / 8 gauge; length 3 to
max. 8 mm.
If only limited space is available, only the buccal and incisal
portion of the modelled framework is reduced in a targeted
fashion. The palatal-lingual portion should be pressed in its
full anatomic shape.
Reduce the wax-up by the space required for the layering
material to be applied after pressing. Observe the necessary
ratio of the framework thickness to the layering material
thickness, as described on page 23. IPS Connector ensures
that the minimum connector thickness between the pontic
and the bridge abutment is observed.
b) Bridges
For three unit bridges, attach a 2.5 to 3 mm round profile
axial wax sprue directly to the abutment teeth at an approx.
45 to 60° angle.
For extremely delicate wax patterns (e.g. lower incisors), an
additional axial sprue may be attached to the pontic to
enhance the stability of the investment material.
Only the buccal and incisal portion of the modelled framework is reduced
The attachment points of the sprue to the object and sprue former must be rounded and smooth. Avoid
sharp edges.
The dimensions of the sprues are:
Round profile, length 3 to 8 mm, Ø 2.5–3 mm /
8 gauge. When selecting the diameter of the sprue,
take the dimensions of the object into account. Select a
thinner sprue for delicate objects.
c) Wax-pattern sprue attachment
– Pattern angled at 45–60 degrees
– The distance between paper ring and object must be at
least 10 mm
– All sprue attachments are flared and smooth
The palatal-lingual portion should be pressed in its full anatomic shape.
Provide sprues in the direction of flow of the ceramic material. Pattern angled at 45–60 degrees
The areas to be built up with layering material are clearly visible.
26
Correct sprueing:
Direct the sprues towards the wax pattern (imagine continuation of wax pattern).
The sprue and object together should not be longer than 15 mm. Observe an angle of 45–60°.
Place the sprues in the direction of flow of the ceramic material.
27
If the crown is viewed from the proximal, the longer side of the object (usually the buccal surface) points outwards. Additionally, the flow of the ceramic material must be observed.
The attachment points of the sprues must be rounded. Observe an angle of 45 to 60 °.
Observe a distance of at least 3 mm between the
individual objects.
Ring gauge
Observe a distance of at least 10 mm between the paper
ring and the objects to be pressed.
at least 10 mm
Remove excess separating material.
Consider the direction of low of the ceramic material when
positioning the sprues. For small objects invest a phantom
sprue together.
at least 10 mm
The distance between the objects to be pressed and the paper ring/ring gauge must be at
least 10 mm. This applies to all the above schematics.
28
Investing
Investing is carried out with the IPS Empress 2 Special
Investment material or IPS Empress 2 Speed Investment
material. We recommend the following procedure to
determine the accurate wax weight:
1. Weigh the ring base (seal the opening of the ring base with
wax).
2. Position the objects to be pressed on the ring base and
attach them with wax. Weigh again.
3. The difference between the two values is the weight of the
wax used.
– Large investment ring:
Up to max. 1.3 g wax weight requires one large ingot
– Small investment ring:
Up to max. 0.5 g wax weight requires one small ingot

Remove the investment ring from the burnout/preheating furnace immediately after completion of the
preheating cycle. Place the corresponding cold ingots for the layering technique (large or small) in the
investment ring (small ingot for single crowns; large ingot for several crowns or bridges).
... and than select large or small ring.
Next, position the AlOx plunger.
32
Divesting
(After approx. 60 minutes)
After cooling, 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 result of the pressing
cycle.
Select the program for the IPS Empress 2 layering technique. Set the exact press parameters. Place the
investment ring with ingot and the AlOx plunger at the center of the EP500/EP600 press furnace. Close the
furnace head. Activate the selected program by pressing START.
Check the vacuum
Mark the length of the AlOx plunger on the cooled investment ring.
The press cycle runs automatically. An acoustic signal indicates the end of the press cycle.
Separate the investment ring using a separating disk. This predetermined breaking point enables reliable
separation of the AlOx plunger and the ceramic material.
Remove the investment ring from the furnace
immediately after the program is completed and
close the furnace. Place the investment ring on a
wide-meshed grid (IPS Empress cooling rack) and allow to
cool to room temperature. The grid ensures quick and even
cooling of the investment ring and prevents undesired heat
accumulation.
Break the investment ring at the predetermined breaking point using a plaster knife.
33
Rough divestment is carried out with polishing jet medium (Ivoclar Vivadent) at 4 bar (60 psi) pressure.
Press result after pressing at too low a temperature.
For fine divestment, only 2 bar (30 psi) pressure is applied.
If the temperature of the furnace has been set correctly, the pressed objects exhibit only a
thin reaction layer that can be easily removed, following the directions given below.
If the object is pressed at too high a temperature, a substantial reaction layer forms that is
difficult to remove. If the reaction layer is not completely removed, the bond to the layering
material is impaired.
When divesting the object, blast from the direction indicated in the schematic at the top.
34
Removing the pressed object / finishing
Excessive grinding results in local overheating of
the ceramic framework and may lead to microcrack
formation.
Therefore, keep grinding to a minimum.
Do not press the anatomical wax-up and subsequently reduce by grinding.
Subsequently, identify the reaction layer from the pressed object using the Invex liquid in the ultrasonic unit
for 10–30 minutes (place the object in a plastic cup). Next, thoroughly rinse the object with running
water and blow it dry. Carefully remove the (white) reaction layer with Special Jet Medium
(Al2O3 = Type 100 microns) at 1 bar (15 psi) pressure.
Always use glass beads (Ivoclar Vivadent) to divest
ceramic restorations (rough and fine divestment).
Removal of the reaction layer: Identify the reaction layer
with Invex liquid from the pressed IPS Empress 2 frameworks. Immerse the object in Invex liquid for max. 30 min.
Thoroughly rinse the object with water and blast
it with Al2O3 (Type 100 microns) at 1 bar (15 psi) pressure.
Use a fine diamond disk to cut the sprues. Guide the diamond disk through a wet sponge during cutting to
ensure permanent wetting of the area to be ground. In this way, overheating of the ceramic framework is
avoided. Use ceramic burs to process the attachment points of the sprues.
Make sure to remove the reaction layer completely from all
inner surfaces and all external surfaces (repeat this
procedure as necessary).
If the reaction layer is not completely removed, bubbles
may form, which subsequently may lead to bonding
problems and cracks in the layering ceramic.
Make sure that a material thickness of at least
0.8 mm is maintained throughout the object.
Never prepare any area that is less than 0.8 mm
thick.
Replace the Invex liquid after 20 applications or after
sedimentation of the liquid.
Avoid excessive heat development during grinding to
prevent microcracks from occurring. Therefore, provide
ample water cooling during removal of the sprues (use a
sponge, as depicted above).
Warnings:
– The Invex liquid contains < 1 % hydrofluoric acid.
– Invex liquid is harmful when inhaled, swallowed, and
when in contact with the skin. Furthermore, it is
corrosive.
– Keep the container tightly sealed and store it in a wellventilated 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 clear 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).
It is strongly advised that rotary instruments not be used to
clean the framework. Only blast with Al2O3 (Type 100
microns), using light pressure (1 bar/15 psi). If, however,
grinding must be done, i.e. contact areas, margins, etc., only
fine diamonds at low speed with light pressure and watercooling should be used.
Do not 'post-separate' the framework with separating disks.
This may result in undesired predetermined breaking points,
which will subsequently compromise the stability of the allceramic restoration.
Avoid the inhalation of grinding dust.
Disposal:
Carefully neutralize the diluted solution by adding
lime or baking soda (sodium carbonate, Na2CO3)
and letting it react for 5 minutes. After the reaction time,
pour the neutralized solution into the sink, flushing it with
running water.
35
Fit the framework to the die
Remove the spacer prior to fitting the pressed object to the
die. Be careful when fitting the object. In case of interfering
irregularities, cover the die with a thin layer of a suitable
control paste. Then, fit the object on the die again. Carefully
remove interfering irregularities with a fine diamond. Use
finishing diamonds or fine emery disk, to adjust the margins,
if necessary.
Always work with water cooling to avoid
overheating of isolated areas.
Apply the corresponding Die Material to the inner surface of the restoration, using the IPS Empress Die
Material Condenser.
IPS Empress Die Material
Control die
Fabricate a die according to the shade information supplied
by the dentist (shade selection), using the IPS Empress Die
Material Kit. This die enhances the shading of the
restorations.
Insert a die holder into the material. Here, a premolar is shown.
The Die Material is cured with a light-polymerization device
(e.g. Targis Power).
The IPS Empress Die Material is used to enhance the shading of the restoration.
Coat the inner surfaces of the ceramic object with IPS Empress Die Material Isolating Liquid.
36
IPS Eris for E2 foundation firing
Carefully blast the ceramic framework with Al2O3, Type
100 microns (Special Jet Medium, Ivoclar Vivadent) at 1 bar
(15 psi) pressure prior to the foundation firing. Clean with
steam and dry with oil-free air. Avoid any contamination from
this time onwards. Depending on the clinical situation and
available space, the foundation firing can be conducted in two
different ways.
Some blasting machines may require different
pressure settings to accomplish this procedure.
Applying the foundation.
Version a: Powder
If sufficient space is available, conduct the foundation firing
using the desired dentin shade (IPS Eris for E2 powder).
IPS Eris for E2 Build-Up Liquid of IPS Empress Universal Glaze
and Stain Liquid must be used for mixing. Apply a thin
uniform layer on the entire framework.
Premolar framework after firing.
Version b. Paste
If space is limited or to increase the chroma from the depth,
IPS Empress Universal Shades can be used for the foundation
firing. Thin the desired IPS Empress Universal Shade (paste)
with the IPS Empress Universal Glaze and Stain Liquid to the
desired consistency. After that, apply a thin uniform layer on
the entire framework (even with the reduced layering
technique).
No material must be layered on unfired
IPS Empress Universal Shade (paste), since this
would result in the IPS Eris for E2 layering ceramic
to delaminate.
The same procedure is used …
Select an individual firing program and set the correct firing
parameters and/or check them. Only use the IPS Empress
honey-combed tray and firing pins provided with the system.
Do not use silicon nitride support pins.
... for bridges.
37
IPS Eris for E2 dentin/incisal firing, and
Impulse material firing
Make sure that the firing trays are clean to
prevent the framework from sticking to the tray.
Use a firing pillow, if necessary.
Model the dentin and incisal materials, as well as the Impulse
materials in the usual manner, using the IPS Eris for E2 buildup liquid.
The IPS Eris for E2 build-up liquid can be diluted
with distilled water, if necessary.
IPS Eris for E2 layering diagram
Round the top edges of the support pin (left) to prevent the object from sticking to the pin. Pins whose top
edges have not been rounded (right) increase the risk of objects sticking to them. Another possibility to
reduce this risk is to cover the pins with platinum foil. This method produces the same effect as the
rounding of edges.
Additionally, prevent crown margins from sticking to the pin.
Do not use support pins made of ceramic.

Important
When working with a furnace from another
manufacturer, these parameters have to be
adjusted accordingly.
Any additional firing cycles can be carried out
using the same firing program.
When finishing bridges, only the interproximal area of the
layering material should be separated.
Do not use separating disks to work on the high-strength
frameworks.
The same procedure is used for single restorations. Here, a premolar is shown.

Examples of correct and incorrect firings
Glaze and stain firing with IPS Empress
Universal Shades/Stains, and Glaze
The IPS Empress Universal Shades/Stains, and Glaze have
been especially developed for the ceramic materials of the
IPS Empress System from Ivoclar Vivadent. They can be used
for the following techniques:
– IPS Empress staining technique
– IPS Empress layering technique
– IPS Empress 2 / IPS Eris for E2 layering technique
Do not mix the IPS Empress Universal Shades and
Stains in paste form with the powder materials.
Moreover, they must not be applied during
layering, i.e. between unfired dentin and incisal materials.
The temperature for firing this crown has been set too low. The crown shows clear signs of insufficient
firing.
Before starting the staining procedure, make sure
the restoration is free of dirt and grease. A
roughened surface is favourable.
If the restoration exhibits a shining, true-to-nature appearance, it has been fired with all the firing
parameters set correctly.
Stain and characterization firing
Extrude the desired IPS Empress Universal Shade/Stains from
the syringe and dilute it to the desired consistency using the
Universal Glaze and Stain Liquid and mix. There are
14 IPS Empress Universal Stains available for individualized
characterizations.
The firing temperature for this restoration was set too high.
Applying the stains in a thin layer.

Etching
Cementation
Etching the internal surfaces is necessary for all IPS Empress
restorations. This procedure increases the shear bond
strength between the IPS Empress material and the
composite cement.The fracture resistance of the restoration
is also increased.
Restorations fabricated with the IPS Empress 2 / IPS Eris
for E2 layering technique may be cemented with either
the adhesive cementation technique (Variolink II) or
conventional glass-ionomer cements.
– Cements with higher expansion rates must not be used (e.g.
hybrid ionomer cements).
– Restorations fabricated in the IPS Empress staining
technique or the IPS Empress layering technique must be
cemented using the adhesive technique.
Etch the internal surfaces of the IPS Empress 2
framework ceramics for 20 seconds using
IPS Ceramic Etching Gel.
Observe the note accompanying the IPS Ceramic Etching
Gel.

The IPS Empress 2 / IPS Eris for E2 layering
technique requires a glaze firing.
Basically, the following rule applies: the longer the holding
time, the more pronounced is the lustre. If the glaze of the
ceramic surface is insufficient, a second glaze firing may be
conducted.
Select the program for the IPS Empress 2 layering technique by pressing F3
These firing parameters represent standard values
applicable to the P80, P100, and PX1 furnaces from
Ivoclar Vivadent. The temperatures indicated also
apply to furnaces of older generations, such as the P20, P90,
and P95. If one of these furnaces is used, however, the temperatures may deviate by ± 10 °C/18 °F, depending on the
age and type of the heating muffle.
If a non-Ivoclar Vivadent furnace is used, temperature corrections may be necessary.
... and than select large or small ring.
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.
These press parameters are mandatory for the
EP500/EP600 press furnaces.
