Empress
Nearly 20 years ago, IPS Empress revolutionized the processing of ceramic and thanks to the many advantages of the
leucite- reinforced glass-ceramic, such as esthetics, IPS Empress has been established as the "benchmark". More than
33 million restorations fabricated of IPS Empress throughout the world and the use of "IPS Empress" as a synonym for
all-ceramics speak for the durable life-like appearance, the ongoing success, and the high quality standard of the material.
In addition to the tried-and-tested PRESS technology, the CAD/CAM technology has also developed in the area of allceramics. In order to supply the "benchmark" for this technology as well, the IPS Empress System comprises products for
both processing technologies. You will be able to benefit from roughly 20 years of clinical experience and convincing
esthetics, irrespective of whether the restorations were fabricated with the PRESS or CAD/CAM technique.
IPS Empress Esthetic is available for the PRESS technology, while IPS Empress CAD is used in the CAD/CAM
techno logy. Both products consist of the highly esthetic, leucite-reinforced glass-ceramic that has been clinically tried-
and-tested for many years. The two ceramics are characterized by excellent strength values and outstanding esthetic
appearance. They may thus be used for the fabrication of full-contour single-tooth restorations, such as inlays, onlays,
veneers, and crowns.
Both products may subsequently be stained and/or glazed using IPS Empress Universal Shade / Stains / Glaze, or
individually veneered using the IPS Empress Esthetic Veneer layering ceramic.
– the Original
In this way, the IPS Empress System will remain synonymous for highly esthetic, full-contour all-ceramic restorations,
irrespective of the processing technology.

Product Information
Material
IPS Empress CAD is used for the fabrication of highly esthetic,
full-contour single-tooth restorations by means of the CAD/CAM
technology.
IPS Empress CAD blocks are made of a leucite-reinforced glassceramic which consists of a glass and a crystal phase. Leucite crystals
of few microns evenly grow in a multi-stage process directly from the
amorphous glass phase. During the fabrication of the blocks, the
semi-finished product in powder form is pressed to blocks in a fully
automated procedure, which enables a maximum of homogeneity.
Given the difference in the coefficients of thermal expansion (CTE)
between the glass phase and the crystal phase (leucite), cooling after
sintering produces compressive stress in the glass phase. This
mechanism results in an increase in strength and enables IPS Empress
CAD to achieve a flexural strength of 160 MPa. This type of material
has been successful as well as proven for almost 20 years. The milled
restorations feature excellent accuracy of fit and a homogeneous
surface structure. Subsequently, the restorations may be stained
using IPS Empress Universal and/or individually veneered using IPS
Empress Esthetic Veneer.

Block concept
IPS Empress CAD Blocks
The shading and translucency control of the IPS Empress CAD Blocks is based on the well-known translucency concept. The
system is built on the A-D, Chromascop, and Bleach BL shade guides.
The IPS Empress CAD Blocks are available in two degrees of translucency and as a polychromatic block. The blocks are
precisely coordinated with the respective indications and thus enable excellent shade match with the corresponding shade
guide. Depending on the indication, the blocks provide a true-to-nature chameleon effect, life-like brightness value, or a
natural shade transition.
IPS Empress CAD HT (High Translucency)
These blocks are available in the 9 most popular A–D shades, 3 Chromascop shades, and 4 sizes. Given their high
translucency, HT blocks are ideally suitable for the fabrication of smaller restorations (e.g. inlays and onlays). Restorations
made of HT blocks impress users with their true-to-nature chameleon effect and outstanding adaptation to the residual
tooth structure. The blocks demonstrate life-like fluorescence in order to permit optimum integration into the natural
residual tooth structure under different light conditions.
A–D
Chromascop
IPS Empress CAD LT (Low Translucency)
These blocks are available in the 9 most popular A–D shades, 3 Chromascop shades, 4 Bleach BL shades, and 4 sizes. Given
their high brightness value compared to the HT blocks, the LT blocks are ideal for the fabrication of larger restorations (e.g.
anterior and posterior crowns). Restorations made of LT blocks impress users with their true-to-nature brightness value and
chroma, which prevents a greying of the incorporated restorations. The blocks demonstrate a life-like fluorescence in order
to enable optimum integration into the natural environment, even under varying light conditions. Restorations made of LT
blocks are also ideally suitable for the cut-back technique.
A–D
Chromascop Bleach BL
IPS Empress CAD Multi
These blocks are available in the 5 most popular A–D shades and 3 sizes. Given the
natural shade gradient from the dentin to the incisal areas, restorations made of
IPS Empress CAD Multi Blocks demonstrate a maximum of esthetics and naturalness.
The true-to-nature opacity and translucency gradient enables a multitude of esthetic
possibilities. The IPS Empress CAD Multi Block features a transition of fluorescence very
similar to that of natural teeth, which results in excellent integration into the residual
dentition. Given the innovative combination of true-to-nature transition of shade,
translucency, and fluorescence, highly esthetic restorations are fabricated in an easy way.
The available product range may vary from country to country and is also dependent on the CAD/CAM
system used.

Successful results can only be achieved with IPS Empress CAD if the preparation guidelines and layer thicknesses are strictly
observed. The following minimum thicknesses are required for IPS Empress CAD restorations.
Inlays and onlays
It is absolutely necessary that you take the static and dynamic antagonist contacts into consideration. Do not locate the
preparation margins on centric antagonist contacts.
Observe a preparation depth of at least 1.5 mm and an isthmus width of at least 1.5 mm in the fissure area. Prepare the
proximal box with slightly diverging walls and observe an angle of 100–120° between the proximal cavity walls and the
prospective proximal inlay surfaces. For inlays with pronounced convex cavity walls without adequate support by the
proximal shoulder, avoid marginal ridge contacts. Round out internal edges in order to prevent stress concentration within
the ceramic material. Eliminate the proximal contacts on all sides. Do not prepare slice-cuts or feather edges.

Observe at least 2 mm of space in the cusp areas. Ensure that the shoulder does not show any inclinations, i.e. it must
show a 90° angle to the residual tooth structure. Onlays are indicated if the preparation margin is less than approximately
0.5 mm away from the cusp tip, or if the enamel is severely undermined.

Veneers
If possible, the preparation should be entirely located in the enamel. Do not locate the incisal preparation margins in the
area of the abrasion surfaces or dynamic occlusal surfaces. You can achieve a controlled enamel reduction by preparing
orientation grooves using a depth marker. You are not required to eliminate the proximal contacts.
For preparations without embrasure of the incisal edge (only labial reduction), observe a preparation depth of at least
0.6 mm in the cervical area and of at least 0.7 mm in the labial area.
For preparations with oro-incisal embrasure of the incisal edge (labial / incisal reduction), observe a preparation
depth of at least 0.6 mm in the cervical area and of at least 0.7 mm in the labial area. Reduce the incisal edge by 1.0 mm.
The extent of the incisal reduction depends on the desired translucency of the incisal area to be built up. The more
transparent the incisal edge of the intended veneer, the more pronounced the reduction should be. Discoloured teeth
may require more preparation.

with rounded inner edges or a chamfer. Observe a width of the circular shoulder/chamfer of at least 1 mm. Reduce the
crown third – incisal and/or occlusal – by 2 mm. For anterior crowns, reduce the labial and/or palatal / lingual part of the
tooth by at least 1.5 mm. Ensure that the incisal edge of the preparation is at least 1.0 mm (milling tool geometry) in order

Shade determination
The correct tooth shade is the basis for a restoration with a life-like appearance. After tooth cleaning, the tooth shade of
the non-prepared tooth and/or the adjacent teeth is determined. Individual characteristics have to be taken into consideration when determining the tooth shade. If a crown preparation is planned, for example, the cervical shade should also be
determined. In order to achieve true-to-nature results, shade determination should be carried out at daylight. Furthermore,
the patient should not wear clothes of intensive colours and/or lipstick. Basically, it has to be kept in mind that the final
shade of the restoration is the result of the following individual shades:
– the shade of the preparation;
– the shade of the ceramic block;
– the shade of the layering ceramic;
– the shade of the cementation material.
CAD – Overview of the Treatment Procedure
®
IPS Empress
IPS Natural Die Material
In order to facilitate the reproduction of the tooth shade, the shade of
the prepared tooth can be determined with the help of the IPS Natural
Die Material shade guide. This facilitates the fabrication of the allceramic restoration and the individual characteristics of the preparation may also be taken into consideration. By fabricating a working
die made of IPS Natural Die Materials in the respective shade of the
preparation, the shade and brightness value of the IPS Empress CAD
restorations may be checked during the individual fabrication steps.
13
Intra-oral imaging
To prepare for the optical imaging, OptraGate® is placed to facilitate access to the
treatment field. OptraGate is a clinical auxiliary device that retracts lips and cheeks
during dental treatment. It enables a full view of the treatment field, facilitates the
accessibility, and improves the moisture control in the oral cavity.
The IPS® Contrast Spray Chairside is used to achieve optimum recordings for
CAD/CAM restorations. The IPS Contrast Spray Chairside balances out the
different optical properties of the natural tooth (dentin and enamel) and
thus permits optimum impressions using a camera. With the atomizing
nozzle, an optimum covering layer with a detailed representation of the
edges is achieved easily and efficiently with only a short spray discharge.
Angled atomizing heads are available for the spray.
Milling
In order to mill the restoration, IPS Empress CAD Blocks are selected in accordance
with the corresponding clinical situation. The clinical situation not only determines
the selection of the block in the required shade and translucency, but also the size
of the block used. Once the desired block has been selected, it is mounted in the
CAM unit and the restoration is milled.
Several options are available to finish and complete the restorations. Please refer
to the Chapter "Fabrication of IPS Empress CAD Restorations" for detailed
descriptions of the individual working steps of the various processing methods.
14
Staining and veneering
There are three different techniques for staining, characterizing, and veneering
IPS Empress CAD.
Internal characterization
IPS Empress
®
Direct Color are light-curing composite stains for individual characteri-
zation. They are ideally suitable for internal characterizations (cementation side) of
IPS Empress CAD restorations (e.g. veneers). After etching (60 seconds with
IPS Ceramic Etching Gel) and silanating (Monobond Plus), the stains are applied.
Subsequently, the stains are polymerized with a curing light of the Bluephase family.
No further ceramic firing cycles must be conducted after the "internal
characterization" with IPS Empress Direct.
External characterization*
IPS Empress
®
Universal Shade / Stains are ceramic stains for individualized
characterizations. Among other things, they are ideal for external staining and
characterization of IPS Empress CAD restorations.
The dentin stains are available in 9 A-D and 15 Chromascop shades.
For individualized characterizations, 14 intensive stains are available. To reproduce
the incisal area, there are 2 Incisal Shades, which provide the incisal third with optical
translucency and an in-depth effect. For the final glaze firing of the IPS Empress CAD
restorations, a smooth and fine-grained glazing paste is available.
Cut-back technique*
IPS Empress
®
Esthetic Veneer ceramic materials are leucite-reinforced layering
materials for the cut-back technique. In this technique, full-contour IPS Empress CAD
restorations (veneers and anterior crowns) are reduced in the incisal third to a
dentin-mamelon structure and subsequently completed using materials in paste and
powder form in order to design a true-to-nature and esthetic incisal third.
CAD – Overview of the treatment process
®
IPS Empress
The IPS Empress Veneer Kit comprises a selection of the most popular wash pastes and
layering materials required for the cut-back technique of IPS Empress restorations
(Esthetic and CAD). With the wash pastes, an excellent and homogeneous bond with
the reduced restoration is achieved. The layering materials feature incisal-like fluorescence and true-to-nature opalescence. Additional wash pastes and layering materials
available as Refills are indicated on the material shade guide supplied with the Kit.
* Please refer to the Combination Tables for the available shades and materials.
15
Ceramic firing
IPS Empress CAD restorations are generally fired on a honey-comb firing tray. For that
purpose, the restorations are placed either on a firing pillow or metal pins. As an alternative and to better secure the restorations on the metal pins, IPS® Object Fix Putty /
Flow auxiliary firing paste can be used.
Ceramic firing is conducted in the Programat® CS2 ceramic furnace. The furnace
impresses with its economic efficiency and easy operating concept. The furnace is
supplied from the factory with preset programs for IPS Empress and IPS e.max.
Etching and silanating
Conditioning of the ceramic surface in preparation for the adhesive cementation is
critical for generating a sound bond between the cementation material and the allceramic restoration.
Generally, glass-ceramics are etched using IPS® Ceramic Etching Gel.
Etching produces retentive bonding surfaces, which increases the
bond between the luting composite and the all-ceramic restoration.
IPS Ceramic Etching Gel is exclusively intended for extra-oral use
and must not be applied in the oral cavity.
Subsequent silanating of the bonding surface using Monobond® Plus results in a
sound bond between the etched all-ceramic material and the luting composite. The
bonding silane is thus an important contributor to the bonding strength between the
IPS Empress CAD restoration and the tooth structure.
16
Cementation
To prepare for the adhesive cementation, a dry operating field, must be established,
preferably using a rubber dam.
The OptraDam® is a convenient, 3-dimensional rubber dam, which can be quickly and
easily inserted thanks to its anatomical shape and the integrated frame. Given its high
flexibility and new functional concept, the OptraDam is very comfortable for patients
even for longer treatment procedures. The gentle, circular retraction of lips and cheeks
enables substantially facilitated access to an enlarged treatment field with simultaneous
isolation.
Total Etch
Total Etch is used for the preparation of adhesive cementation with Variolink. It is an
enamel etching and dentin conditioning gel used during the adhesive cementation of
all-ceramic restorations.
For the adhesive cementation of IPS Empress CAD restorations, you may choose
between tried-and-tested luting composites from Ivoclar Vivadent. Adhesive cementation achieves an excellent bond between the preparation and the restoration.

Veneer
Variolink Veneer is a purely light-curing luting composite in seven "Value"
shades for the adhesive cementation of translucent all-ceramic restorations
with a layer thickness of < 2.0 mm (veneers, inlays, onlays).
17
Multilink® Automix
The universal, self-curing (with light-curing option) luting composite Multilink
Automix offers a broad range of indications and produces very high adhesive
strength on all material surfaces. Together with the self-etching Primer, which is
applied as a simple preliminary layer on enamel and dentin, Multilink Automix is
processed quickly and efficiently.
Bluephase
LED lights of the Bluephase® family are used for the polymerization of light-curing
and dual-curing adhesive composites.
The high light intensity achieved with the Bluephase curing light permits comparatively
short polymerization times with simultaneous good polymerization depth.
®
Polishing
OptraFine, the specially developed, high performance chairside diamond polishing
system for ceramic materials combines the highest efficiency with outstanding polishing results. With regard to both low surface roughness and outstanding esthetic gloss,
OptraFine leaves nothing left to be desired. In contrast to other ceramic polishers,
OptraFine is autoclavable and therefore reusable.
OptraFine is available in the shapes "flame", "cup", and "disc".
Polishing is carried out in three steps:
– Finishing/smoothing out of the surfaces using the Finisher F
– Polishing using the Polisher P
– Polishing to a high gloss using the high-gloss brush and diamond
polishing paste HP

IPS
Inlays / Onlays – polished
IPS Empress CAD restorations are ideally suited to restore small defects with an all-ceramic material, as well as to replace
less esthetic restorations. Given the true-to-nature chameleon effect, IPS Empress CAD restorations beautifully blend in
with the residual tooth structure. In this processing technique, the restoration is polished and incorporated immediately
after milling in the CAD/CAM system. In the process, the surface lustre is achieved by manual polishing. Therefore, this
processing method is very efficient and leads to esthetic results in a quick and easy fashion.
For information on the CAD/CAM processing, please refer to the respective Instructions for Use and the
manuals of the respective CAD/CAM system. The instructions of the manufacturer must be observed.
The available product range may vary from country to country and may depend on the CAD/CAM system used.
Finishing
For finishing and adjusting glass-ceramics, appropriate grinding instruments are indispensable. If the wrong grinding instruments are used, marginal chipping and local overheating may occur.
CAD Restoration – Inlays / Onlays – polished
®
Fabrication of an IPS Empress
The following procedure is recommended for finishing IPS Empress CAD restorations:
– Use only suitable, fine-grained (grain size < 60 µm), ceramic-bonded grinding instruments or diamonds at a speed of up
to 20,000 rpm and little pressure.
– Carefully finish the restoration margins using rubber and silicone polishers (speed: < 10,000 rpm).
– Avoid overheating of the glass-ceramic.
– Smooth out the attachment point of the holder and take the proximal contact points into account.
– Carry out individual shape adjustments, if required.
– Try in the restoration and adjust the occlusion / articulation, if necessary.
– Polish proximal areas and large surfaces extra-orally prior to cementation.
The attachment point of the holder is smoothed out, while the proximal contact points are taken into account. Proximal areas and larger surfaces are polished extra-orally.
19
Adhesive cementation
Preparation of the IPS Empress CAD restoration
To condition it for placement, etch the IPS Empress CAD restoration for 60 seconds using IPS Ceramic Etching Gel and
clean it under running water. Subsequently, silanize the bonding surface of the restoration using Monobond Plus. Observe
the corresponding safety instructions.
The IPS Empress CAD restoration is etched using the IPS Ceramic Etching Gel. The IPS Empress CAD restoration is silanized using Monobond Plus.

You may choose between tried-and-tested luting composites from Ivoclar Vivadent for the adhesive cementation. In the
documented case, Variolink II / Syntac were used.
– To condition the preparation for adhesive cementation with Variolink II / Variolink Veneer, Total Etch is used. Total Etch is
an enamel etching (30 seconds of etching) and dentin conditioning material (10–15 seconds of etching).
– To condition the preparation for adhesive cementation with Multilink Automix, Multilink Primer A/B is used.
The restoration is positioned and excess material is removed. For polymerization, the restoration margin is covered with glycerine gel and the restoration is
polymerized from all sides.

Polishing
After the restoration has been adhesively cemented, the occlusion / articulation is adjusted with fine diamonds.
Subsequently, the restoration is manually polished in three easy steps. In order to achieve a life-like surface gloss, follow the
instructions below:
– For polishing, we recommend the high-performance, chairside diamond polishing system OptraFine.
– Always pay attention to the contact points and margins during polishing.
– Use the corresponding speed and little pressure to avoid heat development.
– Polish proximal areas and large surfaces extra-orally prior to cementation.
Step 1: Finish/smooth out the surfaces (e.g. proximal areas) using the Finisher F (speed: max. 15,000 rpm, water cooling).
This polisher smoothes out the milling grooves of the approx. 60 µm diamond of the CAD/CAM milling unit.
Step 2: Polish the restoration using the Polisher P (speed: max 15,000 rpm, water cooling).
Step 3: Polish the restoration to a high gloss using the high-gloss brush and diamond polishing paste HP (speed: max.
15,000 rpm).

Inlays / Onlays – stained / glazed
The 2-in-1 technique is suitable for efficient glazing and staining of inlays and onlays. In this technique, the glaze and stain
firing is conducted in one single step. Even though this technique does not permit as many shade adjustments as a
separate stain firing, the possible adjustments are entirely sufficient for the size of the restoration. If more intensive and
extensive shade adjustments are desired, we recommend conducting a separate stain and characterization firing (as
described in the following chapter).
For information on the CAD/CAM processing, please refer to the respective Instructions for Use and the
manuals of the respective CAD/CAM system. The instructions of the manufacturer must be observed.
Finishing and preparing for stain and glaze firing
For finishing and adjusting glass-ceramics, appropriate grinding instruments
are indispensable. If the wrong grinding instruments are used, marginal
chipping and local overheating may occur. The following procedure is
recommended for finishing IPS Empress CAD restorations:
– Use only suitable, fine-grained (grain size < 60 µm), ceramic-bonded
grinding instruments or diamonds at a speed of up to 20,000 rpm and
little pressure.
– Avoid overheating of the glass-ceramic.
– Smooth out the attachment point of the holder and take the proximal
contact points into account.
– Carry out individual shape adjustments, if required.
The attachment point of the holder is smoothed out, while the proximal
contact points are taken into account.
Before the stain and glaze firing, the restoration must be free of dirt and
grease. Avoid any contamination after cleaning. The following working
procedure should be observed:
– Before staining, blast the restoration with Al
(caution: abrasive) and clean it under running water or with a steam jet.
– Certain blasting devices require different settings for the intended blasting
procedure.
2-in-1 technique – Stain and glaze firing with IPS Empress Universal
Once the restoration has been cleaned, the stains and glazing material is applied in two steps. First, the glazing paste is
applied, followed by the Stains, which are applied on the unfired glaze layer.
The following working procedure should be observed:
Step 1 – Application of the glazing material:
– Extrude IPS Empress Universal Glaze Paste from the syringe and mix thoroughly.
– Thin the material to the desired consistency using IPS Empress Universal Glaze and Stain Liquid. Do not excessively dilute
the material, since this may render the glazing procedure difficult to control.
– Apply the glazing material on the entire outer surfaces of the restoration.
– The glazing material must not come into contact with the inner aspects of the restoration.
– Avoid pooling and excessively thick glazing material layers.
– Excessively thin glazing material layers result in an unsatisfactory gloss.

Step 2 – Application of Shade / Stains:
– Extrude IPS Empress Universal Shade or Stains from the syringe and mix thoroughly.
– Thin the material to the desired consistency using IPS Empress Universal Glaze and Stain Liquid.
– Apply the mixed Shade material directly into the unfired glazing material layer.
– Intensify the corresponding dentin shade in the cervical and occlusal areas using IPS Empress Universal Shade.
– To imitate the incisal area and translucency in the incisal third, use IPS Empress Universal Shade Incisal.
– Apply individualized effects and characterizations on cusps and in fissures using the Stains materials. Only apply the
Stains once staining with the Shade materials has been completed.
– Apply the Stains thinly and in a controlled manner on the unfired glazing material layer using a brush.

Mixed Shades are applied directly into the unfired glazing material layer. The corresponding
dentin shade is intensified in the cervical and occlusal areas and IPS Empress Universal Shade
Incisal is used to imitate the incisal areas.
Individualized effects and characterizations are applied on cusps and in fissures using the
Stains materials.
After glazing and staining, the glaze and stain firing is conducted in a compatible ceramic furnace (e.g. Programat CS2).
The following points should be observed when placing the restoration in the furnace and setting the firing parameters:
– Support inlays and onlays with a firing pillow and place them on the
honey-comb firing tray.
– As an alternative to the firing pillow, a small amount of IPS Object Fix
Putty / Flow may also be used.
– Restorations supported with a firing pillow on the honey-comb tray are
exposed to less heat due to their lower position in the firing chamber. In
order to achieve a true-to-nature gloss nonetheless, it is recommended
to extend the holding time from 1 minute to 2 minutes.
– Make sure that the firing pillow is regularly replaced in order to prevent
contamination.
The objects are placed on the honey-comb firing tray and the firing
program is started.

If more intensive and excessive shade adjustments are desired, we recommend conducting them in several working steps.
To reproduce the tooth shade easily and reliably, an individual control die may be fabricated using the IPS Natural Die
Material. The IPS Empress Universal Shade and Stains are then applied in a first step and separately fired. The shade result
can be checked after firing. If required, the shade of the restoration may be intensified and adjusted to the individual
patient case by repeated application of the materials. Once the desired shade has been achieved and the individualized
characterizations completed, the glaze firing is conducted.
For information on the CAD/CAM processing, please refer to the respective Instructions for Use and the

Finishing
For finishing and adjusting glass-ceramics, appropriate grinding instruments are indispensable. If the wrong grinding
instruments are used, marginal chipping and local overheating may occur.
The following procedure is recommended for finishing IPS Empress CAD restorations:
– Use only suitable, fine-grained (grain size < 60 µm), ceramic-bonded grinding instruments or diamonds at a speed of up
to 20,000 rpm and little pressure.
– Carefully finish the restoration margins using rubber and silicone polishers
(speed: < 10,000 rpm).
– Avoid overheating of the glass-ceramic.
– Smooth out the attachment point of the holder and take the proximal
contact points into account.
– Carry out individual shape adjustments, if required.
– Design the surface structure somewhat more pronounced, if necessary,
since it will be toned down by the glazing procedure.
Individual shape adjustments and a true-to-nature surface structure are
designed.

Veneers / Anterior Crowns –
cut-back and layered
In order to individualize restorations in the incisal area so that they correspond with their natural model, the
IPS Empress CAD restoration is additionally veneered using opalescent IPS Empress Esthetic Veneer ceramic
materials.
The cut-back technique is very efficient if the full-contour anterior crown or the veneer is first designed
according to the definite final shape. After that, the incisal third is reduced and subsequently provided with
an individualized esthetic veneer.
For a detailed description of the materials used and the individual working steps, please refer to the
Instructions for Use of IPS Empress CAD labside.
After the CAM process, the fitted IPS Empress CAD
restoration is partially reduced using suitable grinding
instruments. Excess pressure and overheating is
prevented. No extreme mamelon structures are milled.
The wash firing is performed using the IPS Empress
Esthetic Veneer Wash Pastes.
The anatomical shape of the reduced areas is
completed using IPS Empress Esthetic Veneer materials.

Firing parameters
Firing process for leucite-reinforced glass-ceramic restorations
– Always use the honey-comb firing tray to fire the restorations.
– Support inlays, onlays, and partial crowns with a firing pillow and place them on the honey-comb firing tray.
– Place veneers as well as anterior and posterior crowns on metal pins and position them on the honey-comb firing tray.
– As an alternative to the firing pillow and to better secure the restoration on the metal pins (particularly with veneers), a
small amount of IPS Object Fix Putty / Flow may also be used. The inner aspects do not have to be completely covered.
– Observe the firing temperatures at all times. An increase in the firing temperature results in severe vitrification between
the framework and the veneering ceramic, which may lead to cracks later.
– Reducing the firing temperature will result in an underfired ceramic, which is very brittle and thus susceptible to
delamination.
– Depending on the working habits, the glaze and stain firing procedures may also be conducted with a temperature
increase rate of 60 °C / 108 °F per minute.
– If a vacuum pump is available, the stain and glaze firing procedures may also be carried out with a vacuum in place.
– Restorations supported with a firing pillow on the honey-comb tray are exposed to less heat due to their lower position
in the firing chamber. In order to achieve a true-to-nature gloss nonetheless, it is recommended to extend the holding
time from 1 minute to 2 minutes.
– The parameters specified in these Instructions for Use are coordinated with the Ivoclar Vivadent ceramic furnaces
(tolerance range ± 10 °C / 18 °F).
– If a non-Ivoclar Vivadent furnace is used, temperature corrections may be necessary.
CAD – General Information

IPS Empress
– The indicated firing parameters represent standard values applicable to the current ceramic furnaces from Ivoclar
Vivadent. The indicated temperatures also apply to furnaces of older generations, e.g. P20, P90, P95, P80, P100, P200.
However, the temperatures may deviate by ± 10 °C / 18 °F, depending on the age of the heating muffle.
– If a non-Ivoclar Vivadent furnace is used, temperature corrections 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 temperatures necessary.
