Nearly 20 years ago, IPS Empress revolutionized the processing of ceramic and thanks
to its many advantages, such as aesthetics, 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 all-ceramics. In order to supply the "benchmark" for this
technology as well, the future IPS Empress System will comprise products for both
processing technologies. You will be able to benefit from roughly 20 years of clinical
experience and convincing aesthetics, 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 technology. Both products consist of the highly aesthetic,
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
aesthetic appearance. They may thus be used for the fabrication of fully anatomic
single-unit restorations, such as inlays, onlays, veneers, and crowns.

Both products may subsequently be stained and/or glazed using IPS Empress

Universal Shades/Stains, or individually veneered using the IPS Empress Esthetic
Veneer layering ceramic.

In this way, the IPS Empress System will remain synonymous for highly aesthetic, fully
anatomical all-ceramic restorations, irrespective of the processing technology.

IPS

Material

IPS Empress CAD is used for the fabrication of highly aesthetic, fully
anatomical single-unit 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. Subsequently,
the restorations may be stained using IPS Empress Universal Stains
and/or veneered using IPS Empress Esthetic Veneer.

Uses

Indications

IPS Empress CAD blocks can be used for the following adhesively cemented restorations. Depending on
the type and size of the restoration, the respective HT (High Translucency), LT (Low Translucency), or
Multi Block is recommended. IPS Empress CAD restorations may be cemented either polished,
stained/glazed, or veneered.

For further processing of IPS Empress CAD restorations, users have the following options:
– Aesthetic characterization and glazing of fully anatomical restorations using IPS Empress Universal

Shades, Stains, and Glaze pastes.

– Aesthetic veneering in the incisal third of reduced restorations (veneers and anterior crowns) using

IPS Empress Esthetic Veneer materials

Contraindications

– Bridge reconstructions
– Conventional cementation
– Very deep, subgingival preparations
– Patients with severely reduced residual dentition
– Bruxism
– Fully (circularly) veneered anterior and posterior crowns using IPS Empress Esthetic Veneer

Important processing restrictions

Failure to observe the following restrictions may compromise the success achieved with IPS Empress CAD:
– The fully anatomical IPS Empress CAD restorations must not fall below the required minimum

thickness

– The reduced (cut-back) IPS Empress CAD restorations must not fall below the required minimum

thickness
– The maximum layer thickness of IPS Empress Esthetic Veneers layering materials must not be exceeded
– IPS Empress CAD restorations must not be stained using materials other than IPS Empress Universal

Shades, Stains, and Glaze
– Powder materials must not be mixed with paste materials
– The blocks must not be milled in a non-compatible CAD/CAM system

Side effects

If patients are known to be allergic to any of the ingredients of IPS Empress CAD, the material should
not be used.

Block concept

IPS Empress CAD Blocks

The shading and translucency control of the IPS Empress CAD Blocks is based on a newly developed translucency concept
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 convince 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.

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 convince 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.

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 aesthetics and naturalness. In
conjunction with the flexible positioning of the restoration within the block, the true-to­nature opacity and translucency gradient enables a multitude of aesthetic 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 aesthetic restorations are fabricated in an easy way.

Preparation guidelines and minimum thicknesses

Successful results with IPS Empress CAD can only be achieved if the guidelines below and minimum layering thicknesses
are strictly observed. The following minimum thicknesses are required for IPS Empress CAD restorations.

Inlays and Onlays

Static and dynamic antagonist contacts must be taken into consideration. The preparation margins must not be located on
centric antagonist contacts.
A preparation depth of at least 1.5 mm and an isthmus width of at least 1.5 mm must be observed 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, marginal ridge contacts should be avoided. 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.

Provide at least 2 mm of space in the cusp areas. The shoulder must 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. The incisal preparation margins should not be located
in the area of the abrasion surfaces or dynamic occlusal surfaces. By preparing orientation grooves using a depth marker,
controlled enamel reduction can be achieved. Dissolution of the proximal contacts is not required.

For preparations without involving reduction of the incisal edge (only labial reduction), the preparation depth in the
cervical area should be at least 0.6 mm and at least 0.7 mm in the labial area.
For preparation involving reduction of the incisal edge (labial/incisal reduction), the preparation depth in the cervical
area should be at least 0.6 mm, and at least 0.7 mm in the labial area. The incisal edge must be reduced 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.

Anterior and posterior crowns

The anatomical shape is evenly reduced while observing the given minimum thicknesses. A circumferential shoulder is
prepared with rounded inner edges or a chamfer. The width of the circular shoulder should be at least 1 mm. The
incisal/occlusal third is reduced by 2 mm. For anterior crowns, the labial and/or palatal/lingual part of the tooth should be
reduced by at least 1.5 mm. The incisal width of the preparation should measure at least 1 mm (milling tool geometry) in
order to permit optimum milling of the incisal edge during CAD/CAM processing.

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:
– Die shade
– Shade of the ceramic block
– Shade of the layering ceramic
– Shade of the cementation material

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 all-ceramic 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.

20

Cementation

For cementation, the IPS Empress CAD restoration must be conditioned. For this
purpose, the completed restoration is etched with IPS Ceramic Etching Gel and
subsequently silanated using Monobond-S.

Total Etch

For the preparation of adhesive cementation with Variolink II/
Variolink Veneer, Total Etch is used. 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.

The 2-in-1 technique is suitable for efficient glazing and staining of inlays, onlays, and partial crowns. In this technique, the
glaze and stain firing is conducted in one single step. This technique does not permit as many shade adjustments as a
separate stain firing. If more intensive and extensive shade adjustments are desired, we recommend conducting a separate
stain and characterization firing (as described in the following chapter).

IPS Empress CAD Inlays / Onlays – stained/glazed

Please refer to the corresponding Operating Instructions and/or Manuals of the respective CAD/CAM system
for further information on the CAD/CAM processing procedure. The instructions by the manufacturer must be
observed.

Finishing and preparing for stain and glaze firing

For finishing glass-ceramics, appropriate grinding instruments are indispensable. If the
wrong grinding instruments are used, marginal chipping and local overheating my 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.
– Overheating the glass-ceramic must be prevented.
– Smooth out attachment point of the holder and take the proximal contact points into

account.
– Carry out individual shape adjustments, if required.

Before the stain and glaze firing, the restorations must be free of dirt and grease. Avoid any
contamination after cleaning. Observe the following procedure.
– Clean the restoration with ultrasound in a water bath or blast with Al2O3at 0.5 bar

pressure (Caution: abrasive) and clean under running water or using the steam jet.
– Certain blasting devices require different settings for the intended blasting procedure.

2-in-1 Technique – Stain and glaze firing using IPS Empress Universal

Once the restoration has been cleaned, apply the stains and glazing material in 2 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 Glazing 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.
– Too thin glazing material layers result in an unsatisfactory gloss.

Smooth out attachment point and take proximal contacts into account.

23

Step 2 – Application of Shades / 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 Shades.
– 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.

After glazing and staining, the glaze and stain firing is conducted in a compatible ceramic furnace (e.g. P500).
The following points should be observed when placing the restoration in the furnace and setting the firing parameters:
– Support inlays, onlays, and partial crowns with a firing pillow and place them on a 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 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.

Therefore, in order to achieve a true-to-nature gloss, 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. Keep firing pillows used for all-ceramic materials

separated from those for metal-ceramics to avoid cross-contamination.

25

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 Shades 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.

IPS Empress CAD Veneers / Crowns – stained/glazed

Please refer to the corresponding Operating Instructions and/or Manuals of the respective CAD/CAM system
for further information on the CAD/CAM processing procedure. The instructions by the manufacturer must be
observed.

Finishing

For finishing 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)
– Overheating the glass-ceramic must be prevented.
– Smooth out 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.

Optional

Die fabrication using IPS Natural Die Material

The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. Fabricate a control die of the selected
shade. This control die supports the optimum shade adaptation of the restoration to reproduce 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 aspects of the restoration using the

IPS Condenser and adapt so that the entire inner aspect 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 for 60 seconds.

– After polymerization, the die can be finished and or smoothed, if

required.

The control die made of IPS Natural Die Material is the optimum basis

for a true-to-nature all-ceramic restoration.

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 fully anatomical anterior crown or the veneer are first designed according to the definite
final shape. After that, the incisal third is reduced and subsequently provided with an individualized aesthetic veneer.

Finishing and preparing for stain and glaze firing

Before the stain and glaze firing, the restoration has to be finished as follows:
– Finish the restoration using diamonds and give it a true-to-nature shape and surface structure, such as growth lines and

convex/concave areas.
– The surface structure may have to be worked out more strongly, since it has been weakened by the glazing procedure.
– The areas that are not covered with layering ceramic have to be smoothed out and prepolished using silicone disks in

order to obtain an even gloss on the surface after glaze firing.

36

Clean restoration with ultrasound in a water bath or using the steam jet. Evenly apply the glazing material to the entire outer surfaces of the restoration.

Apply the mixed Shades directly into the unfired glazing material layer. Completely layered IPS Empress CAD crown and veneer fabricated in the cut-back technique.

Stain and glaze firing with IPS Empress Universal

The stain and glaze firing is carried out using IPS Empress Universal Shade, Stains, and Glaze material. Depending on the
situation, they can be conducted together or one after the other (see pages 22–24 for further details). Before the stain and
glaze firing, the restoration must be free of dirt and grease. Any contamination after cleaning must be prevented.
The following working procedure should be observed:
– Before staining and glazing, clean the restoration with ultrasound in a water bath or using the steam jet.
– To check the shade, wet the inner aspects of the restoration with IPS Empress Universal Glaze and Stain Liquid, position

the restoration on the control die, and check shade and effects.
– Extrude IPS Empress Universal Glazing 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 a little thicker on areas that are not covered with layering ceramic. In this way, an even gloss

can be achieved.
– 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.
– To intensify the dentin shade in the cervical and central crown third, mix the corresponding Shade material and apply it

directly into the unfired glazing material layer.
– Place veneers and anterior crowns on the honey-comb firing tray with the help of metal pins. Additionally support the

veneers with a small amount IPS Object Fix.

restoration using the steam jet.
– Mix IPS Empress Add-On 770 °C / 1418 °F to a workable consistency. Make sure that the add-on material and liquid are

evenly mixed so that an optimum firing result can be achieved.
– Apply the mixed add-on material on the cleaned, desired areas using a brush and slightly blot them with an absorbent

cloth.
– Position the adjusted restoration on the firing tray and fire in the ceramic furnace.
– After firing, manually polish the supplemented areas to a high gloss.

General Information

IPS

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 working procedure should be observed:

– Leucite-reinforced glass-ceramic materials are generally etched with IPS Ceramic Etching Gel and subsequently silanated

using Monobond-S.

Preparing for cementation

IPS Empress CAD

Indication Veneers, inlays, onlays, partial crowns, anterior and posterior crowns

Cementation method Adhesive cementation

Etching of the restoration 60 seconds, using IPS Ceramic Etching Gel

Conditioning / Silanating

Monobond-S

of the restoration

Cementation system Variolink II or Variolink Veneer

Multilink Automix

Conventional cementation and blasting of finished IPS Empress CAD restoration is contraindicated!

39

Firing of 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 may also be used.

- The firing temperatures must be observed at all times. Increasing the firing temperature will result in severe vitrification
between the framework and the veneering ceramic, which may lead to crack formation later on.

- 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 firing parameters specified in this Instructions for Use are coordinated with the Ivoclar Vivadent ceramic furnaces
(tolerance range ±10 °C/18°F).

– If furnaces other than those from Ivoclar Vivadent are used, temperature adjustments may be necessary.

Firing parameters

– These firing parameters represent standard values applicable to the ceramic furnaces from Ivoclar Vivadent.The

temperatures indicated also apply to furnaces of older generations,e.g. P20, P90, P95, P80, P100, P200. 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.
– 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.
