Your purchase of IPS e.max means you have chosen more than simply an all-ceramic

system. You have taken the decision to benefit from the unlimited possibilities of all-

ceramic. IPS e.max delivers high strength and highly aesthetic materials for the PRESS

and the CAD/CAM technology.

The IPS e.max products are unique. They are recognized for their outstanding

properties as well as exceptional versatility and flexibility – and they produce results

with maximum aesthetics.

The components for the PRESS technique include the highly aesthetic glass-ceramic

IPS e.max Press ingots and the glass-ceramic IPS e.max ZirPress ingots for pressing onto

zirconium oxide. Depending on the case requirements, two types of materials are

available for CAD/CAM techniques: the innovative IPS e.max CAD glass-ceramic blocks

and the high-strength zirconium oxide IPS e.max ZirCAD.

The IPS e.max System is further enhanced by the nano-fluorapatite layering ceramic

IPS e.max Ceram, which is used as a veneering material for all the IPS e.max

components – either glass-ceramics or zirconium oxide ceramics.

This proves that really exceptional all-ceramic systems are well designed. The system

allows you to take advantage of a single, standardized layering scheme to offer your

dentists and their patients restorations with maximum individuality and naturalness.

IPS e.max ZirPress is a fluorapatite glass-ceramic ingot for the PRESS-

ON technique. The fluorapatite crystals contained in the material are

of different sizes and therefore

selectively control the relationship

between translucency, opalescence

and brightness of the restorations.

Consequently, complete masking of

the less translucent zirconium oxide

frameworks is achieved. The PRESS-ON technique allows you to take

advantage of the benefits of the PRESS technique (accuracy of fit)

and CAD/CAM processing (milling of zirconium oxide). IPS e.max

ZirPress can be pressed onto both IPS e.max ZirCAD single tooth

copings and multi-unit bridge frameworks. Very little time and effort

is required to press the IPS e.max ZirPress ingots onto the frame-

works or copings using the proven PRESS technique. The ingots can

either be used to create a fully anatomic restoration or a dentin core

(cut-back). Frameworks onto which IPS e.max ZirPress has been

pressed demonstrate precision, heat resistant ceramic shoulders.

The restorations can be either characterized or veneered with the

efficient IPS e.max Ceram material. The superior aesthetic and

functional restorations achieved with these materials are cost-

effective and fully satisfy individual patient requirements.

Can IPS e.max ZirPress also be pressed onto other zirconium

oxide frameworks?

IPS e.max ZirPress can be pressed onto frameworks made of sintered

zirconium oxide or HIP zirconium oxide as well as presintered

zirconium oxide in the CTE range of 10.5–11.0 x 10-6 K-1

(100–500 ºC). The following zirconium oxides have been tested for

this purpose:

– KaVo – Bio ZS (coloured and uncoloured) and Bio ZH Blanks

– Nobel Biocare – Procera Zirconia

– DeguDent – Cercon Base

– 3M/Espe – Lava Frame (coloured and uncoloured)

– DCS – DC-Zirkon

– Digident – Digizon

– Cad.esthetics – Denzir

– Vita – In-Ceram 2000 YZ Cubes (coloured and uncoloured)

– Diatomic – Diadem/Diazir (coloured and uncoloured)

– Wieland – Zeno Zr Disc

Can IPS e.max ZirPress be pressed onto implant abutments?

IPS e.max ZirPress can be pressed onto zirconium oxide abutments

in the CTE range of 10.5–11.0 x 10-6 K-1 (100–500 ºC). The

abutments should not be too small and they must provide adequate

support for the shape and cusps. The instructions of the individual

manufacturers should be observed.

Can IPS e.max ZirPress be used to fabricate single crowns

without zirconium oxide copings?

IPS e.max ZirPress has been developed for the press-on technique.

The strength of the ingots is not sufficient for crowns without

zirconium oxide copings. Therefore, the ingots can not be used for

this indication.

Can IPS e.max ZirPress be used to fabricate inlays and onlays?

IPS e.max ZirPress has been developed for pressing onto zirconium

oxide. Therefore, the shades have been specially developed for this

application. From a materials science point of view, inlays and onlays

can be fabricated using this material. However, the aesthetic

potential of the product is limited because of the opacity of the

ingots. This must be taken into consideration during fabrication.

Can IPS e.max ZirPress be pressed onto only a part of a resto-

ration (eg on a shoulder or pontic)?

IPS e.max ZirPress can be pressed onto selected parts of a restora-

tion, if the instructions for use, the necessary minimum thickness of

the ceramics and the following points are observed. The sprues

must be attached directly, for example, to the ceramic shoulder.

During spruing and placement on the IPS e.max ring base, adequate

stability of the restoration and the waxed up areas must be ensured.

The fired ZirLiner areas which remain free from the pressed material

must not come in contact with the investment material, to prevent

the formation of bubbles during the subsequent firing procedures.

Therefore, the fired ZirLiner must be coated with a thin layer of wax.

This layer prevents the liner from coming in contact with the

investment material and also makes divestment easier, as the

investment material peels off without blasting. The removal of the

reaction layer with Invex Liquid does not have a negative influence

on ZirLiner. The ZirLiner surface must be protected in the final bla-

sting process in which the reaction layer is completely removed with

Al2O3. Wash (foundation) firing has to be carried out, even if

ceramics are only pressed onto certain areas of the restoration to

improve wetting.

Can veneers be fabricated with IPS e.max ZirPress?

IPS e.max ZirPress has been developed for pressing onto zirconium

oxide and the shades of the material have been adjusted for this

purpose. However, from a technical point of view, veneers can be

fabricated with this material. For example, if veneers are required in

the anterior region for a large restorative case and if the shade of

the IPS e.max ZirPress ingot corresponds to the demands of the

patient, veneers can be pressed (in the same investment ring).

The cut-back technique allows the veneers to be individually

characterized with IPS e.max Ceram. Veneers made with IPS e.max

ZirPress must be placed with the adhesive technique.

Can IPS e.max ZirPress be pressed onto inlay-retained bridges?

IPS e.max ZirPress LT ingots can be pressed onto zirconium oxide

inlay-retained bridges. In the creation of the zirconium oxide frame-

work, the minimum thickness of the connectors and the inlays

(min 0.5 mm) must be observed. All the areas at the preparation

margins should be fabricated with IPS e.max ZirPress rather than

zirconium oxide, since the press ceramic can be etched. This allows

a sound bond to be established between the press ceramic, the

luting composite and the prepared tooth.

Can IPS e.max ZirPress be pressed onto IPS Empress

CosmoPost?

IPS e.max ZirPress ingots can be pressed onto IPS Empress

CosmoPost. An excellent bond is achieved. Because of the large

selection of IPS e.max ZirPress ingots, very natural-looking

restorations are achieved.

Can IPS e.max ZirPress be pressed onto glass-ceramic

frameworks made of IPS e.max Press or IPS e.max CAD, for

example?

IPS e.max ZirPress ingots can only be pressed onto zirconium oxide

materials. The press temperature of 910–915 ºC (1670–1679 °F) is

too high for glass-ceramic frameworks. Consequently, they would

become deformed during the press procedure.

Q U E S T I O N S A N D A N S W E R S

What is the purpose of the IPS e.max Ceram ZirLiner?

IPS e.max Ceram ZirLiners are translucent. Their three major

purposes are as follows:

1. They enable a strong, homogeneous bond with the zirconium

oxide framework.

2. They provide the white, non-coloured zirconium oxide frame-

works with chroma, an in-depth effect, and a shaded character

without increasing their opacity

3. They also provide the non-fluorescent zirconium oxide frame-

work with a natural fluorescence, thus enabling the fabrication

of lifelike restorations

Which type of IPS e.max Ceram ZirLiner should be used on

shaded zirconium oxide frameworks?

The clear IPS e.max Ceram ZirLiner should be used on shaded

zirconium oxide frameworks. The transparent character of the

IPS e.max Ceram ZirLiner does not affect the framework shade.

An outstanding bond as well as natural-looking fluorescence is

achieved. When shaded frameworks are used, the colour

compatibility of the IPS e.max ZirPress ingots and that of the

framework must be ensured.

Can IPS e.max ZirPress be pressed onto zirconium oxide

frameworks without the application of IPS e.max Ceram

ZirLiner?

A suitably shaded IPS e.max Ceram ZirLiner must always be applied

before waxing up. The IPS e.max Ceram ZirLiner generates an

outstanding bond and gives the restoration an effect of depth with

regard to the colour and fluorescence.

Why is the IPS e.max Ceram ZirLiner powder green and how

should it be applied?

Since zirconium oxide is white and, therefore, shows a poor contrast

to tooth-coloured and/or white powders, the IPS e.max ZirLiner was

given an identification colour to render its application more simple

and efficient. The IPS e.max Ceram ZirLiner consists of a very fine

powder and appears somewhat thick due to the dense packing of

the grains. Make sure that the material is applied in an even,

greenish coat. If the shade is too pale, the layer is too thin. After

firing, however, the ZirLiner demonstrates a layer thickness of

approximately 0.1 mm.

How thick should the wax-up be?

The wax-up should be at least 0.7 mm thick all over. If the wax is

not at least this thick, the restoration may not be completely

covered with the pressed ceramic and deviations in the shade may

occur.

Can IPS Empress Universal Shades, Stains and Glaze be used

with IPS e.max ZirPress?

IPS Empress Universal Shades, Stains and Glaze have been specially

developed for the IPS Empress system. Consequently, they cannot

be used with IPS e.max products.

Can IPS e.max Alox plungers also be used for IPS Empress?

IPS e.max Alox plungers are exclusively for the IPS e.max System and

the corresponding investment ring system specifically developed for

this purpose. Since the diameter has been increased, the Alox

plunger would not fit into the IPS Empress investment ring system.

Can the IPS e.max Alox Plunger Separator also be used for

other pressed ceramics, such as IPS Empress Esthetic?

The IPS e.max Alox Plunger Separator can only be used for

IPS e.max Press and IPS e.max ZirPress ingots, since the press

temperature of the IPS Empress Esthetic ingots of 1075 °C (1967 °F)

is too high and results in the Separator losing its effect.

Can other press furnaces be used to press IPS e.max ZirPress

ingots?

IPS e.max ZirPress is specifically coordinated with the Ivoclar

Vivadent press furnaces (EP 500, EP 600, and EP 600 Combi). If

other press furnaces are used, the parameters have to be adjusted

accordingly by the user.

Can IPS e.max ZirPress restorations also be conventionally

cemented?

IPS e.max ZirPress restorations may be either adhesively or

conventionally cemented. For conventional cementation, however,

an appropriately retentive preparation design must be observed. If

this is not possible, adhesive cementation, e.g. with Multilink®

should be used. Vivaglass® CEM is available for conventional

cementation. We advise against the use of traditional phosphate

cements, since they negatively influence the light transmission

through the all-ceramic and compromise the aesthetic appearance

of the all-ceramic restorations.

The shading and opacity control of the IPS e.max ZirPress ingots is based on a newly

developed, translucency/opacity concept. The system is flexibly organized and can be

used with both A–D and Chromascop shades. The individual levels of the concept are

determined by indications and application. The individual opacity and translucency

levels are distinguished by means of a colour code.

I N G O T C O N C E P T

Low Translucency

IPS e.max ZirPress MO (Medium Opacity)

These ingots are available in the nine most popular A–D shades as well as in the

lightest Chromascop Bleach shade. Because of their opacity, they are ideal for

situations in which a dentin core is pressed onto IPS e.max ZirCAD frameworks. The

combination of the fluorescence of the IPS e.max Ceram ZirLiner and the fluorapatite

crystals of the ingots produces an outstanding bond and an ideal shade base. The

ingots exhibit natural dentin-like fluorescence. After the ceramic has been pressed

onto the framework, the incisal third of the restoration is characterized with ease

using the IPS e.max Ceram Incisal and Impulse materials. As a result, little effort is

required to create highly aesthetic zirconium oxide-reinforced restorations using the

proven cut-back technique.

IPS e.max ZirPress LT (Low Translucency)

These ingots are available in the nine most popular A-D shades as well as the lightest

Chromascop Bleach shade. Because of their translucency, they are ideal for pressing a

fully anatomic ceramic layer onto IPS e.max ZirCAD frameworks. In combination with

the fluorescent IPS e.max Ceram ZirLiners, an outstanding bond to the framework is

created. The IPS e.max Ceram Intensive ZirLiners are used to apply characterizations

before the ceramic material is pressed onto the framework. Therefore, the restorations

obtain a natural-looking effect of depth. Furthermore, the ingots exhibit lifelike

fluorescence in the incisal aera. The restorations are subsequently characterized with

IPS e.max Ceram Shades and Essence materials. If necessary, contacts or similar

features can be built up with IPS e.max Ceram layering materials.

IPS PressVEST Investment Material IPS PressVEST is an optimized, phosphate-bonded investment

material for the conventional heating method (overnight). It produces

pressings that fit accurately and can be used with the following

Ivoclar Vivadent pressed ceramics to be pressed in the EP 500,

EP 600, and EP 600 Combi press furnaces:

– IPS e.max Press

– IPS e.max ZirPress

– IPS Empress Esthetic

– IPS Empress 2

– IPS Empress Cosmo

IPS PressVEST cannot be used for metal casting or the IPS Empress

layering technique material, due to the high temperatures.

IPS e.max Alox Plunger The ceramic ingot, in its softened state, is pressed into the hollow

space in the investment ring by means of the IPS e.max Alox plunger.

It features a larger diameter and is slightly shorter than the existing

IPS Empress Alox plunger and is thus only suitable for the IPS e.max

investment ring system. Both ends of the Alox plunger are rounded,

which makes both sides suitable for pressing. In this respect, the

new plunger is different from the existing IPS Empress press

plungers.

Delivery form:

IPS e.max Alox Plunger

– 2 IPS e.max Alox Plungers

IPS e.max Alox Plunger Separator The IPS e.max Alox Plunger Separator prevents the ingot from

sticking to the Alox plunger during pressing and cooling in the

investment ring. The cold Alox plunger is inserted into the recess

and rotated. The powder adheres to the surface and thus forms a

separating layer. A very small amount of Separator is sufficient. The

cold, prepared Alox plunger is subsequently inserted into the pre-

heated investment ring immediately before pressing.

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

Chromascop

The Chromascop shade guide provides the shade standard

for Ivoclar Vivadent products. The individual shades of the

Chromascop are logically arranged and therefore allow shades

to be determined accurately and efficiently. The 20 shades are

divided into five shade groups. In addition, the Chromascop Bleach

shade group comprises four very light shades. Once the basic hue

has been established, the most suitable shade is chosen from within

the shade group. All superfluous effects (eg cervical and translucent

areas, severe discolourations in the incisal area and dentin as well as

superficial characterizations) have been left out, making the selection of

the proper shade much easier.

IPS Natural Die Material Shade Guide

In order to facilitate the reproduction of the tooth shade, dentists have the

possibility of communicating the shade of the preparation of the given

clinical situation to the dental laboratory using the IPS Natural Die

Material shade guide. In this way, the fabrication of all-ceramic

restorations is facilitated and a patient's individual characteristics

can be taken into consideration.

Successful results can only be achieved with IPS e.max ZirPress if the guidelines and framework thicknesses of

IPS e.max ZirCAD are strictly observed.

Single crowns and 3-unit bridges

Evenly reduce the anatomical shape and observe the stipulated minimum thicknesses. Prepare a circular shoulder with

rounded inner edges or chamfer with an angle of approx. 10° - 30 °. The width of the circular shoulder/chamfer is approx.

1 mm. Reduction of the crown third – incisal or occlusal by about 1.5 mm. For anterior crowns, the labial and palatal/

lingual part of the tooth should be reduced by about approx. 1.2 mm. The incisal edge of the preparation should be at

least 1 mm (milling tool geometry) in order to permit optimum milling of the incisal area during CAD/CAM processing.

F R A M E W O R K D E S I G N C R I T E R I A

The framework design is the key to the success of durable all-ceramic restorations. The

more attention given to framework design, the better the final results and the

clinical success will turn out to be. The following basic guidelines have to be observed:

– The framework material is the high-strength component of your restoration

and should, therefore, be designed in such a way that it supports the shape

of the restoration and the cusps. Reinforcements and supports have to be

built up using the corresponding tools of the respective software.

– In large preparations, the excess in available space must be compensated by

the design of the framework and not by the layering material.

– If possible, the connector design should be extended in the vertical direction,

rather than in the sagittal or horizontal direction.

– It is not always possible to establish the necessary connector dimensions with

regard to the sagittal (linguo-vestibular) region. In these cases, the connector

dimensions must always be increased in the vertical (inciso-cervical) direction.

– Reducing the framework thickness is always related to a reduction in

strength.

– The integrated parameters in the software are basic recommendations. Depending

of the overall thickness of the restoration it can be necessary to adjust the

parameters.

For the cementation of the IPS e.max restorations, you may select between the tried-and-tested adhesive

luting composites and cements from the coordinated assortment of Ivoclar Vivadent. Adhesive

cementation achieves a sound bond between the preparation and the cementation material, while

conventional cementation requires a retentive preparation to ensure the durability of the IPS e.max

restorations.

Preparation of the framework and application of ZirLiner

The sintered IPS e.max ZirCAD framework is tried in on the model. The margins can be trimmed up to the inner edge of

the chamfer or shoulder preparation to make room for the pressed ceramic shoulder. After the adjustments have been

made, the framework must still exhibit the required minimum thickness. The following procedure should be followed:

– Before the veneering procedure, the framework must be cleaned under running water

or with steam.

– The framework must not be blasted with Al2O3, as this would damage its surface.

– Before contouring begins, IPS e.max Ceram ZirLiner must be applied to generate a

strong bond and create the effect that the shade and fluorescence of the restoration

come from deep within.

– If a ceramic material is directly pressed onto ZirCAD frameworks without using ZirLiner,

the bond created is very weak and cracks and delamination are likely to occur.

– Subsequently, IPS e.max Ceram ZirLiner in the desired shade is mixed to a creamy

consistency with the matching liquid.

– If another type of consistency is desired, IPS e.max Ceram Build-Up Liquids (allround

and soft) as well as the IPS e.max Glaze and Stain Liquids (allround and longlife) can be

used. The liquids may also be mixed with each other in the required ratio.

– IPS e.max ZirLiner is applied until it fully covers the framework. Care must be taken at

the margins. If necessary, the restoration may be vibrated until an even greenish colour

is achieved. If the colour is too pale, the increment is too thin.

– For areas requiring stronger colours, four IPS e.max Ceram Intensive ZirLiners (yellow,

orange, brown, incisal) are available.

– Next, the applied ZirLiner is briefly left to dry and then fired.

– IPS e.max Ceram ZirLiner should demonstrate a thickness of 0.1 mm after firing.

Wax-up

The wax-up must be fabricated using wax that fires without leaving any residue. The cut-back technique is conducted as

follows:

– The stone die is isolated with a conventional plaster-wax separator

– Calipers are used to measure and record the thickness of the ZirCAD framework at various points.

– The ZirCAD framework onto which IPS e.max Ceram ZirLiner has been fired is weighed and the weight recorded. Once

the wax-up has been made, this data is used to determine the wax weight.

– Subsequently, the framework is secured in the correct position on the die. The margins are attached with wax first.

– A fully anatomic wax-up is created in the usual way and a silicone matrix is made.

– The waxed-up framework can be reduced at this stage. Alternatively, the framework can be pressed to full contour and

then reduced by grinding.

– If the wax-up is reduced, the incisal layer has to be trimmed selectively. A wax thickness of 0.7 mm must be observed to

avoid incomplete press results.

Sprueing

Always place the sprues in the direction of flow of the ceramic and at the thickest part of the wax-up in order to achieve

unimpeded flow of the viscous ceramic material. The 100 g or 200 g investment ring base is selected depending on the

number of objects to be invested. Bridges must be pressed using the 200 g investment ring system. The following sprueing

guidelines must be observed:

Investing

Investing is carried out with either IPS PressVEST (e.g. over night) or IPS PressVEST Speed (during the

day). The corresponding IPS silicone ring with matching ring gauge is used for that purpose. We

recommend the following procedure to determine the accurate wax weight:

– Weigh the ring base (seal the opening of the ring base with wax).

– Position the objects to be pressed on the ring base and attach them with wax. Weigh again.

– The wax weight is calculated by subtracting the weight of the ring base and the ZirCAD framework

from the total weight.

Small Ingot 2 small ingots

Wax weight up to max. 0.75 g up to max 2 g

Investment Ring System 100 g and 200 g 200 g only

Please refer to the Instructions for use of the corresponding investment material regarding the detailed

processing parameters.

– Do not apply a debubblizer to the wax objects.

– Mix investment material. The investment material contains quartz powder. Therefore, the inhalation of

dust must be avoided.

– Use a suitable instrument for the fine investment of the cavity. Make sure that the delicate wax

margins are not damaged.

– Carefully position the IPS Silicone Ring on the investment ring base without damaging the wax

objects. The IPS Silicone Ring must sit flush on the investment ring base.

– Subsequently, carefully fill the investment ring with investment material up to the marking and

position the ring gauge with a hinged movement.

– Allow the investment material to set without manipulating the investment ring.

– Do not use IPS PressVEST for investment over the weekend to prevent crystallization.

Use the IPS Silicone Ring for investment.

Fill investment ring up to the marking and position the ring gauge with a hinged movement.

23

Preheating

After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the

investment ring is prepared for preheating as follows:

– Remove the ring gauge and ring base with a turning movement,

– Carefully push the investment ring out of the IPS Silicone Ring.

– Remove rough spots on the bottom surface of the investment ring with a plaster knife and check the 90° angle.

– Investment material residue must not enter the sprues. Blow into the sprues if necessary.

– If several investment rings are preheated together, mark them with the respective ingot shade.

Calibration

The furnace must be regularly calibrated to achieve optimum press results. Calibrate the EP500 with the

Temperature Checking Set 2 and the EP600 with the Automatic Temperature Checking Set 1.

EP 500

1. Switch on the EP500 and allow the furnace to heat up to the stand-by-temperature of 700 °C/

1292 °F. Hold this temperature for at least 30 minutes.

2. Select a program for the staining technique T=1075 °C/1967 °F. Run the program with the furnace

empty. After activation of the holding time H=20 min., which the EP500 does automatically,

interrupt the program after 15 minutes (set timer) by pressing the STOP key twice.

If you fail to interrupt the program, the ER16 error message appears. Rectify this error by following

the instructions given on the corresponding list of error messages. Allow the furnace to cool until

the stand-by-temperature of 700 °C/1292 °F has been reached with the furnace head closed. Hold

this temperature for at least 30 minutes.

3. Place the calibration set on the honey-combed firing tray in order to ensure the appropriate height

(temperature range) in the furnace.

4. Conduct the calibration using the Temperature Checking Set 2.

EP 600

1. Place the melting sample in the ceramic base.

2. Tighten the contact pin to secure the melting sample.

Important: Do not use tweezers or tongs. Apply slight pressure to secure the melting sample in

place.

3. Select the calibration program in the 'Miscellaneous' menu. The furnace head opens.

4. Remove the firing plate from the furnace and place it on the cooling plate using the firing tongs.

5. Place the calibration tray in the holes for the Automatic Temperature Checking Set ATK 1 in the

Pressing

Before the preheating cycle for the investment ring has ended, the following preparations for pressing must

be carried out:

– Provide a cold IPS e.max Alox Plunger and a cold IPS e.max ZirPress ingot in the desired shade.

– After that, dip the cold IPS e.max Alox plunger into the opening of the IPS e.max Alox Plunger Separator

and keep ready for use.

– Select the press program for IPS e.max ZirPress.

Once the preheating cycle has been completed, remove the investment ring from the preheating furnace

and proceed as follows. Make sure that you take no more than 1 minute for these steps to prevent the

investment ring from cooling down too much.

– Insert the cold IPS e.max ZirPress ingot into the hot investment ring.

– Insert the ingot with the rounded, non-imprinted side into the investment ring. The imprinted side should

face upward to double-check the ingot shade.

– Place the powder-coated cold IPS e.max Alox plunger into the hot investment ring.

– Place the completed investment ring at the center of the hot press furnace using the investment tongs.

– Press START to start the selected program.

Select a cold isolated IPS e.max Alox Plunger and a cold IPS e.max ZirPress ingot in the desired shade.

Divesting

After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks.

These cracks developed (immediately around the Alox plunger) during cooling as a result of the different

CTEs of the various materials (Alox plunger, investment material, and pressed materials). They do not

compromise the press result.

Divest the investment ring as follows:

– Mark the length of the Alox plunger on the cooled investment ring.

– Separate the investment ring using a separating disk. This predetermined breaking point enables reliable

separation of the Alox plunger and the ceramic material.

– Break the investment ring at the predetermined breaking point using a plaster knife.

– Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure.

– Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure.

– Do not use Al2O3 for rough or fine divestment

– When divesting the object, blast from the direction indicated in the schematic below and observe the

appropriate distance in order not to damage the object margins.

– Any ceramic residue on the Alox plunger is removed with Al2O3 (type 100 microns).

Separate the investment ring using a separating disk and break it at the predetermined breaking point

Mark the length of the Alox plunger

Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure until the restoration is visible.Fine divestment is conducted at 2 bar (30 psi) pressure.

28


After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max

Press Invex Liquid followed by blasting. The procedure is carried out as follows:

– Pour the Invex Liquid into a plastic cup.

– Immerse the pressed objects into the Invex Liquid and clean in an ultrasonic cleaner for at least

5 minutes and a maximum of 10 minutes. Make sure that the objects are completely covered with

Invex Liquid.

– Subsequently clean the object under running water and blow dry.

– Carefully remove the white reaction layer using Al2O3 Type 100 at 1–2 bar (15–30 psi) pressure.

– Make sure that the reaction layer is completely removed, both on the cavity side and on the outer side

of the object (repeat the procedure, if necessary).

– If the reaction layer is not entirely removed, bubbles may develop, which may lead to bonding

problems or even cracks in the layering ceramic.

– Replace the Invex Liquid after approximately 20 uses or after sedimentation of the liquid.

Warnings

– The Invex Liquid contains < 1 % hydrofluoric acid.

– It is harmful when inhaled, swallowed, and when it comes into contact with the skin.

Furthermore, it is corrosive.

– Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet).

– If the material comes into contact with the eyes, immediately rinse with copious amounts of water

and see a physician immediately.

– If the material comes into contact with the skin, immediately clean with soap and copious amounts

of water.

– Use suitable protective clothing, gloves, and goggles when working.

– In case of an accident or physical discomfort, see a physician immediately (bring the Invex label, if

possible).

Disposal

– Neutralize the Invex Liquid

– Neutralize the diluted solution by adding lime or baking soda and letting it react for 5 minutes.

– After the reaction time, pour the neutralized solution into the sink, flushing it with running water.

Remove the reaction layer with Invex and Al2O3 at 1–2 bar (15–30 psi) pressure.

29

Finishing

It is of critical importance to use the correct grinding instruments for finishing and adjusting glass-ceramics. If unsuitable

grinding instruments are used chipping of the edges and local overheating may occur (please see the corresponding

recommendations from Ivoclar Vivadent).

The following procedure is recommended to finish IPS e.max ZirPress frameworks:

– Wet the area to be ground and use a fine diamond disk to cut the sprues. Try the

restoration in on the model.

– Prevent overheating of the ceramic material. Low speed and light pressure is

recommended. Please observe the corresponding instructions of the manufacturer.

– Smooth out the attachment points of the sprues.

– Do not 'post-separate' the bridge framework using separating disks, since this may

result in undesired predetermined breaking points, which will subsequently compromise

the stability of the all-ceramic restoration.

– If a fully anatomic wax-up was pressed, the restoration is now cut back. Cut back the

restoration to make room for the application of the subsequent layers of Incisal and

Impulse materials. Make sure that the minimum thickness of the restoration is

maintained during the cut-back procedure.

– If a reduced version of the restoration was waxed-up, only the surface has to be slightly

adjusted. Make sure that the minimum thickness of 0.6 mm is maintained to avoid

irregularities in the shading.

– Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or

with steam before applying the veneering material.

– Some blasting machines may require different pressure settings to accomplish this

procedure.

Cut the sprues using a fine diamond disk and place the framework on the die. Use low speed and light pressure …

... to remove sprue attachment points and smooth out the surface. Finished cut back

Optional

Die fabrication with IPS Natural Die Material

The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. A control die is fabricated using the

shade information provided by the dentist (shade determination). This control die represents the optimum basis for a

true-to-nature shade reproduction of the given oral situation.

– Coat the inner surfaces of the ceramic restorations with IPS Natural Die Material Separator and allow it to react for a

short time.

– Apply die IPS Natural Die Material in the corresponding shade to the inner surfaces of the restoration using the

IPS Condenser and adapt so that the entire inner surface is coated and filled.

– Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the

holder. Make sure that the Die Material is well adapted to the restoration margins and that no gaps are present.

– Polymerize the IPS Natural Die Material die with a commercial polymerization light, e.g. Lumamat 100, for 60 seconds.

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

Veneering with IPS e.max Ceram

The following paragraphs will explain the most important veneering steps.

Detailed information about the nano-fluorapatite ceramic and its processing

are contained in the IPS e.max Ceram Instructions for Use.

Firing of zirconium oxide-supported restorations

– Several units (eg multi-unit bridges with bulky pontics) in the furnace impede even and thorough heating of the

individual units.

– Heat penetration in the firing chamber depends on the type of furnace and the size of the firing chamber.

– To achieve adequate heating of the individual restorations the heating rate should be lowered by 5–10 ºC (41–50 °F) as

well as the holding time should be extended by 30 seconds.

– The parameters listed in the Instructions for Use apply to Ivoclar Vivadent furnaces (temperature tolerance ± 10 ºC/50 °F).

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

Before the foundation is applied, the restoration must be free from dirt and oil. Once the restoration has been cleaned,

it must not be contaminated in any way. Conduct the foundation firing using Incisal or Transpa (clear, neutral)

materials or with IPS e.max Ceram Shades, Incisal Shades and Essence materials. The IPS e.max Ceram ZirLiner

must not be used. Please follow the instructions provided below:

– Use the IPS e.max Ceram Build-up Liquids (allround and soft) to mix the Incisal, Transpa and Impulse

materials. If a mouldable consistency is preferred, the IPS e.max Ceram Glaze and Stain

Liquids (allround and longlife) can be used. Apply a thin, but complete coat of

Finishing and preparation for the Stain and Glaze firing

The surface must be finished and polished as follows before the stains and glaze firing:

– Use finishing diamonds to achieve a natural shape and surface of the restoration.

– Areas that are not covered with the layering ceramic must be smoothed with silicone wheels and prepolished to obtain

an even gloss on the surface after glaze firing.

Create a natural shape and surface with finishing diamonds.

Smooth and prepolish pressed ceramic areas.

34

Stain and Glaze firing

Stain firing is conducted with Essence and Shade materials, while Glaze firing is carried out with Glaze powder or paste

according to the following steps. Depending on the situation, the firings may be conducted together or separately. The

firing parameters are identical.

– Apply a thicker layer of Glaze to the areas that are not covered with the layering ceramic than to those areas which are

covered with the ceramic. This helps to achieve an even gloss.

– If a silky-matte finish is achieved on the pressed and layering ceramic surfaces during prepolishing, the glaze has to be

applied only to the pressed ceramic areas. The layering ceramic is not over-glazed and left with its natural sheen.

– The fissures and cusps are individually characterized with the Essence materials.

Apply Glaze more thickly on the pressed ceramic areas.

– Before veneering, the framework must be cleaned under running water or with steam.

– The framework must not be blasted with Al2O3, as this would damage its surface.

– IPS e.max Ceram ZirLiner must always be applied prior to contouring in order to achieve

a sound bond, as well as an in-depth shade effect and fluorescence.

– Direct pressing on ZirCAD frameworks without using IPS e.max Ceram ZirLiner results in

a poor bond and may lead to delamination.

– Mix the IPS e.max Ceram ZirLiner in the corresponding shade with the respective liquid

to a creamy consistency.

– If a different consistency is desired, the IPS e.max Ceram Build-Up Liquids (allround

and soft) and the IPS e.max Ceram Glaze and Stain Liquids (allround and longlife) may

be used. The liquids may also be mixed with each other at any mixing ratio.

– Apply ZirLiner on the entire framework, pay special attention to the margins. If

required, the restoration may be vibrated until an even, greenish colour effect is

achieved. If the colour appears too pale, the layer is too thin.

– For more intensively shaded areas, 4 IPS e.max Ceram Intensive ZirLiners (yellow,

orange, brown, incisal) are available.

– After that, the applied ZirLiner is briefly dried and fired.

– The IPS e.max Ceram ZirLiner should have a layer thickness of approximately

0.1 mm after firing

Wax-up

The wax-up must be fabricated using wax that fires without leaving any residue. The cut-back technique is conducted as

follows:

– The stone die is isolated with a conventional plaster-wax separator

– Calipers are used to measure and record the thickness of the ZirCAD framework at various points.

– The ZirCAD framework onto which IPS e.max Ceram ZirLiner has been fired is weighed and the weight recorded. Once

the wax-up has been made, this data is used to determine the wax weight.

– Subsequently, the framework is secured in the correct position on the die. The margins are attached with wax first.

– A fully anatomic wax-up is created in the usual way and a silicone matrix is made.

– The waxed-up framework can be reduced at this stage. Alternatively, the framework can be pressed to full contour and

then reduced by grinding.

– If the wax-up is reduced, the incisal layer has to be trimmed selectively. A wax thickness of 0.7 mm must be observed to

avoid incomplete press results.

Sprueing

Always place the sprues in the direction of flow of the ceramic and at the thickest part of the wax up in order to achieve

unimpeded flow of the viscous ceramic material. The 100 g or 200 g investment ring base is selected depending on the

number of objects to be invested. Bridges must be pressed using the 200 g investment ring system. The following sprueing

guidelines must be observed:

Sprueing is carried out on the IPS e.max investment ring base. Sprues are attached in the direction of flow of the ceramic and always at the thickest part of the restorations

Preheating

After the stipulated setting time of the respective investment material (IPS PressVEST or IPS PressVEST Speed), the

investment ring is prepared for preheating as follows:

– Remove the ring gauge and ring base with a turning movement.

– Carefully push the investment ring out of the IPS Silicone Ring.

– Remove rough spots on the bottom surface of the investment ring with a plaster knife and check the 90° angle.

– Investment material residue must not enter the sprues. Blow into the sprues if necessary.

– If several investment rings are preheated together, mark them with the respective ingot shade.

In order to ensure smooth working procedures in the laboratory on a daily basis, impeccable functioning of the infrastructure and the

preheating furnaces is essential. This includes their maintenance, cleaning with a vacuum cleaner in a cool state as well as regular checks

of the temperature controls and heating elements, etc, by the manufacturer.

Place the investment ring towards the rear wall, tipped with the openingfacing down.

Do not preheat IPS e.max ZirPress ingots and Alox plunger.

Calibration

It is important to note that press furnaces must be calibrated on a regular basis. For information please see page 24.

Pressing

Before the preheating cycle for the investment ring has ended, the following preparations for pressing must

be carried out:

– Provide a cold IPS e.max Alox Plunger and a cold IPS e.max ZirPress ingot in the desired shade.

– After that, dip the cold IPS e.max Alox plunger into the opening of the IPS e.max Alox Plunger Separator

and keep ready for use.

– Select the press program for IPS e.max ZirPress.

Once the preheating cycle has been completed, remove the investment ring from the preheating furnace

and proceed as follows. Make sure that you take no more than 1 minute for these steps to prevent the

investment ring from cooling down too much.

– Insert the cold IPS e.max ZirPress ingot into the hot investment ring.

– Insert the ingot with the rounded, non-imprinted side into the investment ring. The imprinted side should

face upward to double-check the ingot shade.

– Place the powder-coated cold IPS e.max Alox plunger into the hot investment ring.

– Place the completed investment ring at the center of the hot press furnace using the investment tongs.

– Press START to start the selected program.

Insert the cold IPS e.max ZirPress ingot into the hot investment ring with the shade designation facing upward.

Divesting

After cooling to room temperature (approximately 60 minutes), the investment ring may show cracks.

These cracks developed (immediately around the Alox plunger) during cooling as a result of the different

CTEs of the various materials (Alox plunger, investment material, and pressed materials). They do not

compromise the press result.

Divest the investment ring as follows:

– Mark the length of the Alox plunger on the cooled investment ring.

– Separate the investment ring using a separating disk. This predetermined breaking point enables reliable

separation of the Alox plunger and the ceramic material.

– Break the investment ring at the predetermined breaking point using a plaster knife.

– Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure.

– Fine divestment is carried out with glass polishing beads at 2 bar (30 psi) pressure.

– Do not use Al2O3 for rough or fine divestment

– When divesting the object, blast from the direction indicated in the schematic below and observe the

appropriate distance in order not to damage the object margins.

– Any ceramic residue on the Alox plunger is removed with Al2O3 (type 100 microns).Mark the length of the Alox plunger

Separate the investment ring using a separating disk and break it at the predetermined breaking point

Rough divestment is carried out with glass polishing beads at 4 bar (60 psi) pressure until the restoration is visible.Fine divestment is conducted at 2 bar (30 psi) pressure.

43


After fine divestment, the reaction layer formed during the press procedure is removed using IPS e.max

Press Invex Liquid followed by blasting. The procedure is carried out as follows:

– Pour the Invex Liquid into a plastic cup.

– Immerse the pressed objects into the Invex Liquid and clean in an ultrasonic cleaner for at least

5 minutes and a maximum of 10 minutes. Make sure that the objects are completely covered with

Invex Liquid.

– Subsequently clean the object under running water and blow dry.

– Carefully remove the white reaction layer using Al2O3 Type 100 at 1–2 bar (15–30 psi) pressure.

– Make sure that the reaction layer is completely removed, both on the cavity side and on the outer side

of the object (repeat the procedure, if necessary).

– If the reaction layer is not entirely removed, bubbles may develop, which may lead to bonding

problems or even cracks in the layering ceramic.

– Replace the Invex Liquid after approximately 20 uses or after sedimentation of the liquid.

Remove the reaction layer with Invex and Al2O3 at 1–2 bar (15–30 psi) pressure.

Warnings

– The Invex Liquid contains < 1 % hydrofluoric acid.

– It is harmful when inhaled, swallowed, and when it comes into contact with the skin.

Furthermore, it is corrosive.

– Keep the container tightly sealed and store it in a well-ventilated place (acid cabinet).

– If the material comes into contact with the eyes, immediately rinse with copious amounts of water

and see a physician immediately.

– If the material comes into contact with the skin, immediately clean with soap and copious amounts

of water.

– Use suitable protective clothing, gloves, and goggles when working.

– In case of an accident or physical discomfort, see a physician immediately (bring the Invex label, if

possible).

Disposal

– Neutralize the Invex Liquid

– Neutralize the diluted solution by adding lime or baking soda and letting it react for 5 minutes.

– After the reaction time, pour the neutralized solution into the sink, flushing it with running water.

44

Finishing

It is of critical importance to use the correct grinding instruments for finishing and adjusting glass-

ceramics. If unsuitable grinding instruments are used chipping of the edges and local overheating may

occur (please see the corresponding recommendations from Ivoclar Vivadent).

The following procedure is recommended to finish IPS e.max ZirPress frameworks:

– Wet the area to be ground and use a fine diamond disk to cut the sprues. Try the restoration in on

the model.

– Prevent overheating of the ceramic material. Low speed and light pressure is recommended. Please

observe the corresponding instructions of the manufacturer.

– Smooth out the attachment points of the sprues.

– Do not 'post-separate' the bridge framework using separating disks, since this may result in undesired

predetermined breaking points, which will subsequently compromise the stability of the all-ceramic

restoration.

– Finish the restoration with diamonds to achieve a natural-looking shape and surface.

– Blast the framework with Al2O3 at 1 bar (15 psi) and clean it under running water or with steam prior

to staining and characterizing.

– Some blasting machines may require different pressure settings to accomplish this procedure.

Optional

Die fabrication with IPS Natural Die Material

The light-curing IPS Natural Die Material simulates the shade of the prepared tooth. A control die is fabricated using the

shade information provided by the dentist (shade determination). This control die represents the optimum basis for a

true-to-nature shade reproduction of the given oral situation.

– Coat the inner surfaces of the ceramic restorations with IPS Natural Die Material Separator and allow it to react for a

short time.

– Apply die IPS Natural Die Material in the corresponding shade to the inner surfaces of the restoration using the

IPS Condenser and adapt so that the entire inner surface is coated and filled.

– Completely fill the restoration cavity and insert an IPS Die Holder into the material and adapt excess material around the

holder. Make sure that the Die Material is well adapted to the restoration margins and that no gaps are present.

– Polymerize the IPS Natural Die Material die with a commercial polymerization light, e.g. Lumamat 100, for 60 seconds.

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

Use low rpms and light pressure to grind away sprue attachment points and achieve a natural-looking shape and surface.

– To achieve adequate heating of the individual restorations the heating rate should be lowered by 5–10 ºC (41–50 °F)

as well as the holding time should be extended by 30 seconds.



Staining, characterizing and glazing with IPS e.max Ceram

The most important staining and characterization steps are described below. Detailed information about the nano-

fluorapatite ceramic and its processing are contained in the IPS e.max Ceram Instructions for Use.

46

Stain and characterization firing

Before the stain and characterization firing cycle is conducted, the restoration must be free from dirt and oil. After

cleaning, the restoration must not be contaminated in any way. The procedure is conducted as follows:

– To promote wetting of the stains, IPS e.max Ceram Glaze and Stain Liquid (longlife) can be lightly painted onto the

surface.

– Mix the paste or powder with the IPS e.max Glaze and Stain Liquid (allround and longlife) until the desired

consistency is achieved.

– If stronger shades are desired, these are created by repeated staining rather than by applying shades too thickly.

– IPS e.max Ceram Shade Incisal is used to imitate the appearance of the incisal edge and the translucency in the incisal

third.

– Fissures and cusps are individually characterized with Essence materials.

Glaze firing

Glaze firing is carried out with Glaze powders or pastes. The following procedure is

recommended:

– Mix the required Glaze to the desired consistency with the IPS e.max Glaze and

Stain Liquids (allround and longlife).

– Evenly apply the glaze on the entire restoration.

– If a higher fluorescence is desired in the cervical region, fluorescent Glaze materials

(paste or powder) can be used in this area.

Conditioning of the ceramic surface in preparation for cementation is decisive for generating a sound bond between the

luting material and the all-ceramic restoration.

In the combination of IPS e.max ZirCAD and IPS e.max ZirPress, the conditioning measures must be conducted according

to the indications. The following points must be observed:

– High-strength zirconium oxide ceramics are generally not etched with hydrofluoric acid (IPS Ceramic Etching Gel), as it

does not produce an etching pattern.

– Zirconium oxide-supported restorations may be blasted at max. 1 bar (15 psi) pressure to clean the surfaces prior to

cementation.

– If ceramic materials have been pressed onto inlay-retained bridges, the glass-ceramic to which the other materials have

been pressed must be etched with hydrofluoric acid (IPS Ceramic Etching Gel) and silanated and seated according to

adhesive luting methods.

For the cementation of IPS e.max ZirPress restorations, you may choose between the tried-and-tested luting composites

and cements of the coordinated assortment from Ivoclar Vivadent.

Please observe the IPS Ceramic Etching Gel Instructions for Use.

– 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.


– 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.
