System –

all you need

IPS e.max is an innovative all-ceramic system which covers the entire all-ceramic indication range – from thin veneers to 10-unit bridges.

IPS e.max delivers high-strength and highly esthetic materials for the Press and the CAD/CAM technologies. The system consists of innovative lithium disilicate glass-ceramics used mainly for singletooth restorations and high-strength zirconium oxide for large-span bridges.

Every patient situation presents its own requirements and objectives. IPS e.max meets these requirements. Due to the system components you obtain exactly what you need. – The components of the Press technology include the highly esthetic IPS e.max Press lithium disilicate

glass-ceramic ingots and the IPS e.max ZirPress ﬂuorapatite glass-ceramic ingots for the fast and efﬁcient press-on-zirconia technique.

– Depending on the case requirements, two types of materials are available for CAD/CAM techniques:

the innovative IPS e.max CAD lithium disilicate blocks and the high-strength zirconium oxide IPS e.max ZirCAD.

– The nano-ﬂuorapatite layering ceramic IPS e.max Ceram, which is used to characterize/veneer all

IPS e.max components – glass or oxide ceramics – completes the IPS e.max System.

IPS e.max CAD

The shades and translucency levels of the IPS e.max CAD blocks are based on the overarching IPS e.max shade system. The system has a ﬂexible design and can be used in conjunction with the A-D, Chromascop as well as Bleach BL shade guides.

The shades of the Press ingots and CAD/CAM blocks offered in the IPS e.max System are all coordinated with each other. They are available in different degrees of opacity and/or translucency. The selection of the translucency level is based on the clinical requirements (shade of the prepared tooth, desired tooth shade) presented by the patient, as well as the desired processing technique (layering, cut-back, staining technique). The more opaque HO (only IPS e.max Press) and MO blocks are predominantly suitable for the layering technique, while the more translucent LT and HT blocks are used for the cut-back and also the staining technique.

Product Information

Material

IPS e.max CAD is a lithium disilicate glass-ceramic block for the CAD/CAM technique. It is fabricated using an innovative process which provides an impressive homogeneity of the material. The block can be processed very easily in a CAD/CAM unit in this crystalline intermediate stage. The typical and striking colour of IPS e.max CAD ranges from whitish to blue and bluish-grey. This shade is a result of the composition and the microstructure of the glass-ceramic. The strength of the material in this processable intermediate phase is 130-150 MPa. After the IPS e.max CAD blocks are milled, the restoration is crystallized in an Ivoclar Vivadent ceramic furnace (e.g. Programat®P300, P500, P700). Unlike with some other CAD/CAM ceramics, the approximately 20-31-minute, easyto-conduct crystallization process neither causes any major shrinkage, nor are any complicated inﬁltration processes required. The crystallization process at 840-850°C (1544-1562°F) results in a transformation of the microstructure, during which lithium disilicate crystals grow in a controlled manner. The densiﬁcation of 0.2% is accounted for in the CAD software and taken into account upon milling. The ﬁnal physical properties, such as the strength of 360 MPa and the corresponding optical properties, are achieved through the transformation of the microstructure.

Block Concept

IPS e.max CAD is available in three levels of translucency (HT, LT, MO) and two sizes (I12, C14). From a processing point of view, basically all restorations can be fabricated from any block. For reasons of esthetics, however, the following processing techniques and indications are recommended for the individual blocks (translucency levels):

IPS e.max CAD HT (High Translucency)

The HT Blocks are available in 16 A-D and 4 Bleach BL shades and 2 sizes (I 12, C 14). Given their translucency, they are ideally suitable for the fabrication of small restorations (e.g. inlays, onlays) by means of the staining technique, but they can also be used for the cut-back technique. Restorations made of HT blocks exhibit a true-to-nature chameleon effect and exceptional adaption to the remaining tooth structure. The stain and characterization ﬁring, as well as glaze ﬁring may be conducted with either IPS e.max CAD Crystall./Shades and Stains, Glaze, or IPS e.max Ceram Shades, Essences and Glaze.

IPS e.max CAD LT (Low Translucency)

The LT Blocks are available in 16 A-D and 4 Bleach BL shades and 2 sizes (I 12, C 14). Given their translucency, they are suitable for the cut-back and also the staining technique. Restorations made of LT blocks exhibit lifelike brightness value and chroma. This prevents the incorporated restorations from graying. The cut-back is supplemented with IPS e.max Ceram Incisal and/or Impulse and characterized using IPS e.max Ceram Essence and Shade.

IPS e.max CAD MO (Medium Opacity)

The MO Blocks are available in 5 group shades (MO 0 - MO 4) in one size (C 14). Given their opacity, they are ideally suitable for the fabrication of frameworks on vital or slightly discoloured preparations. The anatomical shape is individually layered using ISP e.max Ceram. Finally, the Stain/Glaze ﬁring with IPS e.max Ceram is conducted.

Shade Determination — Tooth Shade, Shade of the Prepared Tooth

Optimum integration in the oral cavity of the patient is the prerequisite for a true-to-nature all-ceramic restoration. To achieve this, the following guidelines and notes must be observed by both the dentist and the laboratory. The overall esthetic result of an all-ceramic restoration is influenced by the following factors:

• Shade of the preparation (natural preparation, core build-up, abutment, implant)

• Shade of the restoration (framework shade, veneer, characterization)

• Shade of the cementation material

The optical effect of the preparation shade must not be underestimated during the fabrication of highly esthetic restorations. For that reason, the shade of the preparation should be determined together with the desired tooth shade in order to select the suitable block. Especially with severely discoloured preparations or non-tooth-shaded build-ups, this is of utmost importance. Only if the dentist determines the shade of the preparation and its subsequent transmission to the laboratory may the desired esthetic result be achieved.

Shade determination of the natural tooth

After tooth cleaning, the tooth shade of the non-prepared tooth and/or the adjacent teeth is determined with the help of a shade guide. Individual characteristics have to be considered when determining the tooth shade. If a crown preparation is planned, for example, the cervical shade should also be determined. In order to achieve the best possible true-to-nature results, shade determination should be carried out in daylight. Furthermore, the patient should not wear clothes of intense colours and/or lipstick.

Die shade selection

In order to facilitate the reproduction of the desired tooth shade, the shade of the preparation is determined with the help of the IPS Natural Die Material shade guide. This enables the technician to fabricate a model die similar to the preparation of the patient, on the basis of which the correct shade and brightness values of the all-ceramic restorations may be selected.

Example of the preparation shade effect

Overview of the Clinical Working Steps, Fabrication Process

Which block should be used?

The suitable block is selected on the basis of the following criteria:

1. Desired tooth shade

2. Preparation shade or abutment shade

3. Type of restoration

4. Restoration thickness and/or preparation depth

5. Processing technique (staining, cut-back or layering technique)

6. Cementation material

– A preparation depth of at least 1.0 mm and an

isthmus width of at least 1.0 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 onlay surfaces. For onlays 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. – Do not prepare slice-cuts or feather edges. – Provide at least 1.0 mm of reduction in the cusp areas.

Overview of the Clinical Working Steps, Fabrication Process

– Static and dynamic antagonist contacts must be taken

into consideration.

– The preparation margins must not be located on

centric antagonist contacts.

– Provide at least 1.5 mm of reduction in the cusp

areas.

– Prepare a circular shoulder with rounded inner edges

or a deep chamfer. Width of the shoulder/chamfer should be at least 1.0 mm.

– Reduce the anatomical shape and observe the

stipulated minimum thickness. Prepare a circular

shoulder with rounded inner edges or a deep

chamfer. Width of the shoulder/chamfer at least

1.0 mm. – Reduce the incisal crown third by approx. 1.5 mm. – Reduce the buccal or lingual area by approx. 1.5 mm. – For conventional and/or self-adhesive cementation,

the preparation must demonstrate retentive surfaces

Model and Tooth Preparation

Fabricate a working model with removable segments as usual. The directions of the manufacturers of the different CAD/CAM systems regarding the plaster to be used must be observed.

Important for die preparation:

– Check the radius of the incisal/occlusal edge on the prepared die (maxilla and mandible). – The prepared incisal edge should be at least as thick as the diameter of the bur used in the cavity

during the CAD/CAM process.

– If the incisal edge of the prepared die is thinner than the diameter of the bur, the incisal edge has to

be blocked out accordingly.

– Also observe the information provided by the manufacturer of the CAD/CAM system regarding the die

geometry.

Layer thicknesses

The restoration design is key to the success of durable all-ceramic restorations. The more attention is given to the design, the better the ﬁnal results and the clinical success will turn out to be. The following basic guidelines have to be observed:

– IPS e.max CAD is the high-strength component of your restoration and must, therefore, always make up at

least 50% of the total layer thickness of the restoration.

– In large preparations and for veneered or partially veneered restorations, the excess available space must be

compensated by the corresponding dimensions of the high-strength IPS e.max CAD component and not by the IPS e.max Ceram layering material.

– The design of the restoration generated by the software has to be individually adjusted, if necessary, in accordance with

the clinical situation using the design tools.

– The areas that support and reinforce the shape and cusps of the restoration are constructed with the integrated design

tools of the different types of software used.

– In partially veneered restorations, the transition between the layering material and IPS e.max CAD must not be located

in the area of the functional contact points.

The following minimum thicknesses have to be observed to match the tooth shade of the shade guide and to fulﬁl the requirements given from the preparation guidelines:

CAD/CAM processing

As densiﬁcation of about 0.2% takes place in IPS e.max CAD during the crystallization process. This factor has been taken into account in the software. Consequently, the milled IPS e.max CAD restorations demonstrate precision of ﬁt after crystallization. The fabrication steps are described in the directions for use and user manuals of the different CAD/CAM systems. The instructions of the manufacturers must be followed:

Staining technique

In the staining technique, the milled full-contour restorations are completed by applying stains and glaze materials. Individualized characterizations and glaze can be applied either before or after Crystallization firing. Coordinated materials are available for the different procedures. In this way, the use of translucent IPS e.max CAD blocks permit the fabrication of very esthetic restorations on only slightly or non-discoloured preparations with minimum effort.

Finishing

It is of critical importance to use the correct grinding instruments for ﬁnishing and adjusting IPS e.max CAD. If unsuitable grinding instruments are used, chipping of the edges and local overheating may occur (please observe the Ivoclar Vivadent Flow Chart ”Recommended grinding tools for PS e.max glass-ceramics”.

Observe the following procedure for ﬁnishing IPS e.max CAD restorations: – Carry out adjustments by grinding of IPS e.max CAD restorations while they are still in their pre-crystallized (blue) state,

if possible.

– Only use suitable grinding instruments, low rpms and light pressure to prevent delamination and chipping at the edges

in particular. – Overheating of the glass-ceramic must be avoided. – The restorations are tried in on the dies and carefully ﬁnished. – Check proximal and occlusal contact points. – Surface-grind the entire occlusal surface with a ﬁne diamond to smooth out the surface structure created by the

CAD/CAM procedure. – Make sure that the minimum thicknesses are maintained even after the minor adjustments. – Design surface textures. – Always clean the restoration with ultrasound in a water bath or blast with the steam jet before crystallization. – Make sure to thoroughly clean the restoration before further processing and to remove any residue of the milling

additive of the CAD/CAM milling unit. Residue of the milling additive remaining on the surface may result in bonding

problems and discolouration. – Do not blast the restorations with Al2O3or glass polishing beads.

Crystallization and Stain/Glaze Firing

Basically, fully anatomically milled restorations made of IPS e.max CAD can be completed in three different ways.

Staining Technique

Option A:

Crystallization and Glaze ﬁring with IPS e.max CAD Crystall./Glaze paste

Characterization of the non-crystallized,

blue restoration permits quick comple-

tion of the restoration with the

subsequent combination firing

(Crystallization/Glaze HT/LT).

Option B:

Crystallization and Stain/Glaze ﬁring

with IPS e.max CAD Crystall./Glaze spray

Characterization of the non-crystallized,

blue restoration permits quick comple-

tion of the restoration with the

subsequent combination firing

(Crystallization/Glaze HT/LT).

Option C:

Crystallization and separate Stain/Glaze

ﬁring with IPS e.max Ceram Shades,

Essences and Glaze

Characterization of the tooth-coloured

restoration after crystallization.

Option A:

Crystallization and Glaze ﬁring in one step with IPS e.max CAD Crystall./Glaze paste

In this processing technique, crystallization and Glaze ﬁring are performed in one step. Characterizations are applied using IPS e.max CAD Crystall./Shades and Stains.

Preparation for Crystallization and Glaze firing

Depending on the type of restoration, they have to be placed on an IPS e.max CAD Crystallization Pin before the Stains and Glaze are applied. Smaller restorations (veneers, inlays, onlays) do not need to be entirely supported. Either IPS Object Fix Putty or Flow are recommended to secure the restoration on the pin. The Putty demonstrates a denser consistency and thus higher stability. Given its lower viscosity, Flow is suitable for smaller restorations.

To apply Glaze, Shades and Stains, secure the restoration – with an OptraStick, – with diamond tweezers, or – directly on the die Note: the restoration must be placed on a Crystallization pin with IPS Object Fix Putty or Flow before firing.

Observe the following procedure for partial crowns and crowns: – Select the largest possible IPS e.max CAD Crystallization Pin (S, M, L) that best “fills” the inside of the

restoration, but does not come into contact with the circular crown walls.

– Fill the inside of the restoration with IPS Object Fix Putty or Flow up to the restoration margin.

Immediately reseal the IPS Object Fix Putty/Flow syringe after extruding the material. Once removed from the aluminium bag, the syringe is ideally stored in a resealable plastic bag or a container with a humid atmosphere.

– Press the selected IPS e.max CAD Crystallization Pin deeply into the IPS Object Fix Putty or Flow

material so that it is adequately secured.

– Smooth out displaced auxiliary firing paste using a plastic spatula so that the pin is securely in place

and the restoration margins are optimally supported.

– Prevent contamination of the outer restoration surface. Clean off contamination with a brush

dampened with water and dry.

Please observe the following procedure: – Hold the restoration by the firing pin and apply IPS e.max CAD Crystall./Glaze Paste evenly on the entire restoration

using a brush.

– Hold inlays, onlays or veneers with an OptraStick or diamond tweezers when applying IPS e.max CAD Crystall./Glaze

Paste, or directly apply paste while the restoration is seated on the die. – If a slight thinning is desired, the glaze may also be mixed with a little IPS e.max CAD Crystall./Glaze Liquid. – Avoid applying too thick a glaze layer. Avoid pooling, especially on the occlusal surface. – Too thin a glaze layer may lead to an unsatisfactory gloss. – If characterizations are desired, the restoration can be individualized using IPS e.max CAD Crystall./Shades and Stains

before Crystallization firing. – Extrude Shades and Stains from the syringe and mix thoroughly. – The Shades and Stains may be slightly thinned using IPS e.max CAD Crystall./Glaze Liquid. However, the consistency

should still remain pasty. – Apply mixed Shades and Stains directly into the unfired glaze layer using a fine brush.

Crystallization and Stain/Glaze ﬁring in one step with IPS e.max CAD Crystall./Glaze Spray

IPS e.max CAD Crystall./Glaze Spray is used instead of IPS e.max CAD Crystall./Glaze Paste. The spray should only be used if IPS Object Fix auxiliary ﬁring paste is adapted up to the margins.

Preparation for Crystallization and Glaze firing

If IPS e.max CAD Crystall./Glaze Spray is used, all the restorations, irrespective of their geometry, have to be placed on the IPS e.max CAD Crystallization Pin with the help of IPS Object Fix Putty or Flow.

Exactly adapt IPS Object Fix Putty or Flow to the

restoration margin so that the Glaze Spray is

prevented from reaching the inner aspects.

Procedure: – Secure the restoration on a suitable IPS e.max CAD Crystallization Pin as described in Option A. – Make sure that the auxiliary firing paste (IPS Object Fix Putty or Flow) is flush with the restoration

margin. If veneers, inlays, and onlays are glazed with Glaze Spray, they also have to be enclosed in firing paste exactly to the restoration margin.

Combination firing (Crystallization and Stain/Glaze firing in one step)

– Before starting the characterization and glazing procedure, make sure the outside of the restoration is

free of auxiliary firing paste.

– If characterizations are desired, the restoration can be individualized using IPS e.max CAD

Crystall./Shades and IPS e.max CAD Crystall./Stains before Crystallization firing. – Extrude ready-to-use Shades and Stains from the syringe and mix thoroughly. – The Shades and Stains may be slightly thinned using IPS e.max CAD Crystall./Glaze Liquid. However,

the consistency should still remain pasty. – Apply mixed Shades and Stains directly on the blue restoration using a brush.

Apply mixed Shades and Stains directly on the blue restoration

Please observe the following procedure for the application of the IPS e.max CAD Crystall./Glaze Spray: – Hold the restoration by the IPS e.max CAD Crystallization Pin. Do not spray the restoration while it is placed on the

IPS e.max CAD Crystallization Tray, as it would also be coated with glaze. – Shake the spray can well immediately before use until the mixing ball in the container is moving freely

(approximately 20 seconds). If the spray is not sufﬁciently shaken, mainly the propellant is discharged

with a spraying burst. This, in turn, results in insufﬁcient application of the glazing powder. – Observe a distance of approx. 10 cm between the nozzle and the surface to be sprayed. – Hold the spray can as upright as possible during spraying. – Spray the restoration from all sides with short bursts while simultaneously rotating the restoration so that

an even, covering layer is created. Shake the spray can again between individual bursts. – Spray the restoration a second time from all sides with short bursts while simultaneously rotating the

restoration so that an even, covering layer is created. Shake the spray can again between individual

bursts. – Wait brieﬂy until the glaze layer is dry and has assumed a whitish colour. – Areas that do not show an even layer have to be sprayed again. – Place the restoration in the center of the IPS e.max CAD Crystallization Tray. – Conduct the Combination ﬁring (Crystallization/Glaze LT/HT) using the stipulated parameters.

The following paragraphs will explain the most important veneering steps. For further information on the nano-ﬂuorapatite layering ceramic and its processing, please refer to the IPS e.max Ceram Instructions for Use.

Firing tray and pins

Use a honey-combed ﬁring tray (e.g. IPS

UniTray) and the corresponding support pins to ﬁre the restorations (do not use IPS e.max CAD Crystallization Tray or IPS e.max CAD Crystallization Pins). Round the top edges of the support pin to prevent the restoration from sticking to the pin. Another method of reducing this risk is to cover the pins with platinum foil or a small amount of IPS Object Fix Putty or Flow. Regularly clean the support pins. Do not use contaminated pins.

Wash ﬁring (foundation)

The restoration must be free of dirt and grease before the wash ﬁring is done. Any contamination after cleaning must be prevented. Wash ﬁring is carried out with IPS e.max Ceram Incisal and Impulse materials or Shades and Essences.

Cut-Back Technique

Option A: Powder

Conduct the wash ﬁring with the required IPS e.max Ceram Incisal and/or Impulse materials. Use the IPS e.max Ceram Build-Up Liquids allround or soft to mix the materials. If a more plastic consistency is desired, IPS e.max Ceram Glaze and Stain Liquid allround or longlife can be used. Apply the wash in a thin coat on the entire framework.

Option B: Glaze, Shades and Essence

To enhance the in-depth chroma effect or for individualized internal characterizations, the wash firing can be conducted with Glaze, Shades and Essence. Mix the paste or powder with the IPS e.max Ceram Glaze and Stain Liquids allround or longlife to the desired consistency. Apply the wash in a thin coat on the entire framework.

Layering materials must not be applied on unﬁred wash layers (powders and pastes), since this will result in a delamination of the layering ceramic. The wash (foundation) must be ﬁred before the actual layering procedure is started.

Incisal ﬁring

With the Incisal ﬁring, the anatomical shape is completed and the individual esthetic appearance achieved. The layering procedure is conducted with IPS e.max Ceram Transpa and Impulse materials. To achieve the desired consistency, the IPS e.max Ceram Build-Up Liquid allround and soft can be used. If a different consistency is desired, the liquids can also be mixed in any ratio.

Due to the thin material layer and the thus resulting limited shape change during ﬁring, the cut-back technique also allows to complete the restoration with one ﬁring cycle. If a second Incisal ﬁring is required, however, it can be conducted using the same ﬁring parameters.

Finishing and preparing for the 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.

– If gold and/or silver dust was used to visualize the surface texture, the

restoration has to be thoroughly cleaned with steam. Make sure to remove all gold or silver dust in order to avoid any discolouration.

Finish the restoration with diamonds and give it a true-to-nature shape and surface structure

Stain and Glaze ﬁring

Stain ﬁring is conducted with IPS e.max Ceram Essence and IPS e.max Ceram Shades, while Glaze ﬁring is carried out with IPS e.max Ceram Glaze powder or paste. Depending on the situation, the Stain and Glaze ﬁrings may be conducted together or separately one after the other. The ﬁring parameters are identical. In order to achieve an even gloss during Glaze ﬁring of cut-back restorations veneered with IPS e.max Ceram, two different procedures are possible:

Layering Technique

In the layering technique, the IPS e.max Ceram layering materials are fired onto the framework made of IPS e.max CAD MO. This enables very individualized design possibilities. The opacity of IPS e.max CAD MO permits the design of highly esthetic restorations even on discoloured dies as well as metal core build-ups or Ti abutments.

Finishing and Preparation for Crystallization

It is of critical importance to use the correct grinding instruments for ﬁnishing and adjusting IPS e.max CAD. If unsuitable grinding instruments are used, chipping of the edges and local overheating may occur (please observe the corresponding Ivoclar Vivadent Flow Chart ”Recommended grinding tools for IPS e.max glass-ceramics”.

Observe the following procedure for ﬁnishing IPS e.max CAD restorations: – Carry out adjustments by grinding of milled IPS e.max CAD restorations while they are still in their pre-crystallized (blue)

state whenever possible.

– Only use suitable grinding instruments, low rpms and light pressure to prevent delamination and chipping at the edges

in particular. – Overheating of the glass-ceramic must be avoided. – The frameworks are tried in on the dies and carefully ﬁnished. – Make sure that the minimum thicknesses are maintained even after the minor adjustments. – Always clean the framework with ultrasound in a water bath or blast with the steam jet before crystallization. – Do not blast the framework with Al2O3or glass polishing beads.

Crystallization

The following points should be observed for the crystallization: – Crystallization should be carried out in an Ivoclar Vivadent ceramic furnace (e.g. Programat

P300, P500 or P700).

– Use only IPS Object Fix Putty or Flow as an auxiliary ﬁring paste to ideally place the restoration

on the ﬁring tray.

– The cavity of the restoration must be entirely ﬁlled with IPS Object Putty or Flow and extended so that

there is a reservoir.

– IPS e.max CAD restorations must neither be placed on metal ﬁring pins nor a honey-combed tray for

crystallization.

– Use only the IPS e.max CAD Crystallization Tray, since it stores the heat necessary for slow and above all tension-free

cooling of the restoration.

– Always allow the restoration to cool to room temperature after crystallization before further processing.

Seating and Follow-Up Care

Possibilities for Cementation

Possibilities for esthetic cementation are decisive for the harmonious shade effect of an all-ceramic restoration. Depending of the indication, IPS e.max CAD restorations can be seated using either adhesive, self-adhesive or conventional cementation.

– For the adhesive cementation of IPS e.max CAD restorations, Variolink®II, Variolink®Veneer or Multilink®Automix are

the ideal cements. – For the self-adhesive cementation of IPS e.max CAD restorations, SpeedCEM is available. – We recommend using Vivaglass®CEM, the glass ionomer cement, for the conventional cementation of IPS e.max CAD.

Definition

• Adhesive cementation

With adhesive cementation, the bond is also created by static friction, but primarily by the chemical and/or micro-

mechanical bond between the luting material and the restoration, as well as between the luting material and the

preparation. Given the chemical and/or micromechanical bond, retentive preparation is not required. Irrespective of the

cementation material, special adhesive systems are used on the preparation to generate the micromechanical bond with

the dentin and/or enamel.

Adhesive cementation results in enhanced ”(overall) strength” of the seated all-ceramic restoration.

• Self-adhesive cementation

The cementation material features self-etching properties to the tooth, but not to the restoration, which is why no addi-

tional special conditioning of the tooth surface is necessary. Hence, the adhesion of the restoration is partially achieved

by a micromechanical and/or chemical bond. In order to achieve sufﬁcient bonding strength values, retentive preparation

is recommended.

• Conventional cementation

In the conventional cementation technique, the bond is achieved nearly exclusively through mechanical friction between

the cementation material and the restoration as well as between the cementation material and the preparation. To

achieve the necessary static friction, retentive preparation with a preparation angle of approximately 4-6° is required.

Conventional cementation does not result in enhanced ”(overall) strength” of the all-ceramic restoration.

Preparing for Cementation

Conditioning of the restoration and preparation depends on the cementation method used. The following paragraphs describe the basic working steps to prepare for cementation.

a. Conditioning of the restoration

Conditioning of the ceramic surface in preparation for cementation is decisive for generating a sound bond between the cementation material and the all-ceramic restoration. The following steps must be observed: – Do not blast IPS e.max CAD with Al2O3or glass polishing beads before incorporation. – Ideally, conduct the clinical try-in before etching in order not to contaminate the etched surface. – Thoroughly clean the restoration with water and blow dry. – Condition the restoration:

– Generally etch the bonding surface with 5% hydrofluoric acid gel (IPS Ceramic Etching Gel). – For adhesive or self-adhesive cementation, silanize the bonding surface of the restoration using Monobond Plus.

o not blast IPS e.max CAD restorations

Etch for 20 s with IPS Ceramic Etching Gel Let Monobond Plus react for 60 seconds

and blow dry

* Conventional cementation is done without conditioning The range of products on offer may vary from country to country

Please observe the corresponding Instructions for Use.

a. Conditioning of the preparation

Thoroughly clean the preparation once the temporary has been removed. Before it is conditioned, the restoration is tried in and the occlusion and articulation checked. If adjustments are required, the restoration may be polished extraorally in these areas before final incorporation.

Condition the preparation in accordance with the selected cementation material.

Care notes

Same as natural teeth, high-quality IPS e.max CAD restorations require regular professional care. This is beneficial for both the health of the gingiva and teeth, as well as the overall appearance. The pumice-free Proxyt pink polishing paste is used to care for the surfaces without causing any wear. The low RDA value = 7 (Relative Dentin Abrasion) is a reliable confirmation to use a cleaning paste that is only a little abrasive. Scientific investigations and long-term clinical experience have proved the gentle effect compared to other pastes.

Frequently Asked Questions

Why is it important to determine the shade of the preparation?

Depending on the translucency level of the block used, the shade of the preparation inﬂuences the seated allceramic restoration. Therefore, knowing the shade of the preparation is imperative. A corresponding tooth-coloured die is then fabricated with the help of IPS Natural Die Material. It is used to achieve an optimum match of the restoration shade to the given clinical situation.

When are IPS e.max CAD HT blocks used?

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 exhibit a true-to-nature chameleon effect and the exceptional adaption to the remaining tooth structure. When used for larger restorations (e.g. crowns), the brightness level of translucent blocks may decrease. In such cases, a block with a lower translucency (IPS e.max CAD LT) is required.

When are IPS e.max CAD LT blocks used?

Which type of plaster should be used to fabricate the models?

The instructions for the manufacturer of the CAD/CAM system in use should be observed in the fabrication of the models. The following basic rule applies: Depending on the CAD/CAM system and equipment, special plasters may have to be used for the fabrication of models and dies to ensure the quality of the scan. If a special scanning plaster is unavailable, models and dies can be fabricated with high-strength stone, which is sprayed with IPS Contrast Spray Labside immediately before the scanning procedure.

What kind of preparation requirements must the die demonstrate in order to produce accurately ﬁtting restorations?

The traditional preparation guidelines for allceramic resotrations apply to IPS e.max CAD. The thickness of the incisal edge of prepared anterior teeth (upper and lower) requires special attention. The prepared incisal edge should be at least as thick as the diameter of the bur used in the cavity. The corresponding instructions of the manufacturer regarding the dimensions of the grinding instruments must be observed during preparation.

Given their high brightness value compared to the HT blocks, LT blocks are ideally suitable for the fabrication of larger restorations (e.g. anterior and posterior crowns). Restorations made of IPS e.max CAD LT exhibit a lifelike brightness value and chroma. This prevents the incorporated restorations from graying.

Is IPS e.max CAD LT also suitable for the fabrication of frameworks for subsequent veneering?

The shading and translucency of the IPS e.max CAD LT material is designed for restorations fabricated in the staining and cut-back technique. If frameworks are made of IPS e.max CAD LT and subsequently fully veneered with IPS e.max Ceram (Dentin and Incisal materials), the shade and brightness values are slightly mismatched and the tooth shade might differ from the shade guide.

Can an incisal edge which has become too thin during preparation be adjusted prior to scanning to avoid complicating the try-in procedure after machining?

In cases such as these, we recommend blocking out the incisal edge of the prepared die until the thickness matches that of the bur. These areas will be ﬁlled with luting cement when the restoration is seated.

How can the accuracy of ﬁt of IPS e.max CAD restorations be adjusted?

If the accuracy of ﬁt on the die is to be adjusted, this can be achieved by changing the parameters in the corresponding CAD software. Additionally, there is the possibility to change the dimensions of the occlusal and proximal contacts

When should manual adjustments with grinding instruments be done?

All grinding adjustments of milled IPS e.max CAD restorations should be made in the pre-crystallized (blue) state. It is important to note that the framework in its pre-crystallized state should be ground only with suitable grinding instruments, low rpms and light pressure to prevent delamination and chipping, particularly at the margins.

Do IPS e.max CAD restorations require occlusal adjustment after the CAD/CAM process?

Yes. Surface-grind the outer surface, particularly functional areas with antagonist contact, with a ﬁne diamond to smooth out the surface structure created by the CAD/CAM process.

Can machined IPS e.max CAD restorations in the pre-crystallized (blue) state be completely ﬁnished and then crystallized and veneered?

Milled IPS e.max CAD restorations can be tried in on the die and all areas fully ﬁnished in the precrystallized (blue) state. Thin margins only after crystallization (silicone polishers), since margins that are too thin tend to round during crystallization.

Why does the auxiliary ﬁring paste IPS Object Fix Putty or Flow have to be used during the crystallization process?

In order to prevent distortion of the IPS e.max CAD restoration during crystallization, IPS Object Fix Putty or Flow are used. They support the restoration in an optimum manner and thus ensure exact accuracy of ﬁt after crystallization. Smaller restorations may be placed directly on the IPS e.max CAD Crystallization Pin with a small amount of IPS Object Fix Flow.

Can ﬁring pastes other than IPS Object Fix Putty or Flow be used in the crystallization process?

IPS Object Fix Putty and Flow has been specially developed for the crystallization of IPS e.max CAD restorations. The expansion behaviour has been optimally coordinated with IPS e.max CAD. In other words, the consistency before and after the crystallization allows the paste to be easily applied and cleanly removed. Given their composition, pastes of other manufacturers may cause damage to IPS e.max CAD. Furthermore, easy removal may not always be possible.

How are contaminations with IPS Object Fix Putty or Flow on the outer surface of the restorations best removed before crystallization?

Do IPS e.max CAD restorations shrink during crystallization?

No. During the crystallization process, the microstructure becomes transformed and a densiﬁcation of 0.2 % takes place. The milling software takes the densiﬁcation factor into account. Therefore, the milled IPS e.max CAD restorations demonstrate precision of ﬁt after crystallization. No further manual adjustments are necessary.

A short-hair brush or cotton swab dampened with water can be used for cleaning. It must be made sure that any residue has been removed before Shades, Stains or Glaze are applied in order to prevent the residue from being burned in.

How can premature drying of the IPS Object Fix Putty or Flow in the syringe be prevented?

What must be considered after the ﬁring of IPS e.max CAD?

In order to avoid a premature loss of moisture of the ﬁring pastes, remove the syringe from the aluminium bag only directly before initial use. Close the syringe immediately after usage. If the syringe is not used for a longer period of time, it can be stored in a resealable plastic bag together with a moist paper tissue.

Can other ﬁring trays, e.g. honey-combed trays, be used for the crystallization of IPS e.max CAD?

No other ﬁring trays should be used. The IPS e.max CAD Crystallization Tray contained in the assortment stores the heat necessary for slow and above all tension-free cooling of the glass-ceramic. Other ﬁring trays, e.g. honey-combed tray, cannot store the heat and therefore cool down too quickly.

Can furnaces other than the ones from Ivoclar Vivadent be used to crystallize IPS e.max CAD restorations?

The crystallization of IPS e.max CAD is specially coordinated with the Ivoclar Vivadent ceramic furnaces (e.g. Programat P300, P500 or P700). If you would like to use other, untested ceramic furnaces, please consult Ivoclar Vivadent about their compatibility with IPS e.max CAD. It is important to note that not every ceramic furnace can be used for crystallization. Ceramic furnaces that, for instance, do not feature controlled longterm cooling mode or vacuum cannot be used for this purpose.

In order to prevent tensions within the ceramic, remove the restoration from the furnace only after the ﬁring cycles have been completed (wait for the acoustic signal of the ceramic furnace). Allow the objects to cool to room temperature in a place protected from draft and do not touch them with metal tongs during that time. Do not blast or quench the objects.

Which materials should be used if additional shade adjustments are necessary after Combination ﬁring (Crystallization and Glaze ﬁring in one step)?

Since the characterizations have already been carried out using IPS e.max CAD Crystall./Shades and Stains for the Combination ﬁring, IPS e.max CAD Crystall./Shades and Stains have to be used again for any corrective ﬁring.

Can IPS e.max CAD Crystall./ Shades, Stains, Glaze and IPS e.max Ceram Shades, Essences, Glaze be used with one another?

No. Since the IPS e.max CAD Crystall. and the IPS e.max Ceram materials have to be ﬁred in a different manner, the materials cannot be mixed or applied at the same time.

Can IPS Empress Universal Shades, Stains and Glaze be used for IPS e.max CAD?

IPS Empress Universal Shades, Stains and Glaze were specially developed for and coordinated with the IPS Empress System and are therefore not suitable for IPS e.max products.

Can the quality of crystallization of IPS e.max CAD restorations be checked?

Optical inspection by means of the enclosed materials shade guide can be conducted. If the shade and opacity of the restoration match the material shade guide, crystallization was successful. The shade comparison must always be conducted on a neutral-coloured background and with incident light, rather than transmitted light. If the shade and opacity of the restoration deviate from that of the materials shade guide, e.g. too translucent, the restoration must be milled again. Crystallization cannot be repeated.

Can IPS e.max Ceram Margin materials be used with IPS e.max CAD?

IPS e.max Ceram Margin materials must not be used on glass-ceramics (IPS e.max Press and CAD), since the reduction for the shoulder would weaken the restoration.

Can IPS e.max CAD frameworks be blasted with Al2O3or glass polishing beads before they are veneered or after their completion (on the cavity side)?

IPS e.max CAD restorations must never be blasted with Al2O3or polishing beads, as this would damage the ceramic surface and reduce the outstanding physical properties.

How must the internal (bonding) surface of the IPS e.max CAD restorations be conditioned before cementation?

The internal (bonding) surfaces of IPS e.max CAD restorations must always be etched with hydroﬂuoric acid etching gel (IPS Ceramic Etching Gel) for 20 seconds, whether they are cemented with adhesive, self-adhesive, or con-ventional methods. The resulting retentive pattern enables an enhanced bond both with adhesives and selfadhesives as well as conventional bonding agents. After etching, the glass-ceramics are silanized using Monobond Plus when adhesive and selfadhesive cementation is used. With conventional cementation, silanizing is not necessary.

Can IPS e.max CAD restorations also be conventionally cemented?

IPS e.max CAD restorations can be cemented adhesively, self-adhesively or conventionally. If the restoration is to be conventionally cemented, however, an appropriately retentive preparation design must be observed (preparation angle of 4°-6°). If this is not possible, adhesive luting is preferred, e.g. Variolink

II and Multilink

Automix. It is not advisable to use classical phosphate cements, as they would negatively inﬂuence the light transmission of the all-ceramic and therefore compromise the esthetic appearance of allceramic restorations.

Table on Block Selection

The blocks are selected on the basis of the desired tooth shade (Bleach BL or A-D), the determined die shade (ND 1-ND 9), and/or abutment shade, as well as the desired processing technique. The following procedure results in the selection of the appropriate block:

1. Select the column with the desired tooth shade.

2. Select the line with the shade of the preparation.

3. Select the adequate block in accordance with the desired processing technique (staining, cut-back, or layering technique) in the intersection field.

4. If a certain combination is not possible (e.g. HT block on a dark preparation), select a block with a lower translucency.

– The recommendations for the block selection correlate with the indications as well as the preparation guide-

lines and minimum layer thicknesses.

– In case of shade deviations, adjust the restoration shade by means of characterization with Shades and/or

Stains or Essence. – If (highly) translucent blocks are used, the layer thickness and die shade must be carefully observed. – With thicker layers, a block with lower translucency must be selected to prevent a loss in brightness

(graying).

Crystallization Parameters

The following points should be observed for ceramic furnaces, used for the crystallization of IPS e.max CAD:

– Crystallization should be carried out in an Ivoclar Vivadent ceramic furnace (e.g. Programat P300, P500, or P700). – If you would like to use other, untested ceramic furnaces, please consult Ivoclar Vivadent about their compatibility with

IPS e.max CAD.

– Basically, the following applies:

Ceramic furnaces without – function for controlled (long-term) cooling – vacuum function

cannot be used. – Before the ﬁrst crystallization and every six months after that, the ceramic furnace must be calibrated. – Depending on the mode of operation, more frequent calibration should be required. Follow the instructions for the

manufacturer.

The following aspects should be observed for conducting the crystallization: – Use only IPS Object Fix Putty or Flow as an auxiliary ﬁring paste to place the restoration directly on the IPS e.max CAD

Crystallization Tray. – IPS e.max CAD restorations must not be directly placed on the IPS e.max CAD Crystallization Tray and Pins, e.g. without

auxiliary ﬁring paste, for crystallization. – Use only the IPS e.max CAD Crystallization Tray and the corresponding Pins, since they store the heat necessary for slow

and above all tension-free cooling of the glass-ceramic. – Always conduct the crystallization under vacuum. – Remove IPS e.max CAD objects from the furnace after completion of the ﬁring cycle (wait for the acoustic signal of the

furnace). – Allow the objects to cool to room temperature in a place protected from draft. – Do not touch the hot objects with metal tongs. – Do not blast or quench the objects.

Firing parameters

– Use a honey-combed tray and the corresponding pins for firing. – Ceramic pins must not be used, since they may fuse to the restoration. – The processing temperatures must be observed. An increase in the firing temperature results in severe vitrification

between the framework and the veneering ceramic, which may lead to cracks later. An decrease in the firing

temperature causes the ceramic to be underfired and very brittle, which may lead to delamination. – The parameters stipulated in the Instructions for Use are coordinated with Ivoclar Vivadent furnaces (tolerance range

+/- 10 °C). – If a non-Ivoclar Vivadent furnace is used, temperature corrections may be necessary. – Remove IPS e.max CAD objects from the furnace after completion of the firing cycle (wait for the acoustic signal of the

furnace). – Allow the objects to cool to room temperature in a place protected from draft. – Do not touch the hot objects with metal tongs. – Do not blast or quench the objects.

– The ﬁring parameters listed represent standard values and apply to the Ivoclar Vivadent furnaces P200,

P300, P500, P700. For Ivoclar furnaces of an older generation, e.g. P20, P80, P90, P95, P100, PX1 and EP600 Combi, these temperatures are also valid as standard values. However, depending on the age of the heat-

ing mufﬂe, the values may deviate by approximately ± 10 °C. – 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.
