System
IPS e.max is an innovative all-ceramic system which covers the entire all-ceramic indication range – from thin veneers to 14-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 glass­ceramics for smaller restorations and high-strength zirconium oxide for large-span bridges.
The requirements and aims of every case differ. IPS e.max meets these requirements, because due to the system components, you obtain exactly what you need.
– In the field of the Press technology, the highly esthetic IPS e.max Press lithium
disilicate glass-ceramic is available and with IPS e.max ZirPress a fluor apaptite glass-ceramic ingot for the quick and efficient press-on technique on
zirconium oxide.
– For the CAD/CAM technology, depending on the case requirements, the innovative
lithium disilicate block IPS e.max CAD is used or the high-strength zirconium oxide IPS e.max ZirCAD.
– The nano-fluorapatite layering ceramic IPS e.max Ceram, which is used to
characterize and/or veneer all IPS e.max components – glass or oxide ceramics –, completes the IPS e.max System.

Product Information
Description
IPS e.max® CAD Abutment Solutions are CAD/CAM-fabricated, implant-supported hybrid restorations for single teeth. These hybrid restorations are individually fabricated of lithium disilicate glass-ceramics (LS2) and cemented onto a titanium base (Ti base).
Two different approaches are available: – IPS e.max CAD hybrid abutment and separate IPS e.max CAD crown – IPS e.max CAD hybrid abutment crown
Both solutions show outstanding function, efficiency and esthetics. The durable bond to the Ti base is achieved by means of the self-curing Multilink® Hybrid Abutment luting composite.
Hybrid abutment
The hybrid abutment is an individually milled LS emergence profile and esthetic properties of this abutment can be ideally adjusted to the clinical situation.
Given the lifelike appearance of LS2 glass-ceramics, the esthetic possibilities are virtually limitless, particularly in the anterior region. Due to the individual characterization, a lifelike appearance is achieved near the root and the transition area to the crown. With the preparation margin of the crown located on the gingival level, the geometry of the hybrid abutments allows for an easy integration of the restoration. Excess cementation material is therefore easily removed.
The milled and crystallized LS2 ceramic structure is extraorally luted to a Ti base with Multilink Hybrid Abutment, then screwed into place in the oral cavity and finally pro­vided with a permanent IPS e.max CAD crown. Given the convenient fabrication of the hybrid abutment, the process is time-saving and flexible.

Hybrid abutment crowns are characterized by combining abutment and monolithic crown in one piece. This is an efficient two-in-one solution made of lithium disilicate (LS

LS2 glass-ceramics provide for strength, durability and efficiency, particularly in the posterior region. Moreover, the material offers well-known esthetic properties, allowing restorations to be simply characterized with IPS e.max Ceram stains.
The monolithically milled hybrid abutment crown is reliably and extraorally luted to the Ti base by means of Multilink Hyrid Abutment. Then, the restoration is screwed onto the implant – in one piece. Subsequently, the screw access channel is sealed with a composite material (e.g. Tetric EvoCeram®). If required, the screw can be accessed at any time, which affords the dental team clinical flexibility.
IPS e.max CAD hybrid abutment crowns are a new, economically attractive alternative to conventional implant-supported restorations, particularly for the posterior region, where strength, durability and convenient clinical handling matter.

Material
IPS e.max CAD
IPS e.max CAD is a lithium disilicate glass-ceramic block for the CAD/ CAM technology. 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 MPa. After the IPS e.max CAD blocks are milled, the restora­tion is crystallized in an Ivoclar Vivadent ceramic furnace (e.g. Programat easy-to-conduct crystallization process neither causes any major shrinkage, nor are any complicated infiltration processes required. The crystallization process leads to a change in the microstructure in the IPS e.max CAD material, during which lithium disilicate crystals grow. 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.

Shade – tooth shade and abutment shade
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. With IPS e.max CAD Abutment Solutions, you can imitate not only the clinical crown of a natural tooth, but also a part of the root. This allows you to achieve highly esthetic implant-supported restorations which retain their lifelike appearance also in the case of gingiva recession.
For IPS e.max CAD hybrid abutment and the separate crown, the desired tooth shade results from – the shade of the IPS e.max CAD hybrid abutment (IPS e.max CAD MO ceramic structure, Multilink Hybrid Abutment) – the shade of the luting material for intraoral cementation of the crown on the IPS e.max CAD hybrid abutment
(e.g. SpeedCEM)
− the shade of the IPS e.max CAD LT crown.

CAD/CAM processing
As densification of about 0.2% occurs in IPS e.max CAD during crystallization, this factor has been taken into account in the respective software of the tested CAD/CAM system. Consequently, the milled IPS e.max CAD restorations demonstrate a high accuracy 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.
13
Finishing
It is of critical importance to use the correct grinding instruments for finishing and adjusting the IPS e.max CAD ceramic structure. 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").
Basic notes regarding the finishing of IPS e.max CAD
– 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 speed and light pressure to prevent delamination and chipping at the
margins in particular. Overheating of the glass-ceramic must be avoided. – During finishing, make sure that the minimum layer thicknesses are observed. – Cut the ceramic structure from the block using a diamond separating disc. Slightly scratch the attachment area at the
incisal side of the abutment and separate the attachment point from the basal.
Checking the fit of the ceramic structure on the Ti base
– Carefully place the ceramic structure on the Ti base and check the fit. Observe the position of the rotation lock.

Finishing
Important! – Do not finish the shoulder of the ceramic structure to prevent negatively affecting the Ti base. – Finish the emergence profile if required taking the fit to the gingiva and the minimum thickness (0.5mm) into
account.
Finishing the outer surface of the ceramic structure (hybrid abutment)
– Smooth out the attachment point to the block with fine diamond grinding instruments taking the shape of the
emergence profile and the crown margin into account.
– Do not perform any individual shape adjustments, as this will negatively affect the fit of the crown on the hybrid
abutment. Note regarding the crown: If there are any inaccuracies of fit to the hybrid abutment, adjust the crown by grinding.
Finishing the outer surface of the ceramic structure (hybrid abutment crown)
– Smooth out the attachment point to the block with fine diamond grinding instruments taking the shape of the
emergence profile and the proximal contacts into account.
– Surface-grind the entire occlusal surface with a fine diamond to smooth out the surface structure created by the
CAD/CAM procedure. – Check the proximal and occlusal contacts. – Design surface textures.
– Clean the ceramic structures with ultrasound in a water bath or blast with the steam jet before further processing. – Make sure to thoroughly 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 ceramic structures with Al
or glass polishing beads!

Optional: Clinical try-in
A clinical try-in to check the accuracy of fit can be conducted prior to further processing. Clinical try-in may also take place at a later stage, i.e. with the crystallized, tooth-coloured IPS e.max CAD ceramic structure.
Provisional securing of the ceramic structure on the Ti base
To facilitate the intraoral handling, the components are temporarily attached to one another with silicone material, e.g. Virtual Extra Light Body Fast Set.
The following procedure should be observed in the temporary attachment of the components: – Clean the untreated Ti base and the ceramic structure with steam and subsequently dry with blown air. – Place the ceramic structure on the Ti base (which is screwed on the model analog) and mark the relative position of
the components with a waterproof pen. This step makes it easier to attain the correct position when the parts are
temporarily assembled. – Seal the screw channel with a foam pellet. – Insert the Virtual cartridge in the dispenser and remove the protective cap. – Screw on the mixing tip and attach the Oral Tip to the mixing tip. – Apply Virtual Extra Light Body Fast Set to the Ti base and directly into the ceramic structure. – Introduce the Ti base into the ceramic structure. The alignment of the two component must be checked
(rotation lock/marking). – Hold the components firmly in the correct position for 2:30 minutes until Virtual Extra Light Body Fast Set has set. – Carefully remove any excess that has been displaced with a suitable instrument, e.g. a scalpel.

Clinical try-in
Hybrid abutment and dedicated crown
Important note: Any intraoral inspection of the occlusion/articulation and necessary grinding adjustments may only be
carried out if the components have been attached to one another with Virtual Extra Light Body Fast Set. Virtual has a cushioning effect during the try-in procedure, in particular, if any grinding adjustments have to be made. Therefore, it prevents chipping in the transition area between the hybrid abutment and the crown.
The following procedure should be observed during the clinical try-in: – The prepared hybrid abutment (provisionally secured in place) and the clean corresponding crown are laid out. – Remove the provisional restoration. – Screw the hybrid abutment in manually with the dedicated screw. – Check the geometry of the hybrid abutment (e.g. fit gingival anaemia) in relation to the gingival margin. – If desired, the screw channel on the hybrid abutment can be sealed with a foam pellet. – Tip: Isolate the inner aspect of the crown with glycerine gel, e.g. Try-in paste, Liquid Strip – Place the crown on the hybrid abutment intraorally to check and adjust the proximal contacts, if necessary.
Note: No occlusal functional inspection must be performed at this stage.
– For the functional inspection, the crown has to be secured on the hybrid abutment with Virtual Extra Light Body Fast Set.
Try-in paste must not be used for this purpose, as this material is not sufficiently resistant to compressive force. – Insert the Virtual cartridge in the dispenser and remove the protective cap. – Screw on the mixing tip and attach the Oral Tip to the mixing tip. – Apply Virtual Extra Light Body Fast Set to the inner aspect of the crown. – Press the crown onto the hybrid abutment using the fingers until it has reached the final position. Hold the crown in the
final position until the Virtual material has set. – Remove excess Virtual material. – Check the occlusion/articulation and make adjustments with suitable grinding instruments, if necessary (see separate
IPS e.max recommended grinding instruments for ceramics – use in the dental practice). – Carefully remove the crown from the hybrid abutment and the hybrid abutment from the implant (including the Ti base). – Rinse the implant site e.g. with Cervitec Liquid (antibacterial mouth wash with chlorhexidine) to clean and disinfect it. – Place the temporary restoration.
Optional – Clinical Try-In
The hybrid abutment is manually screwed in place with the dedicated screw. The geometry of the hybrid abutment (e.g. fit, gingival anaemia) is checked in relation to the gingival margin.

Preparing for Combination firing (Crystallization and Stain/Glaze firing in one step)
– Clean the ceramic structure with the steam jet to remove any contaminations and grease residue. Any contamination
after cleaning must be prevented. – Use the IPS e.max CAD Crystallization Pin XS for the crystallization of the ceramic structure. – Fill the interface of the ceramic structure with either IPS Object Fix Putty or Flow auxiliary firing paste. Immediately
reseal the IPS Object Fix Putty/Flow syringe after extruding the material. – Press the IPS e.max CAD Crystallization Pin XS only slightly into the IPS Object Fix Putty/Flow. Important: Do not
press the pin in too deep to make sure that it does not touch the walls. This may lead to cracks in the ceramic
structure.
– Smooth out displaced auxiliary firing paste using a plastic spatula so that the pin is securely in place. – Prevent contamination of the outer surface / occlusal surface of the ceramic structure. – Clean off any possible contamination with a brush dampened with water and dry.

– The glazing material must neither reach the bonding surface to the Ti base nor the screw channel, as this may
compromise the accuracy of fit. Check the interface before firing and carefully remove any contamination.
– On the abutment, do not apply any materials to the bonding surface to the crown, as this might compromise the fit
of the crown.
– Apply IPS e.max CAD Crystall./Glaze Paste evenly on the areas to be glazed using a small brush. Avoid to apply too thick
a glaze layer. Avoid "pooling", especially on the occlusal surface of the abutment crown. – Too thin a glaze layer may lead to an unsatisfactory gloss. – Apply characterizations with IPS e.max CAD Crystall./Shades and/or IPS e.max CAD Crystall./Stains. For that purpose,
extrude the Shades and Stains from the syringe and mix. If necessary, slightly thin them 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. More intensive shades are
achieved by several staining procedures and repeated firing, not by applying thicker layers. – To imitate the incisal area and translucency of the hybrid abutment crown in the incisal and occlusal third, IPS e.max

Cementation with Multilink® Hybrid Abutment
The following instructions must be observed in the cementation procedure: – The cleaned and conditioned components (ceramic structure, Ti base) are laid out ready for cementation. – The subsequent cementation procedure must be carried out quickly and without interruption. The working
time of Multilink Hybrid Abutment is approximately 2 min at 23 °C (± 1 °C) or 73 °F (± 1.8 °F).
– As a general rule, a new mixing tip is attached to the Multilink Hybrid Abutment syringe prior to each use. – Apply a thin layer of Multilink Hybrid Abutment directly from the mixing syringe to the bonding surface of the Ti base
and the bonding surface of the ceramic structure.
– The mixing tip is left on the Multilink Hybrid Abutment syringe until the next use. The remaining cement polymerizes in
the tip and functions as a seal. – Place the ceramic structure on the Ti base in such a way that the position markings are aligned. – Press the parts lightly and evenly together and check the correct relative position of the components (transition Ti base/
ceramic structure). – Subsequently, press the parts tightly together for 5 s. – Carefully remove excess in the screw channel, e.g. with a Microbrush or brush, using rotary movements.
Important:
Important: Excess must not be removed before curing has started, i.e. 2-3 minutes after mixing. For the
purpose, a suitable dental lab instrument (e.g. Le Cron) is used. The components are held in place with light pressure in the process.
– Glycerine gel is applied (e.g. Liquid Strip) on the cementation joint to prevent the formation of an inhibition layer. The
glycerine gel must be applied cautiously to avoid blending it with or displacing the composite. Make sure to leave the gel
on the cementation joint until polymerization is complete. – Next, the luting composite is completely auto-polymerized within 7 min. – Important: Do not move the components until Multilink Hybrid Abutment has completely cured. They can be
held immobile with e.g. diamond-coated tweezers.
– After the completion of auto-polymerization, rinse off the glycerine gel with water. – Make sure to cautiously polish the cementation joint with rubber polishers at a low speed (< 5,000 rpm) to
avoid overheating. – Remove any cement residue left in the screw channel with suitable rotating instruments. – Clean the restoration with ultrasound in a water bath or with the steam jet.

Sterilization
The hybrid abutments or hybrid abutment crowns must be sterilized prior to insertion. Furthermore, the locally applicable legal regulations and the hygiene standards applicable for a dental practice must be observed.
Steam sterilization can be performed with the 3 x fractionated pre-vacuum with the following parameters: Sterilization time 3 min; steam temperature 132 °C/270 °F; resulting in a half-cycle exposure time of 1.5 min. The abutment is for immediate use. No storage after sterilization!
The responsibility for the sterility of the hybrid abutment or hybrid abutment crown lies with the user. It must be ensured that only suitable devices, materials and product-specifically validated methods are used to perform sterilization. The equipment and devices must be properly maintained and serviced at regular intervals. The fabricator (dental technician) of the IPS e.max CAD Abutment Solution must inform the dentist of the need to sterilize the abutment before inserting it in the patient’s mouth!
Intraoral preparation
Please observe the following procedure to prepare for the permanent cementation of the implant-supported restoration: – Remove the temporary restoration. – Clean the implant site. – Check the periimplant tissue (emergence profile).

Seating the hybrid abutment and crown
Preparing/conditioning the hybrid abutment with dedicated crown
Conditioning of the ceramic surface, i.e. the bonding surface, in preparation for cementation is critical for generating a sound bond between the cementation material and the all-ceramic material.
The following procedure must be observed in the preparation of the ceramic structure for cementation on the Ti base: – Do not blast IPS e.max CAD hybrid abutment or IPS e.max CAD crown with Al – Ideally, the clinical try-in is conducted before etching to prevent contamination of the bonding surface. – Thoroughly clean the hybrid abutment and crown with water and subsequently blow dry. – Etch the bonding surface with 5% hydrofluoric acid gel (IPS Ceramic Etching Gel) for 20 s. The etching gel must not
come into contact with the emergence profile or the outer side of the crown. Important: No intraoral application of
the IPS Ceramic Etching Gel. – Subsequently, thoroughly rinse the bonding surface under running water and dry it with air that is free or water and oil. – If an adhesive or self-adhesive cementation protocol is used, apply Monobond Plus to the clean bonding surface and
allow it to react for 60 s. After this reaction time, disperse any residue with air that is free of water and oil.

General Information
Frequently Asked Questions
In addition to the desired tooth shade, why should the root shade also be defined/ determined upon shade determination?
IPS e.max CAD Abuttment Solutions allow you to fabricate restora­tions with a lifelike appearance both in the visible area and the area below the gingiva (root). By defining the root shade, a highly esthetic outcome can be achieved especially in the case of receding gingiva.
Is it possible to fabricate an abutment or an abutment crown with IPS e.max CAD (LS
No! For this indication, IPS e.max CAD needs the support provided by the Ti base. In addition, the Ti base allows an optimum (industrially fabricated) fit to the implant to be achieved.
Which Ti bases can be used for the fabrication of IPS e.max CAD Abutment Solutions?
Only Ti bases of authorized CAD/CAM systems may be used. More information about the CAD/CAM cooperation systems is available on the Internet from www.ivoclarvivadent.com.
) without using a Ti base?
2
Do IPS e.max CAD ceramic structures have to be glazed in all cases?
No. High gloss can also be achieved by a corresponding polishing procedure. The polishing technique (before crystallization) is pre­ferably used for the emergence profile of the hybrid abutment. For the hybrid abutment crown, the application of glaze is recommended.
Is it possible to use an IPS e.max CAD hybrid abutment as an abutment for a bridge restoration?
No. Only single-tooth restorations may be fabricated.
Can different CAM units be used for milling the IPS e.max CAD ceramic structure (abutment) and the dedicated IPS e.max CAD crown?
If different CAM units are used, inaccuracies of fit may occur in unfavourable cases. Therefore, both IPS e.max CAD objects (abutment, crown) should be ideally milled in the same CAM unit.
Is it permissible to modify the selected Ti base?
The Ti base must not be adjusted by grinding, as this would compro­mise the fit of the IPS e.max CAD ceramic structure. The instructions of the manufacturer regarding the preparation for permanent cementation must be observed.
Is a hybrid abutment crown indicated in the anterior region?
This indication depends on the position and inclination of the implant. If the opening of the screw channel is located on the oral surface, a hybrid abutment crown may be fabricated in the anterior region.
May a hybrid abutment crown be cut-back and subsequently supplemented with IPS e.max Ceram layering materials.?
No. For implant-supported restorations, it is recommended to fabricate monolithic restorations (without veneer). In this way, chipping of the layering ceramic is prevented.
Can a clinical try-in be conducted with the IPS e.max CAD Abutment Solutions? How are the ceramic structures prepared for this?
Yes. Clinical try-in may be performed either before or after crystalli­zation of the IPS e.max CAD ceramic structures. The Ti base and IPS e.max CAD ceramic structure are temporarily joined in the laboratory by means of a silicone material, e.g. Virtual Extra Light Body Fast Set. This facilitates the intraoral handling during clinical try-in with the patient.
What must be observed for the clinical try-in of a crown on a hybrid abutment?
To check the occlusion/articulation and to make possible adjustments, the crown must be temporarily secured on the hybrid abutment with a silicone material, e.g. Virtual Extra Light Body Fast Set. The silicone material acts as a buffer and prevents chipping in the marginal area of the crown. Try-in pastes or Vaseline must not be used for functional checks.
60
Can a glaze spray be used for glazing IPS e.max CAD ceramic structures (e.g. IPS e.max CAD Crystall./Glaze Spray)?
We do not recommend using the Glaze Spray for the indications hybrid abutment or hybrid abutment crown, as there is a risk that the bonding surface to the Ti base or the scew channel are conta­mination with glaze.
What material is used to permanently cement the IPS e.max CAD ceramic structures to the Ti base?
Only Multilink Hybrid Abutment is to be used for permanent cemen­tation. This ensures a high-quality bond. Given the high opacity of the luting composite, complete optical masking of the Ti base is achieved and thus an excellent esthetic appearance ensured.
How is the Ti base prepared for the permanent cementation with Multilink Hybrid Abutment?
Provided it has been approved by the manufacturer, carefully blast the bonding area with Al
at low pressure until an even mat
2O3
surface has been achieved. After cleaning, the area is conditioned with Monobond Plus.
General Information – Frequently Asked Questions
How is the screw channel of a hybrid abutment crown sealed after seating?
The screw channel is extraorally conditioned (etching, silanating). After the restoration has been intraorally screwed down on the implant, the screw channel is sealed with a restorative composite.

Crystallization and Firing 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 CS, Programat P300, P500,
or P700).
– If you 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 calibrations may be required. Observe the instructions of the man-
ufacturer.
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 the Pins, i.e. with-
out 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
