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.

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.
If desired, the screw channel of the hybrid abutment
19
can be sealed with a foam pellet.
Tip: The inner aspect of the crown can be isolated with glycerine gel.
