Usage
Indications
– Veneers
– Inlays
– Onlays
– Partial crowns
– Crowns for anterior and posterior restorations
– Implant superstructures for single-tooth restorations (anterior and
posterior region)
Contraindications
– Full veneers on molar crowns
– Very deep subgingival preparations
– Patients with severely reduced residual dentition
– Bruxism
– Any other use not listed in the indications
Important processing restrictions
Failure to observe the following restrictions may compromise the
results achieved with IPS e.max CAD:
– The frameworks must not fall below the required minimum
thickness.
– Do not mill the blocks with non-compatible CAD/CAM systems.
– Crystallization must not be conducted in a ceramic furnace that
has not a vacuum function.
– Crystallization must not be conducted in a ceramic furnace that
has not been calibrated.
– Crystallization must not be conducted in a ceramic furnace that
has not been approved and/or recommended.
– Crystallization must not be conducted in a high-temperature
furnace (e.g. Sintramat).
– Do not mix IPS e.max CAD Crystall./Glaze, Shades and Stains with
other dental ceramics (e.g. IPS e.max Ceram Glaze, Stains and
Essence).
Side effects
If the patient is known to be allergic to any of the components
of IPS e.max CAD, the material must not be used to fabricate
restorations.

Warning
– Do not inhale ceramic dust during finishing — use exhaust air
discharge and mouth protection.
– IPS Ceramic Etching Gel contains hydrofluoric acid. Contact with
skin, eyes and clothing must be prevented at all costs, since the
material is extremely toxic and corrosive. The etching gel is
intended for extraoral use only and must not be applied intra-
orally (inside the mouth).
