Material
Press­ceramic
IPS e.max Press are lithium disili-
cate glass-ceramic (LS
2
) ingots for
the press technology. The industrial
production process creates abso-
lutely homogeneous ingots in dif-
ferent translucency levels. For IPS e.max Press Abutment Solutions,
ingots from the exisitng range of products are used.
The ingots feature a strength of 400 MPa and are thus the pressed
ceramic ingots with the highest strength. They are pressed in Ivoclar
Vivadent press furnaces to produce objects with outstanding accuracy
of fit. The pressed, tooth-coloured, highly esthetic restorations are
completed with IPS e.max Ceram.
Uses
Indications
– Hybrid abutments for anterior and posterior single-tooth
restorations
– Hybrid abutment crowns for anterior and posterior restorations
Contraindications
– Use of Ti bases which do not fulfil the geometry requirements.
– Failure to observe the requirements stipulated by the implant
manufacturer for using the selected implant type (diameter and
length of the implant must be approved for the respective position
in the jaw by the implant manufacturer).
– Bruxism
– Failure to observe the permissible maximum and minimum ceramic
wall thicknesses.
– All uses not stated as indications are contraindicated.
Important­processing­restrictions
Failure to observe the following restrictions may compromise the
results achieved with IPS e.max Press:
– If hybrid abutment crowns are fabricated, the opening of the
screw channel must not be located in the area of contact points
and areas with masticatory function. If this is not possible, a
hybrid abutment with a separate crown would be preferred.
– No extension units; only single-tooth restorations
– Layering with a veneering ceramic other than IPS e.max Ceram
– Pressing of two or more IPS e.max Press ingots in one investment
ring
– Pressing of IPS e.max Press in the IPS Investment System 300 g
– Use of a luting composite other than Multilink
® Implant to lute
IPS e.max Press to the Ti base
– Temporary cementation of the crown on the hybrid abutment.
– Failure to observe the manufacturer's instructions regarding the
processing of the Ti base.
