Product Information
IPS
Material
IPS e.max Ceram is a low-fusing
nano-fluorapatite glass-ceramic
which permits the veneering and
characterization of restorations
fabricated using either the press
technology and/or the CAD/CAM
technology. This glass-ceramic,
which contains nano-fluorapatite
crystals, demonstrates a crystal structure similar to that of vital
teeth. The optical properties are controlled by the nano-
fluorapatite crystals in the size range of 100–300 nm and micro-
fluorapatite crystals with a length of 1–2 µm. The individual
IPS e.max Ceram materials contain different concentrations of the
apatite crystals, which then enable a unique and adjustable
combination of translucency, brightness and opalescence,
depending on the type of layering material. The IPS e.max ZirLiners
are yet another innovation of this new material concept. They
enable an exceptionally good bond with the zirconium oxide frame-
work and demonstrate high light transmitting capability coupled
with high fluorescence. They thus make the white and not very
translucent zirconium oxide frameworks look as if they have been
shaded and permit the adjustment of the basic zirconium oxide
shade of the framework to the shade of the IPS e.max Press and
IPS e.max CAD glass-ceramics. In this way, the achieved layering
concept permits the fabrication of highly esthetic restorations that
demonstrate optimum stability of shape both on shaded/translucent
glass-ceramic frameworks and on less translucent zirconium oxide
frameworks. The uniform material composition and, consequently,
homogeneous clinical properties, irrespective of the framework
material used, underlines the comprehensive IPS e.max restorative
concept.
IPS e.max Ceram is based on the tried-and-tested shade concept of
other Ivoclar Vivadent veneering materials. In this way, a continuous
concept covering composites, metal-ceramics and all-ceramics has
been achieved. The easy application makes the time-consuming
re-familiarization with the individual veneering materials a thing of
the past.
