With the new IPS Empress Esthetic Line for
inlays, partial crowns, full crowns and
veneers, the product family has been further
enhanced. The result is an extremely homo-
geneous leucite glass-ceramic, which
features natural light scattering and offers a
balanced chameleon effect. Due to an
increased density and homogeneity of the
crystals, the restorations blend beautifully
into the natural surroundings. Moreover, the
flexural strength of the ingots has been
improved from 138 ± 12 MPa to 160 ± 8 MPa.
Objects fabricated using the lost-wax
technique feature a particularly high accuracy
of fit, as there is no sinter shrinkage.
IPS Empress Esthetic consists of
IPS Empress Esthetic Ingots ,
the coordinated
IPS Empress Esthetic Speed
investment material
and the IPS Empress Esthetic
Veneer layering materials.
The ingots are available in the popular
Staining Technique shades as well as two
new bright shades: E TC0 and E OC1. With
the layering materials, veneers and anterior
crowns exhibiting outstanding aesthetic
properties and accuracy of fit can be cost-
effectively fabricated by applying a combined
press/layering technique.
A tried-and-tested system
Aesthetics and longevity are important considerations for all-ceramics.
The IPS Empress press-ceramic system has proven itself for more than
15 years as regards both criteria. Twenty-five million placed restora-
tions are testimony to the durable true-to-nature effect, long-lasting
success and the high quality standard of IPS Empress. Clinical studies,
for example, show survival rates of 95% after 11 years.
