A sound concept is the key to success
The fully developed IPS Classic metal-ceramic that has clinically
proven itself for many years offers a high degree of individuality
and creativity. Controlled particle size distribution permits
excellent build-up and maintenance of shape of the ceramic
material even after several firing cycles.
Generally, IPS Classic is
suitable for use with
alloys with a CTE of
approx 13.8 to 15.2
x 10
-6
/K at 25–500°C.
Depending on the type
and the composition of
the alloy, the firing
temperature and the
cooling phase in
particular have to be
taken into con-
sideration. Alloys with a CTE in the lower range (e.g. approx
13.8–14.5 at 25–500°C) can be processed with standard
cooling.

Classification: Dental ceramics Type I / Class 1
Indication
Conventional multi-layer veneering ceramic for the most popular
dental alloys in the CTE range of 13.8 – 15.2 x 10
-6
/K
(25 – 500°C)
Contraindication
– If patients are known to be allergic to any of the ingredients,
the material should not be used
– Bruxism
– Veneering of titanium and zirconium oxide frameworks
– Any other use not listed in the indications
Important processing restrictions
– Exceeding or falling short of the stipulated veneering layer
thicknesses
– Failure to observe the layer thickness ratio between the
framework and layering ceramic
– Mixing with and processing in conjunction with other dental
ceramics
– Veneering of dental alloys not within the stipulated CTE range
– Failure to observe the necessary minimum connector and
framework thicknesses
– Use of IPS Shade, IPS Shade V and IPS Stains-P during the
layering procedure (e.g. between the dentin and incisal layer)
– Mixing of paste materials with materials in powder form
Side effects
If patients are known to be allergic to any of the components in
the materials, IPS Classic restorations should not be used.
Important information
Ceramic furnaces of other manufacturers often feature opening
mechanisms different from that of Ivoclar Vivadent furnaces.
Therefore, the firing conditions may also differ. Make sure that
these varying firing conditions are taken into account when
working with IPS Classic.
Warning
Finishing ceramic restorations results in grinding dust. Avoid
inhalation. Use suction equipment or protective masks.
