The requirements for functionality and
aesthetic appearance of ceramic restorations
are continuously rising. To meet these requi-
rements manufacturers are faced with the
challenge of developing materials that satisfy
the needs of experienced ceramists, by
offering them a multitude of design
possibilities, and less experienced users by
enabling them to have a successful start in
the field of porcelain-fused-to-metal
restorations. In order to give a high end
ceramic the ease of handling that customers
expect, the range of indications of IPS d.SIGN
was given top priority during the
development phase.
With a well designed basic assortment and
the various additional assortments of
IPS d.SIGN, beginners and specialists alike
will have all the materials they need to
restore lost tooth structure in a true-to-
nature, highly aesthetic fashion. IPS d.SIGN is
a material suitable for basic types of restora-
tions, as well as restorations having
sophisticated morphological structures. In
this way, all the demands placed on the
material prior to its development have been
fully met.
With IPS d.SIGN, highly aesthetic restorations
that are virtually undetectable among their
natural counterparts may be fabricated by
easy, efficient layering of the material.
Moreover, expert ceramists are provided with
a comprehensive range of additional
materials.
The shades of IPS d.SIGN are based on the
Chromascop and A–D shade guides. Shade
tabs fired from the actual material are
supplied with each assortment.
Comprehensive Treatment
System
Ivoclar Vivadent provides you with a
comprehensive treatment system that
consists of the following components:
– Alloys
– Veneering ceramic
– Cementation system
This system was developed with the objective
that all of the materials should be coordina-
ted with each other so that optimum results
are achieved. The IPS d.SIGN fluorapatite
leucite ceramic is an innovative ceramic
material that offers new ways of processing
and application. These properties of
IPS d.SIGN are based on its new material
specifications. What does that means in
practical work?
Fluorapatite leucite glass-
ceramic
IPS d.SIGN fluorapatite leucite glass-ceramic
has been developed taking nature as the
standard, with the most important properties
of natural teeth serving as models. The main
inorganic component of a natural tooth are
apatite crystals, in which hydroxyl and some-
times carbonate groups are embedded. In
addition to this composition, IPS d.SIGN
fluorapatite glass-ceramics also contains
fluoride ions that provide the material with a
very high chemical resistance. Moreover, the
above mentioned compositions results in
IPS d.SIGN demonstrating exceptional optical
properties, which is yet another distinct
advantage of this new type of glass-ceramic
material. Increased brightness and brilliance,
clearly enhanced stability of shade, and true-
to-nature fluorescence are the results of
these development efforts.
