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 sometimes
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.
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 trueto-
nature fluorescence are the results of
these development efforts.
