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 true-to-

nature fluorescence are the results of

these development efforts.
