Using of non-metal ceramics, like building material for making
prosthetic restaurations, makes fixed requierements in front of
non-metal system itself.The power of building material needs to accord
with indications, chemical stability must exists and, overall, high
accords for making prosthetic restaurations with esthetic
characteristics. Basic on idea that the future of non-metal systems will
be in using PRESS and CAD-CAM technology was developed a new system
under tittle IPS e.max (Ivoclar Vivadent, Schaan, Liechtenstein). It
embraces the most esthetic and high-stifness materials for PRESS and
CAD-CAM technology. In a production of IPS e.max Press ingots we use a
new technology of prcessing. The ingots don’t more produce via powder
phase, like in a case with IPS Empress 2 ingots, then with the molding
of raw material. Like result, we have a material which doesn’t have
pore. New non-metal ceramic system, like is IPS e.max, shows many
potential fields of the using. This material can be used for making
inleys, onleys, veneers, three-unit frontal and lateral bridges and in a
case of adhesive restaurations in lateral segment. The advantages of
this procedure are minimal invasivity, gingival health, easy procedure
and low cost. It is leucit-glass ceramic which has good stiffness,
optical quality and new pressing procedure for shaping materials and
those characteristics have opened a way to success, and new pressing
procedure for shaping of materials represents important contribution to
the development of non-metal ceramic systems.
