requirements of this material. An abso-
lute true running polisher, adjusted grain
sizes and individual geometries are used
to support the user in achieving esthetic
results. Occlusal surfaces, cusps, fissures
and contact points of the restoration
should be polished in a very gentle way
so that there is a reduced risk of micro
cracks occurring. What is also beneficial
apart —from ease-of-use and the high
removal rate — is that no polishing paste
is required and the instruments can be
sterilized. Surfaces with a high gloss are
obtained (Fig. 11).
Immediately after polishing, try-in of
the crown in the patient’s mouth was
possible (Fig. 12), and the crown was
cemented using the adhesive technique
directly afterwards (Fig. 13). Figure 14
shows the good result.

CHARACTERIZED POSTERIOR CROWN
It was planned to restore the tooth in
region 26 with a crown made of VITA
Enamic that was characterized using the
staining technique (Fig. 15). The treat-
ment process followed the usual work-
flow. Figure 16 shows the tooth prepa-
ration, while figures 17 and 18 display
screenshots of the virtual design and
figure 19 is an image taken during try-in
of the crown. After having checked the
fit of the restoration and the occlusal
contacts, finishing was done using
the staining technique with the VITA
Enamic STAINS KIT (Figs. 20-22).
The VITA Enamic stains are suited for
occlusal and cervical characterization.
Six shades — white, corn, brown, khaki,
blue and black — are available. The
accessory includes liquid, mixing plate,
