thanks to ideal processing characteristics,

The hybrid ceramic helps save you
both time and money in a range of steps.
The patient also benefits from shorter
treatment times, as well as from supe-
rior-quality results that offer properties
similar to natural dentition in terms of
look, feel and functionality.

For questions andmore information,
Dr. Rauscher can be reached at
milling mode and 132 posterior crowns in
fast-milling mode. Initial practice experi-
ence confirms this trend.
The fact that no firing is required at all

KIT (six stains including accessories) can
be used for shade characterization.
The stains are bonded to the restora-
tion as part of a polymerization process,
and surface sealing can be performed
using the chemical glaze material VITA
Enamic GLAZE.
Try-in was carried out for the inlay,
followed by adhesive bonding using
VITA Duo Cement. Final polishing was
performed for one minute in each case
using the VITAEnamic Polishing Set clin-
ical and silicon carbide polishing instru-
ments, and was followed by high-gloss
polishing using gray diamond burrs. The
final results blend in perfectly with the
remaining natural dentition (Fig. 17).
SUMMARY
VITA ENAMIC is a material that is
convincing—notonlybecauseofitsproper-
ties similar to thoseofnatural dentition, but
also because of its outstanding efficiency

impression data of the preparation,
antagonists and maximum intercuspa-
tion, digital models were created (Figs.
6-8). The software also generated buccal
bite registration (Figs. 9-10). Figure 11
shows the occlusal contacts. In the next
step, concrete planning of the new inlay
began with the definition of the prepara-
tion margin (Fig. 12). When determining
the modeling parameters, using the
"Minimal Thickness (Radial)" setting (Fig.
13) allowedmargins to be delicatelymilled
so that one of the special properties of
VITA Enamic could be used to full effect.
A software-generated model was then
suggested for the inlay (Fig. 14). Following
slight adjustment of the design, the block
was selected (Fig. 15) and the milling
preview displayed (Fig. 16). Fabrication
was performed using CERECMCXL.
The processing time for an inlay using
normal milling mode is just under eight
minutes; in fast-milling mode, it’s approxi-
mately four-and-a-half minutes. Tests
conducted by the manufacturer show that
a longer service life can be achieved: using
one set of milling tools, it was possible to
fabricate 148 posterior crowns in normal
