when it comes to using cerec every
single day, I have realized that it is not
just being excited about CEREC. It’s
about using the CAD/CAM technology
in every instance possible; that is, it
becomes exciting to find ways to apply it
to everyday dentistry. Every time a new
product or technique emerges on the
market, I practice with it before I use it.
Of course, I develop my skills with the
guidance and input frommy fellow online
Mentors at cerecdoctors.com.
Oneof thenewrestorativemillingblocks
is Vita Enamic (Figs. 1-2), developed by
Dr. Russell Giordano from Boston Univer-
sity. It tookmore than10years tocreate the
porcelain scaffolding interspersed
with resin in its spaces. It was
worth it, because then the
Enamic blocks were born.
These blocks will quickly
find their place in the tool
belt of CEREC restorative
dentists. The new design
actually prevents micro-
cracks from propagating
and thus prevents the failure
of the restoration.
Dr. Giordano has shown, in vitro,
that Enamic can be milled to 1 mm thick-
ness and be the highest strength of any
milled restoration on the market. To me,
this means Enamic will be the most robust
restorative material for any dental restor-
ative procedure. A plus for these resto-
rations is that you do not have to use a
furnace to harden, crystallize or glaze; on
the flip-side of that, you cannot glaze the
restoration easily. This can be overcome by
usingmultiple grits of rubber
wheels and diamond pastes
(Figs. 3-4). Also, a stain-and-
glaze kit can be purchased to

Here is an inlay on #19 (Figs. 5-6). I
used the HT A1 because I feel the trans-
lucent restorations are just too flat. The
high-translucent restorations do seem to
blend better, particularly when you create
a feather edge. This technique is achieved
by increasing the margin thickness in the
design phase and polishing it thin.
The next case is an inlay on #3 and a
