M e l e n d e z
the zirconium oxide custom abutments in
place — for the design of the final zirco-
nium framework (Fig. 17).
The design was done taking into consid-
eration the original bridge that had been
scanned in a Biocopy image catalogue (Figs.
18-20).
Once the frameworkhadbeenmilled,
e.max ceramic was stacked over the frame-
work. The case was finished and delivered
(
Fig. 21). The screw-retained temporary
bridge and the single temporary crown #9
were removed, and custom zirconium oxide
abutments screwed inplaced (Fig. 22).
Looking for the best result, Jay did
two bridges for me, one PFZ and another
CadOn. Both bridges were acceptable, but
the connectors between crowns with the
CadOn were too thick (Fig. 23). I ended
up cementing the PFZ, occlusion adjusted.
Jay articulated the case in a fully adjustable
articulator.Theanatomywasgreat(Fig.24)
and the patient was extremely happy.
And me? I was like Snoopy in the Macy’s
Thanksgiving Day Parade.
With this case we proved how tech-
nology simplifies the procedures, reduces
the time to delivery and reduces the level
of stress for the doctor and the staff — all
while increasing predictability and profit-
ability. As CEREC owners, we have an
advantage over the dentists next door; so
let’s maximize the potential of it.
There is room to grow. The CEREC is only
the first step. Get involved with the other
products. Like George Lucas, it is about the
vision of the future, and the future is bright
with CEREC, inLab, Connect and Galileos.

Fig. 22: Temporary bridge was removed
and custom abutments were screwed in
position. Tissue response was excellent.
Fig. 23: The lab technician fabricated
two different fixed prosthesis: a CadOn
bridge and another with a zirconium
oxide framework and stack ceramic. The
CadOn connectors were too wide.
Fig. 24: e.max crown #9 was bonded with
NX3 and Optibond XTR. The four-unit
bridge at this phase of the treatment was
cemented with a clear temporary cement.
Marginal integration of the framework
with the abutments is perfect.

a full rehabilitation around six years
ago when she came to my practice.
Very difficult case. CEREC, inLab and
Galileos were the keys to the success
of this treatment.
Fig. 18: A Biocopy image catalog was
opened with images of the original case.

before the milling process.
Fig. 21: e.max ceramic was stacked on the
zirconium oxide framework and the case
finished. Almost an exact replica of the
existing bridge. The previous bridge was
also used as reference to match the shade.
