The designs were done via Bioge-
neric; initial proposals with the 4.0 soft-
ware were all generated at the same time
with pleasing results (Fig. 9). They were
modified to improve the proportions and
angulations. The anterior overlay from
DentalCadProducts.com was used to
help with this. Restorations were milled
out of Triluxe from Vita. This mate-
rial has three bands of translucency that
help the dentist get the esthetic results
they want with minimal manipulation
and time. After trying in the restorations,
they were stained and glazed using Vita’s
Akzent system. Restorations were bonded
in with Scotchbond Universal and RelyX
ultimate, excess cement cleaned up and
margins polished. Then occlusion was
adjusted and the patient dismissed.
At a one-week follow-up, the occlu-
sion was checked and no adjustment was
required. I feel the precision of the Buccal
Bite articulation with the Omnicam has
improved over the previous versions.
The soft tissue response at this visit was
great, as can be seen in Figure 10. Patient
was happy with the look and wanted to
proceed with the lower restorations.
Patient returned for the lower arch
and, since we were doing two different
materials, a new approach was taken.
Anesthesia was given and, while waiting
for it to take effect, buccal bite images
were done followed by the opposing arch.
Optragate was used for the imaging to
help retract the lips and allow the tissue
surfaces to be picked up clearly. You can
see in the pre-op (Fig. 11) how the canine
and the incisors were worn by the old
restorations and parafunction. With the
reshaping of the maxillary teeth, we were
able to create a situation where we could
minimize the incisal reduction in order

dentalcadproducts.com was used to
gauge proportions.
