developmental grooves in the restora-
tions. (Fig. 10). The restorations are then
milled on regular mill. Next, the sprue
is removed and the restorations tried in.
If the restoration needs more develop-
ment of the perikymata, then what was
done with the Incisal Variation tool a
diamond bur set to slow speed can be
used to create more texturing (Fig. 11).
The bur is taken across the surface to
create the grooves that mimic perky-
mata. The polishing starts with the
Ceraglaze green point, then blue and
finally the yellow point (Figs. 12-14). The
speed is between 8,000-10,000 RPMs.
This is used to remove the scratches
from milling in the developmental
grooves. The developmental grooves
are smoother and have a deeper value
due to this smoothness. Do not take any
of these wheels or points to any other
areas of the facial surface. If you do, you
will remove all the anatomy you so care-
fully put into place. After
the Ceraglaze, wheels or
points, the surface, other
than the developmental
grooves, will look rough.
That will be remedied
with the next steps.
To keep the anatomy
you want to, only use fine or softer
polishing pastes. I prefer to use fine
Diashine yellow paste (Fig. 15). This
is applied with a Robinson brush at a
slower rate of speed (6,000-8,000) and
light pressure (Fig. 16). Faster does not
mean better when it comes to polishing
and getting a high-gloss finish. If the
speed is too high, the heat build-up can
cause a fracture of the restoration. Slow
and steady wins the race.
The Diashine is then removed with a
piece of gauze saturated with alcohol.
What you will have now is a nice
gloss on the restoration and all
of the characterization that was
placed is still intact. If an even
higher gloss is desired, then use
a rag wheel to buff the surface
to a very high shine. The final
restoration has proper texture
and light reflex to look very
natural (Fig. 17). By mimicking

seated
the natural trends in the existing denti-
tion, and creating a surface texture and
luster to match the natural teeth, it is
possible to create a restoration that
blends in naturally without the use of
stains and glazes (Fig. 18). The system-
atic approach to texture and polishing
presented here makes this a predictable
treatment modality.
