Fig. 12: A2 Empress Multi was
milled and tried in. Lines
drawn on both the natural
tooth and the new crown to
visualize the contours
Fig. 13: The interproximal
contact marked
Fig. 14: The SD2 shade was
placed at the cervical and
blended up to the middle third
Fig. 15: SI1 is applied to the
incisal third to create
translucency; this is blended to
transition gradually into the
base shade of the restoration
Fig. 16: Small amount of SD2
shade is applied to the incisal
edge where there are small
areas of color at the edge
Fig. 17: White essence is applied
in vertical lines to mimic the
craze lines and natural white
areas that are present
Fig. 18: The SI2, which is purple
based, is mixed with a little bit
of the SI1 to create an enamel
effect characterization shade
Fig. 19: This is applied to the line
angles to create a light effect
at the line angles
Fig. 20: Final restoration cemented with Variolink Esthetic Clear
in the other anterior teeth (Fig. 17).
After the incisal area is characterized, it’s time to focus on the
line angles and central lobe. For this, I made a custom enamel
characterizing shade. I took the SI2, which is a light purple base,
and added just a little bit of SI2 and white to create a more blue-
purple shade (Fig. 18). This is used to highlight the line angles and
central lobe to give the look of an area of thickened enamel much
like what you would find in these areas (Fig. 19).
There are some areas that now do not have any shades or
essences applied to them. The glaze paste is then applied to
these areas to connect them. The restoration is then fired on the
Ivocolor cycle. Once the restoration has cooled, the blue and pink
twist polishers are used, then followed by DiaShine Fine polishing
paste and a rag wheel. The final restoration is cemented with Vari-
olink Esthetic Transparent cement (Fig. 20).
