Figure 5: This is the shade taken from tooth #8,
the natural tooth that I will be prepping. Again,
the measurement from the middle third of the
tooth gives us an A2 reading on the Classical
scale, while the 3D-Master shade registers as a
2M2.5. That’s three different 3D-Master shades
that are being called an A2 by the Classical
system. In an instance such as this, I assure you
that our technicians can make a closer shade
match with a 3D-Master shade.

Figure 6: The all-new VITA 3D-Master
Linearguide is my shade guide of choice today.
Because my three shade choices are all in the
“2” family, I remove the 2 shade guide and
check to see how these shades compare to
the natural adjacent teeth. Even if tooth #7, #8
and #10 are all different shades, we will have
to make some compromise because #8 and #9
have to be identical to avoid asymmetry.

Figure 7: I decide on 2M2.5 as my final shade
for the BruxZir crowns on tooth #8 and #9.
Shade 2M2.5 is made by mixing 2M2 and 2M3
in equal amounts, something not possible in
the Classical system (there is no such thing as
A2.5). Even if the lab uses an A2 shade in the
material you request, they will have the 2M2.5
shade tab to help with characterization before
it leaves the lab. This is why 3D-Master shades
work better, even if the material you request is
only available in VITA Classical shades.
