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

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

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