VITA Shade Converter — Classical A1–D4 ↔ 3D-Master
Pick the shade you already have and get the closest match in the other system — with an honest confidence rating, because VITA has never published a universal conversion table.
For the most consistent result we recommend confirming the shade with the Dentiphoto Digital Shade Guide — it reads both systems directly from the tooth and shows how far off the match is.
Why the numbers disagree
The two systems were never built to map onto each other
VITA classical A1–D4 (1956) was arranged empirically, by how often natural shades occur. VITA 3D-Master (1998) was built to cover the colour space at even intervals. VITA has never published a universal table between them — only “closest possible match” approximations, tied to specific product moulds. That is why this tool shows a confidence level instead of pretending every conversion is exact.
Reading the screen
If you use a Dentiphoto Digital Shade Guide
The device reads both systems from one measurement and colours the result by how close the match actually is.
Clean match. Use the shade as it is.
The tooth sits between two shades. The device shows both — the larger value is the closer match. On 3D-Master you can mix the two materials 1:1 or order the interpolated shade; on Classical, take the larger value, because classical shades cannot be mixed.
Large deviation. Don’t send it to the lab. Re-measure, or the tooth may sit outside the shade guide range altogether.
The E220 also shows a ΔE value — how far the tooth actually sits from the nearest shade. Your tabs give you a name. They can’t give you a number.

Before you convert anything
Getting the shade right
Seven things that decide whether the number you started with was worth converting.
-
01
Take the shade in the first 5–10 minutes, before the tooth dehydrates and lightens.
-
02
Middle third of the labial surface, perpendicular to the enamel, away from the gingival margin.
-
03
Avoid cracks, white spots, fluorosis, old fillings and specular glare.
-
04
Non-uniform tooth: read the cervical, body and incisal thirds separately and let the technician layer accordingly.
-
05
Use a standardised light source — and record the lighting conditions with the case.
-
06
Replace your shade tabs every 2 years. That is VITA’s own recommendation: the ceramic fades.
-
07
Judge the tooth, not the tab in isolation.
Three instruments, one decision
Three ways to call a shade
| Shade tabs, by eye | Cross-polarised photo | Digital shade guide | |
|---|---|---|---|
| What you get | A shade name | An image for the technician | Both systems, plus a ΔE value |
| Depends on room light | Yes — window, lamp, hour of day | Partly | No — its own light source |
| Repeatability | Varies between clinicians and hours | Moderate | Consistent when the tip is placed correctly |
| Best for | Simple cases, good light, time to spare | Complex layering, working with a technician | Confirming before the case leaves for the lab |
These aren’t alternatives — most dentists use all three. The tabs stay in your hand; the device is what tells you how far off you are before the case leaves for the lab.
Questions
Why does the tool say “medium” or “low” confidence?
Because the underlying mapping genuinely is uncertain for those shades. VITA publishes approximations tied to specific product moulds, not a colour-space formula, and in several cases two classical shades share one 3D-Master value. Ten of the sixteen classical shades convert cleanly; six do not, and we say so rather than hide it.
Is this an official VITA conversion?
No. VITA has never published a universal conversion table between the two systems. This tool is built from VITA’s own published approximations cross-checked against two independent sources, and it tells you how much each entry is worth.
Why do some 3D-Master shades return no classical equivalent?
Sixteen of the twenty-nine 3D-Master shades have no counterpart in A1–D4. The 3D-Master space is simply wider and covers teeth the classical guide cannot express. If your lab works in classical, send the 3D-Master value as well.
My device shows two shades that don’t match this table. Is it broken?
No. The device finds the closest match in each system independently from the same measurement, so the two fields can land a step or two apart on the VITA value scale. That gap is information: the wider it is, the less cleanly the tooth sits in either system. Use the Digital Shade Guide tab above to read it.
Can I send the converted shade straight to the lab?
On a high-confidence conversion, yes. On medium or low, confirm visually or measure the tooth directly first — that is exactly where remakes come from.
My shade guide is a few years old. Does that matter?
Yes. VITA recommends replacing shade tabs every two years — the ceramic fades, and a faded tab shifts every match you make with it.
