M0 step 6: Read your score band by band

Loading 3D view…

M0 step 6 of 6 · No instrument

Read your score band by band

Each checkpoint comes back acceptable, marginally substandard or critically deficient, with the reading next to the band. A checkpoint outside the band links to the step that fixes it.

Your last prep

Target
Occlusal reduction: 1.0–2.0 mm
Why
A reading just past a band edge is a different band; the card says which.
Watch
Where the sheet prints no number (adjacent tooth), the read is untouched or not, never a millimetre.

After the lesson: Retake the photos and score again on the 5 checkpoints.

Check 1 of 1 · Occlusal reduction
An occlusal reduction reads 2.3 mm. Which band is it in?
