What Osler Press is
A study tool that measures cross-sections of your own typodont crown preparations against a printed grid and places each number against the published bench-test criteria. It is not affiliated with any testing agency or school, it does not grade your exam, and it does not replace your faculty's judgement.

Numbers depend on your print scale, your photo and your taps. Check the 50 mm bar on every printed card.
Liability
