Questions about scoring, price and classes
What do I photograph?
Three photos of the prep on your school typodont: occlusal, buccal and lingual, at the same distance and light, plus the sectioned putty index for clearance.
Does it score against my school’s bench test?
It scores your crown prep on 5 checkpoints against the 2026–27 published crown-prep criteria for a molar, not your school’s own grading. Your school’s page shows the procedures, clock and teeth it published, with the source. 26 programs are listed.
What happens at my second scored prep?
Your first score is free with an account. The second asks for $99 for 90 days, one payment, no auto-renew, with a 14-day refund.
See pricingCan my class use it?
Yes. Faculty use Osler Press free: create a class code, assign lessons, and see each checkpoint’s within-criteria rate across the class and which checkpoint each student misses most. Students join with the code; a $149 a year seat opens the full library.
Create a class codeIs this an exam result?
No. Practice feedback against the 2026–27 published crown-prep criteria (molar). Not an exam or admissions result; your program and examiners decide.
