From the first interview to the diagnostic summary
A structured approach to the orthodontic history and the extra- and intra-oral examination, for dental students and young orthodontists. Each part ends with a quiz built on short clinical cases.
Every course is built around work you complete and are scored on, like tracing a cephalogram, so you find out what you cannot yet do while it still costs nothing.
Where an exercise has a measurable answer you get the number: landmark error in millimetres, calibrated from the image, not a tick or a percentage that tells you nothing about where you went wrong.
Reference tracings come from expert-annotated research datasets, and every norm is cited to the author who published it.
Courses run on cases we supply. Nothing here is intended for diagnosis or treatment planning, and you never upload a patient of your own.
