Tooth measurement with SLICER

Hi everyone,
I am a dentist by profession and an orthodontist in making. I am doing a project where we are aiming to measure linear and angular tooth movement in all three planes of space by superimposing 3d scans of pre and post orthodontic(braces) treatment. I need some help with superimposition and then make the measurements. Can anybody please guide or help me with that?
Looking forward to your response.

Thank you.

Kind Regards,
Furqan Jamal

Hi Furqan

Iā€™m an ENT surgeon and a Slicer user for 2+ years and I would recommend to try the landmark registration first so you can have a sense how it can be done.
Then, I would try the elastix module to test the registration on your dataset.
The measurements may be done using the measurements tools from Slicer.
Hope it helps
