Hi everyone,

I would like to obtain the coronal contour of teeth on a plane, by orienting them all according to a gaussian best fit plane passing through the cervix and then create a new parallel plan.

The aim is then to export this contour to perform 2D GMM .

For another purpose, this study has carried out these steps on former INSPECT GOM. [A dental revolution: The association between occlusion and chewing behaviour](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0261404)

Is there a way of performing these steps on 3DSlicer?
