If you are asking how to do tracing and analysis, you can easily perform cephalometric analysis by uploading a lateral ceph and do A.I. landmark digitization.

It seems to be necessary to prevent mesial movement of the mandibular first molar by using space maintainer. In addition, overgrowth of the mandible is observed, so it seems to be necessary to explain to the patient and their parents about the possibilities of orthognathic surgery when the patient's growth stops.
