Cephalometric Analysis
Do a cephalometric analysis based on landmarks indicated in the 3D Viewer, or in the Frontal Ceph or Lateral Ceph viewers. To determine which landmarks are to be included by default in the analysis, select or clear the items in the Surgery ceph presets.
Note
The skin model must be available.
To start the cephalometric analysis:
Click Surgery Ceph 
on the Diagnose tab.
In the Surgery Ceph wizard, indicate the landmarks requested.
Tips
To adjust the bone threshold, click Bone Threshold and use the slider.
To skip indicating a landmark, click Next without indicating the landmark.
In the surgery ceph presets in the General Preferences dialog, define which measurements, planes, angles and ratios you wish to include in the cephalometric analysis. Based on this selection, the set of landmarks that you need to place is defined.
Continue indicating the landmarks according to the indications given in the wizard.
Click Finish.
