Compare chin bone orientation between the pre-operative planning and post operative result

f at least two of the angles have limited range (one is not more than 70-80 degrees, and one is not more than 10-15 degrees). For example, it works well for ships, because there is a practical limit on how much a ship can rotate around two of its axes.

For general applications, 3D rotation should not be described using roll/pitch/yaw angles, as it is

How can i measure the yaw, pitch and roll for bone advancement of the chin to compare between the pre-operative planning and post-operative result ( material provided is in form of STL

You can register the bones in the two positions (using “fiducial registration”, optionally followed by surface-based automatic “Model registration”) and then you can get information about the rotation component of the transform using “Characterize transform matrix” module (in Sandbox extension).
