Determination of reference planes and measurement points on superimposed digital models for deviation assessment. The red line indicates a reference plane and the red dot indicates a point of measurement. The anatomical point of each reference plane is as follows. (A) A-point, (B) right mental foramen, (C) the lowest point of the right sigmoid notch, and (D) the lowest point of the left sigmoid notch. The starting point for the measurement points is the most superior or anterior point, with subsequent points automatically generated at the same interval.
