The degree of impaction was determined by the Pell and Gregory classification system, and the facial type was categorized by the facial axis angle.
15 In a "mesofacial" growth pattern, there is a relative harmony in these two directions, leading to a facial profile which is described cephalometrically by a 90(3) facial axis angle.
Facial profile was categorized on the basis of facial axis angle which is created by the lines Ba-Na and Pt-Gn.
Accordingly, an increase in the Y axis angle was also found, as well as in the anterior facial height and the lower-anterior facial height, indicating a vertical compensation of sagittal dysplasia similar to the one reported by Saadia (17) in a study in 112 patients between 6 and 12 years of age, who were treated with maxillary expansion and face mask showing an increase in FH-MP angle, SN-MP angle, and in Ricketts facial axis, although, as explained above, the orthopedic effect might be different.

7% improvement in the Ra and shadows north-south facial axis values with active treatment greater than vehicle control, as well as a trend for improvement in the Rz north-south facial axis parameter, showing a 68.
Specific cranial landmarks were identified, and measurements were made of various aspects of the basicranium (figure 1), maxilla (figure 2), and mandible (figure 3), as well as the facial height (figure 4) and the facial axis (figure 5).
These measurements include the angle of the mandibular plane, the angle of the mandibular arch, lower facial height, the angle of facial depth, and the angle of the facial axis.
