Determining skeletal parameters in angle classes II, division 1 and II, division 2.
OBJECTIVE
Aim of the study was to find out whether significant differences in skeletal morphology exist between Angle Class II, Division 1 and II, Division 2.


METHODS
Fifty-nine patients without previous orthodontic treatment showing Class II occlusion and distobasal jaw relation were evaluated by cephalometric analysis.


RESULTS
Significant differences existed in skeletal morphology between patients with Angle Class II, Division 1 and II, Division 2, with only minor gender-specific differences: angleML/NSL in Class II, Division 2 males (p < 0.01) and females (p < 0.05) was smaller compared to Class II, Division 1 patients. angleML/NL was also noticeably smaller in Class II, Division 2 males (p < 0.001) and females (p < 0.01) compared to Class II, Division 1 patients. Patients with Class II, Division 2 had a smaller gonial angle (angleArGoMe), with the difference being significant only in males (p < 0.05).
