Condylar head inclination proved to be the most significantly
correlated condylar characteristics to facial morphology.
Hypodivergent pattern is dominant in Class II malocclusion.
Symphysis width dimension also vary in different Class II
malocclusion.SBL-PNS, Y -axis, Facial -Axis, PFH/AFH X100, Bjork
sum and Symphseal width are significant parameters which
discriminate between groups. Horizontal facial morphology was seen
in 45 % of cases, vertical 8.3% and normal was 46.7%. Facial types
of the Class II patients vary and it depends on the position of the
condyle in the fossa. It can be anteriorly or posteriorly placed,
depending upon the type of jaw bases. Glenoid fossa position also
changes; it can be cranially or caudally placed in class II
patients depending upon skeletal facial types. Symphysis width was
strongly related to the direction of mandibular growth. Symphysis
width varies in different types of facial types. Generally it is
wider in low angle subjects and narrow in high angle Class II
preadolescent patients.
