Skeletal CI ¥² malocclusion is an orthopedic appliance mainly used for growing
children with maxillary undergrowth, which largely entails skeletal CI ¥² malocclusion.
It improves anterior crossbite and maxillary position and thus, enables patients to attain
favorable profile but often involves unfavorable profile with protrusive upper and lower
lips. Therefore, if orthodontists have knowledge of which condition helps obtain
favorable occlusion and profile, they are able to predict the prognosis and limitation of
the treatment.
This study was done in order to help obtain favorable profile after treating growing
skeletal CI ¥² children. In the study, we classified children into two groups, the one
with favorable profile(Group 1, n=12) and the other with unfavorable profile (Group 2,
n=14)and, with retrospective study using pre- and post- treatment lateral cephalogram,
drew the following conclusions.
1. As patients had more serious labioversion of upper incisors, they were more unlikely
to have favorable profiles after the treatment. Protrusion of prosthion, which was related
with maxillary incisors, also affected profiles.
2. As the NL-ML angle before the treatment was small, it was more likely to get
favorable profile.
3. As the degree of lower lip protrusion was high, it was likely to have bialveolar
protrusion after the treatment.
4. As the degree of downward and backward rotation of mandible was high, it was
likely to get unfavorable profile.
