Among the children(Hellman's dental age ¥²a) with anterior crossbite, ten successfully
treated with the functional regulator of Fr nkel type ¥² were selected for this study.
And their pretreatment and posttreatment lateral head cephalometric films and study
models were compared and analyzed with those of children with normal occlusion. The
results obtained are as follows :
1. The most obvious treatment effects and changes are mainly dentoalveolar.
2. In maxilla, the only , skeletal finding is the slight increase of SUA. Other significant
skeletal change cannot be found .
3. Mandible tends to rotate downward and backward, for there is increase of mandibular
plane angle and maxillomandibular plane angle,
4. The increase of facial convexity angle and the change of the relation of the lips to
the Ricketts' esthetic line lead to improvement of the facial profile.
5. There is some increase of intermolar width at both arches, which shows the lateral
expansion effect probably due to the vestibular shields.
