[A study of craniofacial type of skeletal anterior crossbite in juveniles].
Lateral skull radiographs of 69 subjects with Class III malocclusion, 35 boys, 34 girls, aged 10-13 years old, were compared to a control group of similar mean age based on hierarchical cluster analysis. Cranial base, maxilla, mandible, relationships of sagital and vertical, teeth and soft tissue were evaluated together. Four subgroups of malocclusion were identified and described at the first time. The subgroup of maxillary deficiency, mandibular prognathism due to moved forward joint and lower anterior face height was the most common type. The results indicated that it should be evaluated a lot of indices together on cephalometric analysis.
