Background: There is an abundance of contradictory data regarding the relationship between the value of the cranial base angle, the type of malocclusion and the degree of mandibular prognathism.
The aim of our study was to identify craniofacial differences between the classes of malocclusion, to evaluate the relationship between the cranial base angle and lengths, the skeletal and dento-alveolar pattern.
Methods: A retrospective cephalometric study was carried out on 44 cephalometric radiographs to examine the contribution of cranial base angle and different linear and angular values in the four groups of malocclusion as classified by Angle. We measured the cranial base flexure, jaw position angles, the maxillary mandibular planes angle, the cranial base lengths and jaw lengths.
Results showed that the cranial base angle was significantly larger in class II division 1 subjects than in the class I group, mandibular length was found to be similar in class I and class II subjects, although it was significantly larger in the class III group and the cranial base angle was correlated inversely with maxillar and mandibular plane angles.
Conclusions: We found no correlation between the anterior cranial base length and maxillary and mandibulary prognathism.
