Cranial base angulation in Brazilian patients seeking orthodontic treatment

The relationship between cranial base flexion and facial prognathism has been of interest to orthodontists, orthognathic maxillofacial surgeons, and plastic surgeons. This study aimed to identify the cranial base flexion of adults with anteroposterior skeletal disharmony. Because the sample was representing a mixed racial population, the authors performed an investigation to confirm an association with other researches performed in different parts of the world. The results revealed an increase in the cranial base flexion in cases diagnosed as class II skeletal pattern and reduction in the group with class III skeletal pattern. These findings suggested that the characteristics of the Brazilian cases did not differ from some other studies despite various influences of different ethnicities in that population.
