The relationship between cranial base angle and various malocclusion types

Abstract

Introduction: Scientific literature indicates that the entire craniofacial complex is influenced by the growth and displacement of the cranial base structures, exerting direct influence over them.  A number of authors have suggested that there is a relationship between the degree of cranial base flexion and type of malocclusion. Nevertheless, many times this is not the case and this point is subject to controversy. Hence the aim of the present study was to assess the relationship between cranial base flexure and skeletal class.

Material and Methods: Cranial base angles (N-S-Ar and N-S-Ba) were measured on lateral cephalometric radiographs of 151 orthodontic patients with different skeletal malocclusions

Results: In this study cranial base angle did not show statistically significant difference between the four groups studied.

Conclusions: The present study did not find any differences in cranial base angle among various sagittal malocclusion types and results showed that the cranial base flexure does not play a pivotal role in determining skeletal malocclusion.
