Comparison of Cervical Vertebral Body Volume in Class II Vertical and Class II Horizontal Cases With Class I Cases Using 3D-DVT

Abstract

The branch of orthodontics has had an interest in the cervical vertebrae wherein cervical spine is used as a reference structure for natural head position, so skeletal age was evaluated by studying variations in the cervical vertebral morphologies. Among all evaluations, very limited data is available wherein comparison between cervical vertebral body volumes between the different malocclusions has been done. This study aimed to compare the differences in the volumes of cervical vertebral bodies of C2, C3, and C4 between skeletal class I and class II malocclusions of both horizontal and vertical growth patterns. In class I the volume was significantly lesser as compared to class II. It was seen that there was statistically no significant difference in the volume between the horizontal and vertical growers. It can be concluded from this study that cervical vertebral body volume has no effect on growth pattern. However, variations in cervical vertebral body volume are seen with different malocclusions.
