Comparative evaluation and correlation of CVMI stages in Class II (vertical) and Class II (horizontal) cases with Class I malocclusion, as evaluated using 3D-DVT and lateral cephalogram

Abstract

Background: The cervical vertebrae have attracted the interest of orthodontists, as the cervical portion of the spine serves as a reference structure to guide the normal head position. Skeletal age is determined by examining changes occurring in the morphology of the cervical vertebrae. There is relatively little data available from all the examinations that compare cervical vertebral phases between the various malocclusions. The purpose of this study was to compare the cervical vertebral maturation index (CVMI) stages of skeletal Class I and Class II malocclusions in the horizontal as well as vertical growth patterns. With distinct malocclusions, however, there are differences in cervical vertebral phases. Aim: To evaluate, compare and correlate the skeletal maturation using CVMI stages in cases with Class II (horizontal and vertical) using 3D-DVT and lateral cephalogram. Methodology: In the present observational study, a total of 45 adult patients reporting at the Orthodontics department at a dental college and hospital set up in Wardha district and diagnosed with Class II Horizontal and/or Class II vertical will be recruited. The patients will be divided into three sub-groups and biosafety measures will be taken. Conclusions: This study would give us a scope to compare the efficiency of lateral cephalogram versus 3D-DVT in estimating the skeletal maturity of patients who need to undergo growth modification in the orofacial region and orthodontic treatment.
