Assessment of Dentoalveolar Compensation in Subjects with Vertical Skeletal Dysplasia: A Retrospective Cephalometric Study

Abstract

Objective: This study was aimed at understanding the differences in dentoskeletal parameters in short face and long face individuals and to evaluate the factors governing overbite. Materials and methods:Pretreatment lateral cephalograms of 80 individuals were traced and analyzed. The sample was divided into four groups: -short face male, short face female, long face male and long face female. The descriptive data for all the groups were obtained. Student's t-test (unpaired) was used to compare the dentoskeletal parameters of the groups and correlation analysis was used to study the factors governing overbite.Results: In this study, it was found that there were highly significant differences in the dentoskeletal parameters among the short face and long face groups. It was also revealed that not all short faces had deep bite and, similarly, not all long faces had open bite. Conclusion:Overbite was governed by a multitude of factors. In the long face group, the major factors governing overbite were lower anterior facial height and the height of anterior mandibular alveolar process. On the contrary, in the short face group, ANB angle and overjet were the governing factors. This study further highlights the interaction between the vertical and sagittal component of malocclusion.
