Introduction: Malocclusions in sagittal dimensions are often associated with malocclusions in vertical dimensions i.e.; deep overbite which may be either dental or skeletal in nature, however a correct understanding of contributing factors towards the deep overbite is important in planning and execution of an appropriate treatment plan. Aims and Objectives: The aim of this study was to evaluate the various contributing factors towards the deep overbite in Class II division 1 malocclusion subjects and to analyze the significantly contributing factors and correlation between these factors. Material and Methods: Lateral cephalometric radiographs and study models of 60 patients with Class II division 1 malocclusion along with deep overbite were selected and various skeletal and dental components were measured on the lateral cephalometric radiographs and study models of these patients respectively. These measurements were statistically analyzed. Mean, Standard deviation, P value was calculated and correlations between these factors were evaluated. A P value of <0.001, was considered as statistically significant. Results: Descriptive statistical analysis was carried out and among the skeletal components gonial angle (P=0.0018) was the highly contributing factor towards deepbite with mandibular plane to frankfurt mandibular plane angle (P=0.0017) second highly contributing factor and among the dental components exaggerated curve of spee (P=0.0013) was the highly contributing factor while as other skeletal and dental components included in this study were least shared components to the deepbite malocclusion. Conclusion: Deep bite malocclusion has definite skeletal and dental components, among the skeletal components gonial angle, mandibular to frankfurt plane angle and among dental components exaggerated curve of spee were the significantly contributing factors towards deepbite while as other factors included in this study were least shared.
