In the present study, 2 groups of 50 patients each were taken. First group comprised of patients with class I skeletal and dental malocclusion and second group of class II skeletal and dental malocclusion. Pre-treatment study models for both the malocclusions were selected on the basis of specific inclusion and exclusion criteria. The goal of my study was to determine and compare discrepancy for anterior and overall ratios among class I and class II malocclusions and also compare the values obtained with Bolton's standard values.
