Abstract: Introduction: Curve of Spee is a naturally occurring phenomenon in the human dentition. This normal occlusal curvature is required for an efficient masticatory system. Objectives of the study: The purpose of this study was to analyse the curve of spee among patients seeking orthodontic treatment. Material and methods: This analytical study was conducted in December 2018 to February 2019 at Punjab dental hospital, Lahore and Punjab medical college, Faisalabad. The data was collected from 50 patients who were done with orthodontics treatment in the hospitals. The data was collected through a non-probability sampling technique. After clinical examination for evaluating criteria patients were enrolled for the study. Lateral cephlogram was recorded, taken in centric relation, surveyed and classified by observation into the three categories of vertical relationships as normal angle, high angle and low angle. Results: The data was collected from 50 patients of orthodontics treatment. T-test was applied to all the values for finding the depth of curve of spee. The depth of curve for high angle, normal angle and low angle was 2.34, 2.51 and 1.97 respectively. The mean over jet value for high angle was 1.9mm and for low angle was 1.6mm. Conclusion: It is concluded that there is a significant correlation between curve of Spee, over-bite and overjet. Value of angle of spee was high among normal angle group as compared to low and high.
