Abstract: Objective: To introduce a novel perspective known as the CAP1 angle using Point W, M and G, which effectively assesses the sagittal skeletal interrelation between the maxilla and mandible, without being influenced by alterations in the vertical dimension. Materials and methods: In this orthodontic study, lateral cephalograms of 250 patients were examined to evaluate sagittal discrepancies. One investigator measured parameters like the ANB angle, Wit's appraisal, and Beta angle. After applying inclusion and exclusion criteria, 150 cephalograms were chosen and categorized into Class I, Class II, and Class III skeletal groups. Results: CAP1 angles between 19o and 25o, >250 and <19o suggest skeletal class I, II, and III malocclusions, respectively. Conclusion: CAP1 angle aids in diagnosis of true jaw discrepancy in sagittal dimension, thereby assisting in utilization of growth potential in children through implementation of precise therapeutic intervention.
