Predictability of MKG Angle and Comparison with ANB Angle, W Angle, Yen Angle, Beta Angle and Pi Angle A Cephalometric Study

Introduction: The goal of this study was to develop a novel cephalometric estimation to assess the sagittal relationship between the maxilla and mandible. Methodology: Fifty pre-treatment lateral cephalograms were chosen and classified into classes I, II, and III based on ANB angle, W angle, Beta angle, and Pi angle. The MKG angle was calculated by connecting the lines drawn from point M to key ridge (k) and point KR to point G. The MKG angle was measured in order to compute the mean and standard deviation. Results: The results showed that MKG angle in the range 51º–59º can be considered to have a class I skeletal pattern. The MKG angle more than 59º indicates a class II skeletal pattern and less than 51º indicates class III skeletal pattern. Conclusion: The MKG angle can be used as a dependable marker to assess sagittal jaw discrepancy.
