Aims and Objectives: To introduce K angle, a new cephalometric measurement to assess the sagittal jaw relationship. To define the mean value, the standard deviation for Kangle in people with the skeletal class I pattern and to determine whether there is a statistically significant difference between the mean value of Kangle between the skeletal class I, class II and class III groups. Materials and Methods: Seventy-five pretreatment lateral cephalograms (twenty-five each of Class I, II, and III) of patients between the age of 18 and 30 years were selected. They were again subdivided based on ANB and Wits appraisal into skeletal class I, class II, and class III groups, each group having twenty-five radiographs. The new measurement is based on the landmarks: Point M (midpoint of the anterior maxilla), Point G (center at the bottom of the symphysis) and apparent axis of the condyle (C). The K angle is the inferior angle measured at Point M, between the lines M-G and perpendicular from Point M to line C-G. Results: Subjects with K angle value between 40° and 46° were found to have a skeletal class I pattern. More acute angles implied skeletal class II pattern and more obtuse angles implied skeletal class III pattern. Conclusion: The K angle is an accurate, stable, reliable and reproducible parameter for the assessment of sagittal jaw relationship.
