Norms for anterior–posterior assessment of jaw relationship in Maharashtra population

Comparison of divesified angles for evaluation of sagittal skeletal discrepancy in Bihar population: A cephalometric study

“…Various studies have been conducted to assess the reliability of these parameters which can be used uniformly with accurate and reproducible results. 14 Formerly, ANB angle was widely used parameter but due to certain drawbacks like during growth the position of nasion is not fixed and any displacement of nasion will directly affect the ANB angle, furthermore, it is not a favourable one now a days. Rotation of jaw either by normal growth pattern or orthodontic treatment can directly alter the value of ANB angle.…”

“…Rotation of jaw either by normal growth pattern or orthodontic treatment can directly alter the value of ANB angle. 5,7,10,14 Wits appraisal came into existence as a substitute for ANB angle which is independent of cranial landmarks and even does not get affected by rotation of the jaws but this one also has a drawback of difficulty encounter in identifying the functional occlusal plane, which can be unfeasible at times. 15 Further, to overcome these demerits, a new Beta angle was introduced.…”

“…For the reason being, clinicians might hesitate to use Beta angle is because tracing the condyle and locating its center accurately is a tedious process. 14 After so many shortfalls of previous parameters, W angle and Yen angle were introduced which do not employ A and B points as skeletal landmarks, which further affected by local remodelling due to orthodontic treatment. 11,12 In the present study we traced the lateral cephalogram of 90 individuals of different class groups.…”
