Which of the following cephalometric analysis does not reveal the severity of anteroposterior jaw dysplasia?

Down's analysis provides information by which we can determine whether the individual’s pattern shows comparatively harmonious relations or not and whether dysplasia present in a person is in the facial skeleton, the dentition or in both. Steiner concluded that it might not be possible to correct dentition according to ideal norms in non-growing patients whose skeletal relations cannot be altered. The imperative here is to come up with an acceptable compromise for the dentition, one that will mask the underlying skeletal deformity as much as possible. This can be achieved using Steiner’s sticks, which allow calculations to be carried out for a particular ANB value. In addition to commonly used sagittal discrepancy indicators, that is angle ANB, sagittal maxilla mandibular relationship should be reconfirmed with other variables which include WITS appraisal, A–B plane angle and beta angle.  Key Concept: Tweed’s analysis (originally undertaken in 1954) is primarily based on inclination of the mandibular incisors to the basal bone and the latter’s association with the vertical relation of the mandible to the cranium. Tweed’s analysis is clinically oriented. It does not directly assess the jaws.   Reference: Orthodontics: Diagnosis and Management of Malocclusion and Dentofacial Deformities 3rd O P Kharbanda, pdf no 1016,997,981,2463
