title: Cephalometric floating norms for Czech adults.
abstract: The purpose of this study was to establish floating cephalometric           norms for the description of the individual skeletal pattern in Czech adults. Floating           norms provide a method of analysis that uses the variability of the associations           among suitable cephalometric measures, on the basis of the regression model           combining both sagittal and vertical skeletal parameters. Harmony box is a simple           and useful tool for diagnostics of orthodontic anomalies according to individual           cephalometric norms. 118 subjects, 53 male and 65 female, from Czech population           were selected. The method of multiple regression analysis was used to determine           interdependence among five cephalometric variables of the sample. Linear           regression equations with corresponding r2 and standard error of the estimate           (SE) were then illustrated as the harmony box. The results construct a harmony           box based on correlated cephalometric variables. The multiple regression analysis           of the data is graphically illustrated as a harmony schema which divides harmony           box in three zones according to the type of the face - prognathic, orthognathic           and retrognathic. The cephalometric floating norms describing the individual           craniofacial pattern among Czech adults were established based on five correlated           variables in the form of a harmony box.
