Numerous cephalometric analyses have been applied to defined smaples of untreated individuals to derive cephalometric norms for a given population, usually grouped by age and ethnic origin. The data from such studies can be used cross sectionally for comparison during diagnosis and treatment planning. One hundred twenty-five individuals were examined in this study, and dentofacial norms for males and females with ideal occlusal and facial relationships were established. It should be stressed, however, that infinite combinations of den toskeletal relationships in each patient are possible to arrive at a face that is well balanced and that has an ideal occlusal relationship. The purpose of establishing cephalometric norms is not to create targets for individual treatment, but rather guides for the clinical assessment of the patient. The final diagnosis and treatment plan will rely on a number of other factors that cannot be obtained from a radiograph.
