The technique of lateral cephalometric radiography has become widely used as a descriptive, analytical, and diagnostic tool in clinical orthodontics and prosthodontics. The application of numbers to the radiographic images readily gives the impression of mathematical accuracy. The purpose of study was to established sex-specific normative data for Czech patients in Prague. The 88 subjects (55 male and 33 female) were included in the study. 20 different measurements (computer analysis Kefalo 4.07) were used as determinates of the skeletal sagital jaw relationship. The subjects were divided into groups based on gender. Differences of mean values were tested using statistical tests. The data were compared with 12 different Caucasian European and American measurements. The statistical significant difference between European standard and Czech subjects was not found. Our findings support hypothesis that cephalometric norms are based on racial, age but not sex difference. Anterior and posterior facial heights were reduced due to less sufficient therapy.
