| ABSTRACTBackground: This study aimed to establish the cephalometric norms for Iraqis using McNamara's analysis and to verifythe existence of sexual dimorphism.Materials and Methods: 75 dental students, (33 males and 42 females) having normal occlusion, were chosen for thisstudy. Each student was subjected to clinical examination and digital true lateral cephalometric X-ray. Theradiographs were analyzed using AutoCAD program 2006 to measure the distances and angles. Descriptive statisticswas obtained for the measured variables for both genders and independent- samples t-test was performed toevaluate the genders difference.Results and Conclusions: The maxilla is protrusive in males in comparison with females, the effective midface andmandibular lengths, lower facial height are significantly higher in males, and the Frankfort mandibular plane angle issignificantly higher in females. The females show retrusive mandibles with slight retrusive upper incisors in comparisonwith males, while both genders show the same lower incisor position.Key words: McNamara's analysis, cephalometric norms.
