People with normal occlusion tend to have more brachyfacial than dolicofacial patterns. 2. Many of the norms vary significantly with the different facial patterns. When treating a patient, the norms used should reflect differences associated with the various facial patterns and sex. This will enable us to treat with fewer extractions with the confidence that the teeth and bony structure will remain stable. 3. Our findings re-establish and re-confirm our cephalometric standards for adults based on the individual's facial type as described by his or her vertical description of growth and ethnic type. We can be accurate in treating the patient to the clinical normal for that individual and not to an overall composite of the average.
