Determination of the distance nasion-Axis orbital plane of a group patients from Santiago
Objectives: Determine in a random population distance Nasion -Axis orbital plane
Methods: A sample of 215 cephalometric profile of a radiology center of Santiago, 96 men and 119 women aged between 18 and 50 years was used. Patients were classified into dolicofacial, brachyfacial and mesofacial, according to the index Vert Ricketts, using Nemoceph software. In the cephalometric tracings, the distance between the nasion and the axis-orbital plane was measured.
Results: The average distance between nasion-axis orbital plane was 27 mm, with a standard deviation of 3.09. The group of men showed an average distance of 27.68 mm (SD = 3.07) and women of 26.44 mm (SD = 3.00). There were no statistically significant differences between groups according to the biotype.
Conclusions: The nasion- axis orbital plane distance varies between men and women and is not 23 mm as determined by the articulators facebow. This distance does not vary in the different facial types.
