A study on the nose profile with respect to the skeletodental pattern / 대한치과교정학회지

The purpose of this study was to investigate the relationship of nose profile with respect to skeletodental pattern, by measured and analyzed statistically the lateral cephalograms of 95 females (13 to 30 years old ). The results were summerized as follows; 1. The antero-posterior factors of the nose - nasofrontal angle, nasofacial angle, and dorsal length / ala length ratio were different among the malocclusion groups 2. There were no significant correlation between the vertical nose factors and the skeletal factors 3. The Class I groups had a straight nose profile; the Class II groups had a convex profile ; the Class III groups had a concave profile.
