| Abstract | Introduction: The purpose of this study was to clarify morphologic differences between Caucasian and Hispanic mandibular clinical arch forms in Class I, II, and III malocclusions. Methods: The study included 60 Class I, 50 Class II, and 50 Class III patients from each ethnic group. Orthodontic study models were photocopied, scanned, digitized, and measured (4 linear and 2 proportional). The dental arches were classified into square, ovoid, and tapered forms to compare the frequency distributions between the 2 ethnic groups. Results: The Caucasians had a significantly smaller arch dimensions than the Hispanics, except for canine depth. Caucasians had a higher frequency of tapered arch form whereas Hispanics had a high frequency of square arch form. Conclusion: There is a significant difference between frequency of arch forms and arch dimensions of Hispanic and Caucasian patients. Specifically, there is no arch form unique to any of Angle classification or ethnic group. |
