Although chin deviation was assessed on the basis of the ANS-to-menton line on frontal cephalograms, its contributing factors were evaluated on three-dimensional CT images. Maxillary height, ramus length, frontal ramal inclination, lateral ramal inclination, mandibular body length, and body height were defined on each side, and right-left differences were calculated and analyzed.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Results:<\/jats:title>\n          <jats:p>In an assessment of chin deviation, subjects in this study showed predominantly left side deviation regardless of the group, and the degree of menton deviation did not reveal significant differences between groups. In a comparison of right-left differences in contributing factors, all values were noted to be greater in the retrusion group, except for body height, which showed no difference between chin-deviated and contralateral sides. In particular, ramus length presented a statistically significant difference between the two groups.<\/jats:p>\n        <\/jats:sec>\n        <jats:sec>\n          <jats:title>Conclusion:<\/jats:title>\n          <jats:p>Based on the same degree of chin deviation in mandibular prognathism and retrusion in this study, results of right-left differences in contributing factors indicate that chin deviations are expressed easily in mandibular prognathism, whereas they occur only with significant right-left differences in relevant maxillofacial structures in individuals with mandibular retrusion.<\/jats:p>\n        <\/jats:sec>","DOI":"10.2319\/112210-681.1","type":"journal-article","created":{"date-parts":[[2011,6,7]],"date-time":"2011-06-07T15:22:58Z","timestamp":1307460178000},"page":"988-993","source":"Crossref","is-referenced-by-count":55,"title":["Maxillofacial characteristics affecting chin deviation between mandibular retrusion and prognathism patients"],"prefix":"10.2319","volume":"81","author":[{"given":"Eun-Jeong","family":"Kim","sequence":"first","affiliation":[{"name":"Research fellow, Case School of Dental Medicine, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
