The aim of this study was to comprehensively compare the influence of cross-sectional shape of ribbon arch wires with edgewise and round wires on intermaxillary traction in Class II malocclusion treatment using FEA simulation.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>The dentofacial structure was simulated in finite element software. A retraction force of 1.5\u00a0N was applied to different cross-sectional orthodontic arch wires: a ribbon wire (0.025\u2009\u00d7\u20090.017-in. and 0.025\u2009\u00d7\u20090.019-in.), a rectangular wire (0.017\u2009\u00d7\u20090.025-in. and 0.019\u2009\u00d7\u20090.025-in.) and a round wire (\u03a6 0.018-in. and \u03a6 0.020-in.).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Among the three groups, ribbon wire (0.025\u2009\u00d7\u20090.017-in. and 0.025\u2009\u00d7\u20090.019-in.) exhibited the lowest displacement in the X-axis (12.61\u00a0\u03bcm and 12.77\u00a0\u03bcm, respectively) and Z-axis (8.99\u00a0\u03bcm and 9.06\u00a0\u03bcm, respectively). However, the 0.025\u2009\u00d7\u20090.017-in. ribbon wire showed the highest Y-axis displacement. In the round wire group, \u03a6 0.020-in. wire displayed less rotation than \u03a6 0.018-in. wire, where the sagittal, frontal and occlusal rotation of \u03a6 0.020-in. wire was almost half of that of \u03a6 0.018-in. wire. The movement of the first molar region was intermediate between the ribbon arch group and the round wire group. Notably, the values of the 0.025\u2009\u00d7\u20090.017-in. arch wire displacement, which were higher than those of any other group, peaked at 0.019\u00a0mm in the central incisor region with a spike-like shape. The deformation range of the \u03a6 0.018-in. wire group was the largest in this study.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The cross-section of the arch wire influenced force delivery in Class II intermaxillary traction. With the same shape, a larger cross-sectional area led to less mandibular dentition movement. For the rectangular arch wire and ribbon arch wire groups, since the height and width were inverted, the vertical displacement of anchorage teeth in the ribbon wire group was reduced, but the possibility of buccal tipping in mandibular anterior teeth also increased.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12903-021-01859-8","type":"journal-article","created":{"date-parts":[[2021,10,7]],"date-time":"2021-10-07T22:43:58Z","timestamp":1633646638000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["The cross-sectional effects of ribbon arch wires on Class II malocclusion intermaxillary traction: a three-dimensional finite element analysis"],"prefix":"10.1186","volume":"21","author":[{"given":"Qin","family":"Xie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Duo","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,10,6]]},"reference":[{"issue":"5","key":"1859_CR1","doi-asserted-by":"publisher","first-page":"502","DOI":"10.1016\/S0889-5406(97)70287-7","volume":"111","author":"T Baccetti","year":"1997","unstructured":"Baccetti T, Franchi L, McNamara JA Jr, Tollaro I.
