Head posture was dynamically measured on three axes (pitch, roll and yaw) using an Inertial Measurement Unit for precise 3D tracking. Malocclusions, including molar and canine sagittal relationships, overjet, overbite and crossbites, were assessed through standardised clinical examinations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All wheelchair\u2010bound participants showed significantly greater deviations in head posture compared to controls. The roll axis differed significantly across groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004), with the no control group exhibiting the greatest deviation. A significant correlation was observed between pitch axis deviation and sagittal molar relationships (\n                      <jats:italic>r<\/jats:italic>\n                      \u2009=\u2009\u22120.59,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006), indicating that a backward head posture was associated with Class II malocclusion, while a forward head posture was linked to Class III malocclusion. No significant correlations were found for the roll or yaw axes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Significant head posture deviations were detected in wheelchair\u2010bound individuals, with those having no head control showing more extreme deviations. This study found significant correlations between antero\u2010posterior head posture deviations and sagittal molar relationships in wheelchair\u2010bound individuals, suggesting that head posture could be a contributing factor to malocclusions in this population. Given the limited sample, these results should be interpreted cautiously.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/ocr.70098","type":"journal-article","created":{"date-parts":[[2026,1,14]],"date-time":"2026-01-14T09:37:37Z","timestamp":1768383457000},"page":"569-575","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of Head Posture in Wheelchair\u2010Bound Individuals and Its Relation to Malocclusion: A Proof\u2010of\u2010Concept Study"],"prefix":"10.1111","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3628-2209","authenticated-orcid":false,"given":"Kelly","family":"Billiaert","sequence":"first","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine University of Geneva  Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9075-8194","authenticated-orcid":false,"given":"Mustafa","family":"Al\u2010Yassary","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine University of Geneva  Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stavros","family":"Kiliaridis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine University of Geneva  Geneva Switzerland"},{"name":"Department of Orthodontics University of Bern  Bern Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6741-6922","authenticated-orcid":false,"given":"Gregory S.","family":"Antonarakis","sequence":"additional","affiliation":[{"name":"Division of Orthodontics, University Clinics of Dental Medicine University of Geneva  Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,14]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1754-4505.1994.tb01131.x"},{"issue":"2","key":"e_1_2_13_3_1","first-page":"159","article-title":"Orthodontic Treatment Need of Mentally Handicapped Children in Ibadan, Nigeria, According to the Dental Aesthetic Index","volume":"70","author":"Onyeaso C.
