Microsoft HoloLens 2 was used to track the patient's mandible in real\u2010time without markers, providing automatic alignment. This approach allowed detection from any angle and remained reliable even when parts of the mandible were obstructed. Accuracy was assessed by measuring hologram registration errors, and usability was compared with the clinical gold standard, calculated using an EM sensor in an in\u2010vitro study with eight surgeons.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The system achieved an average registration error of under 1.40\u2009mm and a precision of 1.15\u2009mm when measured against the clinical gold standard.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The AR system provides a promising, less invasive, cost\u2010effective alternative to traditional cutting guides in maxillofacial surgery, enhancing precision and efficiency.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/hsr2.70518","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T03:32:28Z","timestamp":1741750348000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Markerless Augmented Reality Guidance System for Maxillofacial Surgery: An Omnidirectional Tracking Method"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4113-5823","authenticated-orcid":false,"given":"Ewald","family":"Ury","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering KU Leuven Leuven Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wouter","family":"De Vos","sequence":"additional","affiliation":[{"name":"Department of Cranio\u2010Maxillofacial Surgery Antwerp University Hospital Edegem Belgium"},{"name":"Faculty of Medicine &amp;
