Maxillary complex, periodontium, orthodontic accessories, IZC miniscrews and an orthodontic wire were digitally created. The PAs were placed between canines and lateral incisors and projected at 4, 7, and 10\u00a0mm height distances. After that, distalization forces were simulated between PA and IZC miniscrews.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The anterior teeth deformation produced in the FEA models was assessed according to a Von Mises equivalent. The stress was measured, revealing tendencies of initial maxillary teeth movement. No differences were found between the right and left sides. However, there was a significant difference among models in the under-stress areas, especially the apical and cervical root areas of the maxillary anterior teeth. More significant extrusion and lingual tipping of incisors were observed with the 4\u00a0mm power arm compared to the 7\u00a0mm and 10\u00a0mm ones. The 10\u00a0mm power arm did not show any tendency for extrusion of maxillary central incisors but a tendency for buccal tipping and intrusion of lateral incisors.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The maxillary incisors and canines have different immediate movement tendencies according to the height of the anterior point of the en-masse distalization force application. Based on the PA height increase, a change from lingual to buccal tipping and less extrusion tendency was observed for the incisors, while the lingual tipping and extrusion trend for canines increased.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40510-024-00509-3","type":"journal-article","created":{"date-parts":[[2024,3,11]],"date-time":"2024-03-11T01:01:18Z","timestamp":1710118878000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Biomechanical analysis of total arch maxillary distalization using infrazygomatic crest miniscrews: a finite element analysis study"],"prefix":"10.1186","volume":"25","author":[{"given":"Alessandro","family":"Schwertner","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata Rodrigues","family":"de Almeida-Pedrin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thais Maria Freire Fernandes","family":"Poleti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paula","family":"Oltramari","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Cl\u00e1udia Ferreira","family":"de Castro Conti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fl\u00e1vio Augusto","family":"Cotrim-Ferreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guilherme","family":"de Almeida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos","family":"Flores-Mir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2684-0943","authenticated-orcid":false,"given":"Marcio Rodrigues","family":"de Almeida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,3,11]]},"reference":[{"issue":"4","key":"509_CR1","doi-asserted-by":"publisher","first-page":"492","DOI":"10.2319\/091717-624.1","volume":"88","author":"RN Mohamed","year":"2018","unstructured":"Mohamed RN, Basha S, Al-Thomali Y.
