Furthermore, differences between three retention protocols (group\u00a0I: removable appliances in both jaws; group\u00a0II: fixed 3\u20133 lingual retainers in both jaws; group\u00a0III: removable appliance in the maxilla and fixed 3\u20133 lingual retainer in mandible) were assessed with Wilcoxon signed-rank tests at 5%.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Directly after debonding, measured forces distribution were similar to published references for untreated samples. In the following, no significant difference was found between retention protocols\u00a0II and\u00a0III with regard to the asymmetry of the anterior occlusal forces. Both groups maintained an asymmetric force distribution in the anterior segment during the study period. There was also no difference between groups\u00a0II and\u00a0III in the distribution of occlusal forces for the posterior segments. Both retention concepts kept the symmetrical distribution of occlusal forces stable over the observation period. The retention concept of group\u00a0I demonstrated a\u00a0symmetrical distribution of occlusal forces in the anterior segment after debonding and this remained stable during the 3\u2011month period. In the posterior segment, no improvement of the initially asymmetric masticatory force distribution could be observed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>All three studied retention protocols showed stability in retaining their original symmetrical or asymmetrical occlusal force distribution posteriorly\/anteriorly during the 3\u2011month observation period. Therefore, an even distribution of occlusal forces should be the aim of the finishing phase, as no relative benefit of any single retention scheme in terms of post-debond improvement during the retention phase was seen.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s00056-023-00480-4","type":"journal-article","created":{"date-parts":[[2023,6,29]],"date-time":"2023-06-29T06:02:46Z","timestamp":1688018566000},"page":"1-13","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Changes in the distribution of occlusal forces in the course of the orthodontic retention phase","Ver\u00e4nderungen in der Verteilung der Okklusionskontakte im Verlauf der Retention"],"prefix":"10.1007","volume":"86","author":[{"given":"F.","family":"Fritz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Daratsianos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Bourauel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Spyridon N.","family":"Papageorgiou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"J\u00e4ger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2023,6,29]]},"reference":[{"key":"480_CR1","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-017-05788-x","author":"JO Agbaje","year":"2017","unstructured":"Agbaje\u00a0JO, Van de Casteele\u00a0E, Salem\u00a0AS, Anumendem\u00a0D, Shaheen\u00a0E, Sun\u00a0Y, Politis\u00a0C (2017) Assessment of occlusion with the T\u2011Scan system in patients undergoing orthognathic surgery.
