Furthermore, short fiber filled epoxy (SFFE), solid rigid polyurethane (SRPU50), bovine femur, and porcine iliac bone were evaluated as substitute materials. In total, 57 tests in human specimens and 180 tests in the substitute materials were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In human temporal bone, average pull-out forces ranged from 220\u2009N to 285\u2009N between screws. Joint stiffness in human temporal bone ranged between 14 N\/mm and 358\u2009N\/mm. Statistically significant differences between the tested screws were measured in terms of stiffness and elastic energy. One screw type failed insertion due to tip breakage. No significant differences occurred between screws in maximum pull-out force. The average pull-out values of SFFE were 14.1\u2009N higher compared to human specimen.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Orthodontic miniscrews provided rigid fixation when partially inserted in human temporal bone, as evidenced by pull-out forces and joint stiffness. Average values exceeded requirements despite variations between screws. Differences in stiffness and elastic energy indicate screw-specific interface mechanics. With proper insertion, orthodontic miniscrews appear suitable for microstereotactic frame anchoring during minimally invasive cochlear implant surgery. However, testing under more complex loading is needed to better predict clinical performance. For further pull-out tests, the most suitable substitute material is SFFE.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/19160216241248669","type":"journal-article","created":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T03:40:23Z","timestamp":1718941223000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Pull-Out Strength of Orthodontic Miniscrews in the Temporal Bone"],"prefix":"10.1177","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8885-1154","authenticated-orcid":false,"given":"Christian","family":"Menke","sequence":"first","affiliation":[{"name":"Department of Pediatric Kidney, Liver and Metabolic Diseases, Hannover Medical School, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcel","family":"Kluge","sequence":"additional","affiliation":[{"name":"Otojig GmbH, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bastian","family":"Welke","sequence":"additional","affiliation":[{"name":"Laboratory for Biomechanics and Biomaterials, Department of Orthopaedic Surgery, Hannover Medical School, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Lenarz","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology and Cluster of Excellence, \u201cHearing4all,\u201d Hannover Medical School, Hannover, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omid","family":"Majdani","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Medizincampus Wolfsburg der Universit\u00e4tsmedizin G\u00f6ttingen, Wolfsburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7223-3618","authenticated-orcid":false,"given":"Thomas","family":"S.
