No clinical signs of peri\u2010implant complications were found, and overall treatment outcomes were positive for all patients. Satisfactory osseointegration was achieved, and no evidence of periapical pathology was noted on panoramic radiographs. The patients were notified about the apical implant fracture at the time of the surgery, and during follow\u2010up appointments, they were reassured about the absence of further complications in the long term. It was hypothesized that the increased risk of fracture was associated with high insertion torques (around 80\u2009N\u2009cm) and implant insertion in areas where the tip engages into a hard basal cortical bone (Types I\u2013II) with an inclined cortical surface in the lingual aspect of the alveolar bone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The incidence of apical fracture was low and did not result in any clinically relevant complications and may be detected during the surgery or in follow\u2010up radiographs. Although the intraosseous implant tip fragment may not be of major concern, additional caution to prevent excessive insertion torque and to avoid anatomical regions of higher risk may be advisable.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cid.70084","type":"journal-article","created":{"date-parts":[[2025,8,25]],"date-time":"2025-08-25T15:45:06Z","timestamp":1756136706000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Apical Fracture of One\u2010Piece Titanium\u2013Zirconium Mini\u2010Implant for Mandibular Overdenture: A Prospective 3\u2010Year Follow\u2010Up"],"prefix":"10.1111","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6812-4849","authenticated-orcid":false,"given":"Cl\u00e1udio Rodrigues","family":"Leles","sequence":"first","affiliation":[{"name":"School of Dentistry Federal University of Goias  Goiania Goias Brazil"},{"name":"Department of Reconstructive Dentistry and Gerodontology School of Dental Medicine, University of Bern  Bern Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1912-4217","authenticated-orcid":false,"given":"Thalita Fernandes Fleury","family":"Curado","sequence":"additional","affiliation":[{"name":"School of Dentistry Federal University of Goias  Goiania Goias Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Luiz Rodrigues","family":"Leles","sequence":"additional","affiliation":[{"name":"School of Dentistry Federal University of Goias  Goiania Goias Brazil"},{"name":"Clinical Practice  Goiania Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N\u00e1dia Lago","family":"Costa","sequence":"additional","affiliation":[{"name":"School of Dentistry Federal University of Goias  Goiania Goias Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4267-0515","authenticated-orcid":false,"given":"Manrique","family":"Fonseca","sequence":"additional","affiliation":[{"name":"Department of Reconstructive Dentistry and Gerodontology School of Dental Medicine, University of Bern  Bern Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9700-5534","authenticated-orcid":false,"given":"Martin","family":"Schimmel","sequence":"additional","affiliation":[{"name":"Department of Reconstructive Dentistry and Gerodontology School of Dental Medicine, University of Bern  Bern Switzerland"},{"name":"Division of Gerodontology and Removable Prosthodontics University Clinics of Dental Medicine, University of Geneva  Geneva Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8478-1673","authenticated-orcid":false,"given":"Gerald","family":"McKenna","sequence":"additional","affiliation":[{"name":"Centre for Public Health Queen's University Belfast  Belfast UK"},{"name":"Clinic of Special Care and Geriatric Dentistry University of Zurich  Z\u00fcrich Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,8,25]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/ID.0b013e318192cafe"},{"issue":"5","key":"e_1_2_10_3_1","first-page":"662","article-title":"Analysis of Incidence and Associated Factors With Fractured Implants: A Retrospective Study","volume":"15","author":"Eckert S.
