However, neurosensory disturbances following surgical intervention near the mental foramen (MF) can occur in up to 43% of cases. Understanding anatomical variations of the MF is crucial to preventing surgical complications. Traditional two\u2010dimensional radiographs have limitations in accurately visualizing anatomical structures, whereas cone\u2010beam computed tomography (CBCT) provides high\u2010resolution three\u2010dimensional imaging that enhances diagnostic accuracy and clinical decision making. This case report highlights such a scenario.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A 54\u2010year\u2010old male referred for implant placement underwent preoperative evaluation with CBCT, which revealed a rare anatomical variation: the MF was positioned distal to the right mandibular second incisor (distal to #25) roughly 3\u00a0mm from the crest of the ridge, rather than its typical between the apices first and second premolars. The mental nerve exhibited an aberrant course, traversing in a superficial, buccal direction along the alveolar crest of site #25. This variability placed the neurovascular bundle at an extremely high risk for intraoperative injury. Consequently, the implant treatment plan was modified to reposition the implants away from the nerve pathway, and a customized CBCT\u2010based surgical guide was utilized to facilitate accurate implant placement while preserving neurovascular integrity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The patient exhibited no neurosensory disturbances postoperatively, and a 2\u2010week follow\u2010up showed normal healing. The adjusted implant placement strategy successfully avoided nerve injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Conventional radiographs are limited in detecting neurovascular structures and anatomical variations. CBCT serves as an essential diagnostic tool for identifying rare variations of the MF, ensuring precise implant placement, and preventing surgical complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain language summary<\/jats:title>\n                    <jats:p>Before placing dental implants, its important to know exactly where key structures are located to avoid causing injury. This case reports on a 54\u2010year\u2010old man who needed dental implants in his lower front jaw. The mental nerve was not identified with conventional radiography, but this was not a crucial issue since the implants planned were lower front teeth. Cone\u2010beam computed tomography (CBCT) revealed that the mental foramen was in an unusual spot\u2014closer to the front teeth, where the implant was planned. If this had gone unnoticed, the surgery could have certainly damaged the nerve, potentially causing permanent numbness. Thanks to the detailed imaging from the CBCT scan, the treatment plan was changed to avoid the nerve. The surgery went smoothly, the patient had no nerve problems afterward, and healing was normal.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/cap.70002","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T18:50:42Z","timestamp":1753728642000},"page":"374-380","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A rare mental foramen variation and the role of cone\u2010beam computed tomography in preventing nerve injury: A case report"],"prefix":"10.1002","volume":"16","author":[{"given":"Magdalena","family":"Orlowska","sequence":"first","affiliation":[{"name":"Department of Periodontics and Oral Medicine School of Dentistry, University of Michigan  Ann Arbor Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5427-8220","authenticated-orcid":false,"given":"Hend","family":"Abulatifa","sequence":"additional","affiliation":[{"name":"Department of Periodontics and Oral Medicine School of Dentistry, University of Michigan  Ann Arbor Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5067-7317","authenticated-orcid":false,"given":"Muhammad H.
