In recent years, computer-assisted surgery (CAS) has been widely adopted in surgery, including the removal of foreign bodies. Among various techniques, computer-aided design\/computer-aided manufacturing (CAD\/CAM) technology has been widely employed for hard tissue management in the oral and maxillofacial region, and reports on the application of CAD\/CAM technology for procedures involving soft tissues are lacking. In this study, we report a case in which CAD\/CAM technology is used to facilitate the removal of a foreign body located in the soft tissue.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Case presentation<\/jats:title>\n            <jats:p>A 25-year-old female underwent metal plate and screw removal in 2020; however, a metal fragment remained lodged in the buccal soft tissue on the left side of the lower jaw. Computed tomography (CT) revealed a high-density area, indicating a metal fragment measuring 1.5\u2009\u00d7\u20091.3\u2009\u00d7\u20092.5\u00a0mm. We identified the exact location of the fragment using preoperative CT data processed with Mimics<jats:sup>\u00ae<\/jats:sup> (Materialise). A surgical guide was designed using Magics<jats:sup>\u00ae<\/jats:sup> (Materialise) and fabricated using a 3D printer, enabling precise identification of the vertical and horizontal positions of the foreign body within the soft tissue. The use of CAD\/CAM technology facilitated accurate localization and rapid removal of the fragment. The operative time of removal was 1\u00a0h and 5\u00a0min. Minimal bleeding occurred, and the postoperative course was uneventful, with no signs of infection or nerve damage.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>This case demonstrates the successful application of CAD\/CAM technology for the identification and removal of a foreign body from soft tissue.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/s40902-025-00479-4","type":"journal-article","created":{"date-parts":[[2025,9,30]],"date-time":"2025-09-30T12:44:44Z","timestamp":1759236284000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Using computer-aided design\/computer-aided manufacturing technology for foreign body removal from soft tissues: a case report"],"prefix":"10.1186","volume":"47","author":[{"given":"Teruhide","family":"Hoshino","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuji","family":"Yoshida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chihiro","family":"Kurihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koki","family":"Oiwa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kotaro","family":"Tachizawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keisuke","family":"Sugahara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Katakura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,9,30]]},"reference":[{"key":"479_CR1","doi-asserted-by":"publisher","first-page":"410","DOI":"10.1007\/s12663-015-0860-8","volume":"15","author":"T Iwai","year":"2016","unstructured":"Iwai T, Mikami T, Yasumura K, Tohnai I, Maegawa J (2016) Use of occlusal splint for noninvasive fixation of a reference frame in orbital navigation surgery.
