This study assesses the validity of a new bite force measuring device (prototype of loadpad\u00ae, novel GmbH) and evaluates its feasibility in patients after segmental mandibular resection. Accuracy and reproducibility were analyzed with two different protocols using a universal testing machine (Z010 AllroundLine, Zwick\/Roell, Ulm, Germany). Four groups were tested to evaluate the impact of silicone layers around the sensor: no silicone (\u201cpure\u201d), 2.0 mm soft silicone (\u201c2-soft\u201d), 7.0 mm soft silicone (\u201c7-soft\u201d) and 2.0 mm hard silicone (\u201c2-hard\u201d). Thereafter, the device was tested in 10 patients prospectively who underwent mandibular reconstruction using a fibula free flap. Average relative deviations of the measured force in relation to the applied load reached 0.77% (\u201c7-soft\u201d) to 5.28% (\u201c2-hard\u201d). Repeated measurements in \u201c2-soft\u201d revealed a mean relative deviation of 2.5% until an applied load of 600 N. Maximum bite force decreased postoperatively by 51.8% to a maximum mean bite force of 131.5 N. The novel device guarantees a high accuracy and degree of reproducibility. Furthermore, it offers new opportunities to quantify perioperative oral function after reconstructive surgery of the mandible also in edentulous patients.<\/jats:p>","DOI":"10.3390\/diagnostics13040586","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T04:25:28Z","timestamp":1675657528000},"page":"586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Clinical and Technical Validation of Novel Bite Force Measuring Device for Functional Analysis after Mandibular Reconstruction"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4221-4878","authenticated-orcid":false,"given":"Claudius","family":"Steffen","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katharina","family":"Duda","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dag","family":"Wulsten","sequence":"additional","affiliation":[{"name":"Julius Wolff Institute, Berlin Institute of Health, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1760-2599","authenticated-orcid":false,"given":"Jan O.","family":"Voss","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"},{"name":"BIH Charit\u00e9 Clinician Scientist Program, Berlin Institute of Health, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, BIH Biomedical Innovation Academy, Charit\u00e9platz 1, 10117 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8679-8775","authenticated-orcid":false,"given":"Steffen","family":"Koerdt","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanne","family":"Nahles","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4987-2913","authenticated-orcid":false,"given":"Max","family":"Heiland","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Checa","sequence":"additional","affiliation":[{"name":"Julius Wolff Institute, Berlin Institute of Health, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carsten","family":"Rendenbach","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Charit\u00e9\u2013Universit\u00e4tsmedizin Berlin, Corporate Member of Freie Universit\u00e4t Berlin and Humboldt-Universit\u00e4t zu Berlin, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2253","DOI":"10.1016\/j.joms.2010.10.043","article-title":"Quality of life of patients with segmental mandibular resection and immediate reconstruction with plates","volume":"69","author":"Okoturo","year":"2011","journal-title":"J.
