We report the case of a 62\u2010year\u2010old woman with trismus and difficulty in mastication caused by bilateral mandibular fractures. She had a maximal interincisal opening distance (MID) of 22\u2009mm. Mouth\u2010opening training was administered using a novel dental mouth\u2010training device custom\u2010made using ethylene vinyl acetate sheets and according to the dentition and extent of mouth\u2010opening of the patient. After 2 months of training, the MID increased to 42\u2009mm. With adequate training, this device is effective in treating trismus due to scarring.<\/jats:p>","DOI":"10.1155\/2021\/8340485","type":"journal-article","created":{"date-parts":[[2021,8,26]],"date-time":"2021-08-26T17:50:05Z","timestamp":1630000205000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Device of Ethylene Vinyl Acetate Sheet for Trismus Caused by Bilateral Mandible Fractures"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4324-2670","authenticated-orcid":false,"given":"Yoshiaki","family":"Ihara","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuka","family":"Nakamichi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichi","family":"Tashimo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinji","family":"Nozue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kota","family":"Hayashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mitsunori","family":"Ishiguro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Takahashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,8,26]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0278-2391(10)80104-1"},{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/014556131109001209"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.3109\/0284186X.2013.837583"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100125149"},{"key":"e_1_2_7_5_2","first-page":"2120","article-title":"Studies on the conservative treatment of condylar fracture of the mandible","volume":"31","author":"Yamaguti K.","year":"1985","journal-title":"Journal of the Japanese Stomatological Society"},{"key":"e_1_2_7_6_2","first-page":"1228","article-title":"Evaluation of trismus after maxillomandibular fixation for mandibular fractures","volume":"39","author":"Tashiro T.","year":"1993","journal-title":"Journal of the Japanese Stomatological Society"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000114908.90348.f9"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/ger.12270"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpainsymman.2012.07.020"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12325-008-0007-0"},{"key":"e_1_2_7_11_2","first-page":"466","article-title":"A case of severe trismus due to cicatricial changes of the masseter muscle","volume":"49","author":"Hara S.","year":"2003","journal-title":"Journal of the Japanese Stomatological Society"},{"key":"e_1_2_7_12_2","first-page":"2666","article-title":"Efficacy of mouth opening exercises in treating trismus after maxillectomy","volume":"126","author":"Ren W.
