We have clinically applied the 4-dimentional muscle model to explore the pathology of MMTAH. In this study, we examined the relationship of the stress distribution of the mandibular body with the pathology of MMTAH. Concretely, it was analyzed by integration of the data of the patients’ mandibular movements into the individual finite element model reconstructed using the patients’ CT data. As a result, the maximum stress was concentrated on the coronoid process and the mandibular angle during mouth opening and mouth closing in the MMTAH patients. It is interesting to note that the portion of stress concentration was in accordance with that of the mandibular hyperplasia in the MMTAH patients.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"・2014(平成26)年度 科学研究費補助金 基盤研究(C) 研究成果報告書","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究期間 (年度)：2012-04-01 – 2015-03-31","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究分野：口腔外科","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10007_description_9":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号 : 24500559","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10007_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-24500559/","subitem_relation_type_select":"URI"}}]},"item_10007_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-04-29"}],"displaytype":"detail","filename":"24500559.pdf","filesize":[{"value":"215.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"24500559","url":"https://tsurumi-u.repo.nii.ac.jp/record/1203/files/24500559.pdf"},"version_id":"bc5e9208-46fa-418f-8921-b470e380293a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"有限要素法","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"4次元咀嚼筋解析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"咀嚼筋腱・腱膜過形成症","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_researcher":{"attribute_name":"研究代表者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中岡, 一敏","creatorNameLang":"ja"},{"creatorName":"NAKAOKA, Kazutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"有限要素法と4次元咀嚼筋解析システムによるスクエアマンディブルの病態解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有限要素法と4次元咀嚼筋解析システムによるスクエアマンディブルの病態解析","subitem_title_language":"ja"},{"subitem_title":"Etiological analysis of Square mandible by finite element method and 4-dimentional muscle model","subitem_title_language":"en"}]},"item_type_id":"10007","owner":"10","path":["181"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-04-29"},"publish_date":"2022-04-29","publish_status":"0","recid":"1203","relation_version_is_last":true,"title":["有限要素法と4次元咀嚼筋解析システムによるスクエアマンディブルの病態解析"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-02-01T02:29:57.272942+00:00"}
