An outline of the model was fabricated from CT image data with the contours following extraction using the stress analysis software Mechanical Finder version 6.2 (Research Center of Computational Mechanics, Tokyo, Japan), followed by the construction of a three- dimensional maxillary model and fabrication of an extracted maxillary first premolar model. Four chronological models, immediately after tooth extraction, and after 1, 3, and 6 months, were fabricated by changing the CT values of the extracted area based on this model. A TAD was constructed in the mesial area of the upper first molar using SolidWorks software (Solid-Works, Tokyo, Japan). The upper first molar was constrained, and the upper canine was pulled in a distal direction towards the TAD at 1 N to analyze stress changes affecting the alveolar bone in the region of the extracted tooth. Stress affecting the alveolar bone in the extracted region peaked immediately after tooth extraction, and gradually decreased with time. On the other hand, stress concentration was observed in the mesial alveolar crest of the extraction socket and the stress increased with ossification of the extraction socket. These results suggest that when using TAD it is more beneficial to apply tractive force soon after tooth extraction for distal tooth movement.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第767号"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"大阪歯科学会"}]},"item_10006_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中島, 章宏"},{"creatorName":"ナカジマ, アキヒロ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Akihiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"67","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-01"}],"displaytype":"detail","filename":"kou_767_txt..pdf","filesize":[{"value":"729.2 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"学位論文","url":"https://osaka-dent.repo.nii.ac.jp/record/26/files/kou_767_txt..pdf"},"version_id":"f8b41aa7-9c09-4df5-a550-63a4bf5e4869"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-01"}],"displaytype":"detail","filename":"kou_767.pdf","filesize":[{"value":"184.3 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","url":"https://osaka-dent.repo.nii.ac.jp/record/26/files/kou_767.pdf"},"version_id":"16a411b5-736b-4ac8-9b03-973c8bf078be"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Temporary anchorage device","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Three-dimensional finite element method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Maxilla","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Effect of tractive force using a temporary screw type anchorage device in alveolar bone －Stress analysis using the three-dimensional finite element method－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of tractive force using a temporary screw type anchorage device in alveolar bone －Stress analysis using the three-dimensional finite element method－"}]},"item_type_id":"10006","owner":"14","path":["8"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-01"},"publish_date":"2016-08-01","publish_status":"0","recid":"26","relation_version_is_last":true,"title":["Effect of tractive force using a temporary screw type anchorage device in alveolar bone －Stress analysis using the three-dimensional finite element method－"],"weko_creator_id":"14","weko_shared_id":14},"updated":"2023-05-15T14:10:25.664713+00:00"}
