Numerous criteria in adults are reported for determining the occlusal plane from the extraoral in deficient prosthesis. However, we often decided the occlusal plane in younger patient by applying adult criteria, because there are no clear standards in children. Therefore, we aimed to develop an evaluation system of occlusal plane of children from facial form using three-dimensional image device in this study. Eleven students in elementary school (6 boys and 5 girls) without no history of dental caries and treatment on the molar teeth were selected. We made the occlusal plane plate for children, and the facial form were photographed with a super high speed three dimensional surface morphotype photographing apparatus (hereinafter referred to as 3 dMD). Three points on the occlusal plane plate inserted in the oral cavity were plotted as the virtual occlusal plane on the nasal point and the bilateral ear lower point using the 3 dMD analysis software. The plane made from these three points was taken as the occlusal plane. We tested the reproducibility of three points constituting the virtual occlusal plane, and calculated the variation of between individuals and within individuals. The angle between the two planes was -2.146 degrees for boys and -2.055 degrees for girls on the frontal plane, 4.206 degrees for boys and 1.168 degrees for girls on the sagittal plane. There was a significant difference of the sagittal plane between boys and girls. It was considered that it is possible to estimate the occlusal plane from the virtual occlusal plane obtained from the surface form of the maxillofacial face of children.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟歯学会","subitem_publisher_language":"ja"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00182415","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-0153","subitem_source_identifier_type":"PISSN"}]},"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":"君, 雅水","creatorNameLang":"ja"},{"creatorName":"Kimi, Masami","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"齊藤, 一誠","creatorNameLang":"ja"},{"creatorName":"Saito, Issei","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"澤味, 規","creatorNameLang":"ja"},{"creatorName":"Sawami, Tadashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"野上, 有紀子","creatorNameLang":"ja"},{"creatorName":"Nogami, Yukiko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"岩瀬, 陽子","creatorNameLang":"ja"},{"creatorName":"Iwase, Yoko","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"黒澤, 美絵","creatorNameLang":"ja"},{"creatorName":"Kurosawa, Mie","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中村, 由紀","creatorNameLang":"ja"},{"creatorName":"Nakamura, Yuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"中島, 努","creatorNameLang":"ja"},{"creatorName":"Nakajima, Tsutomu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"早﨑, 治明","creatorNameLang":"ja"},{"creatorName":"Hayasaki, Haruaki","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-01-23"}],"displaytype":"detail","filename":"47(2)_81-86.pdf","filesize":[{"value":"491KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://niigata-u.repo.nii.ac.jp/record/2000773/files/47(2)_81-86.pdf"},"version_id":"20332aff-246f-463e-a5c1-7743cf354bed"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"小児","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"咬合平面","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"三次元顔貌写真","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"顎顔面軟組織","subitem_subject_language":"ja","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"小児の顎顔面の表面形態を用いた咬合平面評価システムの開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"小児の顎顔面の表面形態を用いた咬合平面評価システムの開発","subitem_title_language":"ja"},{"subitem_title":"Development of the evaluation system of occlusal plane in children","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1674452119869"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-01-23"},"publish_date":"2023-01-23","publish_status":"0","recid":"2000773","relation_version_is_last":true,"title":["小児の顎顔面の表面形態を用いた咬合平面評価システムの開発"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-23T05:44:29.925616+00:00"}
