The subjects were consisted with 100 patients (40 males, 60 females) diagnosed as skeletal mandibular prongathism. Frontal soft tissue was classified by cluster analysis based on these measurement results and performed multi groups comparison about the result of the measurement item in each group. The measurements were performed using the points of facial structure and facial outline and all subjects were applied the cluster analysis based on the measurements results. We got 4 clusters; group A (N=22): Patients with asymmetry of the face outline and little asymmetry of the position of facial structure ; group B (N=9): Patients with asymmetry in both position of facial parts and facial outline; group C (N=29): Patients with slight asymmetry of the facial outline and the severe asymmetry around nose and upper lip regions in facial structure; group D (N=40): Patients with symmetric facial outline and the position of facial structure. Those results suggested that each group may have a morphological characteristics. Group A has the patients with severe mandibular deviation with little maxillary deviation. In contrast, group B has the patients with severe bimaxillary deviation. Group C may have partially maxillary deviation with little mandibular deviation and group D has little face asymmetry. This classification must be helpful for treatment planning of surgical orthodontics for mandibular prognathisms with facial asymmetry.","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":"本多, 綾子","creatorNameLang":"ja"},{"creatorName":"Honda, Ayako","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"高橋, 功次朗","creatorNameLang":"ja"},{"creatorName":"Takahashi, Kojiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"丹原, 惇","creatorNameLang":"ja"},{"creatorName":"Nihara, Jun","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"高木, 律男","creatorNameLang":"ja"},{"creatorName":"Takagi, Ritsuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"小林, 正治","creatorNameLang":"ja"},{"creatorName":"Kobayashi, Tadaharu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"齋藤, 功","creatorNameLang":"ja"},{"creatorName":"Saito, Isao","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":"2024-02-13"}],"displaytype":"detail","filename":"48(2)_75-83.pdf","filesize":[{"value":"553KB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://niigata-u.repo.nii.ac.jp/record/2001181/files/48(2)_75-83.pdf"},"version_id":"7b207b73-d473-4579-b163-7e97a3b33fa8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"下顎前突","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"クラスター分析","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"正貌規格写真","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"正貌軟組織","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":"クラスター分析による骨格性下顎前突症例における正貌パターンの分類","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"クラスター分析による骨格性下顎前突症例における正貌パターンの分類","subitem_title_language":"ja"},{"subitem_title":"Classification of frontal facial patterns in patients with mandibular prognathism","subitem_title_language":"en"}]},"item_type_id":"7","owner":"4","path":["456","1707786791908"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-02-13"},"publish_date":"2024-02-13","publish_status":"0","recid":"2001181","relation_version_is_last":true,"title":["クラスター分析による骨格性下顎前突症例における正貌パターンの分類"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2024-02-13T05:22:45.019235+00:00"}
