However, few reports are available as to the change in vermilion lip morphology before and after orthodontic treatment. The aim of this study was to precisely investigate the changes of vermilion lips after orthodontic extraction treatment in Angle Class I bimaxillary dentoalveolar protrusion. Subjects consisted of 20 adult females diagnosed as Angle Class I bimaxillary protrusion and treated with bicuspids extraction orthodontic treatment for both dental arches. Frontal and lateral facial photographs taken before and after orthodontic treatment were utilized for linear and angular measurements. For linear measurements on lateral photographs, a X-Y coordinate system was constructed by using lateral cephalograms superimposed following profile line. FH plane was defined as X-axis and a perpendicular line to FH at alar curvature (Ac) point was drawn as Y-axis. The points related to vermilion lip were measured digitally on lateral photographs. Vermilion widths and angles of Cupid’s bow were measured on frontal photographs. The upper and lower vermillion border depths decreased by 2.3 mm and 3.6 mm respectively. The inter-vermillion angle significantly reduced by 8.7 degree. Although the vermilion lip heights slightly decreased, variations on individuals were found. In conclusion, upper and lower vermilions were retracted following anterior teeth retraction, but the different types of morphological changes between the upper and lower vermilion lips was observed in the present study.", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "学位の種類: 博士（歯学）. 報告番号: 甲第4293号. 学位記番号: 新大院博（歯）甲第378号. 学位授与年月日: 平成29年3月23日", "subitem_description_type": "Other"}, {"subitem_description": "Orthodontic Waves-Japanese Edition. 2016 Sep; 75(2).97-105", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博（歯）甲第378号", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "13101甲第4293号"}]}, "item_6_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学"}]}, "item_6_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "ETD"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "大森, 裕子"}], "nameIdentifiers": [{"nameIdentifier": "51063", "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": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "h28ndk378.pdf", "filesize": [{"value": "373.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 373100.0, "url": {"label": "本文", "url": "https://niigata-u.repo.nii.ac.jp/record/5904/files/h28ndk378.pdf"}, "version_id": "83f459a2-ba2b-408d-b780-3b046e0bff08"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-05"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "h28ndk378_a.pdf", "filesize": [{"value": "213.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 213900.0, "url": {"label": "要旨", "url": "https://niigata-u.repo.nii.ac.jp/record/5904/files/h28ndk378_a.pdf"}, "version_id": "3d58d61b-e902-458f-aafb-a762facf8246"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "赤唇", "subitem_subject_scheme": "Other"}, {"subitem_subject": "形態変化", "subitem_subject_scheme": "Other"}, {"subitem_subject": "矯正治療前後", "subitem_subject_scheme": "Other"}, {"subitem_subject": "上下顎前突", "subitem_subject_scheme": "Other"}, {"subitem_subject": "小臼歯抜去", "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": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "日本人を対象とした矯正歯科治療前後の赤唇に関する形態学的研究 : 小臼歯抜去により治療したアングルI級上下顎前突症例における矯正歯科治療前後の赤唇形態変化", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "日本人を対象とした矯正歯科治療前後の赤唇に関する形態学的研究 : 小臼歯抜去により治療したアングルI級上下顎前突症例における矯正歯科治療前後の赤唇形態変化"}, {"subitem_title": "日本人を対象とした矯正歯科治療前後の赤唇に関する形態学的研究 : 小臼歯抜去により治療したアングルI級上下顎前突症例における矯正歯科治療前後の赤唇形態変化", "subitem_title_language": "en"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "434"], "permalink_uri": "http://hdl.handle.net/10191/47639", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-08-18"}, "publish_date": "2017-08-18", "publish_status": "0", "recid": "5904", "relation": {}, "relation_version_is_last": true, "title": ["日本人を対象とした矯正歯科治療前後の赤唇に関する形態学的研究 : 小臼歯抜去により治療したアングルI級上下顎前突症例における矯正歯科治療前後の赤唇形態変化"], "weko_shared_id": 2}
