In the case of Ce-TZP, the surface was changed to be black after laser irradiation. EDX measurement revealed the reduction of more amounts of oxygen atoms on Ce-TZP compared to Y-TZP. Laser irradiated zirconia implants were inserted into the bone defects of rat femur during 4 weeks. As a control, large grid sandblasted and acid etching (blastedHF) implant was used. Laser treatment for Y-TZP provided greater degree of bone-implant contact ratio than blastedHF treated Y-TZP (p<0.05). In the case of Ce-TZP, however, laser treatment showed no clear effect on bone response.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"・2018(平成30)年度 科学研究費補助金 若手研究(B) 研究成果報告書","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究期間 (年度)：2017-04-01 – 2019-03-31","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究分野：歯科理工学","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"・研究成果の学術的意義や社会的意義 : 本研究では，ジルコニアインプラントの表面改質にナノ秒パルスレーザによる微細加工を応用したことにより，確実なジルコニアオッセオインテグレーションを実現できる可能性が示された．これらの研究結果は，各関連学会で広く研究発表し，機関雑誌に掲載することできた．これにより日本発のジルコニアインプラントの臨床応用への糸口になり得たと考えている．生体安全性が高いセラミックインプラントの実用化は多くの国民の健康寿命を延長し，QOL向上に寄与すると考えている．","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 : 17K17225","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-17K17225/","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":"2022-03-16"}],"displaytype":"detail","filename":"17K17225.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"17K17225","url":"https://tsurumi-u.repo.nii.ac.jp/record/1063/files/17K17225.pdf"},"version_id":"bdd3cf81-0197-4045-847f-d1ba03974533"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ジルコニア","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"インプラント","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"ナノ秒パルスレーザ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"表面改質","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"骨形成","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"オッセオインテグレーション","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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"HIROTA, Masatsugu","creatorNameLang":"en"},{"creatorName":"廣田, 正嗣","creatorNameLang":"ja"},{"creatorName":"ヒロタ, マサツグ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"HIROTA","familyNameLang":"en"},{"familyName":"廣田","familyNameLang":"ja"},{"familyName":"ヒロタ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Masatsugu","givenNameLang":"en"},{"givenName":"正嗣","givenNameLang":"ja"},{"givenName":"マサツグ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"809","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"50734860","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=50734860"},{"nameIdentifier":"809","nameIdentifierScheme":"WEKO著者ID"}]}]},"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":"骨および軟組織付着を目指した凹凸微細表面を有するレーザ加工ジルコニアインプラント","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"骨および軟組織付着を目指した凹凸微細表面を有するレーザ加工ジルコニアインプラント","subitem_title_language":"ja"},{"subitem_title":"Nanosecond-pulsed laser-treated zirconia implant with microgrooves for bone integration and soft tissue adhesion","subitem_title_language":"en"}]},"item_type_id":"10007","owner":"10","path":["160"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-03-16"},"publish_date":"2022-03-16","publish_status":"0","recid":"1063","relation_version_is_last":true,"title":["骨および軟組織付着を目指した凹凸微細表面を有するレーザ加工ジルコニアインプラント"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-08-02T00:03:25.472321+00:00"}
