The bonding surfaces were polished with a 600-grid silicon carbide paper and airborne-particle abraded using 110 µm alumina particles. Bonding specimens were fabricated by applying and firing either of the metal conditioners on the airborne-particle abraded surface, followed by firing porcelain into 5 mm in diameter and 3 mm in height. Specimens without metal conditioner were also fabricated. Shear bond strength for each group (n=8) were measured and compared (α=.05). Sectional view of bonding interface was observed by SEM. EDS analysis was performed to determine the chemical elements of metal conditioners and to determine the failure modes after shear test.\nRESULTS: There were significant differences among three groups, and two metal conditioner-applied groups showed significantly higher values compared to the non-metal conditioner group. The SEM observation of the sectional view at bonding interface revealed loose contact at porcelain-alloy surface for non-metal conditioner group, however, close contact at both alloy-metal conditioner and metal conditioner-porcelain interfaces for both metal conditioner-applied groups. All the specimens showed mixed failures. EDS analysis showed that one metal conditioner was Si-based material, and another was Ti-based material. Si-based metal conditioner showed higher bond strengths compared to the Ti-based metal conditioner, but exhibited more porous failure surface failure.\nCONCLUSION: Based on the results of this study, it can be stated that the application of metal conditioner is recommended for the bonding of porcelain to cobalt-chromium alloys.\n\nYoshito Minesaki, Sadaaki Murahara, Yutaro Kajihara, Yoshihisa Takenouchi, Takuo Tanaka, Shiro Suzuki, and Hiroyuki Minami\nEffect of metal conditioner on bonding of porcelain to cobalt-chromium alloy\nThe Journal of Advanced Prosthodontics 2016;8:1-8\nhttps://doi.org/10.4047/jap.2016.8.1.1", "subitem_description_type": "Other"}]}, "item_6_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "The Korean Academy of Prosthodontics"}]}, "item_6_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "20057806", "subitem_source_identifier_type": "ISSN"}]}, "item_6_source_id_9": {"attribute_name": "NII書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA12586908", "subitem_source_identifier_type": "NCID"}]}, "item_6_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "490", "subitem_subject_scheme": "NDC"}]}, "item_6_version_type_14": {"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_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "MINESAKI, Yoshito"}], "nameIdentifiers": [{"nameIdentifier": "143406", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MURAHARA, Sadaaki"}], "nameIdentifiers": [{"nameIdentifier": "143407", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KAJIHARA, Yutaro"}], "nameIdentifiers": [{"nameIdentifier": "143408", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TAKENOUCHI, Yoshihisa"}], "nameIdentifiers": [{"nameIdentifier": "143409", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TANAKA, Takuo"}], "nameIdentifiers": [{"nameIdentifier": "143410", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SUZUKI, Shiro"}], "nameIdentifiers": [{"nameIdentifier": "143411", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MINAMI, Hiroyuki"}], "nameIdentifiers": [{"nameIdentifier": "143412", "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": "2023-06-21"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "20057814_8_1-8.pdf", "filesize": [{"value": "1.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_9", "mimetype": "application/pdf", "size": 1500000.0, "url": {"label": "20057814_8_1-8", "url": "https://ir.kagoshima-u.ac.jp/record/16785/files/20057814_8_1-8.pdf"}, "version_id": "a1be772a-b13f-4400-b087-022d29f4a912"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Dental porcelain", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Chromium alloys", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Shear strength", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Effect of metal conditioner on bonding of porcelain to cobalt-chromium alloy", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effect of metal conditioner on bonding of porcelain to cobalt-chromium alloy"}]}, "item_type_id": "6", "owner": "29", "path": ["130"], "permalink_uri": "http://hdl.handle.net/10232/00032668", "pubdate": {"attribute_name": "公開日", "attribute_value": "2023-06-21"}, "publish_date": "2023-06-21", "publish_status": "0", "recid": "16785", "relation": {}, "relation_version_is_last": true, "title": ["Effect of metal conditioner on bonding of porcelain to cobalt-chromium alloy"], "weko_shared_id": -1}
