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_language":"en","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","subitem_publisher_language":"en"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"20057806","subitem_source_identifier_type":"PISSN"}]},"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","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murahara, Sadaaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kajihara, Yutaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takenouchi, Yoshihisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Takuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Minami, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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","filename":"20057814_8_1-8.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_9","mimetype":"application/pdf","url":{"label":"20057814_8_1-8","objectType":"fulltext","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","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["130"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-06-21"},"publish_date":"2023-06-21","publish_status":"0","recid":"16785","relation_version_is_last":true,"title":["Effect of metal conditioner on bonding of porcelain to cobalt-chromium alloy"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T06:33:18.357067+00:00"}
