When titanium wires formed under different degrees of working are fabricated into abutments or fixtures, the thus prepared implant system would be constructed with different types of titanium materials. Since such an implant system with different titanium materials might cause undesired fracture, this situation should be avoided. In this study, three commercially available titanium wires (i.e., CPT3 with 3mm in diameter, CPT4 with 4mm in diameter, CPT5 with 5mm in diameter) were evaluated for their mechanical properties such as tensile strength, elongation, yield strength, energy to break and hardness. The following conclusion is obtained: 1. For tensile strength, CPT4 showed the highest value, while CPT3 had the lowest value. 2. However, CPT3 showed the greatest elongation while CPT4 showed the lowest value, which was below the specification value. 3. The yield strength of CPT4 was the highest, while CPT3 had the lowest value. 4. CPT3 exhibited the highest value of energy to break, suggesting that CPT3 is superior in toughness. 5. Hardness of CPT3 had the lowest value, while there is no significant difference between CPT4 and CPT5. 6. Metallographic observation demonstrated twin structures in CPT4, indicating that a residual strain was involved in their microstructures. 7. Based on the above, material suppliers and manufacturers should be aware of these data, and they should be required to provide titanium materials with constant mechanical properties.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "松本歯科大学学会"}]}, "item_2_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00232590", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0385-1613", "subitem_source_identifier_type": "ISSN"}]}, "item_2_version_type_20": {"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": "高橋, 恭彦"}, {"creatorName": "寺島, 伸佳"}, {"creatorName": "吉田, 貴光"}, {"creatorName": "出口, 雄之"}, {"creatorName": "伊藤, 充雄"}], "nameIdentifiers": [{"nameIdentifier": "0", "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": "2012-05-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "matsumoto_shigaku_31-02-04.pdf", "filesize": [{"value": "859.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 859100.0, "url": {"label": "matsumoto_shigaku_31-02-04.pdf", "url": "https://mdu.repo.nii.ac.jp/record/518/files/matsumoto_shigaku_31-02-04.pdf"}, "version_id": "290a5ece-f06b-4f12-aff0-7126fcd0d6b0"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "チタン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "インプラント", "subitem_subject_scheme": "Other"}, {"subitem_subject": "引張強さ", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "チタン棒材の直径と機械的性質の関係について", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "チタン棒材の直径と機械的性質の関係について"}]}, "item_type_id": "2", "owner": "3", "path": ["122"], "permalink_uri": "https://mdu.repo.nii.ac.jp/records/518", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-05-24"}, "publish_date": "2012-05-24", "publish_status": "0", "recid": "518", "relation": {}, "relation_version_is_last": true, "title": ["チタン棒材の直径と機械的性質の関係について"], "weko_shared_id": -1}
