However, in the case of funnel-shaped root canals, it is still unknown what type of build up is appropiate. The purpose of this study is to investigate the possibility of FRP posts to funnel-shaped root canals. As the experimental tooth for abutment build up, epoxy artificial maxillary lateral incisor was used. The artificial tooth was cut in the cervix and a funnel-shaped root canal with 8 mm length was formed in the root. As the materials for abutment build up, glass fiber reinforced plastic posts (Fiber Posts) 1.2mm, 1.4mm and 1.6mm in diameter, core resin and gold-silver-palladium alloy were used. Abutment build up was made in the following four different methods. 1. Build up with core resin and a Fiber Post of one of the three different diameters. 2. Build up with core resin and 1.2mm Fiber Posts with six variations in number and arrangement. 3. Build up only with core resin. 4. As control, build up with conventional metal core by casting of gold-silver-palladium alloy. Five specimens were prepared four of each method. The destruction test was carried out under the following condition. A load was added to the lingual surface of abutment. Loading direction was 45 degrees to the tooth axis. Cross head speed was 0.5 mm/min. After the test, the destruction patterns of specimens were observed. The results were as follows 1. There is no significant difference in the destruction strength among the abutments with Fiber Posts regadless of their diameter, number or arrangement posts. 2. All the destructions of the abutment tooth with a post were occurred in the root, and no specimen fractured in the post. 3. The specimens of low destruction strength fractured or cracked near the cervix of the tooth, whereas the specimens of high destruction strength fractured near the center of the root. Considering from the results of destruction strength and pattern, it was suggested that in the case of abutment build up in funnel-shaped root canal, it is necessary to consider the elastic modulus of building materials and the thickness of root dentin.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN1010214X","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Occlusal Rehabilitation, Ohu University Graduate School of Dentistry"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"原著論文"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Original Article"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"奥羽大学大学院歯学研究科咬合機能修復学専攻"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2008-06-01"}],"displaytype":"detail","filename":"KJ00005073474.pdf","filesize":[{"value":"800.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://ohu-lib.repo.nii.ac.jp/record/2782/files/KJ00005073474.pdf"},"version_id":"323bae84-27a0-4c94-b322-fdc4d245a462"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"funnel-shaped root canal","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"glass fiber reinforced plastic post","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"abutment build up","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"destruction strength","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"destruction pattern","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"漏斗状根管に対するガラス繊維強化樹脂ポストを応用した支台築造","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"漏斗状根管に対するガラス繊維強化樹脂ポストを応用した支台築造"},{"subitem_title":"Abutment Build up Using Glass Fiber Reinforced Plastic Posts in Funnel-shaped Root Canals","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["118"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-06-01"},"publish_date":"2008-06-01","publish_status":"0","recid":"2782","relation_version_is_last":true,"title":["漏斗状根管に対するガラス繊維強化樹脂ポストを応用した支台築造"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T14:45:42.891422+00:00"}
