DBBM with granule dimensions of either 1 to 2 mm (large group) or 0.250 to 1.0 mm (small group) were used to randomly fill the subantral hollow spaces. Biopsy specimens of the experimental sites from six animals in each group were obtained 2, 4, and 8 weeks after the surgery.\n\nResults: The integrity of the sinus mucosa was clinically evaluated during surgery using a ×2.5 magnifying visual device. The sinus mucosa in contact with the biomaterial granules was found to be thinned compared with the pristine mucosa in all periods examined. Three hundred fifty-two thinned zones were found considering all 36 sinuses treated. Perforations of the sinus mucosa with extrusion of granules toward the sinus were observed, increasing in number over time. In the 8-week healing period, five perforations in three sinuses and eight perforations in four sinuses were found in the large and small groups, respectively. No differences were seen between the large and small groups. The differences between 2 and 8 weeks were statistically significant for the thinned mucosa width in both the large and the small groups and for the number of sinuses and perforations for the small group.\n\nConclusion: Thinning zones and perforations of the sinus mucosa were seen increasing in number over time in regions in contact with graft granules in both the large and small groups.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第949号"}]},"item_10006_relation_14":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.11607/jomi.8580","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"The International Journal of Oral & Maxillofacial Implants. 2021, 36(4), p. 660-668."}]}]},"item_10006_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2021 Quintessence Publishing Co, Inc","subitem_rights_language":"en"}]},"item_1696310207136":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三木, 通英","creatorNameLang":"ja"},{"creatorName":"ミキ, ミチヒデ","creatorNameLang":"ja-Kana"},{"creatorName":"Miki, Michihide","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-04-04"}],"filename":"kou_949.pdf","filesize":[{"value":"216.9 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","objectType":"abstract","url":"https://osaka-dent.repo.nii.ac.jp/record/357/files/kou_949.pdf"},"version_id":"e73777ae-76c2-4095-984b-074cd4c0759f"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-03-01"}],"filename":"kou_949_fulltxt.pdf","filesize":[{"value":"916 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"学位論文","objectType":"fulltext","url":"https://osaka-dent.repo.nii.ac.jp/record/357/files/kou_949_fulltxt.pdf"},"version_id":"c1eb2741-3c41-44aa-a88e-164195b3fa91"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"animal study","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bone healing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sinus floor elevation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"xeno graft","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"perforation","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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Incidence of sinus mucosa perforations during healing after sinus elevation using deproteinized bovine bone mineral as grafting material: a histologic evaluation in a rabbit model","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Incidence of sinus mucosa perforations during healing after sinus elevation using deproteinized bovine bone mineral as grafting material: a histologic evaluation in a rabbit model","subitem_title_language":"en"},{"subitem_title":"脱タンパクウシ骨ミネラルを用いた上顎洞底挙上術における術後洞粘膜穿孔の発現:ウサギを用いた組織学的評価","subitem_title_language":"ja"}]},"item_type_id":"10006","owner":"16","path":["60"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-04"},"publish_date":"2023-04-04","publish_status":"0","recid":"357","relation_version_is_last":true,"title":["Incidence of sinus mucosa perforations during healing after sinus elevation using deproteinized bovine bone mineral as grafting material: a histologic evaluation in a rabbit model"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2024-03-13T03:54:52.306403+00:00"}
