Material and Methods: Eighteen rabbits were included in the experiment. A trap-door technique was applied at the test sites, and the bony window was elevated inward (inward window;\nIW) together with the sinus mucosa. At the control sites, the bony window was removed before the elevation of the sinus mucosa. The elevated space was filled with deproteinized bovine bone mineral (DBBM) and both access windows were covered with a collagen membrane. Histometric measurements were performed subjacent the sinus mucosa after 2, 4, and 8 weeks of healing. Results: Very few sinuses presented small percentages of new bone in close contact with the sinus mucosa in the various period examined. The presence of bone in the neighbor areas might have influenced bone formation close to the sinus mucosa. The inward displaced bone window supported bone formation\nclose to the sinus mucosa only in the earliest period of healing, while the bone walls increased their influence over time. The lack of increased new bone percentage over time in the most central regions of the elevated sinus mucosa do not support the hypothesis that the sinus mucosa may express its potential in bone formation. It can be speculated that the new bone found in the intermediate and middle regions of the control sites in the earliest period of healing might be due to residual of bone from the osteotomy. Conclusions: Very small amounts of new bone were found subjacent to the sinus mucosa, mostly formed from the bone walls, the inward displaced bone window or from possible\nbone residues from the osteotomy procedures. The lack of increased new bone percentage over time in the most central regions of the elevated sinus mucosa indicates that the contribution to bone formation provided by the sinus mucosa is limited.","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":"乙第1653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/10.3390/ma15228077","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"Materials. 2022, 15(22), p. 8077."}]}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 淑婷","creatorNameLang":"ja"},{"creatorName":"リン, シュクテイ","creatorNameLang":"ja-Kana"},{"creatorName":"Lim, Su Tien","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-09-11"}],"filename":"otu_1653_ab.pdf","filesize":[{"value":"186 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/2000002/files/otu_1653_ab.pdf"},"version_id":"2c728843-3ab0-42ad-93ba-b072d7e41f93"}]},"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":"sinusmucosa","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sinus floor elevation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"collagenmembrane","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"trap-door","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"histology","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mesenchymal stem cells","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"periosteum","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":"Contribution to Bone Formation of the Schneiderian Membrane after Sinus Augmentation: A Histological Study in Rabbits","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Contribution to Bone Formation of the Schneiderian Membrane after Sinus Augmentation: A Histological Study in Rabbits","subitem_title_language":"en"},{"subitem_title":"サイナスオーグメンテーション後の骨形成にシュナイダー膜が与える影響： ウサギを用いた組織学的研究","subitem_title_language":"ja"}]},"item_type_id":"10006","owner":"18","path":["64"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-09-11"},"publish_date":"2023-09-11","publish_status":"0","recid":"2000002","relation_version_is_last":true,"title":["Contribution to Bone Formation of the Schneiderian Membrane after Sinus Augmentation: A Histological Study in Rabbits"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-10-16T05:53:06.648189+00:00"}
