These metal implants are surrounded by connective tissue in the alveolar bone. Recently, a variety of biocompatible ceramic implants have been apllied to endossesous implants in the expectation of tighter bonding. Hydroxyapatite ceramic implants are anchored to the bone without the exsistence of the connective tissue. The brittle characteristic of hydroxyapatite ceramics, however, makes it difficult to shape the blade-type implant which offers a wide area of contact with the bone. A blade-type implant of titanium coated by hydroxyapatite, designed by M. Ito and K. Suzuki in 1981, overcame this difficulty. Preliminary experiments showed that the hydroxyapatite coated implant could be tightly anchored to the mandibular bone of test monkeys. In the present study, more detailed architecture of the tissue-implant interface was observed by light microscopy and compared implants coated with various mixtures of almina. In addition, the calcified appearance of the surrounding bone was investigated by microradiography and X-ray microanalysis. The results were as follows: 1) In the case of a pure aluminina-coated implant, the ingrown bone as well as thin fibrous connective tissues surrounded the implant within 6 months after insertion. 2) In the case where a pure hydroxyapatite coated implant was inserted for 6 months, the trabecular bone grew close to, or in contact with the coated surface of the implant. After 12 months, the implant was connected directly to the remodeled bone, without any soft tissues. 3) By increasing of mixture percentage of hydroxyapatite, fibrous connective tissue　between the implant and the bone, which was marked in a pure alumina-coated implant, became thinner. The result of 80% hydroxyapatite - 20% alumina coating seemed to be satisfactory, considering the necessity of alumina to increae the strength of the coating. 4) The calcified appearance of the bone surrounding the implants was shown by means of contour mapping using an X ray analyzer. More abundant calcium was observed in the ingrown bone in the case of pure hydroxyapatite-coating implant than those of pure alumina coating. In case of 80% hydroxyapatite -20% alumina coating, the distribution of calcium in the addiotional bone near the implant was the same as those of pure hydroxyapatite after 6 months. Later, the distribution of calcium became dense and there was no remarkable difference between the newly formed bone and the existing bone after12 months.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"松本歯科大学学会"}]},"item_10001_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_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-1613","subitem_source_identifier_type":"ISSN"}]},"item_10001_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":"青, 久昭"}],"nameIdentifiers":[{"nameIdentifier":"2955","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"青, 久昭"}],"nameIdentifiers":[{"nameIdentifier":"2956","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":"2016-03-04"}],"displaytype":"detail","filename":"matsumoto_shigaku_14-01-02.pdf","filesize":[{"value":"6.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://mdu.repo.nii.ac.jp/record/2460/files/matsumoto_shigaku_14-01-02.pdf"},"version_id":"e8625c41-e7a8-4fad-9987-7c030ca1317f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"implant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"hydroxyapatite coated","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"monkey","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"histology","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ヒドロキシアパタイトおよびアルミナ溶射インプラント周囲組織についての組織学的観察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ヒドロキシアパタイトおよびアルミナ溶射インプラント周囲組織についての組織学的観察"}]},"item_type_id":"10001","owner":"3","path":["78"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-03-04"},"publish_date":"2016-03-04","publish_status":"0","recid":"2460","relation_version_is_last":true,"title":["ヒドロキシアパタイトおよびアルミナ溶射インプラント周囲組織についての組織学的観察"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:05:59.413190+00:00"}
