The response of the jaw closing muscles by mechanical stimulations to the implants was studied in man as compared with the tonic periodontal jaw closing muscle reflex of the adjacent natural teeth. So the pressure thresholds of the implants and the adjacent naturalent natural examined. The findings were obtained as follows : 1. There was pressure sensibility in man with the bioactive endosseous denta limplant. But the pressure thresholds of the implants were much higher than those of the adjacent natural teeth. 2. The pressure thresholds of the implants could be measured at 1 day after implantation, and then decreased continually till 7～8 weeks after implantation, since then the pressure thresholds were held constant. 3. The pressure thresholds of the implants after the function of occlusion showed a tendency to decrease. 4. Under anesthesia at the gingival around the implants, the pressure thresholds of the implants increased in all cases, in succession with bone anesthetized, these increased still more. 5. The axial mechanical stimulation to the implants evoked not only the tonic excitatory reflex but also the tonic inhibitory reflex of the jaw closing muscles like the tonic periodontal jaw closing muscle reflex of the natural teeth. 6. And the reflex responses of the implants were occurred depending upon the state of the background activity of the jaw closing muscles. These results suggested that there also exists the feedback regulation of the jaw closing muscles by the mechanical stimulation to the implants.","subitem_description_type":"Abstract"},{"subitem_description":"理想的な人工歯根上部構造のあり方を検討する目的で､補綴処置のため20名のヒトに植立されたMgO-CaO-SiO_2-P_2O_5系結晶化ガラス(HOYA社製)およびハイドロキシアパタイト溶射チタン(スミシコン^(R)::住友化学工業社製)の生体活性型人工歯根の圧感覚閾値および人工歯根の機械的刺激による閉口筋反射について研究を行った｡顎骨と癒着する人工歯根においても圧感覚は存在した｡しかし､その閾値は近接天然歯の閾値より大きかった｡圧感覚閾値は人工歯根植立後1日で測定され､経時的に低下し植立後7～8週以降はほぼ一定であった｡咬合機能を営んだ人工歯根の圧感覚閾閲値は低下する傾向を示した｡人工歯根頸部歯肉および根端相当部の浸潤麻酔により圧感覚閾値は上昇し､人工歯根周囲に神経性の関与が考えられた｡人工歯根の機械的刺激により天然歯の緊張性歯根膜閉口筋反射に似た持続的な反射性筋活動が閉口筋に生じた｡人工歯根および近接歯刺激による閉口筋反射は刺激前の閉口筋の興奮状態(Background activity) が低い時は興奮反射が出現し､Background activity が高い時は抑制反射が出現することが多かった｡このように人工歯根からの閉口筋反射も近接天然歯と同様にBackground activity と共に変化し､人工歯根からも閉口筋へ神経性の制御機構が働くことが明らかになった。","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"153828","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamazaki, Minoru"}]},{"nameIdentifiers":[{"nameIdentifier":"153829","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kusakari, Haruka"}]},{"nameIdentifiers":[{"nameIdentifier":"153830","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shimada, Kyuhachiro"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟歯学会"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018300X","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03850153","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山崎, 稔"}],"nameIdentifiers":[{"nameIdentifier":"153825","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"草刈, 玄"}],"nameIdentifiers":[{"nameIdentifier":"153826","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島田, 久八郎"}],"nameIdentifiers":[{"nameIdentifier":"153827","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":"2019-08-19"}],"displaytype":"detail","filename":"NS_21(2)_1-17.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NS_21(2)_1-17.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/26043/files/NS_21(2)_1-17.pdf"},"version_id":"1c83eef2-fc4d-42e8-9097-841843121c9b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"dental implant","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical stimulation","subitem_subject_scheme":"Other"},{"subitem_subject":"background activity","subitem_subject_scheme":"Other"},{"subitem_subject":"periodontal jaw closing muscle reflex","subitem_subject_scheme":"Other"},{"subitem_subject":"pressure threshold and PERIOTEST value","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":"人工歯根の機械的刺激による閉口筋反射および圧感覚閾値に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"人工歯根の機械的刺激による閉口筋反射および圧感覚閾値に関する研究"},{"subitem_title":"人工歯根の機械的刺激による閉口筋反射および圧感覚閾値に関する研究","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1335"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-29"},"publish_date":"2012-07-29","publish_status":"0","recid":"26043","relation_version_is_last":true,"title":["人工歯根の機械的刺激による閉口筋反射および圧感覚閾値に関する研究"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:55:59.952833+00:00"}
