Up to now, we have been using calipers to measure mandibular position, but this method does not assure accurate measurements of andibular position. We have developed a small and light electronic measuring device which can measure mandibular position through magnetic sensors. This device consists of a magnet attached on the lower jaw, a pair of sensor units set on the sides of the nose tip which are kept 40mm apart from the magnet, and a sensor set on the forehead to avoid geomagnetism. Calibration for the output from the sensor unit was made, and the resulting output curve was approximated to a straight line. We also tested several factors that could cause measurement error such as temperature sensitivity of the sensor, temperature sebsitivity and drift of the circuit, improvement of linearity of the sensor output, and the influence of head unrest and geomagnetism. When these factors were cleared, we proceeded to try it clinically. As a result, it was possible to measure mandibular position within a range of 30mm-50mm with an error margin of 3-5%. For centric occlusion and rest position, it became clear that we could measure mandibular position precisely by fixing the magnet onto the gingiva of the lower anterior incisor teeth.","subitem_description_type":"Abstract"},{"subitem_description":"咬合が崩壊した患者を治療するには、咬頭嵌合位を設定するにあたって、咬合高径を記録、診断することが不可欠である｡この測定には、従来ノギスを用いた方法によっているが、経時的に正確な測定を行うことは困難であった｡本研究では、磁気センサーを応用することにより、下顎位を二次元で経時的に測定することが可能な、小型軽量な電気的測定装置を開発し、装置の特性、および臨床的操作に際して生じる誤差要因を検討した。装置は、下顎に磁石を設置し、これより40mm離して鼻部に2個のセンサーユニットを、前頭部に補正用のセンサーを設置した。センサーユニットからの出力をキャリブレーションし、得られた出力曲線を直線近似式で補正した｡また、① センサーの温度特性、② 回路の温度特性およびドリフト、③ センサー出力の直線性の改善、⑥頭部動揺および地磁気の影響、の4項目に対しても補正を加え、センサーと磁石の間隔が30m～50mmの範囲で、3～5％内の誤差で直線性を保って測定可能となった｡健常者に対する測定では、磁石を下顎前歯歯頚部粘膜に固定することにより、咬頭嵌合位、安静位における顎間関係を、臨床に必要な精度で測定できることが明らかとなった｡","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"153115","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hirano, Hidetoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"153116","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kohno, Shoji"}]},{"nameIdentifiers":[{"nameIdentifier":"153117","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamada, Yoshiaki"}]},{"nameIdentifiers":[{"nameIdentifier":"153118","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sugimoto, Hiroshi"}]}]},"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":"平野, 秀利"}],"nameIdentifiers":[{"nameIdentifier":"153111","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河野, 正司"}],"nameIdentifiers":[{"nameIdentifier":"153112","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山田, 好秋"}],"nameIdentifiers":[{"nameIdentifier":"153113","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"杉本, 浩志"}],"nameIdentifiers":[{"nameIdentifier":"153114","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_26(1)_51-57.pdf","filesize":[{"value":"3.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NS_26(1)_51-57.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/25935/files/NS_26(1)_51-57.pdf"},"version_id":"6b70255e-1e24-4552-b956-6f4117d56e9b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"咬合高径","subitem_subject_scheme":"Other"},{"subitem_subject":"vertical dimension","subitem_subject_scheme":"Other"},{"subitem_subject":"磁気センサー","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic sensor","subitem_subject_scheme":"Other"},{"subitem_subject":"電気的下顎位測定装置","subitem_subject_scheme":"Other"},{"subitem_subject":"electric measuring device of mandibular position","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":"磁気センサーを応用した二次元下顎位測定装置の試作","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"磁気センサーを応用した二次元下顎位測定装置の試作"},{"subitem_title":"磁気センサーを応用した二次元下顎位測定装置の試作","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1326"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-21"},"publish_date":"2013-08-21","publish_status":"0","recid":"25935","relation_version_is_last":true,"title":["磁気センサーを応用した二次元下顎位測定装置の試作"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:55:51.937236+00:00"}
