The materials used in this study comprised the study models of nine patients diagnosed as skeletal ClassⅢmalocclusions at Orthodontic Clinic of Niigata University Dental Hospital. In all patients, more than five years passed since sagittal splitting ramus osteotomy had been undergone. We measured irregularity index, intercanine width, intermolar width, arch length, overjet and overbite using each model taken at first visit, finish of active treatment or more than five years after surgery. 1) In the period from first visit to finish of active treatment, crowding was improved. However, more than five years after surgery, irregularity index in the mandible tended to increases significantly. 2) Although overjet and overbite more than five years after surgery were decreasing compared with the period of first visit, there was no significant. 3) Intercaninewidth, intermolar width, and arch length did not show a significant change. In the cases having had large irregularity index at first visit, the change after treatment show a tendency to become large. As previously reported, the change in irregularity index of the maxilla after treatment was less than that of the mandible. It is reported that both overjet and overbite after surgery were maintained by dental compensation corresponding to the postoperative skeletal change. Thus, increase of irregularity index after treatment in the pretreatment study appears to be associated with the postoperative dental compensation.","subitem_description_type":"Abstract"},{"subitem_description":"本研究では、下顎枝矢状分割術により外科的矯正治療を行った骨格性下顎前突症患者における上下歯列弓の長期的な変化について調べ、検討した｡資料として、本学附属病院矯正歯科診療室において骨格性下顎前突症と診断され、下顎枝矢状分割術を施行した患者のうち術後5年以上経過し、資料の揃っている9症例の患者の研究用模型を用いた｡初診時、動的治療終了時、手術後5年以上経過時の各時期における上下顎歯列弓のirregularity index、犬歯間幅径、臼歯間幅径、歯列弓長、およびoverjet、overbiteを分析した｡上下顎前歯部の変化に関しては、初診時から治療終了時にかけて叢生は改善されていたが、術後5年以上経過時には下顎のirregularity indexが増加する傾向が見られた｡またoverjetは治療終了時に比べ術後5年以上経過時には減少していたが有意な変化はなかった｡overbiteも術後5年以上経過時には減少していたが有意な変化はなく、被蓋は維持されていた｡犬歯間幅径、臼歯間幅径、熾烈弓長は初診時、治療終了時、術後5年以上経過時を通じて有意な変化はなかった｡初診時のirregularity indexが大きい症例では治療後の変化量も大きくなる傾向がみられた｡また、上顎におけるirregularity indexの術後変化は下顎よりも小さく、これは過去の報告と一致した｡また、過去において手術後に骨格性の変化が生じ、その変化に対応した代償性の歯性の変化が生じて被蓋が維持されていたことが報告されており、今回見られたirregularity indexの増加はこの歯性の変化に対応した結果とも考えられる｡","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"151851","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kai, Koji"}]},{"nameIdentifiers":[{"nameIdentifier":"151852","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Takeyama, Masaki"}]},{"nameIdentifiers":[{"nameIdentifier":"151853","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saito, Isao"}]},{"nameIdentifiers":[{"nameIdentifier":"151854","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morita, Shuichi"}]},{"nameIdentifiers":[{"nameIdentifier":"151855","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hanada, Kooji"}]}]},"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":"甲斐, 康司"}],"nameIdentifiers":[{"nameIdentifier":"151846","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"竹山, 雅規"}],"nameIdentifiers":[{"nameIdentifier":"151847","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"斉藤, 功"}],"nameIdentifiers":[{"nameIdentifier":"151848","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森田, 修一"}],"nameIdentifiers":[{"nameIdentifier":"151849","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"花田, 晃治"}],"nameIdentifiers":[{"nameIdentifier":"151850","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_31(2)_39-44.pdf","filesize":[{"value":"740.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NS_31(2)_39-44.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/25744/files/NS_31(2)_39-44.pdf"},"version_id":"75ca43f1-6459-4643-b2f7-0f95b9543de9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sagittal splitting ramus osteotomy","subitem_subject_scheme":"Other"},{"subitem_subject":"skeletal Class III","subitem_subject_scheme":"Other"},{"subitem_subject":"postoperative change","subitem_subject_scheme":"Other"},{"subitem_subject":"model analysis","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":"下顎枝矢状分割術を施行した骨格性下顎前突症における上下顎歯列弓の長期的変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"下顎枝矢状分割術を施行した骨格性下顎前突症における上下顎歯列弓の長期的変化"},{"subitem_title":"下顎枝矢状分割術を施行した骨格性下顎前突症における上下顎歯列弓の長期的変化","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1315"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-27"},"publish_date":"2013-08-27","publish_status":"0","recid":"25744","relation_version_is_last":true,"title":["下顎枝矢状分割術を施行した骨格性下顎前突症における上下顎歯列弓の長期的変化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:55:44.991632+00:00"}
