Numeric simulation of long-term tooth movement was performed in some studies; however, neither the play between the brackets and archwire nor the interproximal contact forces were considered. The objectives of this study were to simulate longterm orthodontic tooth movement with the edgewise appliance by incorporating those contact conditions into the finite element model and to determine the force system when the space is closed with sliding mechanics. Methods: We constructed a 3-dimensional model of maxillary dentition with 0.022-in brackets and 0.019 × 0.025-in archwire. Forces of 100 cN simulating sliding mechanics were applied. The simulation was\naccomplished on the assumption that bone remodeling correlates with the initial tooth displacement. Results: This method could successfully represent the changes in the moment-to-force ratio: the tooth movement\npattern during space closure. Conclusions: We developed a novel method that could simulate the long-term orthodontic tooth movement and accurately determine the force system in the course of time by incorporating contact boundary conditions into finite element analysis. It was also suggested that friction is progressively increased during space closure in sliding mechanics.","subitem_description_type":"Abstract"}]},"item_5_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"長崎大学学位論文 学位記番号:博(医歯薬)甲第978号 学位授与年月日:平成29年6月7日","subitem_description_type":"Other"},{"subitem_description":"Author: Ryo Hamanaka, Satoshi Yamaoka, Tuan Nguyen Anh, Jun-ya Tominaga, Yoshiyuki Koga, Noriaki Yoshida","subitem_description_type":"Other"},{"subitem_description":"Citation: American Journal of Orthodontics and Dentofacial Orthopedics, 152(5), pp.601-612; 2017","subitem_description_type":"Other"},{"subitem_description":"出版時論題変更","subitem_description_type":"Other"}]},"item_5_description_69":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Nagasaki University (長崎大学), 博士(歯学) (2017-06-07)","subitem_description_type":"Other"}]},"item_5_dissertation_number_65":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲医歯薬第978号"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"115893","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hamanaka, Ryo"}]}]},"item_5_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Inc."}]},"item_5_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.ajodo.2017.03.021","subitem_relation_type_select":"DOI"}}]},"item_5_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://hdl.handle.net/10069/37611","subitem_relation_type_select":"HDL"}}]},"item_5_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2017.
