It gives absolute anchorage to molars. In addition, it is possible to prevent side effects of the first molar and expand dental arch to unilateral side, which is considered to be difficult using conventional auxiliary devices.\n\nCase 1 : The patient was a 25-years-old Japanese woman. Her chief complaint was upper teeth protrusion. The degree of overjet was 11.3 mm. Mandibular left second premolar was positioned lingually due to crowding. Lateral cephalometric analysis showed a skeletal Class II jaw relationship. Maxillary both first premolars and mandibular left second premolar were extracted. Lingual orthodontic treatment was applied using mid-palatal miniscrews and the first molar fixed type PLAS. Absolute anchorage of the maxillary both first molars were obtained and proper overjet was achieved.\n\nCase 2 : The patient was a 20-years-old Japanese woman. Her chief complaint was crowding of upper teeth. The left molars showed crossbite, and the maxillary left lateral incisor was positioned lingually. The inter-canine Class II relationship was observed. Four first premolars were extracted. Lingual orthodontic treatment was applied using mid-palatal miniscrews and the first molar fixed type PLAS. By activating the left arm of the PLAS to the buccal side, the crossbite of the left molars were corrected."},{"@language":"ja","@value":"歯科矯正用アンカースクリューを用いることにより，これまで難しいとされていた歯の移動を行うことができる一方，歯列外から矯正力が加わるため，様々なサイドエフェクトが生じる．大臼歯固定型Palatal Lever Arm System（PLAS）は，口蓋正中部に植立したアンカースクリューからPLASを介して第一大臼歯を固定することで，臼歯部の絶対固定を得られる．また，第一大臼歯のサイドエフェクトの防止や片側側方拡大など，従来の補助的装置では困難とされる歯の移動が可能である．\n\n症例1 ： 25歳女性．上顎前突を主訴に来院した．overjetは11.3mmと大きく，skeletal Class IIを示した．下顎左側第二小臼歯はspace不足により舌側転位していた．上顎両側第一小臼歯，および下顎左側第二小臼歯を抜去し，リンガルマルチブラケット装置および大臼歯固定型PLASを用いて治療を行った．上顎第一大臼歯の絶対固定が得られ，適正なoverjetを獲得することができた．\n\n症例2 ： 20歳の女性．叢生を主訴に来院した．左側臼歯部は交叉咬合を呈し，上顎左側側切歯が舌側転位していた．犬歯はII級関係で，小臼歯部は1歯対1歯の咬合関係を呈していた．上下顎両側第一小臼歯を抜去し，リンガルマルチブラケット装置および大臼歯固定型PLASを用いて治療を行った．上顎第一大臼歯の絶対固定が得られ，またPLASの左側アームを頬側に活性化することにより，左側臼歯部の交叉咬合を解消することができた．"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410845713071825152","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000402793663"}],"foaf:name":[{"@language":"en","@value":"Nakamura Yoshiki"},{"@language":"ja","@value":"中村 芳樹"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"鶴見大学歯学部歯科矯正学講座"},{"@language":"en","@value":"Department of Orthodontics, Tsurumi University School of Dental Medicine"}]},{"@id":"https://cir.nii.ac.jp/crid/1410845713071825153","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000402793661"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/stunedge59"}],"foaf:name":[{"@language":"en","@value":"Miyamoto Yutaka"},{"@language":"ja","@value":"宮本 豊"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"鶴見大学歯学部歯科矯正学講座"},{"@language":"en","@value":"Department of Orthodontics, Tsurumi University School of Dental Medicine"}]},{"@id":"https://cir.nii.ac.jp/crid/1420564276183832704","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"30333826"},{"@type":"NRID","@value":"1000030333826"},{"@type":"NRID","@value":"9000261009029"},{"@type":"NRID","@value":"9000304609789"},{"@type":"NRID","@value":"9000402793662"},{"@type":"NRID","@value":"9000303723429"},{"@type":"NRID","@value":"9000413546295"},{"@type":"NRID","@value":"9000305617292"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0055343"}],"foaf:name":[{"@language":"en","@value":"Kanzaki Hiroyuki"},{"@language":"ja","@value":"菅崎 弘幸"}],"jpcoar:affiliationName":[{"@language":"ja","@value":"鶴見大学歯学部歯科矯正学講座"},{"@language":"en","@value":"Department of Orthodontics, Tsurumi University School of Dental Medicine"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"18836216"},{"@type":"EISSN","@value":"1884538X"}],"prism:publicationName":[{"@language":"en","@value":"Journal of the Japan Lingual Orthodontic Association"},{"@language":"ja","@value":"日本舌側矯正歯科学会会誌"},{"@language":"en","@value":"JLOA"},{"@language":"en","@value":"JJLOA"},{"@language":"ja","@value":"日本舌側矯正歯科学会会誌"},{"@language":"ja","@value":"舌側矯正"},{"@language":"ja","@value":"日本舌側矯正歯科学会"},{"@language":"en","@value":"Jouenal of the Japan Lingual Orthodontic Association"}],"dc:publisher":[{"@language":"en","@value":"Japan Lingual Orthodontic Association"},{"@language":"ja","@value":"日本舌側矯正歯科学会"}],"prism:publicationDate":"2018","prism:volume":"2018","prism:number":"28","prism:startingPage":"6","prism:endingPage":"22"},"url":[{"@id":"https://search.jamas.or.jp/link/ui/2019082977"}],"availableAt":"2018","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=PLAS","dc:title":"PLAS"},{"@id":"https://cir.nii.ac.jp/all?q=%E6%AD%AF%E7%A7%91%E7%9F%AF%E6%AD%A3%E7%94%A8%E3%82%A2%E3%83%B3%E3%82%AB%E3%83%BC%E3%82%B9%E3%82%AF%E3%83%AA%E3%83%A5%E3%83%BC","dc:title":"歯科矯正用アンカースクリュー"}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2007235295"},{"@type":"CIA","@value":"130007658199"}]}
