Disclosed are an orthodontic wire of giving orthodontic force to anterior teeth in order to correct bimaxillary protrusion, and an orthodontic system with the same. The orthodontic wire for correcting bimaxillary protrusion includes a lingual arch wire which is curved corresponding to a set of the anterior teeth so as to be fitted to a lingual side of the anterior teeth a traction wire which is provided in the lingual arch wire for connection with a traction member of giving lingual traction force and a pair of support wires which is extended backward from the lingual arch wire so as to provide the lingual arch wire with reaction to the lingual traction force. With this configuration, it is possible to prevent an inturned tooth when the bimaxillary protrusion is corrected, and it is also possible to correct aggressive protrusion without surgical operation since traction force is transmitted to an alveolar bone.本発明は、突出口矯正のために前歯部に突出矯正力を提供する突出口矯正ワイヤ及びこれを有する突出口矯正システムを開示する。上記突出口矯正ワイヤは、上記前歯部の舌側面に固定可能に、前歯部の歯列に合うように曲率形状の舌側弧線ワイヤ、舌側牽引力を提供する牽引部材の連結のために、上記舌側弧線ワイヤに備えられる牽引ワイヤ、及び上記舌側牽引力に対する反作用を上記舌側弧線ワイヤに提供するために、上記舌側弧線ワイヤから後方に延びる一対の支持ワイヤを含んで構成される。本発明によれば、突出口矯正時に内曲がりの歯の発生を防止することができ、歯茎骨に牽引力が伝えられて骨格性突出を外科的手術無しで矯正することができる。
