The present invention relates to a dental brace that is put on a corrective dental arch for cooperation with an occlusal dental arch to use, comprising: a plurality of elastic arms, extensive portions and corrective portions. Each elastic arm contacts with a lingual side or a buccal side of the corrective dental arch and not over a lowest occlusal surface of the corrective dental arch. The corrective portions are connected with the elastic arms by the extensive portions and contact with a highest occlusal surface of the corrective arch, and the height of corrective portions will over the occlusal surface. Meanwhile, the corrective portion has a corrective plane that is bitten by the occlusal dental arch for generating an occlusal force substantially vertical to the highest occlusal surface. A protruding tooth of the corrective dental arch can be corrected by the occlusal force for solving the problem of malocclusion between the corrective dental arch and the occlusal dental arch.本發明牙套配合矯正牙弓與對咬牙弓使用，並主要由複數個彈臂、延伸塊以及矯正塊所構成，該每一個彈臂接觸於矯正牙弓的內側或外側，並都不超過於矯正牙弓中最低高度位置的咬合面，而矯正塊經由延伸塊而成形於彈臂，並接觸於矯正牙弓中最高高度位置的咬合面，使得矯正塊超過於最高高度位置的咬合面，其中，矯正塊具有矯正平面，而對咬牙弓對矯正平面進行咬合以形成一近乎垂直於咬合面的咬合力，使得矯正牙弓中較凸出的牙齒能透過咬合力進行矯正以改善矯正牙弓與對咬牙弓之間咬合不正的問題。
