The invention is a magnetic orthodontic device, which includes an orthodontic piece and a magnetic piece. Orthodontics: It includes an alveolar bone joint part and a magnetic fixing part arranged on the alveolar bone joint part, the alveolar bone joint part is used to combine with teeth or alveolar bone. Magnetic parts: installed on the magnetic fixed part. When the magnetic element of the present invention is used in conjunction with the magnetic element of another magnetic orthodontic device, the two magnetic elements can be close to or away from each other by the principle of magnetic attraction or repulsion, thereby avoiding the need to move the crown of the tooth first. Will move slowly, which can effectively reduce the treatment time of orthodontics.本發明為一種磁力牙齒矯正裝置,其包括矯正件及磁力件。矯正件:包括有齒槽骨結合部及設置於齒槽骨結合部的磁力固定部,齒槽骨結合部係用於與牙齒或齒槽骨相結合。磁力件:裝設於磁力固定部。本發明的磁力件搭配另一磁力牙齒矯正裝置的磁力件使用時,兩磁力件能藉由磁力相吸或相斥的原理而相互靠近或遠離,藉此避免需先使牙冠移動後,牙根才會緩慢地移動,能有效地減少牙齒矯正的治療時間。
