The present invention aims to provide an orthodontic appliance capable of efficiently applying vibration to teeth to be aligned and enabling a treatment to be easily and safely continued even at home. This appliance is provided with a load applying mechanism and a vibration generating actuator. The load applying mechanism is mounted on teeth to apply a load for the malocclusion correction to a specified tooth in the teeth. The vibration generating actuator includes a contact portion that is inserted into a buccal cavity containing the teeth and can come into contact with a part of the load applying mechanism corresponding to the specified tooth or the specified tooth, and applies a vibration force from the contact portion to the specified tooth or the part of the load applying mechanism.
