Abstract: The present invention relates to an orthodontic appliance with an orthopedic function. The orthodontic appliance includes an upper teeth aligner mounted on user's upper teeth to correct arrangement of the user's upper teeth, a lower teeth aligner mounted on user's lower teeth to correct arrangement of the user's lower teeth, and occlusal force conversion units respectively provided on the upper teeth aligner and the lower teeth aligner, and configured to interact with each other in a state in which the upper and lower teeth aligners are in contact, so as to cause the relative position of a mandible with respect to a maxilla to move to a normal position. The orthodontic appliance is freely attached to and detached from the user's teeth like conventional clear orthodontic appliances so as to be easily used, and thus simultaneously corrects teeth arrangement and performs orthopedic treatment.
