US Patent 9149344 Customized wire device for orthodontic alignment

The appliance of the present invention is a customized wire device for orthodontic alignment of the mal-aligned teeth. The final position and orientation of the brackets are assessed by simulating the desired aligned stage. Once the final position and orientation of the brackets is known from the simulated aligned stage, this bracket position and orientation is preserved by passing a wire passively through these brackets at the desired aligned stage. This passive wire essentially forms a template of final aligned stage; when securely engaged in the brackets on the mal-aligned stage this wire needs to be deflected and generates forces that align the teeth to its designed aligned stage due to elastic recoil of the wire.
