Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
May treatment be improved with customized archwires?
Study hypotheses:
* By using CAD/CAM in planning and fabrication of customized archwires, unnecessary tooth movements can be avoided and teeth can be moved on their direct path to the intended position.
* The application of CAD/CAM improves reproducibility, efficiency, and quality of orthodontic treatment.
