Study Investigating Tooth Movements With Conventional and Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) Supported Fixed Appliances

NCT00871091 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 32

Summary

In orthodontics, conventional fixed appliances, usually consisting of prefabricated components, require step-by-step adjustment in order to move teeth in the planned direction.

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.
