This is an alternative method that treats selective orthodontic problems, without the use of braces. The patient is wearing throughout the treatment a series of clear matrices, which are fabricated individually for him, at different stages. These transparent matrices move the teeth gradually and they don't bother the patient, since they are invisible.
The advantages except from aesthetics are: comfort for the patient, easily achieved hygiene- since the patient can remove the appliance and brush freely. Finally, the patient can see the final result of this treatment beforehand, in a 3-Dimensional display. The major disadvantage of this technique is its cost.
