Abstract:
1. A method for producing a customized orthodontic device for treatment of a patient, the device comprising a plurality of bracket assemblies each of which comprise a bracket which is provided with at least one groove, a base configured to be placed on a face of a tooth, and an intermediate component that extends between the bracket and the base, the method comprising: obtaining a digital representation of a dentition of the patient in the corrected position; before digitally designing each bracket assembly, positioning a model straight wire archwire extending in a single plane and comprising at least one portion having a substantially continuous curvature relative to faces of a plurality of teeth in the digital representation; digitally designing each bracket assembly associated with the at least one portion by; digitally designing the base to conform to the face of the tooth to which the base is to be placed; digitally positioning the bracket relative to the model straight wire archwire such as to receive the at least one portion of the model archwire in the groove of the bracket without deformation of the substantially continuous curvature of the at least one portion of the model straight wire archwire; and after digitally designing the base and digitally positioning the bracket, digitally designing the intermediate component to extend between the bracket and the base; and producing each digitally designed bracket assembly.
