Abstract: A method of preparing an orthodontic bracket. Such an orthodontic bracket has a bracket bonding pad and a bracket body with a bracket slot. The method has steps of providing a precursor of an orthodontic bracket into a machine for modifying the shape of the orthodontic bracket precursor. The orthodontic bracket precursor has an alignment structure of a pre-determined geometry. Further the alignment structure and the bracket slot are spatially arranged relative to each other at a pre-determined distance and orientation. The method further has the steps of aligning the orthodontic bracket precursor based on the alignment structure and embedding the orthodontic bracket precursor at least partially in a liquid. The liquid is cause to solidify and thereby the orthodontic bracket precursor is retained in position. The so retained orthodontic bracket precursor is changed in shape. The invention helps finishing pre-finished individually shaped orthodontic bracket precursors in a relatively accurate and controlled manner.

Abstract: A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.
