Abstract:
Method of making a customized orthodontic bracket. A bracket receiving area is determined on a three-dimensional tooth model of a patient's tooth, and a bracket base is provided with a tooth-facing surface that is shaped according to the shape of the bracket receiving area. An outline of a bracket head is determined on the tooth model, and the bracket head is provided with a bracket head surface that is shaped according to the shape within the bracket head outline. The bracket has an outer surface with a shape corresponding to the natural shape of the patient's tooth, which helps to minimize discomfort during orthodontic treatment with the brackets.
