A method of orthodontics for correcting malocclusions of a patient with an orthodontic appliance, the method comprising the steps of:

• manufacturing a set of orthodontic brackets and an orthodontic archwire specifically configured for placement on, and correcting malocclusions of, the teeth of persons of a given ethnic race;
• and
• determining the ethnic race of the patient, and, in response to a determination that the patient is of the given ethnic race:
• selecting the brackets for placement on the teeth of the patient, and
• selecting the archwire for attachment to the brackets.

A set of orthodontic brackets for treating patients of a given ethnic race, the brackets being manufactured by a process comprising the steps of:

• designing a plurality of orthodontic brackets, each having a base portion configured and adapted for attachment to a particular tooth of persons of a given ethnic race, and each having an archwire support portion fixed to the base portion;
• designing a groove for receiving an archwire in each archwire support portion, the groove having a depth and an angulation specifically selected to correct malocclusions of the teeth of persons of the given ethnic race;
• and
• manufacturing each of the designed brackets having the respective designed groove therein.
