The disclosure relates to an orthodontic system and treatment method, including an arrangement of orthodontic brackets (100, 102, 104) against the patient's teeth (120, 150) such that the depth of the respective archwire slots (105, 115) of the brackets (100, 102, 104) generally increases from the anterior teeth (120) moving toward the posterior teeth (150). The gradual increase of the archwire slot (105, 115) in the bracket arrangement provides for finer control over the movement of the anterior teeth (120), while providing sufficient control and freedom of movement for the posterior teeth (150).
