Abstract: An apparatus and method for orthodontic treatment is disclosed. The orthodontic apparatus comprises a bracket configured for attachment to a tooth in a set of brackets configured for attachment to a set of teeth and configured to be engaged by an archwire installed in the set of brackets to facilitate orthodontic treatment. A bracket comprises a base for attachment to the tooth and at least one slot for the archwire with a ridge and a depression and a chamfer. The ridge of the slot is configured to engage in contact with the archwire so that force from the archwire is applied by contact at the ridge to the bracket. The method of providing orthodontic treatment uses a set of brackets for a set of teeth connected by an archwire. The method comprises configuring each bracket in the set of brackets with a ridge-depression arrangement providing a ridge in a slot, attaching each bracket to a tooth and connecting the set of brackets with an archwire inserted in the slot.
