An orthodontic appliance in one aspect for a maxillary second molar tooth is pre-adjusted to provide a distal offset that is in the range of about 6 degrees to about 10 degrees and a torque that is greater in a negative direction than about -15 degrees. In another aspect, an orthodontic appliance for a molar tooth has a buccal wall with a recess, and a notch is located in the recess for facilitating positioning the appliance on the tooth.
