One sidewall includes a camber, or curved surface, and the outer surface of the other sidewall is flat, or planar. hwire connected to the brackets; an interarch appliance for repositioning the lower dental arch relative to the upper dental arch, the interarch appliance including a coupler having an arm; and an attachment device connected to the orthodontic system, the attachment device including a body having a first section and a second section, the first section having a passage with a rectangular cross-sectional configuration for receiving the archwire, wherein the first section is substantially non-rotatable relative to the archwire in direction about the length of the archwire, wherein the second section includes an opening that pivotally receives the arm of the coupler, wherein the passage has a central axis, wherein the opening has a central axis that extends in non-parallel and non-intersecting relationship to the central axis of the passage, wherein the passage has an upper side that generally extends in the occlusal plane of the patient when the device is in use in the oral cavity, and wherein the second section generally extends along a path away from the central axis that is at a certain angle relative to the upper side, and wherein the angle lies between a gingival direction and a buccolabial direction relative to the patient's lower dental arch when the device is in use in the oral cavity. 2. An orthodontic assembly according to claim 1 wherein the opening is substantially circular. 3. An orthodontic assembly according to claim 1 wherein the central axis of the opening extends in a direction that is generally perpendicular to the central axis of the passage. 4. An orthodontic assembly according to claim 1 wherein the body has an entryway into the passage for receiving the archwire in directions laterally of the central axis of the passage, and wherein the entryway can be closed after the archwire is received in the passage. 5. An orthodontic assembly according to claim 1 wherein the angle is in the range of about 30 degrees to about 90 degrees. 6. An orthodontic assembly according to claim 1 wherein the angle is in the range of about 45 degrees to about 60 degrees. 7. An orthodontic assembly according to claim 1 wherein the first section includes a first part extending along a portion of the passage and a second part extending along another portion of the passage, wherein the first part is connected to the second part for pivotal movement toward and away from the second part, and wherein the first part and the second part present an entryway into the passage when the first part is moved away from the second part, and wherein the entryway is generally closed when the first part is moved toward the second part. 8. An orthodontic assembly according to claim 7 wherein the first section is a unitary component made of a fully annealed material that is bent past its yield point when the first part is moved toward the second part. 9. An orthodontic assembly according to claim 1 wherein the interarch appliance includes a first member and a second member, wherein the second member has a tubular configuration, and wherein the first member has a portion slidably received in the second member. 10. An orthodontic assembly according to claim 9 wherein the interarch appliance also includes a third member having a tubular configuration, wherein a portion of the second member is slidably received in the third member. 11. An orthodontic assembly according to claim 1 wherein the arm of the coupler has a generally hook-shaped configuration. 12. An orthodontic assembly comprising: an orthodontic system including a set of brackets and an elongated archwire connected to the brackets; an interarch appliance for repositioning the lower dental arch relative to the upper dental arch, the interarch appliance including a coupler having an arm; and an attachment device connected to the orthodontic system, the attachment device including a body having a first section and a second section, the first section having a passage receiving the archwire, w
