A novel orthodontic apparatus is disclosed. The novel apparatus can be referred as a rectangular-retained arch (RRA). Examples of RRA can be used for stabilizing a new configuration of teeth so that the teeth do not move to an incorrect position. An example of RRA can have a shape of arch that is made of a single piece of material. Some embodiments of RRA can have a plurality of holes along the RRA.

An orthodontic appliance is rigid to avoid significant flexing due to therapeutic magnetic forces. The orthodontic appliance is magnetically mountable on the lingual or palatal side of teeth of a patient. Magnetic or magnetizable targets are mounted only on the lingual or palatal side of the patient's teeth. Orthodontic components are obscured from view behind the patient's teeth. Orthodontic correction is provided with improved esthetics. Magnets and/or targets can be of custom, designed or selected shapes, including non-planar shapes, to provide a desired force vector.

A method for producing a shape memory band of an orthodontic appliance. The shape memory band is one piece, has a cross section that can vary according to the longitudinal position of said cross section, and includes a bonding zone configured so as to exhibit a shape substantially identical to that of a tooth. The method includes: determining an orthodontic treatment suitable for treating the teeth, determining a set of forces to be exerted locally on the teeth in order to obtain the orthodontic treatment and the shape of the surface of the teeth to which bonding zones of the shape memory band are to be bonded, and producing the shape memory band. The local cross section of the shape memory band is determined according to the forces and in such a way as to define bonding zones substantially identical to the surfaces of the teeth.
