Abstract
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.
