Abstract: Disclosed is a method for producing an orthodontic appliance for securing to a user's teeth in order to carry out an orthodontic treatment, the appliance having an element. The method includes a) gathering information relating to the user's set of teeth; b) using the information to determine at least first and second stable shapes of the element towards which the element should tend to deform during the first and second periods of treatment, respectively; and c) producing and programming the element in such a way that the application of a stimulus during the first period of the treatment renders the second stable shape operational. In certain aspects in step c), a retractable or expansible material is incorporated into the element.

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.

Abstract: Method for manufacturing a dental expander having a first attachment member intended to be fixed to a first fixation tooth of a patient and an active member rigidly connected to the first attachment member. The method includes: a) generating a three-dimensional digital model of a dental arch having the fixation tooth or “arch model”; b) using the arch model as a basis for generating: a three-dimensional digital model of the first attachment member, wherein the model of the first attachment member that has an inner surface that substantially reproduces a part of the surface of the first fixation tooth, and/or a three-dimensional digital model of the active member; and c) using the model of the first attachment member as a basis for manufacturing the first attachment member and/or using the model of the active member as a basis for generating the active member.
