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.

Method for manufacturing a dental expander having: - a first attachment member intended to be fixed to a first fixation tooth of a patient; - an active member rigidly connected to the first attachment member; said method having the following successive steps: a) a three-dimensional digital model of a dental arch having the fixation tooth, or "arch model", is generated, preferably by means of an optical scanner; b) the arch model and preferably a treatment to be applied to the patient are used as a basis for generating: - a three-dimensional digital model of the first attachment member, the model of the first attachment member having 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; c) the model of the first attachment member is used as a basis for manufacturing said first attachment member and/or the model of the active member is used as a basis for generating said active member, in both cases preferably by 3D printing.

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.
The invention relates to a measuring apparatus having: - a set of needles (13) consisting of a plurality of measuring needles (14), - a set of actuators consisting of a plurality of actuators (16), each actuator being configured to move a respective measuring needle between a passive position and a plurality of active positions; - a control module (20) configured to activate said actuators, each measuring needle having a sensor configured to measure a characteristic of said measuring needle or of the environment of said measuring needle.

A variable-geometry mould comprising: - a first set of needles (13) consisting of a plurality of first needles (14), - a first set of actuators consisting of a plurality of first actuators (16), each first actuator being configured to move a respective first needle between a passive position and a plurality of active positions; - a second set of needles (13') consisting of a plurality of second needles (14'), - a second set of actuators consisting of a plurality of second actuators (16'), each second actuator being configured to move a respective second needle between a passive position and a plurality of active positions; - a control module (20) configured to activate said first actuators and said second actuators so as to arrange end faces (21) of free ends of said first needles and said second needles along a first active surface, substantially reproducing a first dental surface, and along a second active surface, substantially reproducing a second dental surface, respectively, said first dental surface and second dental surface corresponding respectively to the surface of teeth of a first arch and to the surface of teeth, opposite to the first teeth, of a second arch of a patient.
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.

A method for producing a band of an orthodontic appliance according to the invention, said method comprising the following steps: a) determining an orthodontic treatment suitable for treating the teeth of a patient; b) determining a set of forces to apply locally onto said teeth to obtain said orthodontic treatment and the shape of the surface of the teeth to which bonding areas of said shape memory band need to be adhered; c) producing said shape memory band, the local cross-section of said shape memory band, and in particular the local cross-section of inter-attachment sections of said shape-memory band, being determined according to said forces and in such a way as to define bonding areas substantially identical to the surfaces of said teeth to which they need to be adhered.
The invention relates to a method for producing an orthodontic appliance intended to be secured to a user's teeth in order to carry out an orthodontic treatment, the appliance having an element, said method having the following steps: a) gathering information relating to said set of teeth; b) using said information to determine at least first and second stable shapes of said element towards which the element should tend to deform during first and second periods of the treatment, respectively, the stable shape towards which said element tends to deform at a given time being called "operational"; c) producing and programming said element in such a way that the application of a stimulus during the first period of the treatment renders said second stable shape operational method in which, in step c), a material that is retractable or expansible under the effect of the stimulus is incorporated into the element.
