Abstract: Method for shaping an orthodontic wire, made of a shape-memory material, into a target geometry in order to permit precise insertion into a patient-specific orthodontic apparatus, said method having the following steps: a) creating a patient-specific target set-up of the upper jaw or lower jaw of the patient, b) placing brackets on teeth to be treated in the target set-up, c) preparing a two-dimensional image of the target set-up with brackets in a plan view, d) loading the image into a data processor, e) identifying the position of the slots of the brackets in the image, f) exporting data on the position of the slots from the data processor, g) creating a baking mold for the shape-memory wire, wherein the data are used to help generate wire-fixing portions in the baking mold that maintain the wire in areas corresponding to the slots during the baking, h) inserting the wire into the baking mold, and i) baking the wire.

Abstract: Method for producing a patient-specific bracket body (7) for a modular bracket (1) having a pad (3) and a bracket body (7), which comprises the following steps: a) providing a raw bracket body (9) having a spacer section (9d), b) establishing a first parameter for cutting through the spacer section (9d), a distance of a resulting cut surface of the spacer section (9d) from the slot (11), in order to establish a suitable height of the bracket body (7), c) establishing a second parameter for cutting through the spacer section (9d), a cutting angle to a mesio-distal axis, in order to establish a suitable torque value of the bracket body (7), d) establishing a third parameter for cutting through the spacer section (9d), a cutting angle to an occlusal-gingival axis, in order to establish a suitable rotation value of the bracket body (7), e) cutting through the spacer section (9d) according to the three established parameters, whereby a bracket body (7) is produced.

Abstract: A method for producing a patient-specific pad (3) for a modular bracket (1) having a pad (3) and a bracket body (7), which comprises the steps: P1 a) providing a pad material section, which preferably is plane, b) providing a punch having at least one punching stamp for punching out at least one raw pad (5) from the pad material section, c) punching out of at least one raw pad (5) from the pad material section by means of the punch, d) generating a patient-specific set-up, in particular made of plaster, of the teeth to be treated of an upper jaw and/or of a lower jaw of a patient, e) selecting a raw pad (5) from the raw pad library (19) for each of the patient's teeth to be treated, f) filling a gap (27) between the raw pad (5) and the corresponding tooth in the set-up using a filling material, especially of plastic, in order to produce for the pad (3) a tooth-specific glued surface (3K) allow for a form fit to the clinical tooth of the patient.
