FIELD: medicine. ^ SUBSTANCE: implementation of a system involves a computer for virtual designing of an orthodontic appliance with an integrated appliance design programme for preparing a virtual spatial representation of the orthodontic appliance, including bracket bodies and bracket substrates, and an injection-moulding machine for moulding each bracket body and bracket substrates. The system also accommodates a data processing computer comprising a computer program for computed manufacturing which gives control command to an electric-spark manufacturing system, including a virtual spatial representation of a groove in the bracket body, and also involves the electric-spark manufacturing system. The electric-spark manufacturing system can accommodate a controller integrating a control program generating control signals bearing the control commands for the electric-spark manufacturing system, and can accommodate the electric-spark manufacturing system. ^ EFFECT: disadvantages of known bracket systems and methods for making are overcome. ^ 26 cl, 27 dwg |
