1. a kind of computer system, for for a series of rectifier modeling in rectifiers and for being built for attached device positioningMould, the rectifier include polymeric shells, and the attached device is for making tooth be moved to the second position from first position;

  • It is describedComputer system includes processing unit, and the processing unit includes;

    For determining the device of the first position of tooth;

    For determining the device of the second position of the tooth;

    For determining the scan geometry of the tooth between the first position of the tooth and the second position of the toothDevice, the scan geometry were established by combining for tooth increment between the first position and the second position;

    For calculate motion-vector associated with the scan geometry so that the tooth from the first position be moved to thisThe device of two positions, wherein the motion-vector is configured as establishing the power system for being applied to the tooth by the rectifier, so that the toothTooth is moved to the second position from the first position;

    AndThe chamber geometry shape of the rectifier is designed based on the scan geometry between the first position and the second positionDevice, thus to the chamber geometry shape of the rectifier and this it is interdental may to treatment apply limitation friction makeLimitation.
