ABSTRACT:
Force-transmitting means serve to exert a correcting force on at least one tooth of a patient and comprise an elongated first element and at least one second element. At least one clamping sleeve resiliently clamps itself on said first element and engages said second element and has a radially inwardly tapering longitudinal slot, which is adapted to receive an implement which is operable to widen said slot so that said clamping sleeve is slidable along said first element.
