An orthodontic applicance for preventing unwanted rotation of a tooth during its translational movement along a main guide-wire. The appliance is adapted to be held by at least one bracket affixed to a tooth. The appliance includes a main spring assembly for causing, when activated, translational movement of a tooth along the main guide-wire to reduce space between the tooth and another tooth. An auxiliary spring assembly, which is separate and spaced from the main spring assembly, includes a spring and a mesial leg extending from the spring. The auxiliary spring assembly is used to substantially prevent unwanted rotation of the tooth being moved in a lateral direction. Orthodontic wire, which includes an anchoring end, interconnects the auxiliary spring assembly and the main spring assembly. In the preferred embodiment, the mesial leg and spring are connected to a side of the bracket while the anchoring end is connected to another tooth other than the tooth having the bracket to which the auxiliary spring assembly is connected.

An orthodontic system for preventing unwanted rotation of a tooth during its translational movement in reducing a space between teeth, comprising: a first bracket having first and second slots and adapted to be affixed to a first tooth; a second bracket having at least a first slot and adapted to be affixed to a second tooth; a main guide wire being received by said first slot of said first and second bracket and extending between the first and second teeth, said guide wire inhibiting movement of the first tooth out of an occlusal plane; and an orthodontic assembly operating independently or any guide wire including said main guide wire for substantially reducing unwanted rotation of the first tooth during its translation movement, comprising: said spring means for causing, when activated, a translational movement of the first tooth in a direction along said main guide wire to reduce the space between the first tooth and another tooth, and orthodontic wire means operatively associated with said main spring means, said wire means including an anchoring end connected to one of the second tooth and another tooth and an anterior end section operatively connected to said second slot of said first bracket, wherein said anterior end section is constructed and arranged to adjustably reduce rotation of the first tooth by applying a countermoment to offset a moment created during its translational movement.
