ABSTRACT:
The invention relates to rectangular wires and brackets for use in orthodontic treatment methods as well as to a system of treatment comprising these wires and brackets. The wires according to the invention have a smaller cross-section than conventional wires, and the cross-section of the slots of the brackets is also smaller than in conventional systems and can be so adjusted to the cross-section of the wires that the wires have sufficient play in the slots so as to allow selective three-dimensional tooth movement with biologically acceptable forces. The invention also relates to orthodontic methods using such wires and brackets.
