In some patients with dental absences, the presence of the underlying tooth-less wire may hurt.

An arch wire is provided with one or more sleeves, each of which is a close fit onthe wire and in turn fits closely into the bracket slot in which it is inserted.

Thewire/sleeve combination and the bracket cooperate to produce the desired rotation andtipping of the tooth while, if required, the sleeve/bracket combination can slide freelyalong the wire.

This permits the use of very light moving forces and the use of a wire ofuniform cross-section along its length while permitting changes of the wire cross-sectionfor each and any bracket to provide the desired orthodontic action.

Preferably the wireand sleeve cross-sections cooperate to hold the sleeve against rotation about a mesial-distal axis.

The ends of the sleeve may be splayed to limit its endwise movement in thebracket slot.A sleeve may extend over more than one bracket.

The sleeve may be acontinuous tube, or it may be slit mesially-distally along its lingual face that is within theslot.
