TYPES OF TORQUEING AUXILIARY

  • The lingual torquing effect is on account of two factors:
  •          1. Vertical plane changes to horizontal.
  •          2. Smaller circle opens to large.
  •                    Both these effects force the tips of the spurs to press in a lingual direction against the gingival portion of the crown. Reciprocally, the inter – spur spans of the auxiliary tend to lift away in a labial direction. Thus a force couple is created. The labial forces are resisted by the bracket slots and the base archwire to which auxiliary is tied this accentuates the action of root  lingual moving force.
  • Indicated when the upper lateral incisors were blocked out  palatally before treatment. Their root apices must be torqued labially to reduce the tendency for the crowns to relapse lingually.
  •     Lever arms on laterals pass incisaly for labial root torque.
