Standard stainless steel S.W.A. brackets.
The 'Straight-wire appliance' (or
S.W.A.) is the most commonly used form of fixed appliance today.
The bracket for each tooth has a unique prescription built into
it which allows very precise movements to be achieved relatively
simply so that each tooth can be accurately moved into it's correct
position.
Stainless steel brackets and bands are temporarily cemented
onto the teeth, and wires, springs or elastics are used to
exert forces on teeth to gently guide them into position. |

Coloured ligatures may be used to hold the wires in place. These are
considered by many as a fashion accessory.
Wires, springs, elastics and ligatures are usually adjusted every
6 weeks to ensure continual movement.
Stainless Steel braces are used for NHS (for the under 18s only)
and private treatments
