Patients who suffer from crossbite often have a classic V shaped arch.

A removable appliance is custom made to fit the shape of each patient's mouth.

Slowly, over months, it is expanded using the adjustment in the appliance.

Finally, the arch becomes U shaped.

A bracket is fitted to each tooth.

A wire is then connected to each bracket.

Coloured bands secure the wire to the brackets.

Many different band colours are available.

Slowly, over several months, the wire is shortened pulling the teeth gently into line.
