The Multi Strand wire size and close up pictures.  Dentsply Wildcat wire used here.

Anomalies are removed from the palatal / lingual surfaces of the teeth using an Ash 5 / 9 or similar.

The initial multi strand wire bend is made in the centre and further bends progress around the arch of the teeth. The Multi Strand wire should fit passively around the arch, contacting the palatal / lingual surfaces of the teeth.

The completed upper 2 / 2 and lower 3 / 3 Multi Strand wire may be finished by turning the wire on itself as shown and held in place with a small amount of wax prior to sending to the clinician / clinic.
