Sequence of archwires of 2 bracket prescriptions (0.018 and 0.022 slots)

This is a general guideline of the sequence of archwires during treatment which can be modified according to the clinical situation.

( Summerized from a lecture of Dr. Zuhair Bakhsh ).

*For 0.018 x 0.025 slot brackets

Phase I (Alignment&Leveling):

1.0.014 Niti

2.0.016 Nitti

3.+/- 0.018 Niti

Phase II (Space Closure):

Two ways to do space closure in extraction cases:

A/Two steps retraction :

1st step (Canine Retraction) :

1. 16 ss

2. 16×16

3. 16×22 (high friction).

2nd step (Incisors retraction):

16×22 ss

B/ One Step retraction:

Also called “En masse” retraction in which  anterior segment (from canine to canine ) is retracted as one unit.
