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. 16×16 ss ( less friction and smooth sliding).

2. 16×22 ss (high friction but better control).

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.

1. 16×22 ss

2. 17.25 ss

Phase III (Finishing & Detailing) :

1.16×22 SS /TMA

2. 17×25  SS/TMA

**For 0.022 x 0.028 slot brackets

Phase I (Alignment&Leveling):

1.0.014 Niti

2.0.016 Nitti

3.0.018 Niti

4.17×25 Niti

5.19×25 Niti

Phase II (Space Closure):

Two ways to do space closure in extraction cases:

A/Two steps retraction :

1st step (Canine Retraction) :

18 ss

2nd step (Incisors retraction):

19×25 ss

B/ One Step retraction:

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

1. 17×25 ss

2. 19.25 ss

Phase III (Finishing & Detailing) :

1.17×25 SS /TMA

2. 18×25  SS/TMA

3. 19×25 ss/TMA

  1. please , the wire 19.25 SS for incisor retraction?
    is it rectangular in all segments or 19.25SS rectangular in anterior segment and round in posterior segment?
    thank you.

    1. if you use 18 slot brackets , use 16×16 ss for canine retraction and 16×22 ss wires for incisors retraction for better incisor torque control.
      if you use 22 slot brackets , use 18 ss for canine retraction and 17×25 ss or 18×25 ss wires for incisors retraction.

      19 is the height of the wire , 25 is the width ( depth ).
