Orthodontic Wire Types Explained
Orthodontic archwires include nickel titanium, stainless steel, and other alloys; learn how types and sequencing provide the force needed at each stage.
The short answer
Orthodontic archwires include nickel titanium, stainless steel, and other alloys chosen for the force and control needed at each stage. The wire sits in bracket slots or attachments and transmits a planned force to move teeth through the periodontal ligament.
How do different archwires control tooth movement?
Nickel titanium wires are flexible and can provide light continuous forces during early alignment, while stainless steel is stiffer and useful when detailed space closure or torque control is needed. Rectangular wires engage more bracket surfaces than round wires and can control tooth angulation.
How should you care for orthodontic wires and brackets?
Attend adjustments as planned, keep brackets and wires clean, and use orthodontic wax over a rubbing end while arranging advice. Do not cut or bend an archwire at home unless the orthodontic team gives specific instructions.
When does a damaged archwire need urgent review?
Contact the orthodontic team if a wire is poking, broken, displaced, or causing a persistent ulcer, or if a bracket has detached. Seek prompt care for facial swelling, severe pain, or swallowing or breathing difficulty.
What should you ask about your planned archwires?
Ask which alloy, cross-section, and sequence are planned and what each wire is meant to achieve. Ask how the wire will control rotation, root position, space closure, and the final bite.
Frequently asked questions
Why does the orthodontist change wires?
Different wire stiffnesses and shapes provide different levels of alignment, space control, and tooth-position control.
Can I replace a poking wire myself?
Do not bend or remove it without instructions; wax can protect the cheek temporarily while the orthodontic team advises you.
