Who is responsible for adjusting arch wires on orthodontic appliances?

The responsibility for adjusting arch wires on orthodontic appliances lies with the orthodontist. This is because orthodontists are specialists who have completed additional training focused on the diagnosis, prevention, and treatment of dental and facial irregularities. Their expertise enables them to make precise adjustments to orthodontic appliances, including arch wires, ensuring that treatment progresses as planned and that the desired movement of teeth occurs safely and effectively.

While licensed dental assistants play a supportive role in orthodontic practices, their scope typically does not include making adjustments to orthodontic appliances without the orthodontist's direction or supervision. Dental hygienists, who are trained to provide preventive dental care, do not perform any adjustments on orthodontic appliances either. General dentists, while they may provide some orthodontic services, usually refer patients to specialists for more complex adjustments and treatments.
