Types of orthodontic devices

Brackets and archwires apply controlled forces to teeth, while clear aligners use a sequence of removable plastic trays. Palatal expanders widen a developing upper jaw, functional appliances influence jaw posture during growth, and retainers hold teeth after active movement.

An orthodontic assessment normally includes photographs, an examination of the bite, digital scans or impressions, and radiographs when indicated. The clinician then maps tooth roots, jaw relationships, space, and eruption before selecting an appliance and activation schedule.

Seek an orthodontic assessment for crowding, crossbite, open bite, prominent teeth, difficulty cleaning, or teeth that are not erupting normally. Contact the treating clinic promptly for a loose bracket, broken wire, cracked aligner, or appliance that injures the cheek or gum.

Ask which problem the proposed appliance is correcting, whether it is removable, how it will be cleaned, and what happens if it is not worn as instructed. Ask how retention will maintain the final tooth positions and how growth affects the plan.
