Orthodontic Springs: Function, Types, and Patient Guidance

Role in Tooth Movement

Springs (coil springs, cantilever springs) deliver controlled, continuous forces to specific teeth or segments. They are integrated into the archwire or attached via hooks to:

• Open or close spaces
• Upright molars
• Correct rotations
• Maintain space during alignment

Clinical Workflow

1. Orthodontist selects spring type/force based on treatment plan.
2. Activated at adjustment visits; force dissipates as teeth move.
3. Patient may feel pressure for 1–3 days; soft diet, analgesics if needed.
4. Avoid hard/sticky foods that distort springs.
5. Hygiene: brush around springs meticulously; floss threaders or water flosser.

Outcome

Springs enable precise, efficient mechanics that complement bracket-and-wire systems.
