Which device on the palate applies gentle force to move teeth, often used to open spaces?

• A. Z spring
• B. Buccal tube
• C. Palatal finger spring
• D. Band removers

Answer: (C)

The idea here is using a small appliance that sits on the palate to guide tooth movement with light, continuous pressure. The palatal finger spring is designed exactly for this: a curved spring attached to the palatal area that exerts a gentle force on a tooth (or group of teeth) to move them and create space. Because it is anchored to the palate, it delivers controlled forces without needing bulky labial hardware, making it especially useful for opening spaces between teeth gradually and safely. Other devices don’t fit this scenario as neatly. A Z spring works between teeth to alter spacing, not from the palate. A buccal tube is a component attached to a molar to guide the archwire, not a palatal appliance that applies a direct moving force. Band removers are simply tools to take bands off bands, not devices that move teeth.
