Which component is cemented to a molar to receive the archwire on the buccal side?

• A. Bracket removers
• B. Bracket holders
• C. Z spring
• D. Buccal tube

Answer: (D)

In fixed orthodontic appliances, the archwire runs through attachments on the teeth, and the component cemented to a molar to receive the archwire on the buccal side is the buccal tube. The buccal tube is attached to the molar (often as part of a molar band) and has a slot that the archwire sits in, guiding its path along the arch and providing a stable anchor for movement. Bracket removers and bracket holders are instruments used during bonding or debonding, not parts that receive the archwire. A Z spring is an auxiliary spring used for space management, not a channel for the archwire.
