Which item is designed to receive the archwire on the buccal side of a molar?

• A. Bracket removers
• B. Buccal tube
• C. Bands
• D. Palatal finger spring

Answer: (B)

In fixed orthodontic appliances, the archwire is carried along the teeth by attachments, and on the molars it is received through a buccal tube. The buccal tube is attached to the molar band on the cheek-side (buccal) surface and provides a slot or opening for the archwire to sit in, guiding it from the molar toward the front of the mouth and allowing ligation and adjustment as the treatment progresses. This setup specifically serves to receive the archwire on the buccal aspect of the molar.

Brackets removers are tools for taking brackets off teeth. Bands are the molar rings that encircle the tooth and may carry the buccal tube, but they themselves don’t designate the archwire path. Palatal finger springs act on the palatal side to move teeth and do not receive the buccal archwire.
