Which component is designed to connect to the molar band and receive the archwire on the buccal side?

• A. Bracket holders
• B. Bracket removers
• C. Buccal tube
• D. Alastik holders

Answer: (C)

In fixed orthodontics, the path of the main archwire from front to back must pass through a posterior attachment that is anchored to the molar band. The component designed for this purpose is the buccal tube. It is welded to the molar band and has a slot on the buccal side where the archwire sits, allowing the wire to be engaged and continue along the arch. This tube serves as a stable posterior anchor and a receiving point for the archwire as it runs through the molar region.

The other items are not built to receive the archwire from the gums to the molars: brackets hold individual teeth, bracket holders and removers are tools related to brackets, and elastics holders (alastik holders) are used to attach elastics, not to host the archwire on the molar band.
