Buccal tubes function to what?

Buccal tubes function to what?

• A. Guide archwire through molar bands
• B. Anchor brackets
• C. Sit on incisor edges
• D. Remove bonding material

Answer: (B)

Anchorage is being tested. Buccal tubes are welded to molar bands to provide a fixed anchorage point for the orthodontic appliance. They give a receptacle with a slot for the archwire and a convenient attachment point for elastics or headgear. This stable molar anchor lets the clinician move other teeth with controlled forces while keeping the molars relatively stationary. They’re not used to seat brackets on teeth, sit on incisor edges, or remove bonding material, which is why anchorage is the best description of their function.
