Orthodontic Assistant Practice Exam

What is an accurate statement about the placement of archwires?

1. Each wire can be placed randomly

2. They should only be placed in the lower arch

3. Placement should begin at the molars

4. They are placed sequentially without extra instrument use

The correct answer is: Placement should begin at the molars

Placement should begin at the molars is the correct statement regarding archwire placement. This approach is fundamental in orthodontic treatment because the molars serve as key anchorage points for the archwire. Starting at the molars ensures proper alignment of the wire within the bracket system, allowing for effective force distribution along the dental arch. By initiating placement at the molars, the assistant can ensure that the wire is secured correctly through all brackets as it extends toward the anterior teeth. Proper placement here also helps avoid potential damage to the brackets and ensures a smoother adjustment process. Understanding the importance of starting with the molars provides a foundation for achieving proper alignment and movement of the teeth throughout the orthodontic treatment plan. The other options do not accurately reflect the necessary procedures for archwire placement.
