Orthodontic Assistant Practice Exam 2025 – Complete Prep Guide

Question: 1 / 400

Why are flexible millimeter rulers often preferred in orthodontics?

They are more durable than metal rulers

They can easily contour to the shape of oral structures

Flexible millimeter rulers are preferred in orthodontics primarily because they can easily contour to the shape of oral structures. This adaptability allows orthodontic assistants and dentists to obtain precise measurements of irregular surfaces within the mouth, such as teeth, gums, and other anatomical features. The flexibility of these rulers is crucial for achieving accurate results, especially in orthodontics where precise measurement is vital for treatment planning and monitoring progress.

While durability, cost, and the ability to provide digital measurements are important factors in choosing dental tools, they are not the main reasons for the preference of flexible rulers in this specific field. The unique shapes of dental structures necessitate a measuring tool that can conform to those shapes, making flexible millimeter rulers particularly practical for orthodontic applications.
