Orthodontic Assistant Practice Exam 2025 – 400 Free Practice Questions to Pass the Exam

The instrument that is not typically used for placing elastic separators is the hand scaler. A hand scaler is primarily designed for the removal of calculus and plaque from tooth surfaces, making it more suitable for periodontal procedures rather than orthodontic applications. In contrast, elastic separating pliers, ligature cutters, and band pushers are specifically designed for orthodontic tasks.

Elastic separating pliers are used to place elastic separators between teeth to create space for band placement. Ligature cutters can also assist in managing orthodontic materials used during the procedures, while the band pusher is essential for seating bands on the teeth after space has been created. Each of these tools has a specific purpose related to the placement and adjustment of orthodontic appliances, unlike the hand scaler, which is tailored towards dental hygiene and scaling purposes.
