[2025-10-02T01:15:22.506473] [PI reasoning] **Evaluating orthodontic devices**

I need to figure out which orthodontic devices work on the traction principle, specifically looking at the Ferrier double bow separator, Elliot separator, and Perry separator. The Ferrier double bow likely relies on traction, and the Elliot separator might as well. I’m wondering if the Perry separator uses wedging instead. Separators generally utilize wedging, traction, or spring mechanisms, and I want to confirm this quickly. Let’s check to clarify.

It seems the search isn't retrieving the information I expected, so I'll rely on what I know. According to Weiss principles, there are classifications involving traction separators like Ferrier's double bow and Perry's type. I remember Perry's separator being relevant in restorative dentistry for preparing proximal surfaces. Mechanical separators like Ivory and Ferrier are used to create space for matrix band insertion. They aren't orthodontic but fall under mechanical tooth separators, which include traction and wedging categories.
