What is a defining feature of the Ribbon Arch configuration?

• A. Vertically positioned rectangular slot behind the tube, with a ribbon archwire that was 11x20 gold wire held by pins
• B. Horizontal slot 22x28 width used in Edgewise
• C. Eyelets soldered on the corners of the band for rotational control
• D. A hollow rectangular space behind each tooth

Answer: (A)

The defining feature is a vertically oriented rectangular slot behind the molar tube that accepts a ribbon-shaped archwire, typically an 11x20 gold wire, which is held in place by pins. This setup creates a distinct way of delivering light, continuous forces and allows precise control of tooth movement by using the wire’s contour while fixed behind the tube. The other options describe aspects of different bracket systems or mechanisms that aren’t characteristic of the Ribbon Arch configuration.
