In Ribbon Arch, how is the archwire held behind the tube?

• A. Pins hold the ribbon archwire behind the tube.
• B. Screws hold the archwire behind the tube.
• C. Elastics hold the archwire behind the tube.
• D. Clamps hold the archwire behind the tube.

Answer: (A)

In Ribbon Arch, the archwire is intended to run behind the molar tube, and it is secured in that retrograde position with pins that pass through the tube to lock the wire in place. These pins act as anchors, holding the wire behind the tube so it remains out of the vertical slot while still delivering the desired forces to the anterior segment. This simple pin-based method provides a stable, low-profile means of securing the archwire behind the tube, which aligns with the technique’s goal of guiding tooth movement without occupying the molar-tube slot. Elastics, screws, or clamps don’t provide the same retrograde attachment in this setup, so they aren’t used to hold the ribbon archwire behind the tube.
