The transpalatal arch (TPA) holds the upper first molars in position, stabilising them during or after the movement of other teeth.
A transpalatal arch is a fixed appliance made of two bands on the upper first molars, joined by a wire that crosses the palate, usually with a central loop. It gives orthodontists control of the upper first molars: reinforcing anchorage, derotating or uprighting molars, maintaining transverse width after expansion and holding space for the permanent teeth. We make TPAs to your prescription for orthodontic practices across the UK.
The TPA reinforces anchorage. By connecting the upper first molars across the palate, it stabilises them and resists unwanted movement during space closure, levelling and alignment with fixed appliances. Send us a digital scan (iTero, 3Shape, Medit, Dexis or Owandy) or an impression by post, with your design requirements on the prescription.
