Transpalatal arch

A transpalatal arch is a wire that connects the left and right upper molars across the palate. Typically, it has a U loop in the middle that allows for adjustments in width. The transpalatal arch can be adjusted to rotate a molar, push a molar backwards, or restrain both molars from moving forwards.

A transpalatal bar connects the upper left to the upper right molar. Note the bonded lingual retainer wire on the upper incisors.
