Dr. Robert A. Goshgarian introduced this arch in 1972. It crosses the palate joining as one unit both first molars;
it is effective as a moderate anchorage appliance forming an anchorage unit that resists mesial molar movement and mesial rotational lingual root tendency.
It is one of the most simple moderate anchorage appliances to make and the most used by the majority of
orthodontists.
We must take an impression with bands adapted on the first upper molars in order to fabricate one, then we pour
plaster in the impression with the bands placed in it; then we can proceed to bend the 0.036" stainless steel wire and
form the trans palatine arch, leaving a 1 or 2 mm separation between the wire and the palatine mucosa.
The trans palatine arch can be fixed, soldered to the first molar bands or directly bonded on the palatine aspect of
the molar. It can also be removable being inserted in lingual sheaths soldered on to the molar band itself.
