Abstract :
The transpalatal arch might be one of the most common intraoral auxiliary fixed appliances used in orthodontics in order to provide
dental anchorage.The aim of the present case report is to describe a case in which an adult patient with a tendency to class III, palatal
compression, and bilateral posterior crossbite was treated with double transpalatal bars in order to control the torque of both the
first and the second molars. Double transpalatal arches on both first and second maxillary molars are a successful appliance in order
to control the posterior sectors and improve the torsion of the molars. They allow the professional to gain overbite instead of losing
it as may happen with other techniques and avoid enlarging of Wilson curve, obtaining a more stable occlusion without the need
for extra help from bone anchorage.
