Modified Transpalatal Arch (m-TPA) for Vertical Control and Anchorage.
Transpalatal arch (TPA) is commonly used, but it has some limitations; like, it can be used as an anchorage appliance in extraction cases with minimal to moderate anchorage requirement, but, for maximum anchorage cases TPA needs to be supported by extraoral traction. In cases where expansion greater than 1-2 mm is required, other expansion appliances seem to be more efficient. To overcome the drawbacks of TPA we designed modified transpalatal arch (m-TPA) for various purpose.
