The TPA Sagittal appliance is designed to move molars with TADs and elastic chains in a more anterior direction, to close space for extraction case, and to correct occlusion. The appliance is in a fixed position and comprised of bands around the maxillary permanent first molar teeth. This is useful when you encounter the need for space closure and molar sagitalization.
