Transpalatal Maintainer - Molar Rotator

The Transpalatal Arch Maintainer consists of a transverse arch wire positioned palatally, into the vault, with a midline loop.  It is soldered to the molar bands and helps to prevent mesial migration of the 1st molars during permanent tooth eruption.  The TPA can be inserted as a passive appliance or slight adjustments may be made to widen and/or rotate the molars.  Fixed/Removable attachments can be added upon request:  Select from Wilson 3-D attachments (double post and tube design), Mershons with locktite wires (single post and tube), or horizontal sheathes.
