SM210 Transpalatal
Appliance Purpose / Function:
The Transpalalatal Arch is an excellent choice to maintain space aquired after expansion or distalization. It may be designed as a straight wire crossing the palate between the molars or with an omega loop (coffin spring) which will allow adjustment and can provide some molar rotation.
Appliance Components:
- Bands on left and right side of the arch
- .036 wire 1mm-2mm off of the palate
Suggested Materials:
- Wire: Chromium Cobalt wire
- Solder: Silver Solder (Cadmium Free)
Options:
- Laser welded (removes the solder)
Appliance Fabrication Standards:
- The transpalatal wire is a uniform1 to 1.5mm from the tissue across the palate.
- The coffin spring of the transpalatal arch is bent with the opening in the coffin spring facing mesial unless otherwise requested
Fabrication Notes:
If the appliance is fabricated with the opening in the coffin spring facing distal, pressure applied on the wire by the tongue will tip the molars forward.
If the appliance is fabricated with the opening in the coffin spring facing distal, pressure applied on the wire by the tongue will tip the molars forward.
