  • 2 x 2 area of the labial bow is covered in acrylic that is formed to the facial surfaces of the teeth

Suggested Materials:

  • Wire: Chromium Cobalt wire


  • Laser welded (removes the solder)
  • Solder: Silver Solder (Cadmium Free)
Appliance Fabrication Standards:

  • Labial bow is formed from 3 x 3
  • The adjustment loops begin just distal to the mid point on the facial of the cuspid
  • The loop ends at the interproximal of the cuspid and the first bicuspid
  • The wire is in intimate contact with the teeth in the interproximal area as it crosses the occlusion
  • The lingual wire is formed about 1mm off the tissue of the tissue to provide clearance for acrylic
  • The acrylic is trimmed to conform closely to the teeth including theinterproximal areas.
