Quad Helix
Four-helix wire framework soldered to molar bands or fitted into lingual sheaths for adjustment.
3D bands available
Printed bands. Same appliance.
Send a scan instead of impressions and the bands are laser sintered to fit from the file, with the rest of the appliance built as usual. No separators, no band-fitting appointment, and the bands seat first time.
