Dear Richard Lott

The company is Align Technology Inc.

You can read all about it here:
http://www.invisalign.com

They use SLA machines to produce these braces.

They have patent on this: US 5.975.893
The patent describe the process in details.
See: http://www.uspto.gov/patft/index.html

If you or anybody on the RP- mailinglist, know of
any new RP methods in dentistry, please let
me know. The use of EDM in dental restoration
as described by Stephen M. Schmitt is very
interesting.

Best regards,

Geir

I read that RP is used in the process of manufacturing Invisiline dental
braces. Does anyone have details as to what process is used?
