Like glaciers and tectonic plates, teeth are slowly yet surely on the move as they attempt to turn their host’s mouth into frozen tundra and then rip it apart like a bite-size Pangaea. Defeat devious teeth with today’s Groupon: for $2,899, you get a complete Invisalign treatment (up to a $6,350 value) at Steven Donia, DDS, in Encino. This treatment includes up to 39 aligners; patients requiring longer treatment will be subject to an additional charge. This deal does not include Vivera Retainers, which are strongly recommended to ensure long-lasting results.

Steven Donia, DDS has been named an Invisalign Premier Preferred Provider and was featured on Extreme Makeover in 2006. Dr. Donia crafts camera-ready grills using a combination of highly advanced, 3-D computer graphics, and the spells of old-fashioned orthodontia. The Invisalign process eschews cumbersome braces for clear, removable aligners that are virtually invisible to the unclothed eye. An initial appointment includes an exam, x-rays and digital impressions by a sophisticated Cadent iTero machine, which snaps detailed, precise 3-D images of mouth terrains without the discomfort of traditional dental impressions. The exam paves the way for a flurry of calibrated teeth sheaths that are designed to slowly shift walnut crackers into perfect alignment. View some Invisalign FAQs here.

Depending on the client’s teeth, as few as 12 or as many as 48 separate aligners will need to be worn during a period of 6–15 months, before the straightening effect finally self-actuates in a sudden burst of pink smoke and slobber. Aligners are swapped out at included follow-up visits every six to eight weeks, and should only be removed when eating, brushing, flossing, or modeling a finely clenched jaw. Inquisitive clients can view Dr. Donia's online videos, which feature patient testimonials and educational clips.
