Forget the gunmetal-gray strapping -- it's not the only way to get straight teeth. That's essentially the marketing pitch behind a new type of orthodontic device that promises a straight smile while being easy on the eyes.

Align Technology, says its 3D computer imaging and manufacturing systems are key to straightening adult teeth without uncomfortable metal braces. Their system, called Invisalign (www.invisalign.com), utilizes 3D scanning hardware, automatic surfacing software, 3D animation programs, and rapid manufacturing systems --powered in part by Geomagic technology --to produce customized, removable, clear plastic appliances called aligners. Combined with an orthodontist's treatment plan, these retainerlike aligners provide an innovative alternative to traditional braces.

The Invisalign process uses a series of clear, plastic molds to gradually move the teeth. The shape of the molds -- and hence the final position of the straightened teeth -- is determined by creating a three-dimensional movie of each patient's mouth. It simulates, from beginning to end, the stages the teeth will go through as they're adjusted.

The manufacturer of the system, Align Technology, Incorporated, of Sunnyvale, Calif., says the molds offer a more efficient way of straightening teeth, because at different stages in the process, only the teeth that need to be moved are moved.

You wear each set of aligners for about 2 weeks, removing them only to eat, drink, brush, and floss. As you replace each aligner with the next in the series, your teeth will move  little by little, week by week  until they have straightened to the final position we have prescribed. You'll visit us about once every 6 weeks to ensure that your treatment is progressing as planned. Total treatment time averages 9-15 months and the average number of aligners worn during treatment is between 18 and 30, but both will vary from case to case.
