DOS provides Downtown Detroit orthodontic treatment exclusively with Invisalign. Invisalign is the high tech, state of the art industry leader in clear plastic aligners. Your teeth are straightened with clear, comfortable aligners with Invisalign. DOS is one of the only adult centered practices in Detroit and Michigan. Located on East Fort Street in Downtown Detroit, Detroit Orthodontic Specialists (DOS), proudly serves the greater Detroit area. We have over 20 years of combined Invisalign experience.

The first name in clear aligner orthodontic treatment, Invisalign

Invisalign has set the standard for clear aligner treatment. The first, and most technologically advanced system, DOS has chosen Invisalign as their platform. Since its inception in 2000, they have led the way in innovation and R&D. Invisalign has pioneered the most advanced software, polymers, and adjuncts to allow for the most efficient and predictable results.

Actual DOS Invisalign Patient

These advances give us the tools to straighten your teeth quickly and easily. Your treatment time is often less than that of braces, and your appointments are often less than 15 minutes. Your aligners are fabricated from a quick and easy 3D scan of your teeth, no impressions. Invisalign is no more expensive than braces, and with recent advances in polymers and software, Invisalign is now available for almost everybody.

The iTero Element

DOS is the first office in the state to use the just released scanner, the Element. This state of the art scanner is faster, smaller, and more powerful than ever. A faster scan with a smaller wand means an easier scan for you, and a more precise file for the DOS doctors. Improved aligner fit ensures compete tooth control. The Element also features an Outcome Simulator. We will be able to show you what your smile might look like by using the built in simulator.
