Unmet Need
A product to digitally record dental anatomy and eliminate the need for physical dental impressions. The accuracy and patient comfort of the procedure must increase, while the cost and duration must decrease by minimizing the labor involved.

Approach
Ormco’s Lythos Digital Impression System effectively harnesses the power of digital scanning to capture intraoral data with accuracy and ease of use for the orthodontist, dentists and their staff.

Product Features
The product utilizes Accordion Fringe Technology (AFI) Technology which generates 3D data in real time versus post-process stitching. The resulting digital scan is an accurate, high-definition image detailing all angulations of the tooth surface and geometry of the arch. Stereo lithography (STL) files can be sent to the orthodontic labs free of charge and allows patient data to be easily integrated with manufacturers to produce a variety of custom appliances and/or study models. ??The unit weighs less than 30 pounds for easy transport from operatory to operatory and features an easy-to-clean touch screen for flexible viewing of models on screen and when entering patient data.
