How does the 3M ESPE Lava Chairside Oral Scanner C.O.S. obtain a digital impression?

The Lava C.O.S. intraoral scanning wand is a video camera with a single primary lens that captures 20, three-dimensional images per second. The wand cable is connected to a cart that houses the CPU, which displays the data on a touch screen monitor. The touch screen is also used to manipulate the virtual model and interact with the system software to enter patient information and information relevant to the preparation (THE DENTAL ADVISOR Clinical Case Report, No. 10, April 2009).
