Does the 3M ESPE Lava Chairside Oral Scanner C.O.S. require application of powder to the teeth?
The Lava C.O.S. requires a thin dusting with titanium dioxide powder to facilitate scanning of the preparation and the adjacent teeth. The application of the powder is very light and in most cases barely perceptible to the eye. Once the powder is applied, the prepared arch is scanned.
