No more goop, gagging, or discomfort. Using an iTero â„¢ scanner your dentist can take a highly accurate digital impression. The new technology completely eliminates the tray and putty impressions where the experience is comparable to stuffing a big wad of gum in your mouth. The old technique is incredibly unpleasant and frequently results in taking multiple rounds of impressions that can be rejected, broken, or misplaced. The iTero scanner ensures a more accurate impression from the start, resulting in improved treatment and a more comfortable patient experience. Digital impressions give you the ability to see your teeth instantly in 3D, improving communication during the consultation and treatment process.
