When an impression of your mouth was needed in the past, this would require the use of impression putty. Not only was this putty messy, but it could also be uncomfortable and cause gagging, which could trigger anxiety in some patients. Additionally, these types of impressions were not always accurate, resulting in the need for more impressions. Today, we take impressions digitally using the Trios-3. The Trios-3 is a compact intra-oral scanner that uses optical scanning technology to capture digital impressions of your mouth, eliminating the need for impression putty. We move the scanner around in your mouth, and the optical scanning technology takes an impression of your teeth and gums, displaying the image onto a computer monitor. The impressions we take are completely accurate, meaning there is no need for additional appointments for retakes.
