Often, classic impressions can now be replaced and / or supplemented by a scan of the jaws. With the scanner, the intraoral dentition situation can be transmitted very precisely within a few minutes digitally and the tooth and / or jaw misalignments can be analyzed on the computer. A major advantage of scanning is the possible contact-free transmission of the data, which is much more pleasant for many patients who suffer from an easily triggerable gag stimulus, for example, and simplifies treatment.
