Types of Digital Impression Technology. There are two types of digital impression technology currently available for dentists to use. One type captures the images as digital photographs, providing dentists and dental laboratories with a series of images; the other type captures images as digital video. The images can be captured using lasers or digital scanning.
An impression is taken of your teeth and the bite recorded. The dentist tells the technician which tooth (or teeth) are going to be extracted. The technician grinds these off the model of your teeth to simulate the extraction and makes the denture in the normal way.
