Digital dental impression12/3/2023 ![]() If there are errors, it is quick and easy to re-scan and correct the problem before sending the final impression. It creates a positive impression when the scan is complete, and with the ability to magnify the image, it is much easier to spot errors. The digital method is much faster and more precise. If necessary, additional scans can easily be made. The result is obtained far quicker, and it is possible to analyse the results of the scan immediately, even during the same appointment. The dentist will check for errors in the negative impression, but as it is inverted, spotting errors is more difficult, and if errors are detected, the patient will have to undergo the procedure again. All of this makes it more likely that errors will occur. It involves many more steps than its digital counterpart, and utilises multiple materials. The traditional method of taking dental impressions is a delicate process, requiring a lot of skill. What is the difference between digital and traditional impressions? Once the scan is complete, the digital impression is usually send to a dental CAD/CAM system to create the restoration. Both options are safe and highly accurate.Īn intraoral wand is typically put in the patient’s mouth to conduct the scan. The procedure can either involve laser scanning, using concentrated beams of light to capture the teeth and gums in precise detail, without the need for any unpleasant material in the patient’s mouth, or d igital optical scanners, which require a special spray on the teeth to capture accurate detail. There are two types of digital dental impression – one is image-based, capturing a series of digital photographs, while the other captured a digital video. What does a digital dental impression involve? These digital impressions are highly accurate and can be completed in minutes, with minimum discomfort for the patient. Modern advances in technology mean that dentists can now create virtual impressions of the hard and soft tissues in the mouth using optical scanning devices. Traditionally, this is done by using one of a number of possible casting materials to create a negative imprint of the teeth, which can then be used to create a positive replica. A dental impression is an accurate mould of a person’s teeth.
