3-D Virtual Dental Impressions

Posted in Dentures

What is CAD/CAM Dentistry? CAD/CAM is a 3-dimensional imaging device that allows dentists to perform a scan of the tooth for use in fabricating restorations like dentures, crowns, onlays or even braces.  One example is the Dentca denture system  that eliminates the need for dental impressions and significantly reduces the number of visits the patient needs to make to the dental office for their dentures to be fitted.

This unique piece of technology allows dentists to send the patient’s virtual dental impression directly to dental laboratories for appliance manufacturing. Some dentists also have in-office crown fabrication, which uses this virtual impression image to create a permanent dental crown while the patient is at the office having their tooth prepared, eliminating the need for a temporary crown and 6 week fabrication time at a dental lab.

Virtual dental impressions eliminate messy, traditional dental impressions that are sometimes difficult to take, especially on patients with a sensitive gag reflex. The final result is an extremely accurate virtual representation of the tooth that is so detailed that dentists and dental laboratories don’t have to worry about the quality as they do with traditional dental impressions.

This technology has been used since the 1980s, but is becoming increasingly popular in modern dentistry due to the convenience and quality that it allows dentists to provide to their patients.

If you’ve had problems in the past with dentures, crowns or bridges not fitting properly, or simply want to reduce the number of office visits for fitting dentures or other dental treatment, ask your dentist about 3-D virtual impressions with CAD/CAM technology.
