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. 


Advances in Dentures

Posted in Dentures

Exciting advances in denture production promise to revolutionize the process of fitting new dentures.  The conventional process for having new dentures made usually takes a month or longer and four or five visits to the dentist’s office.  A newly developed procedure reduces the amount of time to about 10 days and the number of visits to just two.

Using cutting edge CAD (Computer Aided Design)/CAM (Computer Aided Manufacturing) systems, Dentca dentures can be produced much more quickly and accurately than conventional dentures.   The conventional method involves taking an impression of the patient’s mouth and gums and sending it to a lab where a “try in” denture made of wax or plastic is made by hand.  This model is sent back to your dentist for you to “try in”.

Your dentist will assess the fit and send the model back to the lab for the necessary modifications.  This process is repeated until your dentist determines that the model fits properly.  Only then is the final denture produced and even then some adjustments may be needed.

With the Dentca denture system, the denture is produced with precision CAD/CAM technology after only a single visit.  The process only requires two visits to the dentist’s office:  one visit for the impressions to be taken and one for final delivery of your new dentures.  You will spend far less time in the dentist’s chair and your new dentures can be ready in only ten days.  In addition, since the dentures are produced using precision CAD/CAM technology instead of being produced by hand which eliminates human error and minimizes uncomfortable fitting problems.
