CEREC: State of the Art Dental Restorations

Posted on: March 2, 2019

The creators of CEREC technology know that many people are likely to put off dental work that requires multiple dentist's visits to complete. So they used CAD/CAM (Computer Aided Design/Computer Aided Manufacture) technology to come up with a way to help dentists fabricate and place same-day restorations.

CEREC is used to make restorations like dental crowns, bridges, onlays and inlays. Before CAM/CAD technology, such restorations took a few days to fabricate.

How does CEREC work?

Same-day restorations are placed in a single procedure which takes a relatively short time. Here is what a person should expect when they go in for a same-day crown, bridge or onlay:

1. The dental exam

It all starts with an exam that helps determine the type of dental restoration a patient needs. The dentist will look at the tooth to determine how much damage they have to fix.

If the tooth is only slightly damaged, the dentist may choose to fill it instead. If the damage is extensive, the dentist will choose either an onlay or a dental crown. If the tooth is missing, the dentist will choose a bridge.

2. Preparation

The dentist will numb the tooth and remove decayed and dying dental tissue. If the patient has a worn filling, that is what the dentist will remove first. Next, they will clean the tooth to remove any leftover debris. Lastly, the dentist will prepare the enamel to allow the restoration to fit well and adhere to the tooth.

3. Digital impression

In order to make the restoration, the CAD/CAM system will need a 3D digital impression of the patient's teeth. The dentist will use a digital camera to scan the patient's mouth and take images of their teeth. The camera is set up to feed the image directly to a computer with CEREC software.

4. Design

The CEREC software processes the images and converts them into a 3D model of the patient's mouth, including the prepared tooth. The dentist uses the model to design a restoration that fits perfectly onto the prepared tooth and blends in with the rest of the teeth.

During the design phase, the dentist will also choose a tooth color that matches the patient's other teeth. They will pick or fabricate a block of high-quality porcelain with that specific color.

5. Fabrication

This is where the CAM part of CEREC technology comes in. Using the design created by the dentist, CEREC uses a milling unit to fabricate the restoration. Think of the milling unit as a printer and the dentist’s design as the document to be printed.

The miller has a set of burrs that sculpt the block of porcelain into the shape of the onlay, crown or bridge. The resulting restoration has the exact dimensions, shape and color specified by the design.

6. Placement

The dentist smooths and polishes the fabricated restoration and places it onto the prepared tooth.

Benefits of CEREC restorations

The following are some of the advantages and benefits of getting a CEREC restoration:

  • The porcelain used to make the restoration expands and contracts just like a natural tooth
  • It only takes a single procedure to restore a tooth
  • There is no need for a patient to take gag-inducing impressions using dental putty
  • Thanks to CEREC, the dentist is able to remove the least possible amount of enamel when preparing a tooth for a restoration
