We purchased this equipment in August of 2017 and it’s been a very successful, helpful set-up. It’s saving us money in terms of impression material and our gross profit has increased due to improved speed and increased use.
What’s good about it
Prior to owning the CEREC, our crown preps required manual impressions that were sent to the lab while the patient was given a temporary crown. The patient had to return at a later date, have the temporary removed and the permanent crown fitted.
Now, the whole process is completed in under two hours. We take a digital scan with the CEREC Omnicam, then create a CAD/CAM file. The milling unit then creates a permanent crown from that file. The crown can be fitted to the patient in the same visit. This also means that the patient only needs one dose of anaesthetic for the entire procedure. Patients love the convenience, and people with a heightened gag reflex no longer have to put up with impression material in their mouth.
We also use the scanner for orthodontic cases and Invisalign aligners as the digital impressions are extremely accurate. In dentistry, everything is getting digitised these days and most practices are adopting these types of scanners.
You need to undergo some training to learn how to use the scanner and the milling unit but once you get up to speed, the results are fantastic.
What’s not so good
CEREC are constantly updating their units and my model has already been superseded. The only drawback is that it can’t produce a long span bridge. If a bridge contains three or more teeth then we have to send it off to the lab.
