The CEREC crowning system is one of the most exciting and ground-breaking advancements in modern dentistry, allowing your dentist to create a bespoke porcelain crown in a single appointment. But how do CEREC crowns differ from traditional crowns?
CEREC: time-saving and convenient
If you’ve ever had a crown fitted the conventional way, you’ll know to expect to attend at least two appointments and several weeks of waiting between the two. The first appointment is an initial consultation where your dentist will take an alginate impression of the tooth being crowned, which is then sent to an off-site dental lab where the crown can be made up. In contrast, CEREC crowns require a single appointment and for this reason, no replacement crown is necessary whilst your crown is being made up.
Digital impressions mean improved patient comfort
In order to create a crown, your dentist needs an impression (or mould) to work from so they can create the crown in the image of your smile. The traditional method of making a crown involves taking alginate impressions, which use a notoriously uncomfortable gloopy impression material that induces a gag reflex in many people. The CEREC system has recourse to digital impressions that take a simple scan of your teeth – no more unpleasant impression material. Digital impressions are also less time-consuming because they eliminate the inaccuracies or accidental movements that frequently occur with alginate impressions, meaning fewer retakes.

Both traditional crowns and CEREC crowns have a great reputation when it comes to durability. Clinical studies have shown that the success rate of CEREC restorations is 95.5% after a period of 9 years and 84% after 18 years. Dental crowns can last for 30 years if properly cared for and can be cared for in the same way as your existing teeth, requiring no special attention.
CAD/CAM software is used to create your crown
CEREC is a computer, camera, and accurate manufacturing machine all in one. An image of the damaged tooth is taken and the Computer Assisted Design (CAD) element designs the porcelain restoration. The Computer Assisted Manufacturing (CAM) is tasked with milling the restoration from a block of porcelain while you wait in the waiting room. Once this is complete, we can bond your crown and make any minor amends necessary.
