When an impression is taken it is influenced by the quality of the material used, the conditions in the mouth (i.e. Some of this has to do with the accuracy of the impression model itself. However, studies show that CEREC crowns actually have significantly lower deviations regarding their similarity to original tooth morphology, the number of occlusal contacts, occlusal adjustment time, and subjective aesthetic perception. So you can see that even when we use CAD/CAM technology to create your crown in our lab, we’re using similar methods that outside labs use. When it comes to making dental impressions for a restoration, almost all labs have scanners that convert the impression models into a digital form to design and mill the final restoration. E-Max case study examined at Dental Compareīoth Offsite Labs & CEREC Offices Use Digital Scans, But Only CEREC Uses a Direct Scan.E-Max case studies examined at Glidewell Laboratories.CEREC case study at Global Dental Solutions.With good home-care and regular preventative visits to our office, you can expect your E-Max restorations to last 15 years and even beyond.Ĭheck out these case studies showing how long-lasting E-Max porcelain restorations are: It blends seamlessly with your natural teeth and is less likely to chip when compared to zirconia. It’s known for its strength and aesthetic qualities. James Powell can create your crown from E-Max porcelain.Īnd while the idea of porcelain in your mouth may conjure images of a fragile figurine lying shattered in pieces on the floor, an E-Max restoration is actually made of an extra strong, long-lasting material and is even considered a breakthrough when it comes to dental crown technology.Į-Max is made from a durable, aesthetically-pleasing top-grade material and is made from a single block of lithium disilicate ceramic. Using CEREC’s state-of-the-art CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) technology, our dentist, Dr. And both labs and CEREC offices use the same kinds of materials when crafting dental crowns. The two most common materials used for crowns are E-Max and zirconia. You might not know it, but both off-site labs and CEREC restorations have a lot of similarities. And it’s time to debunk that misconception! CEREC Crowns vs. While some patients are tempted to buy into the myth that CEREC crowns are inferior to lab made crowns, in reality, nothing could be further from the truth. So, when a crown is indeed needed it’s logical that you want to make sure that you’re getting something that is going to look good, feel good, and last. They are used to fortify a tooth that’s been plagued by severe decay or damage and are often the crowning glory (ha) after a root canal treatment or a dental implant. The main difference between onlays and crowns is that a crown fits over the whole tooth. But when the decay & resulting damage is more extensive a larger restoration like an onlay or a crown might be necessary.
If decay is caught early enough then you might only need a filling. It’s important to understand that crowns, both types, are a form of restorative dentistry and the ultimate goal of restorative dentistry is to get your teeth back to their natural state (free of damage and decay). Which means, it’s likely that you’ll face the conundrum of CEREC crowns vs lab crowns. Once you’ve been told you need a dental crown you might find yourself researching to understand everything about them.
