CEREC and EMAX Crowns
What is a CEREC Crown? How is EMAX different?
CEREC (Chairside Economical Restoration of Esthetic Ceramics) is a computer-aided design that allows Dr. Kenney to construct, produce, and insert individual ceramic restorations directly chairside in a single appointment, rather than over multiple appointments with lab side work in-between. In addition to being more convenient than other types of crowns, CEREC crowns are made from a single block of material, making them considerably stronger than many other types of crowns. An EMAX crown takes the CEREC a step further. EMAX has the same steps as a CEREC when it comes to fabricating, but this crown is made from a single block of lithium disilicate ceramic. This top-grade material has been harvested for its toughness, durability, and opaque qualities, which make for a highly prized crown.
How long does the process take?
Unlike the two- to three-week wait that is customary for traditional crowns, CEREC and EMAX crowns are crafted during a 1 ½ hour to 2-hour dental visit. For approximately 45 minutes of that time, however, you will be comfortably relaxing and able to read one of our many available magazines or catch up on emails on your mobile device while using our complimentary Wi-Fi.
How do CEREC/EMAX Crowns differ from Porcelain Crowns?
Traditional porcelain crowns are created in a dental laboratory using impressions of your teeth. Dental labs typically take one to two weeks to provide a lab-created crown to your dentist, at which point you will need a follow-up appointment to have the crown permanently cemented.
CEREC crowns are created using computer-assisted (CAD/CAM ) technology. Instead of impressions, the dentist requires an image acquisition unit with an intraoral camera, a corresponding designing software, and a milling machine, all which allow for a more perfect fit and color match, making your crown a more custom fit to personalize your smile.
EMAX crowns are a type of all-ceramic crown with an appealing translucent color, combined with extra strength and durability. You get a glass ceramic crown which is tough and enduring, but delicate in appearance. EMAX and CEREC crowns have no metal alloy base, which means no unsightly looking grey line around the gum and a perk for anyone with alloy allergies.
What is the procedure for receiving a CEREC/EMAX Crown?
Using a small intraoral camera, Dr. Kenney will scan the tooth and take a 3D picture. Using the scanned image, Dr. Kenney will design the crown to match the color of the surrounding teeth. A special machine will mill the crown from a solid block of high-grade ceramic. Once the crown is milled, Dr. Kenney will place the crown and get you on your way in less than two hours from start to finish.
Who is a candidate for CEREC/EMAX Crowns?
Patients who have had a root canal or are looking to repair broken, fractured, or decaying teeth are ideal candidates for CEREC crowns. Particularly for those patients who are in pain and need an immediate solution, CEREC crowns are ideal. This also applies to EMAX crowns, but EMAX also are beneficial for patients with a hard or tight bite and anterior teeth that need a crown. EMAX has a highly attractive appearance that can be aesthetically appealing for patients. This is something Dr. Kenney will discuss with you to help choose which crown is best for you.
