CADCAM CEREC Crowns
CEREC® technology (http://www.sirona.com) designs and mills solid-block ceramic crowns and onlays in a single visit. No need for impressions, temporaries, delivery visits or a second time getting numb!
How does CEREC® CAD/CAM work?
CEREC®'s bluecam LED camera captures an optical impression of your damaged tooth. The camera communicates the optical impression to 3D CAD (Computer Aided Design) software that designs a restoration to the exact contours of the tooth to be restored. CAM (Computer Aided Manufacturing) technology automatically mills the crown or onlay with two high-speed diamond burs at our milling station while you watch!
CEREC® crowns and onlays are
Bisphenol A and B-free
They preserve healthy natural tooth structure. And they're strong! CEREC®'s decades of clinical research and documentation indicate that 84.5% of CEREC® restorations are still viable eighteen plus years after original placement in the mouth. Some clinicians predict that CEREC® crowns and onlays - milled from solid-block ceramic rather than heat processed and layered over metal alloys in the lab - may last many patients a lifetime (longevity represents less trauma to the nerve of the tooth over the lifespan of that tooth).
CEREC® restorations exhibit the same refractive qualities as natural tooth enamel for precise color match and the same thermal qualities as natural tooth enamel for ideal expansion and contraction. Their similarity to natural tooth enamel eliminates the wearing of opposing teeth, a common problem with lab-fabricated porcelain-fused-to-metal crowns.
Finally, with CEREC®, there is no metal substructure; the oral galvanic current (see our section on oral galvanism) generated by lab-fabricated porcelain-fused-to-metal crowns is completely eliminated.
Dentistry exquisitely simplified!
