"The one appointment crown"
CEREC - stands for Chairside Economical Restorations of Esthetic Ceramic
These are porcelain restorations that are fabricated using CAD-CAM technology....
.... where a digital picture of a tooth prepared for a crown is taken by a camera connect to a computer
.... that picture is then used to design the crown on the computer
.... the image of the designed crown is sent to a milling chamber
.... where the crown is milled from a block of solid porcelain to within 10 microns of accuracy - that's pretty accurate!
.... the crown is tried on the prepared tooth, polished and cemented.
..... All in one appointment - simply AMAZING !!!
