CEREC Crowns represent a CAD/CAM technology whereby patients are able to receive their crowns in 1 surgery and you don’t have to have a temporary crown placed. Until recently, CEREC Crown technology was not advanced enough to allow this to occur. So patients needed to receive a temporary crown and then a few weeks later the final implant would be fabricated and it would be received in a 2nd surgery.
CEREC stands for ceramic reconstruction, and over 25 million porcelain crowns have been milled since the technology first became available.
In addition to porcelain crowns, veneers, onlays, and inlays can be prepared using various types of ceramic materials.
With CEREC crowns patients are able to receive a new crown the same day, and that crown is very strong, durable, and it is able to be used the same day. The implant is placed start to finish including anesthesia, tooth preparation, impressions, ceramic fabrication, and implantation. The procedure involves grinding the tooth down, taking a picture of the tooth, sending that information to the 3-D technology computer, and then that computer designs the implant specifically for your mouth.
More specifically once the software renders the specific implant for your mouth, that information is then sent to the CEREC computer. This computer allows the machine to mill the porcelain crown, and the porcelain crown is then checked specifically for your mouth. To make sure that it was made properly for your mouth, the implant is checked against your bite, along with making sure that the appropriate color of the porcelain block was chosen to complement the rest of the teeth in your mouth.
The implant is fashioned using diamond burs.
The dental materials used for the crowns match the composition of natural tooth structure. So when hot or cold foods or drinks are consumed the implant material will expand and/or contract at rates about half way in between enamel and dentin. It also deteriorates at about the same enamel.
