With new CEREC 3-D imaging and manufacturing system, your visits to the dentist's office can be more pleasant and less frequent.
If you’ve ever had a filling, you know how imprecise they used to be. Often a little hunk of metal was jammed into the tooth, then hammered into some rough shape that relied on the action of your teeth to finish it, while possibly breaking the rest of the tooth in the process. Or if you’ve ever had a crown done, you know the nuisance of having to make several visits to the dentist for diagnosis, then making the impression, then coming back to have the crown finally put in place.
But no more: the new CEREC 3-D imaging and manufacturing system is able to produce minutely specified dental replacements within fifteen minutes!
What is the CEREC system?
The CEREC 3-D system is a state-of-the-art Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) system. It consists of three parts:
- An optical camera that precisely images your teeth as they are, creating a 3-D visual impression of your entire mouth, rather than the manual plaster impressions dentists used in the past.
- A CAD terminal that allows the dentist to manipulate the image, transforming the teeth as they are into the teeth as you want them to be, and in so doing, creating a precise set of instructions that the computer stores.
- A CAM mill where diamond bits shape ultra-hard ceramic hybrid blocks into the precise shapes designed by the dentist using the CAD terminal.
The CEREC system is a marvel of modern technology. Every component is state of the art, from the reflective optical powder used to aid the digital imager to the precisely detailed CAD system to the minutely sensitive robotic arms in the diamond mill.
What are the advantages of the CEREC system?
First and foremost: speed. From the time the doctor sends in the specifications to the time the milled crowns are finished is usually only fifteen to twenty minutes! Compare that to the weeks it took to send plaster impressions to a distant manufacturer.
Second, accuracy and precision. The imaging system provides data at a microscopic level, far more precise than the plaster impressions. The dentist is then able to manipulate this data at the same level of precision. Finally, the diamond mill produces the crowns or fillings exactly as specified by the dentist.
Third, the ceramic crowns and fillings are neither too hard nor too soft for use in the mouth. If crowns and fillings are too hard, they can lead to undue wear on your natural teeth, whereas if they are too soft, they will obviously wear too quickly and need to be replaced. Also, the ceramic expands and contracts at the same rate as your natural teeth, so there’s no danger of your tooth cracking when eating very hot or very cold foods.
Fourth, the ceramic crowns and fillings made by the CEREC system look just like natural teeth, far more so than metal or even porcelain-bonded-metal crowns.
Fifth, because of its speed, it can be easily used as part of a complete smile makeover.
Finally, and perhaps most importantly, the ceramic replaces the possibly toxic metallic compounds that have been used for years in fillings, including mercury in some cases.
Overall, the benefits of using the CEREC system for fillings and crowns are so numerous and so significant that one should not even consider receiving treatments from a cosmetic dentist who does not use the system.
