Decayed crown was restored and for more than a hundred years, broken down teeth. Gold crown was best for many years. When people wanted a restoration that was the color of a tooth. One way porcelain (glass) made of metal binding was invented. The bath tub, kitchen sink and was used for many other things as well. Dental apply technology to create a crown for a tooth. Fused to a metal crown is called porcelain.
The crown of sizes and colors can be made to look like a tooth and is strong enough. Metal is not strong enough to need to flex. If it flexes, the porcelain will fracture off. Also, the metal is dark. Out it should be blocked by opaque porcelain. Thin layer of porcelain color on the can to the color you want to be. The problem is that unlike natural tooth enamel, a porcelain fuse to metal crowns do not allow light to come through. The crown is quite ugly leaves a dark line on the gum line.
New research did not include strong enough to stand on its own with metal porcelains have been brought about. All porcelain crown light transmitted through them and they look very natural. A dark gum line. Look no opaqued.
However, these crowns require at least two dental appointments:
* The first dental visit to prepare the teeth and taking impressions. Impression that the dental lab where they are sent to the Taj building. Meanwhile, a temporary crown is placed for about two weeks.
* The second dental visit, the temporary crown removed and the permanent crown is cemented in place.
However, once again, technology process has taken the crown to the next level -
It is called CEREC!
Cerec machine about an hour the whole process, saving you hours of the second dental visit and their time.
First, the porcelain crown is made of 100%. It is cintered which means pressure and heat of that to make their properties as hardness and wear the enamal is put under.
Second, there is no reason to pick up and send to the lab's impressions. Cerec crown a CAD / CAM is used with the machine. CAD and CAM stands for Computer Assisted Design for Computer Assisted machine.
Cerec tooth with an infrared photo taken and brought into the computer. Computers now the dentist crown design. Next, a block of porcelain is placed in a milling machine. Milling machine designed for the dentist sends the crown. Cerec milling machine mills the crown out of porcelain and takes the block. Milling process takes about 10 to 15 minutes.
Third, porcelain crown is removed from the mill. Now the dentist porcelain crown using a new generation of cements cements that bond to teeth and porcelain. Gives additional power to the new restoration. A good example is a thin piece of laminate is very weak and brittle at the same, but the strength of wood bonded to gain a great deal.
Cerec crowns are very natural looking, a very precise fit, are durable and a dental visit can be done in about an hour, saving you hours of time.
I hope this is of some interest Cerec 3-D imaging process works and how to find a more and more knowledge.
