What kinds of all-ceramic teeth are there? All-ceramic teeth are the most beautiful among many porcelain teeth, so all-ceramic teeth are often used for tooth shaping of front teeth. There are many kinds of all-ceramic teeth, and many patients have not fully understood them. Knowing more about an all-ceramic tooth will give them more choices. So, what are the types of all-ceramic teeth? Chongqing new era oral beauty experts introduce you.
What kinds of all-ceramic teeth are there?
First, cast all-ceramic teeth.
Casting all-ceramic teeth, this is to make the corresponding tooth model with wax, then remove the wax at high temperature, and finally melt the made porcelain block and cast it into a circle by pressure, and the finished all-ceramic teeth are finished. To put it simply, the manufacturing process of casting all-ceramic teeth is to take the tooth mold and cast it as a whole. Cast all-ceramic teeth have beautiful appearance, good translucency and refraction similar to enamel, so the cosmetic effect of teeth is closer to that of natural teeth.
Second, alumina all-ceramic teeth
All-ceramic teeth prepared by powder slurry coating method are formed by coating alumina powder slurry on fire-resistant tooth model at high temperature. Zirconia all-ceramic teeth have high strength and toughness, which has been proved to be successfully used in the thermal shield of space shuttle, brake disc of Porsche car, artificial transmission belt, etc., and its toughness is far greater than other known non-metallic ceramics.
Three, zirconia all-ceramic teeth
Zirconia is a mineral existing in baddeleyite in nature. 1970s, the famous VITA company in Germany invented In-Ceram technology, which greatly improved the strength of all-ceramic crowns and quickly applied it to clinic. The realistic aesthetic effect of all-ceramic crowns shocked dentists, and even dentists could hardly tell which one was a false tooth. Zirconia all-ceramic teeth are made by powder slurry coating, that is, zirconia powder slurry is coated on the refractory tooth model and molded at high temperature.
Fourth, computer porcelain teeth
With the development of material science and computer technology, CAD-CAM technology (computer aided design, laser scanning and computer program controlled grinding) has been applied to the manufacture of all-ceramic teeth. Computer porcelain deposited all-ceramic teeth are made by computer cutting and grinding all-ceramic technology, using CAD/CAM system, forming inner crowns through computer-aided design and processing, and then firing at high temperature. The computer porcelain deposition technology of all-ceramic teeth requires high requirements, and doctors must have a high clinical level to prepare teeth into suitable shapes. The bonding of all-ceramic restorations also requires special materials, which means that only high-level restorers can master the technology well.
