Many people may mistakenly think that all-ceramic teeth are porcelain teeth, and there is no difference between them. But in fact, this is not the case, but it can be seen from the price of both. Generally, all-ceramic teeth cost several thousand yuan, which is far more expensive than ordinary porcelain teeth. So why are all-ceramic teeth so expensive? Let's look at the difference between all-ceramic teeth and porcelain teeth.
The difference between porcelain teeth and all-ceramic teeth is that all-ceramic teeth are transparent in appearance and more like real teeth, which is an arduous task for porcelain teeth. The metal crown of porcelain-fused-to-metal teeth is opaque, so it is necessary to cover the metal with opaque masking porcelain, which affects the transparency of the restoration, making the porcelain-fused-to-metal teeth appear obvious pink, pale and false after cosmetic treatment, and there is a "black line" formed by the metal base at the neck of the teeth, which affects the appearance.
All-ceramic teeth have good transparency and shading, and the high-strength inner crown has dealt with this cosmetic stubbornness, which makes the tooth neck have good aesthetic effect. The hardness of porcelain teeth is greater than enamel, which will cause damage to jaw teeth, while the hardness of all-ceramic teeth close to enamel will not cause damage to jaw teeth.
Ordinary porcelain teeth are relatively low in price and are widely used in China at present. However, porcelain teeth have the following defects: poor marginal fit and poor compatibility with human body. Some patients will have black lines on their necks after wearing them for a period of time, and there are allergic phenomena similar to porcelain teeth abroad, but all-ceramic teeth do not have these problems. These are the differences between porcelain teeth and all-ceramic teeth.
