There are really many different ways to beautify teeth, and the names are not good enough. Many people will confuse the difference between all-ceramic teeth and porcelain teeth. Xiaobian thinks it is necessary to popularize the knowledge for you. Pay attention to the lecture. Difference between porcelain teeth and all-ceramic teeth

Different appearance

Porcelain teeth: Porcelain teeth are a combination of metal materials and porcelain materials, which have poor light transmittance in appearance. After being used for a long time, porcelain teeth will show "black lines" at the gums, which is due to metal microleakage, and some patients will have allergic symptoms.

All-ceramic teeth: All-ceramic teeth are made of porcelain materials, which are natural and beautiful from the angle, and are closer to the external light and gloss of the teeth themselves.

different hardness

porcelain teeth: the hardness of the material is greater than enamel, and the force generated when occluding with the body teeth is greater than that when occluding with all-ceramic teeth. Porcelain teeth are more suitable for posterior teeth restoration because of their greater hardness and occlusal strength.

All-ceramic teeth: The hardness of porcelain blocks cast by all-ceramic teeth is slightly softer than that of porcelain teeth materials, but all-ceramic teeth are completely made of porcelain powder and then produced at high temperature, which leads to limited occlusal resistance of ceramic crowns. All-ceramic teeth can only be used to make a single tooth, not a fixed bridge designed for missing teeth.

Different biocompatibility

Porcelain teeth: Because of the existence of metal-based crown, some metal microleakage and metal allergy can't be avoided. Clinical investigation shows that 2% people are allergic to the metal composition of porcelain teeth. Once the porcelain teeth are made, urticaria, eczema and other diseases occur, which are all caused by the slight exposure of the metal components of the porcelain teeth.

All-ceramic teeth: All-ceramic teeth have better biocompatibility than porcelain teeth with metal bases, and will not produce gold coins, which is an allergic phenomenon and will not cause allergic reactions (urticaria, etc.) to the skin.

Different adaptation parts

Porcelain teeth: The crack resistance is better than all-ceramic teeth, so porcelain teeth are often used for posterior teeth restoration.

All-ceramic teeth: All-ceramic teeth are mostly used for the restoration of anterior teeth (such as single crown, inlay, high inlay and veneer restoration) because the porcelain block of porcelain teeth is slightly soft.

different prices

porcelain teeth: the equipment is relatively simple and the cost is relatively low.

All-ceramic teeth: The production of all-ceramic teeth requires special equipment, which requires a high level of doctors' operation, which is time-consuming, laborious and expensive. Which is better, porcelain teeth or all-ceramic teeth?

porcelain teeth are not as beautiful as all-ceramic teeth.

porcelain teeth are not as beautiful as all-ceramic teeth, and it is best for patients to choose all-ceramic teeth in the case of pursuing appearance. The permeability of all-ceramic teeth is a difficult effect for ordinary metal porcelain teeth. Because the inner crown of porcelain teeth is opaque, it is necessary to cover the metal base with opaque porcelain, which will affect the transparency of the restoration to a certain extent, making the porcelain teeth have obvious chalk color after beauty treatment, which is different from the gloss of real teeth. And porcelain teeth may have a "black line" in the gums, which will affect the appearance. All-ceramic restorations solve this cosmetic problem with good transparency and refraction.

The compatibility of porcelain teeth is not as good as that of all-ceramic teeth

The compatibility of porcelain teeth is not as good as that of all-ceramic teeth. If you want to be allergic after finishing your teeth, you'd better choose all-ceramic teeth. The reason why people who are allergic are advised to choose the whole word is because the biocompatibility of all-ceramic teeth is obviously higher than that of porcelain teeth. All-ceramic porcelain restorations are more adaptable in oral cavity than any other metal porcelain teeth, so there is no need to worry about metal allergy, which will cause gingival swelling and bleeding. No sensitive cases were found in all-ceramic teeth, and all-ceramic teeth prevented gingival discoloration, especially nickel and beryllium metals oxidized in the mouth to form gray oxides, which were scattered and deposited on the gingival edge, causing gingival graying and affecting aesthetics. All-ceramic restoration completely solved these shortcomings.
