There are really too many different ways to beautify teeth, and the names are not bad. Many people confuse the difference between all-ceramic teeth and porcelain teeth. I think it is necessary to give It's time for you to spread knowledge. Please pay attention. The difference between porcelain teeth and all-ceramic teeth
Different appearances
Porcelain teeth: Porcelain teeth are a combination of metal materials and porcelain materials. They have poor light transmittance in appearance. After using porcelain teeth for a long time, "black lines" will appear on the gums. This is due to micro-leakage of metal, and some patients will have allergic symptoms.
All-ceramic teeth: All-ceramic teeth are made entirely of porcelain materials, which look natural and beautiful from an angle, and are closer to the appearance and gloss of the teeth themselves.
Different hardness
Porcelain teeth: The hardness of the material is greater than that of tooth enamel, and the force generated when it bites with the main teeth is greater than that of all-ceramic teeth. Because porcelain teeth have greater hardness and stronger biting force, they are more suitable for use in the repair of posterior teeth.
All-ceramic teeth: The hardness of the porcelain block of all-ceramic teeth is slightly softer than that of porcelain teeth. However, all-ceramic teeth are completely made by porcelain powder accumulation and high temperature, which causes the ceramic crown to resist occlusion. The power is relatively limited. All-ceramic teeth can only be used to make single teeth and cannot be used to make fixed bridges designed for missing teeth.
Different biocompatibility
Porcelain teeth: Due to the presence of metal base crowns, porcelain teeth cannot avoid some metal microleakage and metal allergies. Clinical surveys have found that 20% of people are allergic to the metal components of porcelain teeth. Once porcelain teeth are made, urticaria, eczema and other symptoms may occur because the metal components of the porcelain teeth are slightly exposed.
All-ceramic teeth: All-ceramic teeth have better biocompatibility than porcelain teeth with metal bases, will not produce gold coin allergies, and will not cause allergic reactions on the skin (urticaria, etc.) .
Adapted to different parts
Porcelain teeth: The crack resistance is better than that of all-ceramic teeth, so porcelain teeth are often used to repair posterior teeth.
All-ceramic teeth: Since the hardness of porcelain teeth is slightly softer, all-ceramic teeth are mostly used for the restoration of front teeth (such as single crowns, inlays, onlays and veneers).
The prices are different
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, requires a high level of operation by doctors, is time-consuming, labor-intensive, and expensive. Which one 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. When the patient pursues appearance It is best to choose all-ceramic teeth. The permeability of all-ceramic teeth is an effect that is difficult to achieve with ordinary metal-ceramic teeth. Because the metal inner crown of porcelain teeth is opaque, opaque porcelain needs to be used to cover the metal base, which will affect the transparency of the restoration to a certain extent, causing the After the porcelain cosmetic treatment, there is an obvious chalky color, which is different from the gloss of the real teeth. In addition, porcelain teeth may also appear "black lines" on the gums, affecting the appearance. All-ceramic restorations solve this cosmetic problem with good transparency and refractive properties.
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-porcelain teeth. If you want to avoid allergy after dental treatment, it is best to choose full-porcelain teeth. Porcelain teeth. The reason why it is recommended that people who are prone to allergies choose Quanci Ya is because the biocompatibility of all-ceramic teeth is obviously higher than that of porcelain teeth. The adaptability of all-ceramic dental restorations in the oral cavity is higher than that of any other metal-ceramic teeth. There is no need to worry about problems such as metal allergies. Metal allergies in porcelain teeth can cause gum swelling, bleeding and other phenomena. There are basically no cases of sensitivity found with all-ceramic teeth, and all-ceramic teeth can effectively prevent gum discoloration. In particular, nickel and beryllium metals oxidize in the mouth to form gray oxides, which are scattered and deposited on the edges of the gums, causing the gums to turn gray and affecting the appearance. , all-ceramic restoration completely solves these shortcomings.
