Root canal therapy is a common treatment method for pulpitis and pertine inflammation. By killing the tooth nerves, the infection in the root canal is removed, thereby keeping the affected teeth.

However, the teeth after the root canal treatment will become very fragile, and you need to wear crown to protect it. The common crowns are mainly metal, porcelain teeth, and all -porcelain teeth.

But these three types of crown are very different. What is the difference between them? How should ordinary people choose?

What is metal teeth, porcelain teeth, all porcelain teeth?

Metal tooth, porcelain teeth, and whole porcelain teeth are crown that can be used as oral repair

The difference between them is mainly to make different materials

1 metal teeth

Metal is the most traditional denture repair material. It has a long history. It can be said that the older generations basically come from metal teeth.

Because the metal has high strength, the metal teeth made are also stronger and wear -resistant, have good solid strength, and at the same time, metal teeth also have the advantages of simple production process and cheap price.

2 porcelain teeth

Porcelain teeth refer to the crown of the metal inner crown and the outer layer of porcelain.

It can be simply understood that the porcelain teeth are added with a layer of ceramics on the outer layer of the metal tooth, so that the crown has the practicality of the metal teeth, and takes into account the beauty of the appearance. It is not easy to deform and has certain corrosion resistance.

3 All -porcelain teeth

All porcelain teeth refer to the crown made of ceramic materials.

When the whole porcelain teeth were just invented, although the appearance was beautiful, it was not widely used due to the shortcomings of crispyness, cracking and broken breaks.

However, in recent years, with the successful development of alumina and oxide materials, the intensity of all -porcelain teeth can meet the majority of repair needs, and the indications have become wider and wider.

From the perspective of development history, the history of metal teeth is longer than the porcelain teeth and all -porcelain teeth, but now few people are inlaid. Why is this?

Why can't you see golden teeth now?

Although metal teeth are cheap and durable, there are 3 remarkable disadvantages, which has caused it to be eliminated now:

① Not beautiful

Not beautiful is the most significant disadvantage of metal teeth. Now most people do not like a blocked golden teeth or silver teeth. It feels rustic and not good -looking.

② Easy to allergies

Although the metal teeth are cheap, the biocompatibility is not good. Some people are allergic to the metal crown, and some metals will also make metal ions in their mouths, causing the gums to be black, and even the infection of the base tooth.

③ Affect MRI

Some metals, such as cobalt chromium alloy, nickel complex alloy will produce pseudo -shadows in the nuclear magnetic resonance examination. Many patients with metal teeth were told to remove the crown before nuclear magnetic resonance.

Although some precious metals, such as gold alloy and titanium alloy, have a small impact on MRI, but using precious metals also means higher prices. At this time, metal teeth are no longer a cost -effective choice.

Is it generally recommended for all porcelain teeth because it is expensive?

In order to solve the disadvantages of the unsightly metal teeth, porcelain teeth have been widely used for a long time, but there are also disadvantages of porcelain teeth-

Before wearing a tooth crown, the teeth must be smaller. The amount of molars required for porcelain teeth is more than metal teeth, because porcelain teeth are thicker, with two layers (inner metal + outer ceramics).

Because the inner crown of the porcelain tooth contains metal components, it will still affect the nuclear magnetic resonance. After a long time, it will also make the gum edge blue and black.

After removing the crown, red, swollen and black gums

Therefore, with the continuous development of oral repair materials, metal teeth and porcelain teeth are gradually replaced by whole porcelain teeth.

How good is the current all -porcelain teeth?

① Strong and wear -resistant: The current all -porcelain tooth material is mainly oxidized. This material has high strength, density, and accuracy. Therefore, there is no need to cut off too many real teeth when the dental preparation;

② Aesthetic effect: All -porcelain teeth have good transparency and foldability, and the color is naturally close to native teeth;

Full porcelain teeth have good light transmission

③ Good biocompatibility: The biocompatibility of oxide is better than metal alloys, which will not cause allergies, nor will the gums black;

④ Strong reliability: Oxidation is a high -tech biomass, which does not contain metal, so it will not affect the nuclear magnetic resonance imaging.

However, some patients still have complications such as bite pain and gum injury after wearing all -porcelain teeth. Why?

What is the better choice than all porcelain teeth?

Traditional all -porcelain teeth are made, which requires patients with diatomic mud, make tooth printing, gypsum molds, and then send them to the factory to produce teeth, and finally send them back from the factory.

The tooth model made by gypsum inverted

The whole process mainly depends on the technology of doctors and technicians, and it takes a long time, which takes about one to two weeks.

At the same time, the crown of the dental crown may occur high, the edges are sharp, and incompletely fit. Therefore, some patients have symptoms such as bite pain and gum damage. Doctors need to be grinded and trimmed in follow -up.

Now, an advanced technology has been widely used in the production of all -porcelain teeth -3D printing full porcelain teeth!

new technology

3D print all porcelain teeth

This technology simplifies the production process of the crown. Doctors scan the patient's oral conditions with the oral scanner, import the computer, and perform the crown design on the computer software. You can print the teeth with a 3D printer at the scene and put it on the patient.

This not only greatly improves efficiency, so that patients can wear their teeth on the day of the hospital. At the same time, the all -porcelain teeth printed by the machine are more accurate and more fit than hand -made. It's right.

3D printed teeth

The price of all -porcelain teeth is very different because the optional price range produced by different manufacturers can be selected for patients with different consumption levels. At the same time, individual brands still have the problem of brand premium.

As for 3D printing full porcelain teeth, because relying on new technology is not a certain product, the price is relatively stable

However, the biggest problem of 3D printing full porcelain teeth is that there are currently few hospitals that introduce 3D printing technology. Only a small number of hospitals can do it. For patients needed, consult the local hospital by themselves.

Tooth 3D printer

Finally, what kind of crown is recommended, it is recommended that you choose 3D printing full porcelain teeth ＞ Ordinary whole porcelain teeth ＞ Porcelain teeth ＞ Metal tooth.
