Do you know dentistry, wow, I went to fill the big tooth today, I had root canal treatment before, a

Well, the amalgam turned out to be 200, it's too pit, if it's a professional dental hospital, you can endure it, and the dental hospital of our school is only more than 100 composite resin. . . In fact, amalgam is very good, there are many advantages, but the technical requirements for doctors are relatively high, the biggest disadvantage is that it is not good-looking, if the landlord corresponds to the maxillary back teeth without a metal crown, there is no problem. Personally, I don't think there is a need to re-do it,,, if the landlord insists on looking good, then there is no way, you can grind and change the resin.

I want to ask, what does it mean to have a root canal ** before, and did you not make up for it after doing the root canal**?

Amalgam is not toxic, many people may think that amalgam is toxic, our teacher said that only long-term contact with people may have, that is, even if there is harm, the injured person can only be the doctor, the patient is unlikely to have an impact, I said, its disadvantage is only the color is not good-looking, and the other is that the retention is not good, but you may not understand it very well. It won't affect you anyway. We wrote a sentence in the book:

In the past year, with the continuous development of new materials and equipment for oral restoration, the position of amalgam in dental restoration has changed, but due to the lack of physical and chemical properties of resin and glass ionic tooth color materials, it is not yet possible to completely replace the position of amalgam in posterior tooth filling restoration.

Nowadays, hospitals and clinics do not supplement amalgam because it is too troublesome and it is not good for themselves, so they are gradually not used.

The advantages and disadvantages of mercury are obvious. It is not recommended to replace the back teeth, because it is best to do crown protection after the root canal ** of the back teeth, and the mercury is not visible in it.

Whether it is a direct filling or a complete root canal** filling, there are many materials for patients to choose from. There are many types of materials used to fill teeth:

The characteristics of amalgam are that they are strong, not easy to wear, easy to use, and safe.

Safety of Amalgam The following are the questions that the general public has about amalgam: Amalgam contains mercury, and mercury is toxic, is it safe to use amalgam? Amalgam is a mixture of metals of different compositions, such as **, copper, tin and mercury.

When mercury is mixed with other metals, it becomes very stable. It is only under tremendous pressure and wear that amalgam releases very small amounts of mercury. The amount of mercury released from amalgam is negligible compared to the amount of mercury absorbed by the human body from food, drinking water and air every day.

Should the patient remove the amalgam from the mouth to avoid serious diseases such as Alzheimer's disease?'s disease) and so on? At present, there is no scientific literature to confirm that the removal of amalgam can lead to the recovery of the patient's disease, and there is no evidence that there is a direct relationship between the two. Unless the patient has an allergic reaction to the amalgam, it is not appropriate to replace the amalgam.

As of 2014, amalgam is the safest and most effective material for dental fillings. Other filling materials, such as composite resins, are not as durable as amalgam and are not suitable for filling gaps that are too large. Some metal materials, such as **, are also effective fillings, but they are very expensive.

Do some people have an allergic reaction to amalgam? Only a very small number of people will have an allergic reaction to amalgam (only 100 cases have been recorded in more than 150 years of use). Such patients should choose to use other filling materials.

You're making up for mercury?? That's it, mercury is toxic and not good for the body, and few people use that material nowadays.

Several common filling materials today look something like this:

Cobalt chromium: 500 1000, this biocompatibility is better, cost-effective, and the gums will not turn black and allergic, and do not contain carcinogens, but also the most popular porcelain teeth in Europe and the United States, widely used by everyone, recommended use.

Titanium alloy: It's similar to cobalt chromium**, but it's purely a money scam! In fact, the composition is similar to nickel chromium, and the composition of titanium is very small, and insiders revealed that titanium alloy is actually just a disguised increase in charge.

Gold-palladium alloy: This material does not darken the gums, but it is higher, around 1500.

Pure titanium alloy: If the economic conditions are better, it is recommended. Because this material does not darken the gums, it does not affect the MRI, that is, if you go to the hospital in the future, it will not affect the results of the examination.

**It's similar to gold-palladium alloy, but better than that.

Finally, ***: It looks like more than 3000, the specific price is not very clear, few people do it, inlaid with gold teeth is like a leopard, it is expensive to death, and it is not as good as pure titanium, *** will also affect the effect of nuclear magnetic resonance, and I personally think it is meaningless.

ps: Because I make cobalt-chrome porcelain teeth, so I know a little more, the best brand of cobalt-chrome porcelain teeth is bego from Berg in Germany, followed by Ivoca-Carl in Switzerland, and these two brands provide quality assurance cards and guarantee for five years, generally available for more than ten years. It is recommended that friends who go to have teeth ask the doctor what brand of porcelain teeth he uses for you, and be sure to ask him for a warranty card, which is very important.

The clinic where I went to do my teeth was from Berg, Germany, and it was good.
