Is there any harm in nickel chromium porcelain teeth? Is it a quality problem that the metal is expo

1 Modern medicine has proved that nickel is allergenic and carcinogenic to the human body, which can cause slight inflammation of the gums in some people, resulting in slight redness and swelling in the contact between the porcelain teeth and the gums, which is harmful to the health of the gums and affects the appearance.

2. The chemical properties of nickel are unstable, and after the precipitation of metal ions, there is an oral odor, and the metal ions are deposited on the neck edge of the gums, which makes the gums black, and the neck edge of the porcelain teeth is black, which affects the appearance. In order to reduce costs, some bad dental clinics or processing plants use industrial nickel-chromium alloy to replace medical nickel-chromium alloy, industrial nickel-cadmium alloy contains harmful impurities such as beryllium, and nickel-chromium porcelain beryllium has a carcinogenic effect on the human body, and it is strictly forbidden to use it on the human body.

At present, there are rumors that "nickel-chromium porcelain teeth cause kidney disease", and of course, dentists are negative.

In a pathology report published in the American Journal of Nephrology in May 1985, Dr. Franklin G. Strauss of the University of California, Los Angeles, and David W. Eggleston, an associate professor at the UCLA School of Dentistry, reported that a female patient's symptoms were relieved after removal of the porcelain tooth, which caused occult blood and protein in the urine due to the presence of nickel-chromium porcelain teeth. The report also said that science needs to be rigorously based, and one case is not enough to conclude the following conclusions, but only for relevant personnel to use as a reference.

Remove the porcelain teeth that are replaced by ***, and don't wait until the harm to the body is revealed. Nickel is a carcinogenic substance, and foreigners have long abandoned it. As long as many of us are poor, our lives are worthless.

Most dentists won't say that because that's the bulk of their money. There are a few who retort that allergies are a minority, yes, that the populous countries don't care about these few, but for each minority, the body is all they have. Damn, money is fate.

Nickel-chromium porcelain teeth: nickel-chromium alloy is corrosion-resistant, inexpensive, and is currently the most porcelain tooth made in China. Medical nickel-cadmium alloy is mainly composed of nickel, chromium and a small amount of metal elements that are harmless to the human body, and the adverse effects of nickel-chromium alloy on the human body are mainly caused by nickel.

Its advantage is that the cost is low, and the disadvantage is that the edge is slightly poor, and the contact with the gum is prone to a blue and gray line, which slightly affects the appearance, and occasionally there is a porcelain collapse phenomenon.

Cobalt-chrome porcelain teeth: Cobalt-chrome porcelain teeth--- an alternative to nickel-chromium porcelain teeth. It is mainly developed for the toxicity of nickel and beryllium, and its biocompatibility is better than that of nickel-chromium alloy, which is not easy to be allergic and corrosion-resistant.

The problem of black line gingiva is significantly better than that of nichrome porcelain teeth, but there are still a very small number of people who still have the problem of black line gums. It is impossible to tell with the naked eye.

It is best to fill it directly with cobalt chromium.

Nichrome alloy is a metal inner crown, and the outside is baked with porcelain, which is a nickel-chromium porcelain crown. It's the bottom grade, and what you did three years ago should have been nickel-chrome porcelain teeth.

The inner crown of nickel-chromium porcelain teeth is made of nickel-chromium alloy, which can cause oral allergies in some people. In addition, in the complex oral environment, ions may slowly exude from the metal parts exposed to the oral cavity, forming gray-black metallic lines on the gums, which may increase the amount of heavy metals in the human body, but it is still inconclusive whether it will cause kidney disease.

Whether there is a link between nickel-chromium porcelain teeth and kidney disease needs to be investigated. An in-depth examination of the patient is required, as well as a relevant medical history; In addition, the specific composition of porcelain teeth and their toxicity also need to be studied.

Therefore, there is no accurate conclusion at present, and it cannot be said that nickel-chromium porcelain teeth are harmful to the kidneys.
