The hazards of nickel-chromium porcelain teeth

Dentures are very common. For some people with bad teeth, if they need to have their teeth extracted, they need to use dentures instead. There are many types of dentures, and you cannot choose them casually. Many people choose dentures mainly based on cheap ones, which will cause some harm to human health. What are the hazards of nickel-chromium porcelain teeth? There are also many aspects.

Many people are not very clear about the hazards of nickel-chromium porcelain teeth, so when choosing nickel-chromium porcelain teeth, you must first understand it so that you can make the right choice and avoid harm to yourself.

The hazards of nickel-chromium porcelain teeth:

Nickel-chromium alloy porcelain teeth are widely used because of their low price. More than 50% of patients who undergo porcelain teeth choose this type of porcelain teeth. Clinically, it has been found that some people are allergic to nickel, which can cause inflammation of the skin and mucous membranes. As for whether nickel-chromium alloy porcelain teeth can cause kidney disease, "it has not been recorded in textbooks and literature", so it is difficult to say, and the netizen's experience may be accidental. A kidney expert from the Fuzhou General Hospital of the Nanjing Military Region believes that if there are too many trace elements in the human body, it may lead to kidney disease. Excessive amounts of heavy metals, such as silver and mercury, have a direct impact on kidney function. "But this netizen only used it locally, so it's hard to conclude that it was caused by porcelain teeth."

In sharp contrast, the director of a dental hospital in Beijing strongly recommends "eliminating the use of nickel-chromium porcelain teeth" - because nickel-chromium porcelain teeth are highly toxic and can cause an increase in nickel in the human body. The director told reporters that a few days ago a patient who had nickel-chromium porcelain teeth installed came to the hospital for treatment and recently developed symptoms such as urticaria, herpes, lichen, and allergic rhinitis. Trace element determination showed that the nickel content in the patient's urine exceeded the standard by 13 times. At the same time, the patient had metal precipitation in his mouth and gingival erosion.

Nickel-chromium porcelain teeth are used. In Japan, Germany and other places, nickel-chromium alloys are banned in dentistry. The installed dentures are at least gold and other precious metal porcelain teeth, at worst cobalt-chromium teeth. A scholar at West China University of Medical Sciences who has been engaged in oral biomaterials research for a long time also agrees with this view. He said that nickel-chromium alloy porcelain teeth are rarely used in the West because they are not aesthetically pleasing and once the porcelain falls off, heavy metal ions can be released, becoming toxic and possibly carcinogenic. Therefore, all-ceramic teeth have been used all over the world. They are made of zirconium dioxide, have good biocompatibility, are non-irritating to the gums and have no allergic reactions, and are superior to various metal alloys such as gold. There is also the issue of silver amalgam. An expert panel composed of the US Department of Health, the European Commission, and the World Health Organization (WHO) believes that except for rare allergic reactions, there is no reliable evidence to prove a causal relationship between silver amalgam and adverse health effects. However, some governments still recommend not using silver amalgam for certain patients.

Through the above introduction, we have a good understanding of the hazards of nickel-chromium porcelain teeth. When choosing such dentures, we should do so appropriately. However, it should be noted that if economic conditions permit, try to avoid choosing this type of denture. Although it is cheaper, it can cause great harm to the human body.
