What are the hazards of metal porcelain dentures

We all know that once teeth are damaged, it will have a great impact on our normal life. Sometimes we have to install dentures to ensure our normal life. However, there are many types of dentures, among which metal dentures are the most common. However, some different materials are also prone to cause certain harm to the body. Let's take a look at the hazards of metal porcelain dentures.

What are the hazards of metal porcelain dentures

Hazards of traditional species:

First of all, backward technology, easy accumulation of dirt, and black gums are one of the hazards of porcelain teeth:

The traditional metal porcelain teeth manufacturing technology is backward and the workmanship is rough. The gaps between teeth are large and dirt is easily accumulated. In addition, metal ions are deposited on the cervical margin of the gums, causing the gums to turn black and the cervical margin of the porcelain teeth to turn black, affecting the appearance of the teeth.

Secondly, the harm of porcelain teeth is that some metal porcelain teeth contain metal nickel that is harmful to human health:

Modern medicine has proven that some metal porcelain teeth contain nickel, which is allergenic and carcinogenic to the human body. It can cause mild inflammation of the gums in some people, which is harmful to the health of the gums and affects the appearance.

Finally, bad dental clinics or processing plants use industrial nickel-chromium to replace metal alloys, which is also a hazard of porcelain teeth:

In order to reduce costs, some unscrupulous dental clinics or processing plants use industrial nickel-chromium alloys instead of medical metal alloys. Industrial nickel-cadmium alloys contain harmful impurities such as beryllium, which is carcinogenic to the human body and is strictly prohibited from use on the human body.

Advantages and disadvantages of titanium alloy porcelain teeth

1. Advantages: Titanium alloy has a very good bonding strength with ceramics. Titanium alloy porcelain teeth are not easy to break and are durable. Titanium alloy has good biocompatibility and usually does not cause discoloration of surrounding tissues.

2. Disadvantages: The inner crown of the titanium alloy porcelain crown is gray metallic in color. After restoration, the titanium alloy porcelain crown will appear to have an imperceptible bluish color under special light, and its cosmetic effect is relatively poor.

Precious metal types

The representative of precious metal porcelain teeth is gold alloy porcelain teeth. The use of gold in human beauty has a long history. In ancient Egypt, "gold silk beauty" was popular because gold is more compatible with the human body. A long time ago, gold was used as a material for filling teeth and is one of the most ideal restorative materials. It has the advantages of titanium alloy, and is stronger and non-irritating. The combination of gold and porcelain is very strong, and it has better compatibility with tissues. It will not turn blue where the porcelain teeth come into contact with the gums. In addition, porcelain powder can reflect its own color on the surface of gold, making porcelain teeth more beautiful and fully meeting the requirements of cosmetic restoration.

The above is an introduction to the hazards of metal porcelain dentures. After understanding it, we know that metal dentures are also divided into different materials, and some materials may cause harm to the body. In addition, we can avoid problems with our teeth in our daily lives. We must ensure good oral hygiene and try to eat less sweet foods.
