Introduction of barium chrome porcelain teeth, cobalt chrome porcelain teeth

It's not barium chrome, it's bego (Chinese pronounced like Berg) porcelain, a company in Germany.

In fact, the main ingredient is cobalt chromium, which is cobalt chromium porcelain teeth, which is not a kind of cobalt chromium. There is no big difference from the usual cobalt-chrome porcelain. To give you an example, although Mengniu milk and Yili milk are not the same kind of commodity, they are all milk, basically there is no difference, the difference is some trace additions, packaging or something.

At present, there is no such thing as a porcelain that uses barium as the main ingredient.

The doctor really knows how to engage in gimmicks, not to say cobalt chrome porcelain, but to bego porcelain.

It's cobalt-chromium alloy, it's generally better for the gums and roots to be all-porcelain, the kind without metal, you ask your doctor to see if there is, please choose a regular hospital or a professional dental clinic to see your teeth, refuse to be a bad doctor in a small clinic, if you have any questions, you can ask me directly 43054325

Cobalt-chromium alloy was first used to make artificial joints with outstanding biocompatibility, and has been widely used in the field of oral cavity. It is suitable for the restoration of most teeth, especially for fixed restorations such as posterior fixed bridges.

All-ceramic tooth is a general term for restorations without metal substrates, which are divided into many kinds according to the crystal structure or production process, and the full name of cast porcelain is hot-pressed casting glass ceramics, which is classified according to the production process, and has developed from empress1 and empress2 to IPS press, and the strength has been improved to a certain extent. The advantage of cast porcelain is that it has good light transmittance, and the prosthesis made is beautiful and realistic, with a sense of hierarchy, which is the first choice for cosmetic restoration of anterior teeth. The latest HT porcelain blocks are available in 16 colours and can be used for single crown restorations of posterior teeth with only stained surfaces.

However, due to the lack of strength of cast porcelain, it cannot be used for the production of posterior tooth fixing bridges.

The advantage of zirconia all-ceramic teeth is that their base is a zirconia ceramic material. Zirconia ceramics are the ceramic materials with the best mechanical properties such as strength and fracture toughness in the oral field, which can ensure that the restorations have sufficient strength to bear the occlusal force, and can be widely used in the restoration of anterior and posterior crowns and bridges. However, zirconia ceramics have poor light transmittance and single color, so it is necessary to improve the aesthetics of the restoration through surface decoration porcelain, which has a color shielding effect on the discolored abutment tooth and metal pile core, but the final layering of the restoration is not as good as that of the cast porcelain restoration.

In addition, many foreign studies believe that the binding force of zirconia substrate and decorative porcelain is a difficult problem, and the extracorporeal bypass loading test and clinical follow-up have shown that the failure of zirconia all-ceramic restorations is mostly due to the disintegration and cracking of the decorative porcelain layer.
