Experts said, also called the tooth of the porcelain fused to metal crown. [the first brand of porcelain teeth caused by Li Po dental configuration Mr. Huang telephone: 0755-27797118] it is used first, alloy metal base, covering similar to that of natural teeth low fusing porcelain powder on the surface, in a vacuum high-temperature ceramic sintering furnace fused into. Morphology and function it can restore the tooth bending strength, color, and appearance of realistic, smooth surface, strong wear resistance can not be deformed, color stability. Porcelain restoration success should be realistic shape, color stability, acid and alkali resistance, is a permanent prosthesis.

Porcelain dental materials have the following three:

1, non noble metal porcelain teeth. Is made of Ni Cr alloy metal crown temperature porcelain, its price is relatively low, so it is widely used in China. However, this kind of porcelain teeth has the following disadvantages: marginal sealing difference; biocompatibility with human body, some patients for some time to wear neck margin of the gum tissue will appear "black", even in foreign countries anaphylaxis such porcelain teeth triggered by the case report; moreover, due to the mismatch in the coefficients of Ni Cr alloy ceramic thermal expansion, so the clinical more prone to the phenomenon of collapsing porcelain.

2, the noble metal porcelain. It is in the League more than 80% golden, alloy adding trace elements such as platinum or rhodium. Although the price is higher, but there are significant advantages: because the alloy copings reflects the natural tooth shine in the sun, and good biocompatibility, safe use, density is high, a combination of porcelain and metal is very good, very few collapse porcelain situation. It is widely used in Europe and the United states.

3, all porcelain teeth. As the name suggests is a non pure ceramic porcelain technology of metal inner crown. Because there is no metal limits, teeth levels and color to the greatest extent reflected, so all ceramic dental appearance effect is best; and porcelain is safe to human body, no stimulation. But because of the influence of the strength of porcelain, commonly used for anterior teeth porcelain veneer, inlay manufacturing single crown body and anterior teeth porcelain.

Above is the detailed introduction to the tooth of the porcelain material, through the understanding of the porcelain materials mainly three, non noble metal porcelain teeth, porcelain and porcelain teeth, porcelain teeth of course in the choice of when we should start from the aspects of its own, or to a regular dental hospital detailed consultation, in order to select the most suitable for porcelain teeth themselves.
