1 The non-precious metal porcelain tooth is made of high temperature porcelain made of nickel-chromium alloy, and its price is relatively low.
2 This kind of porcelain tooth has the following disadvantage: the edge compactness is poor.
3 The biocompatibility with human body is poor, some beauty lovers wear it for a period of time, the gingival tissue at the neck margin will appear "black line".
4 There are even cases of allergic reaction caused by porcelain teeth in the world.
5 Due to the mismatch of thermal expansion coefficient between Ni-Cr alloy and porcelain, it is easy to disintegrate porcelain in clinic.
It is widely used in clinic because of its low price. At present, about 70% of nickel and 30% of chromium in china are nickel, the rest are ruthenium, tin, manganese and so on.
