Metal porcelain teeth are divided into two layers, the inner layer is a layer of metal and the outer layer is porcelain teeth. All-ceramic porcelain teeth have no internal metal and are completely porcelain. Metal porcelain teeth can be roughly divided into nickel-chromium porcelain teeth, cobalt-chromium porcelain teeth, titanium alloy porcelain teeth and pure titanium porcelain teeth according to the different internal metal materials.
At present, the material of all-ceramic porcelain teeth is zirconium dioxide. According to the different processing technology, the cost of common zirconia is about 1000 yuan, the cost of imported zirconia is about 2000 yuan, and the cost of automatic aided design production is about 3000-5000 yuan.
Extended data:
trait
1, natural color. Compared with traditional porcelain teeth, zirconia porcelain teeth are naturally bright and clean in color, realistic in appearance and strong in transparency.
2. Good biocompatibility. No irritation to gums, no allergic reaction, and no gingival black line. It is very suitable for oral cavity, and avoids the adverse stimulation such as allergy, irritation and corrosion caused by traditional metal porcelain teeth in oral cavity.
3. The tooth has high strength and hardness. Unique fracture resistance and strong post-folding curing performance make teeth stronger.
4. High precision and good edge sealing. Zirconia porcelain teeth ensure the accuracy of the in-mold crown and excellent edge sealing, so that the porcelain teeth are very close to the abutment teeth in the patient's mouth.
