Love healthy dental all-ceramic tooth can be divided into zirconia all-ceramic tooth, two alumina ceramic dental cast of all-ceramic dental three categories. Because of the choice of different materials, the full three types of porcelain teeth each have their own advantages.
1. Zirconia all-ceramic dental
Zirconia all-ceramic tooth is a full-porcelain teeth produced by the slip casting method, is coated zirconia refractory tooth model slip in the high temperature so that the molding. It is a very good high-tech biomaterials, biocompatibility, and dental equipment superior to a variety of metal alloys, including gold. Zirconia gum irritation, allergic reaction is very suitable for oral. The thermal conductivity is very low, only gold seventeenth, more conducive to the protection of the pulp. Light weight, density, only a quarter of the gold, the patient more comfortable to wear.
2. Casting all porcelain teeth
After casting all porcelain teeth to make the appropriate tooth model with wax, and then proceed to a high temperature wax steps, and finally will make good porcelain block melt through pressure cast into the circle, all-ceramic dental finished product is complete. The cast of all-ceramic teeth are beautiful, good translucency, refraction similar to the enamel, dental cosmetic results closer to the natural teeth.
3. Two alumina ceramic dental
High strength and toughness of alumina ceramic teeth has been proven successfully used the shuttle's heat shield, the Porsche brake disc and How corrections buck teeth man-made transmission with the much larger than the other known non-metallic ceramic, it's tough.
