As we all know, porcelain teeth is a very good and very welcomed by everyone in the dental restoration techniques. The best porcelain teeth porcelain teeth to the number, while Germany zirconia all-ceramic dental maybe we do not understand, zirconia is a high temperature, wear resistance, corrosion resistance inorganic non-metallic materials, the chemical stability, corrosion resistance, oxidation resistance, thermal shock, non-volatile, non-polluting, heat is used to shield the space shuttle, Porsche brake disc such as the production, domestic and Amy was recognized as the "US teeth" Preferred . A good aesthetic effect. Zirconia good permeability to light, close to real teeth. Since the end of the tooth crown color is white, not black neck after insert darken blue. Second, high precision and edge adhesion. Through computer-aided design, laser scanning, and then controlled by a computer program produced finely ground, it guarantees the accuracy of crown molding and excellent edge confined, so that made out of porcelain teeth and the mouth of the patient abutments very fit, greatly reducing the incidence of post-repair root inflammation. Third, good biocompatibility. Zirconium dioxide is a very good high-tech biological material, biocompatibility, superior various metal alloys, including gold. And gums no stimulation, no allergic, non-corrosive effect is suitable for oral. Low thermal conductivity, only one seventeenth of gold, more conducive to the protection of the pulp. Fourth, safe and reliable. Zirconium dioxide oxidation does not occur, not only to avoid metal corrosion, more resistant metal odor generation. In addition, the non-metallic zirconium dioxide on the X-ray unimpeded shot, as long as the insert zirconia porcelain teeth, skull x-ray in the future need, do not need to tear down dentures CT, MRI examination, save a lot of hassle. Fifth, high density and high strength. ① more than 900Mpa flexural strength, can withstand at least 50 kilograms of tension; ② unique resistance to cracking and fracture toughness after the curing properties; ③ can create multiple unit porcelain bridge to solve the all-ceramic system can not do Longbridge problem.
