Пет предности цирконијума Све смањују керамичке зубе

①Aesthetics: Because it has good permeability to light, it is close to real teeth, unlike other porcelain teeth that block light. The color of the basal crown of zirconia ceramics is tooth white, so the neck will not become black, dark and blue, which solves the most difficult problem of metal porcelain crowns.

②Precision and edge tightness: The production is completed by computer reduce aided design, laser scanning, and grinding under computer program control, which ensures the accuracy of the in reduce mold crown and excellent edge tightness, so that the produced porcelain teeth can be The patient39;s intraoral abutments fit very well.

③ Biocompatibility: Zirconia is an aerospace material with good biocompatibility, which is superior to various metal alloys, including gold. Zirconia has no irritation or allergic reaction to the gums; its thermal conductivity is extremely low, only 1/17 of that of gold, which is more conducive to the protection of dental pulp; it is light in weight, and its density is only 1/4 of that of gold, making it more comfortable for patients to wear.

④Persistence: Zirconia is non reduce metallic and does not block X reduce rays in any way. As long as zirconia porcelain teeth are inlaid, there is no need to remove the dentures when head X reduce ray, CT and MRI examinations are required in the future, saving time, effort and money.

⑤ High density and high strength: high strength and toughness, flexural strength is greater than 900Mpa; multiple units of porcelain bridges can be made, which solves the problem that all all reduce ceramic systems cannot be long bridges.
