Little radiation Medical zirconia is cleaned and processed, leaving a small amount of alpha ray residue in zirconium, which penetrates to a small depth of only 60 microns. High density, high strength, metal-free inner crown Zirconia has unique resistance to cracking and strong curing performance after cracking. It can be used to make more than 6 units of ceramic bridges. Although there is no metal support, it has high strength, and its refractive index is basically close to that of natural teeth, with dense edges and high precision, and has excellent aesthetic effects: Zirconia ceramics are usually yttrium-stabilized zirconia ceramics with high flexural strength. Compared with other all-ceramic restoration materials, the strength advantage of zirconium dioxide material allows doctors not to rub the patient's real teeth too much. Excellent aesthetic effect Zirconia all-ceramic teeth have a realistic and beautiful appearance, solid and wear-resistant, similar in color
