zirconia all-ceramic dental Scope fine list
Zirconia all-ceramic dental restoration is porcelain teeth in an excellent view of zirconia all-ceramic dental advantages, many of my friends want to do U.S. dental zirconia all-ceramic dental
. But as a means of repair, zirconia all-ceramic dental also has strict scope, then zirconia all-ceramic dental scope, what does?
Zirconia is a high dental x ray unit temperature, wear-resistant, corrosion-resistant inorganic non-metallic materials. Its melting point up to 2700 degrees Celsius, the best performance is the nature of fire
One of the materials. Its thermal conductivity is poor, but the conductivity is very strong, strong ability to resist, even if heated to over 1900 degrees Celsius will not work with molten aluminum, iron, nickel
, Platinum and other metals, silicates, and play a role in acidic slag. His toughness is much larger than other known non-metallic porcelain.
About zirconia all-ceramic dental scope, experts pointed out include the following aspects:
Discolored teeth, common yellow teeth, perfect repair tetracycline, correcting individual missing teeth, broken teeth, teeth too wide, enamel hypoplasia, malformations and other types of teeth
Branch diseases can be used zirconia all-ceramic dental.
In addition, Apex Locator zirconia all-ceramic dental appearance, the perfect solution to patients with severe tetracycline teeth beauty needs; zirconia all-ceramic dental because most prominent feature is not
Metal within the crown, so the teeth, good transparency, excellent gloss, more effective way to avoid metal allergies and other problems. In addition, he has a good enough masking capabilities, superior toughness so
