Co Cr porcelain teeth you know about

Cr porcelain teeth advantage is the stability of metal with a strong, high corrosion resistance under normal circumstances will not be any black gums or bleeding gums phenomenon. With precious metal and porcelain dental all-ceramic tooth compared to cobalt-chromium porcelain teeth on the lower costs significantly. And compared with the Ni-Cr porcelain teeth, then porcelain dental cobalt-chromium and relatively safe.

Co-Cr porcelain teeth experts said corrosion in the oral cavity: non-precious metal alloy corrosion performance of the same precious metal alloys are fundamentally different. Precious metal alloy as its main ingredient-dimensional metals gold, platinum, or palladium and silver, these metals form a self-passivating Dental Supplies oxide layer, it can largely prevent corrosion. This is also reflected in the aspects of ion release.

In the precious metal alloys, primarily minor components, especially antioxidants and zinc as adhesive, the phenomenon will be dissolved, and non-precious metal alloy corrosion is the main component of cobalt by the decision. According to German Industrial Standard DIN EN ISO10271 requirements made of corrosion point of view, the lowest gold alloy ion release, followed in turn titanium, cobalt chromium alloys and nickel-chromium alloy.

Co-Cr porcelain teeth is typical of non-precious porcelain teeth. Then the composition of Co-Cr porcelain teeth is what constitutes it? Is generally less than 25% chromium, less than 4% molybdenum, cobalt, nickel, chromium, three kinds of add up to less than 85%.

Nickel-chromium alloy and dental porcelain compared to cobalt-chromium alloy, easy casting, more economical, but its physical properties and corrosion resistance as well cobalt-chromium alloy. When out of the thermal environment, for example, when the porcelain, nickel-chromium alloy may change the Select the appropriate orthodontic treatment time physical properties of the alloy becomes more fragile, not suitable for long bridges. This point, cobalt-chromium alloy resistance to heat treatment is far superior to nickel-chromium alloy.

In order to maintain oral hygiene, and after eating before going to sleep should be carefully mouthwash, mouthwash should not be too impatient, go slowly into the spit mouthwash, which can prevent the wound to bacterial infection. In addition, during wound healing, patients need treatment with medication, must be strictly in accordance with physician's orders medication. Because of the damage caused by tooth extraction, can drink vitamin-rich fruit juice, to promote wound healing.
