Question 2: Is it better to use metal or all-ceramic zirconia for the whole set of teeth? Compared with metal, zirconia has the main advantages of good biocompatibility, no allergy and poor thermal conductivity, so it can protect gums, and ceramics are more beautiful, so it won't hurt people without taking them off for medical examination (such as nuclear magnetic resonance). The main famous brands are German Vilander, domestic Eltron, Edith and Jirui.
Compared with zirconium dioxide, metal teeth have better toughness and are not easy to crack when forced to bite. The main well-known brands are American Argen, Nobiline and so on.
In a word, zirconia is better for health and metal is more durable.
Question 3: Zirconia-Zirconia (ZrO2 _ 2) Composition and classification of natural zirconia mineral raw materials, mainly baddeleyite and zircon. Zirconite is a kind of igneous deep mineral with hardness of 7.5 and strong metallic luster, which can be used as raw material of ceramic glaze. It belongs to the main materials harmless to human body in modern medicine, and is mainly used for dentures or artificial joints.
Question 4: What is the difference between porcelain-fused-to-metal teeth and all-ceramic teeth? You can come to our hospital to find out that there are many kinds of porcelain teeth, such as nickel alloy porcelain teeth, cobalt-chromium porcelain teeth, zirconia all-ceramic teeth and so on. You need to choose your own porcelain teeth according to your oral conditions. Porcelain teeth are not the higher the price, only the best that suits you. Characteristics of common types of porcelain teeth. Titanium alloy porcelain teeth: due to the limitation of titanium casting technology and equipment, it is impossible to cast titanium alloy raw materials in inert gas, but titanium alloy raw materials are cast in natural air. As a result, titanium metal is oxidized and volatilized in the air. In addition, titanium itself is light in weight, so when centrifugal casting, titanium metal falls backwards and cannot enter the casting. The so-called titanium alloy porcelain teeth are all different from the standard of 6% titanium. The actual titanium content is sometimes lower than that of nickel-chromium porcelain itself. This is a kind of porcelain tooth. Nickel-chromium alloy porcelain teeth: the main components are nickel and chromium. This is also one of the types of porcelain teeth. Its cobalt content is higher than that of nickel-based alloy, generally 25%, and there are other elements such as copper, tungsten, niobium, silicon, ruthenium, aluminum and molybdenum. Because nickel can react with saliva in the mouth to generate free nickel, which accumulates on the edge of the crown and gums, thus producing a well-known black line (gray staining).
Question 5: What are the disadvantages of zirconia all-ceramic teeth? If the shortcomings of zirconia porcelain crown can be roughly summarized as three points: 1. Teeth are fragile and easier to break than porcelain crowns.
2. The zirconia crown is pure white, which is less transparent than the alumina all-ceramic crown.
3. Zirconia is semi-machined and lacks artificial originality. It can also be said that there is a little personality in modeling and edge treatment.
Question 6: How many dental implant brands are there in the United States? What's the difference between zirconium dioxide and metal? There are four kinds of dental implant systems in the United States: Biomet3i-NANOTITE, biomet3i-ostetite, Biomet3i-LTX and BICON Baikang. Generally speaking, ordinary metal porcelain teeth are cheaper than zirconia porcelain teeth. However, zirconia porcelain teeth are more transparent and realistic than ordinary metal porcelain teeth.
