What kinds of materials are there for dental implants?

Dentures are also called dentures. Dentures need dental materials. Presumably all customers who want to make dentures want to know about dental materials. Below, the experts will introduce it. According to experts, the principle of dental implant requires that the materials are non-toxic, tough, easy to operate, not rare, strong, easy to clean and corrosion-resistant, which is the basis for choosing dental implant materials. Dental materials generally include the following categories: 1, nickel-chromium alloy: an alloy widely used in China at present, which has good bonding force between metal and porcelain and stable long-term use effect. The disadvantage is that due to the active chemical properties of metals, long-term use in the mouth will lead to free metal components, leading to black lines in the gums, so it will affect the aesthetic effect when used in anterior teeth restoration. In addition, some people are allergic to metallic nickel, so be careful of those who are known to be allergic to nickel. The price is also the cheapest. 2. Resin materials: The early resin materials were poor, and now many imported or specially processed resin materials are not worse than other materials in quality. The biggest advantage of resin material is its cheapness. The disadvantage is that it is easy to fall off and crack, and its service life is not long, usually 3-5 years. When manufacturing, the thickness of the base will be deliberately increased, resulting in poor adaptability of patients. 3. Co-Cr alloy: strong corrosion resistance, good biocompatibility and higher price than Ni-Cr alloy. 4. Titanium alloy: containing trace titanium, it is still a nickel-based alloy. High strength, corrosion resistance and oxidation resistance meet the basic clinical requirements. 5. Pure titanium alloy: The disadvantage of pure titanium material is its high price. The advantages are that the whole denture is thinner and lighter than other metal alloys, with high patient adaptability, good biocompatibility and no side effects on human body. 6. Precious metal alloy: it has excellent corrosion resistance, oxidation resistance, good adhesion and biocompatibility, and is an ideal metal full crown restoration material with relatively high price. 7. All-ceramic material: It has the best biocompatibility, no irritation to gums and no allergic reaction. It belongs to metal-free repair and has no effect on the results of NMR examination. The disadvantage is that some materials are not suitable for all teeth because of their different strengths, and some special processing techniques lead to relatively high prices.
