So what? I believe everyone knows it very well. Let's have a look. ? Han Chun Plastic Surgery Hospital in Meilai said that all-ceramic teeth are a new type of porcelain-fused-to-metal restorations, which are based on ordinary porcelain teeth. At present, zirconia all-ceramic teeth, cast porcelain teeth and alumina all-ceramic teeth are widely used. The following are the characteristics of our three all-ceramic dental materials. I believe you can find the answer in your mind. 1. Zirconia all-ceramic tooth material: Zirconia all-ceramic tooth is the strongest tooth restoration, and it is not easy to break when it is used to repair teeth. Secondly, it can be used to beautify and repair missing teeth, and can repair multiple teeth, that is, it can be used for continuous dental crown restoration. Zirconia all-ceramic teeth are a design that emphasizes holistic thinking, so the teeth made are realistic in appearance. Its color is perfect, and it looks like a real tooth. Zirconia all-ceramic teeth have good biocompatibility and will not cause gingival inflammation when used to repair teeth. 2. Alumina all-ceramic tooth material: it will not leave a black edge on the edge of the root and has a unique appearance. It has a translucent appearance, so its aesthetic characteristics are better. Using it to fill teeth will not cause gum inflammation. 3. Cast porcelain tooth material: Cast porcelain is not suitable for the restoration of continuous crown, but only for the restoration of single crown. It has good light transmittance and is not suitable for the restoration of severely discolored teeth. Its color is beautiful, it has excellent aesthetic characteristics and good biocompatibility, and the tooth base has no black edge, so the sealing performance of the tooth is better, so there will be no gum inflammation. ? Experts pointed out that all-ceramic teeth have the characteristics of good aesthetics, high strength, safety, non-toxicity, precision and durability, including cast porcelain, aluminum porcelain and zirconia all-ceramic teeth, among which zirconia all-ceramic teeth are the first choice. Tooth loss, tooth body defect, tooth decay, bad tooth color, irregular dentition and so on can all be repaired with all-ceramic teeth. ?
