The star's perfect teeth are obvious to all. Why are the stars' teeth so beautiful? The oral experts of Changzhou Shuguang Hospital Digital Oral Center told us that the secret lies in. ? The stomatologist of Changzhou Shuguang Hospital Digital Stomatology Center gave the following answer: 1. Realistic color: the light transmission and refraction of all-ceramic teeth are closer to natural teeth than metal porcelain teeth, and the layers and colors are realistic, especially under strong light (stage lights and sunshine), so there is no longer the embarrassment of "green teeth shining". 2. Safety: because it does not contain metal, it will not affect the test results of special medical instruments such as nuclear magnetic resonance and vibration, and it is safe and reliable. In addition, all-ceramic teeth have fewer molars, no irritation to gums, and can retain their own tooth tissue to a greater extent. 3. Good biocompatibility: Many people are allergic to metals in porcelain teeth. In the latest CRA clinical evaluation report published by the American Association for Clinical Research, it is concluded that all-ceramic crowns can eliminate metal allergic reactions, have good cosmetic repair effects, and completely avoid some patients' allergic reactions to metals. 4. Beautiful and generous: it can provide beautiful, natural and active restoration effect, and is suitable for patients with gingival recession, blue gums, swollen gums, poor color and porcelain collapse after fixed denture, and will not make your gums appear black lines, swollen gums and bleeding. 5, durable: many people will literally understand all-ceramic teeth, like porcelain, it will break when touched. In fact, the hardness of all-ceramic is similar to that of enamel, so don't worry about it breaking teeth. It has the compressive strength comparable to that of metal porcelain teeth, and it will not wear the natural teeth of human body and is durable.
