Porcelain and all-ceramic teeth have their own advantages and disadvantages, there is no such thing as which is better.
1. Porcelain teeth: composed of an inner metal layer and an outer porcelain layer. Porcelain restorations have the advantage of restoring ideal tooth form and function, with the aesthetics of porcelain and the strength of metal. However, some patients will have metal allergy, which will affect the MRI during radiological examination.
2. All-ceramic teeth: covering all surfaces of natural tooth crowns, restorations that do not contain metal inner crowns. The biggest advantage of all-ceramic teeth is aesthetics, because it is translucent, so similar to natural teeth. All-ceramic material is non-toxic, stable performance, high surface finish, strong and wear-resistant, will not affect the MRI and other imaging tests, but need to grind down the tooth tissue is relatively more.
Patients should have their porcelain or all-ceramic teeth implanted in a regular hospital under the guidance of a professional doctor to avoid any danger.
