Porcelain teeth and all-porcelain teeth, are restorative treatment after the occurrence of tooth loss. All-porcelain teeth have obvious advantages over porcelain teeth, which are generally recommended clinically, with the following differences: 1, all-porcelain teeth do not contain metal inside, which will not have consequences on magnetic resonance, while porcelain teeth have metal components inside, which can easily cause abnormal magnetic resonance imaging. 2, porcelain teeth have metal elements inside that may penetrate into the gums, causing discoloration of the gum tissue and affecting the aesthetics. 3, porcelain teeth inside the metal elements with the extension of time, will also penetrate into the porcelain interior, so that the porcelain teeth color change. All-porcelain teeth do not contain metal, will not cause the gums to change the color of the consequences, but also not with the extension of the porcelain color change, so all-porcelain teeth are relatively stable. However, in terms of price, all-porcelain teeth will generally be more expensive than porcelain teeth.
