Dental crown materials are divided into three categories: cast metal crown, porcelain crown and all-ceramic crown.
1. Cast metal crown: good retention and mechanical strength, ideal long-term use effect, relatively cheap price, but poor aesthetics, and can not be used for anterior teeth and premolars.
2. Porcelain crown: it is a full crown restoration formed by melting porcelain powder on the internal metal layer and sintering at high temperature. It has the advantages of mechanical strength of metal crown and aesthetic appearance of all-ceramic crown, but it is easy to collapse after long-term use, and the aesthetic effect is not as good as that of all-ceramic crown, and more tooth tissue is removed.
Third, all-ceramic crown: the biggest advantage is that the aesthetic effect is better, the translucency is closer to natural teeth, and it is non-toxic. Polycrystalline ceramics have good strength, but the price is higher.
