As an ideal tooth whitening restoration method, tooth veneer has been favored by many beauty lovers. So what are the types of veneers? Tooth veneers can be divided into hard veneers, resin veneers and porcelain veneers according to materials. (1) Nano-resin veneer is to cement polymer composite resin on the ground tooth surface and carefully carve it into an ideal tooth shape. Nano-resin has natural tooth color, which can effectively cover the discolored tooth color, obtain beautiful tooth color, shape easily and achieve ideal tooth shape. The operation time can be completed at one time. Veneering is to evenly grind off a layer on the lip surface of the tooth, make a good film pressing, and then paste it on the tooth with a special dental porcelain material containing resin. Hard veneer has the characteristics of high hardness, no discoloration, long service life, beautiful appearance, good wear resistance and smoothness, and the price is moderate, so it is an ideal choice for veneer repair. ③ Porcelain veneer: A layer of tooth lip surface is evenly ground off, a model is made, then the dental porcelain material is sintered under vacuum pressure, and then it is pasted on the tooth, so that the color index of the tooth can be accurately controlled. Porcelain veneer has strong light transmission, very good cosmetic effect and looks very natural, which can achieve almost perfect effect. Wear resistance is similar to that of teeth, which requires high level of doctors, relatively many surgical steps and is relatively expensive.
