What material are resin teeth made of?
Mainly made of methyl methacrylate. Its hardness is moderate, its shape and color are similar to natural teeth, it is not easy to crack, it is well combined with base material, and it is very convenient to polish, modify and polish. The color is yellow, and 1 to No.6 are slightly red, which are from light to dark according to the color number order. Resin teeth can be divided into two types according to the basic raw materials: one is synthetic resin teeth with inorganic fillers, and the other is synthetic resin teeth without inorganic fillers. The resin teeth of these two materials may be divided into some new categories because of their different structures or molecular weights.

Resin teeth containing inorganic fillers have high hardness, but their dyeing resistance is obviously reduced. Why is it important to contain inorganic fillers in the stain resistance of dentures? Resin teeth containing inorganic fillers are equivalent to pure resin materials containing some small particles, and there are many gaps around these small particles, especially on the occlusal surface after molars. After small particles are exposed, on the one hand, the grinding position is not polished, on the other hand, the grinding position will soon be colored.

When the resin material contains inorganic filler, the hardness is greatly improved, but the wear resistance and dyeing resistance are obviously reduced. Therefore, if we blindly pursue high hardness, we will inevitably lose the demand for wear resistance and dyeing resistance.
