Why Did You Choose Synthetic Resin Acrylic Teeth?

Resin teeth, mainly made of methyl methacrylate. Its hardness is moderate, its shape and color are similar to natural teeth, it is not easy to be broken, and it is well combined with the base material. It is very convenient to grind and modify the anatomy and polishing.

In the process of communicating resin teeth with doctors, many doctors ask, How hard is this tooth? Is it hard enough? It seems that if the hardness is not high, it is not a good tooth, or the hardness is not high or it is not wearable.

First of all, whether it is a good denture index: realistic, hardness, wear resistance, dye resistance, occlusion, etc.; in general, the occlusal relationship of dentures produced by regular manufacturers is qualified, because once the mold scale is used, If the bite relationship is not good, it will cause more damage to the manufacturer; for the realistic features, it is generally determined by the denture layer color, the higher the layer color is, the more realistic; for the hardness, the hardness of the resin teeth of all brands currently on the market is Standardized. Therefore, the selection of resin teeth is mainly based on the wear resistance and dye resistance.

To understand the wear resistance of resin teeth, the relationship between hardness and wear resistance must first be solved. The average person thinks that the hardness is equal to the wear resistance, as long as the hardness is high and the wear resistance will be high; this is not the case. The reason is very simple, the hardness of steel is high, but as the brake pads of the car, the rubber material is used; after the cement and the sand become the concrete, the hardness is much improved, but when the floor is smoothed, the pure cement is used. Because pure cement has higher wear resistance. For dentures with high hardness, the wear resistance will be improved, but if the hardness is improved by using different material principles, the wear resistance may not be improved. Therefore, what we are looking for is a denture with high wear resistance, not a denture with high hardness.

Regarding the dye resistance of the resin tooth, it is mainly related to the material used for the resin tooth containing no inorganic filler. So we need to understand how the resin teeth are classified from the material aspect. From the basic raw materials, resin teeth can be divided into two categories: one is a synthetic resin tooth containing an inorganic filler, and the other is a synthetic resin tooth containing no inorganic filler. Resin teeth of these two types of materials may be separated into new categories due to differences in structure or molecular weight.

Resin teeth containing inorganic fillers have high hardness, but the dye resistance is significantly reduced. Why is it important to contain anti-staining properties for dentures? Resin teeth containing inorganic fillers, equivalent to pure resin materials contain some small particles, there are many gaps around these small particles, especially after the occlusal surface after grinding, after the small particles are exposed, on the one hand, the polishing position is polished. If it is not bright, on the one hand, the position of the grinding will be colored soon.

In summary, when the inorganic material is contained in the resin material, the resin teeth hardness performance is greatly improved, but the abrasion resistance and the dye resistance are remarkably lowered. Therefore, if we pursue high hardness, we must lose the need for wear and anti-staining.
