Porcelain teeth, the full name of porcelain fused to metal restorations, are restorations made by melting ceramic powder and combining it with specially treated metal surfaces under vacuum conditions with the help of high temperature. Its aesthetics and biocompatibility are irreplaceable by other prostheses, and it is the most ideal prosthesis so far.
What are porcelain teeth?
It is the most ideal and popular prosthesis in China at present. 1950 successfully developed in the United States. Its composition is made of alloy as inner layer, covered with porcelain powder similar to natural teeth, and sintered and baked in vacuum. It has both the strength of metal and the beauty of porcelain, can correctly restore the morphological function of teeth, has strong disassembly resistance, high corrosion resistance, stable color, beautiful appearance and smooth surface. This is a lifelong repair, truly realized. "
2. Objects suitable for making porcelain.
The age of porcelain teeth is about 20-60 years old. Before making porcelain teeth, it is necessary to grind the original teeth very thin. Because of the incomplete development of juvenile permanent teeth, the pulp cavity is wide, which is easy to hurt the pulp. Old people, because it involves gingival atrophy, loose teeth, general condition, psychological factors and so on. It depends on the specific situation, some patients are not suitable for severe smear, bite the bullet. Of course, it depends on the specific situation.
3, the impact of porcelain teeth on the service life and firmness of teeth To make porcelain teeth, you must grind your teeth very thin. Some people worry about what will happen after tooth restoration. Generally speaking, after small teeth are restored, they will be sensitive to the cold, heat, acid and sweetness of the outside world. Don't worry, the doctor will give you a temporary crown to protect your teeth. After the porcelain teeth are finished, remove the temporary crown, replace them with porcelain teeth, and add bonding materials for isolation. On the contrary, switching to porcelain teeth will have a good "protection" effect on your teeth, and you no longer have to worry about "rotten holes" in your teeth. A porcelain tooth that has been strictly, standardized, correctly operated, designed and manufactured by a regular doctor can be used in the mouth for a long time. According to research, about 65% of common alloy porcelain can be used for more than 20 years, which requires patients' own care. If you don't brush your teeth and chew casually, it will greatly reduce its service life. When you brush your teeth carefully, go to the hospital to clean your teeth regularly, stay healthy, avoid eating hard food (normal use) and make high-grade and expensive alloy porcelain teeth, then its life can reach its life. A good porcelain tooth depends on the standardized operation of clinical engineers, correct design, professional restoration theory and close cooperation of technicians, otherwise it is difficult to achieve the ideal restoration effect. At present, all primary hospitals in China have porcelain teeth. But not everyone can do it well. Some teeth are too small (small and pointed) and the defects are too large. In addition, when the doctor operates, the aggregation is too large (normal 2-5). In this case, the porcelain teeth will adhere and fall off in a short time, leading to irreversible restoration. On the contrary, if the indications are carefully grasped, corresponding measures should be taken to apply high-performance adhesives under normal operation.
