The manufacturing process requirements for a perfectly colored denture are very high. It requires an experienced engraver to carve out the teeth. It also needs a master who can color and color the porcelain teeth. It can be made after baking. These processes are very time-consuming, so many people who need dental implants, after the dentist's diagnosis, they have to wait at least half a month, and at most, they need to wait about a month before they can perform dental implants.

However, technology is progressing very fast now. Many technological processes can be completely replaced by machines, and the accuracy of the machines will be higher. However, there are still some crafts machines that cannot be made, and they still need to be made by hand with rich experience.

The principle of making porcelain teeth, which is very popular at present, is actually very simple. The raw material of porcelain teeth is zirconia. First, it needs to be carved into the shape of a tooth, which can be a whole tooth, or a crown, a bridge, and other different shapes. However, the engraved zirconia is still raw material at this time, and the next steps will be crucial. Non-professionals cannot operate it, and a dental technician is required to perform the operation in the laboratory.

Dental technicians will sinter the carved zirconia teeth, commonly known as porcelain teeth, which is actually similar to the manufacturing principle of ceramics. This sintering work requires professional dental equipment. It is a dental sintering furnace, also called a zirconia sintering furnace. There are many types of sintering furnaces, including industrial furnaces and laboratory furnaces. The furnace we mentioned here belongs to laboratory furnaces. The dental furnace has small volume, precise temperature control, good heat preservation effect, fast heating rate, high firing efficiency, and the highest temperature in the sintering process reaches 1700°C, so the price of the sintering furnace is relatively expensive. Because of the high temperature, users need to pay attention to safety when operating.

There are also different types of dental sintering furnaces. The ordinary sintering furnace takes up to 8 hours to sinter zirconia dentures, so dental technicians will not only sinter one tooth for you at a time. However, with the advancement of technology, the rapid sintering furnace has appeared. This furnace is now more and more widely used in the market, because human energy is limited, and time is equal to money. Therefore, powerful dental laboratories are basically using new fast sintering furnaces. Whether it is a new type of rapid sintering furnace or a traditional ordinary furnace, the working principle is the same. The heating elements inside the dental furnace are all heated electrically to increase the temperature inside the dental furnace. The temperature of sintered zirconia is generally 1550°C, and special circumstances are temporarily unknown. The high temperature promotes the crystallization of zirconia and the phase change to increase its physical hardness. The zirconia denture will shrink when it is sintered. The specific shrinkage ratio is generally indicated on the zirconia, and these details are very clear to the dental technician.

Porcelain teeth are finished after sintering, but the sintered dentures have no luster and look rough. Therefore, it needs to be colored and then baked. This process requires another professional dental equipment called a porcelain furnace. The operation of the porcelain furnace is more elaborate than the sintering furnace, and the baking process is also stricter than the sintering process. Porcelain masters need a wealth of experience to make a denture the same as a real tooth. First, you need to color the sintered porcelain teeth. After the coloring step is completed, the baking effect can be achieved. The porcelain furnace needs to be kept in a vacuum state, so the porcelain furnace needs to have a good sealing effect. Because there are many manufacturers of zirconia, each has a different ratio of zirconia, so different brands of zirconia need to be set up in different procedures. Zetin dental zirconia porcelain furnace has 40 built-in programs, and users can also set up their own programs according to their actual needs. After coloring and baking, the color of dentures is similar to that of real teeth. However, there is a new type of color 3D multilayer zirconia block. After such a zirconia block is engraved by an engraving machine, it will be sintered directly to be similar to the color of real teeth. Using this new type of zirconia block allows dental technicians, dentists, and People who need dental implants save a lot of time.

This is how a perfect porcelain tooth is born.
