CAD means computer-aided design; CAM means computer-aided manufacturing.

That is to say, the design and manufacture of this kind of zirconia crown are all completed by computers, except for the need for doctors to grind (prepare) teeth and finally wear teeth.

The advantages of zirconia are:

1. Zirconia is a mineral that exists as plagioclase in nature. A small amount of medical zirconia remained in zirconium after cleaning and processing α The penetration depth of the residual ray is very small, only 60 microns.

2. High density and strength. (1) The strength is 1.5 times higher than the second generation of EMPRESS. (2) The strength is more than 60% higher than that of INCERAM alumina. (3) Unique crack resistance and strong curing performance after fracture. (4) More than 6 units of porcelain bridges can be made, which solves the problem that all all-ceramic systems cannot be used as long bridges.

3. The natural feeling of tooth color and the inconspicuous crown edge are also the benefits of using zirconia all-ceramic restoration. Especially for patients with high aesthetic requirements, more attention should be paid to the advantage of natural color, because this makes the prosthesis and healthy teeth integrated, which is difficult to distinguish.

4. Do you know? If the denture inlaid in your mouth is a porcelain fused to metal crown, it will be affected or even removed when you need to do skull X-ray, CT and MRI. Non-metallic zirconia has no barrier to X-ray. As long as the zirconia porcelain fused teeth are inserted, the false teeth need not be removed when the skull X-ray, CT and MRI are needed in the future, which saves a lot of trouble.

5. Zirconia is an excellent high-tech biomaterial. Good biocompatibility, superior to various metal alloys, including gold. Zirconia has no irritation and allergic reaction to gums, so it is very suitable for use in the oral cavity, avoiding adverse reactions such as allergy, irritation and corrosion caused by metal in the oral cavity.

6. Compared with other all-ceramic restorations, zirconia has the advantage of strength, which enables doctors to achieve extremely high strength without too much grinding of the patient's real teeth. Vita all-ceramic plus yttrium plus stabilized zirconia is also known as ceramic steel

7. Zirconia porcelain teeth are of high quality, which is not only because of the expensive materials and equipment, but also because they are made by using the most advanced computer-aided design, laser scanning, and then controlled grinding by computer program.

8. Based on the above advantages, zirconia has become a favorite of thousands of people. Looking forward to the future, this high-quality ceramic material will become the trend of dental cosmetic repair in the future. I also hope that you who are troubled by oral diseases can really smile more brightly

All-ceramic tooth is a high-tech inlay method developed in recent years. It is to make an internal crown on the root of the treated tooth. The internal crown is a layer of all-ceramic transparent support skeleton, and then bake a layer of porcelain powder with the same color as the natural tooth on its external crown surface, and finally bond it to the tooth.

All-ceramic teeth have a wide range of indications, which can be used to repair serious oral dentition irregularities, dental crevices, tetracycline teeth, fluorosis, deformed teeth and various unfilled roots through porcelain. In recent years, all-ceramic porcelain tooth restoration has become a new fashion in modern tooth beauty, especially for people with severe tetracycline teeth and tooth loss.
